RCOphth NOD National Cataract Audit Year 7 annual report
Source: data.gov.uk (2025-12-18)

RCOphth NOD National Cataract Audit Year 7 data. The data is for the sixth prospective year of the National Cataract Audit corresponding to the 2022 NHS year (01/04/2022 to 31/03/2023). The data was collected as part of routine clinical care on electronic medical record systems in 177 participating centres. The three metrics used in the national cataract audit are case ascertainment and adjusted rates for posterior capsular rupture and visual acuity loss. The denominator for case ascertainment was the number of cataract operations reported to NHS digital or Digital Health and Care Wales (DHCW) performed using phacoemulsification. Operative data is more consistent than postoperative data as not all centres use the electronic medical record systems in all areas of their hospital eye service. Postoperative results do not include operations performed in the last 2 months of the audit year or for centres with <50 eligible operations in the postoperative time period. Visual acuity estimates are only produced for centres with at least 50 eligible operations with the relevant visual acuity measurement. Comprehensive information regarding the eligibility criteria used in the National Cataract Audit can be found on the audit website (www.nodaudit.org.uk). Results are provided for contributing NHS Trusts, Welsh Health Boards, Independent Sector Treatment Centres (ISTC), one private sector provider centre and one centre from Guernsey. The results for Bradford Teaching Hospitals NHS Foundation Trust include patients from Airedale Hospital NHS Foundation Trust as cataract surgery for Airedale patients is performed in Bradford Teaching Hospitals NHS Foundation Trust sites. Results for Moorfields Eye Hospital NHS Foundation Trust include data for patients treated in Bedford Hospital from the Bedfordshire Hospitals NHS Foundation Trust and data for patients treated in the Croydon Health Services NHS Trust.

Anyone reading this report will undoubtedly be impressed by the huge increase in scope of the
National Ophthalmology Database (NOD) cataract audit over the past 13 years. In 2010 the audit
assessed 68,107 cataract operations performed at 42 centres. This year, it reports on 481,530
operations performed at 177 centres, including independent treatment centres, between April 2022
and March 2023. This growth is both a testament to dedication of the National Ophthalmology
Database team, and evidence of the widespread recognition by clinicians, participating centre and
commissioners of healthcare of the value of the NOD as a measure of quality of cataract services.
Crucial to the success of the audit has been its selection of two key patient centred outcome
measures:
• Posterior capsule rupture (PCR) is both an internationally recognised marker of quality
of surgery, and the most important risk factor for serious postoperative complications
including retinal detachment and endophthalmitis. Since 2010 the PCR rate has fallen
by 58% to 0.79%.
• The risk of surgery related visual loss is, understandably, a key concern for people
contemplating cataract surgery. Since 2010 the risk of visual loss has fallen by 31% to 0.48%.
The significant improvements in these outcome measures are due, at least in part, to clinicians and
treatment centres reflecting on quality of their practice and, where necessary implementing change.
They also reflect continuing development of phacoemulsification equipment by manufacturers.
This report does highlight some areas of concern and scope for improvement. Only 64.4% of
operations had both pre- and post-operative visual acuity data documented. This is surprising
given that the majority of centres use electronic medical records as their only documentation of
patient care. The low figure also reflects a need to improve communication between primary and
secondary care. Another area of concern is the significant reduction in the proportion of operations
performed by trainees as compared to pre-COVID. This is undoubtedly affecting training and risks
compromising the safety and quality of future cataract services.
Crucial to the value of the cataract audit is the dissemination and use of the data it supplies.
Patients and those providing cataract services are encouraged to review and reflect on individual
surgeon’s and treatment centre’s results on the NOD website nodaudit.org.uk. Clinicians should
incorporate a discussion of NOD key outcome measures as part of the consenting process. They
should also use patient specific PCR risk calculations as recommended by NICE cataract surgery
guideline (NG77).
The NOD is now an established tool for the assessment of the quality of cataract services. It will
continue to evolve, with the eventual aim of complete United Kingdom coverage. It will remain
patient focussed and seek to use the data it provides to drive quality improvement.
My thanks go to the NOD audit team.

1. Introduction
1.1 Context
Cataract surgery remains the most frequently undertaken NHS surgical procedure with approximately
608,000 publicly funded cataract operations undertaken in England and 16,000 in Wales during the
2022 NHS year. The annual cost to the NHS of cataract surgery is estimated at around £600 million.
Included in this seventh prospective report are operations undertaken between 01 April 2022 and
31 March 2023 which corresponds to the 2022 NHS year.
As a quality assurance process, the RCOphth NOD cataract audit seeks to ensure standards are
maintained regarding the rates of Posterior Capsule Rupture (PCR) and Vision Loss, as defined below
(section 1.3). Since the original proof of concept of a national cataract audit in 2010, there has been
around a 58% reduction in recorded PCR and a 31% reduction in assessable Vision Losses in cataract
surgery, (Figure 1, page 9 and Table 1, page 10) equating to approximately 7,000 fewer complications
annually across the NHS; this conveys an estimated annual saving of around £3.5 million from avoided
additional treatments.
In this report we show the case complexity adjusted rates of PCR and monocular Vision Loss for named
centres (including all surgeons) which are also available on the NOD website; centre results are also
provided to the Care Quality Commission (CQC).
National audit is dependent on adequately complete data submission; incomplete data will therefore be
highlighted and where <60% of outcome data are available for Vision Loss, the rate will not be reported
as deemed too unreliable.
The audit brief is to include all cataract surgery where permission for inclusion of the institutions’ data
has been provided by clinical leads / medical directors and Caldicott Guardians or a governance
equivalent for centres from a region where Caldicott Guardian approval does not apply.
1.2 Aims
The audit is intended to quality assure cataract surgery for patients whose vision is adversely affected by
cataract to the point where they seek and undergo surgical intervention. Should performance fall short
of what can reasonably be expected by patients, this is highlighted. In addition, the audit serves as a
powerful driver of quality improvement with year-on-year reductions in complication rates as evidenced
in our series of annual reports available at nodaudit.org.uk/public/publications.
The audit reports risk-adjusted rates for two primary patient safety outcomes: PCR and Vision Loss in
cataract surgery. PCR will have high levels of data completeness for all participating centres as recording
of the absence or presence of specified operative complications is mandatory in ophthalmology
EMR systems. The preoperative risk indicator and follow up VA data are, however, expected to be less
complete because of variations in patient pathways and use of the EMR in different settings.
The quality improvement aims of this report include:
• Reporting of the intraoperative risk adjusted PCR rates, emphasising the need for careful
risk profiling of cases in advance of surgery to anticipate and minimise avoidable surgical
complications
• Reporting the rates of Vision Loss, highlighting potentially avoidable visual harm where
unwarranted variation is observed
5
2024/NOD/473

There are several secondary aims developed throughout the life of the audit, for example the contextual
information includes: case complexity metrics, rates of recorded valid VA data and access (preoperative
VA) by centre and overall by deprivation.
1.3 Audit measures
The two primary outcome indicators of surgical quality are defined as:
1. Intraoperative surgical complication when there is posterior capsule rupture with or without
vitreous prolapse or zonule rupture with vitreous prolapse; these intraoperative complications
are collectively termed PCR.
2. Vision Loss (doubling or worse of the visual angle) related to surgery (equivalent to a loss of
three or more lines or 15 or more letters on a LogMAR chart).
These outcomes are presented as risk adjusted rates for centres, supported by relevant contextual
information including surgery volume, data completeness, case complexity, access to surgery and
deprivation.
The EMR data collection systems used by most contributing centres allow for real time local tracking of
outcomes by surgeons and centres. This empowers them to monitor their results locally and to detect
adverse signals early with a view to minimising patient harm through prompt action. The report includes
additional contextual information which provides centres, surgeons and the wider NHS with secondary
outcomes in terms of case complexity, access to surgery by centre, deprivation, and data completeness.
Providing risk adjusted results for centres and surgeons enables them to benchmark their own
performance against their peers and acts as a prompt to reviewing practice where outcomes are less
good. Our experience indicates that showing individual surgeons their performance stimulates them to
be more mindful of quality generally and to improve performance where needed.
1.3.1 Posterior capsular rupture
PCR is emphasised in the NICE cataract surgery guideline (NG77) in the context of surgical risk and is
similarly used as a clinical outcome (adverse event) by the International Consortium for Health Outcome
Measurement (ICHOM). This operative complication arises on average in approximately one operation
in 100, but the risk of this event varies by as much as fifty-fold depending on preoperative risk factors
associated with the patient (e.g. age) and their eye (e.g. how advanced the cataract is).
PCR is relevant as an adverse operative event because it results in a significantly higher risk of harm to
the eye and may impact recovery of vision. Where PCR occurs, there is an approximate:
• 20-fold risk of a retinal detachment in the year following surgery
• 17-fold risk of acute intra-operative supra-choroidal haemorrhage
• 16-fold risk of losing ≥0.6 LogMAR from pre- to postoperatively
• 7-fold risk of post-operative endophthalmitis
• 6-fold risk of losing ≥0.3 LogMAR from pre- to postoperatively
1.3.2 Vision Loss
Vision Loss from surgery is the opposite of the intended effect; these key primary outcomes together
capture relevant safety elements of surgical quality. Vision Loss is emphasised in the NICE cataract
surgery guideline (NG77) in the context of surgical risk.
6
2024/NOD/473

Determination of Vision Loss depends on availability of VA measurements at both pre- and
postoperative time points. Rates of missing VA data are thus important and are reported for centres.
The overall rates of 1.10% for PCR and 0.90% for VA Loss which are used for risk adjustment of outcomes
were set in the second prospective audit year from the underlying unadjusted rate for consultant
surgeons. This is the final annual report for which these will be used as the reference values as the PCR
risk adjustment model has been refitted, and this new model will be implemented for the 2023-24 audit
year with updated reference values.

2. Key Findings
2.1 Participation
In this report, most centres were in England (172) with four centres in
Wales, and one centre from Guernsey. This report includes 135 currently
EMR enabled centres and 42 centres using an in-house or bespoke data
collection system. Of the 114 eligible NHS organisations in England and
Wales, 73 (64.0%) are represented, plus data from nine independent sector
treatment providers of NHS funded services (102 sites), one centre from
Guernsey and one private provider. One NHS trust and one independent
sector treatment provider (22 sites) contributed data including both NHS
funded and private fee-paying surgery. Results for 177 centres are reported.
For the 2022 NHS year, 608,120 cataract operations performed using
phacoemulsification were reported to NHS Digital from English centres and
16,338 operations from Welsh Local Health Boards. The audit received data
for 496,031 NHS funded cataract operations performed in England and
Wales using phacoemulsification, which equates to approximately 79.9%
of these cataract operations during the 2022 NHS year.
Around 4% of cataract operations were excluded for a variety of reasons
such as being done for indications other than visual improvement or being
combined with other significant intra-ocular surgery; this left 481,530
eligible cataract operations available for analysis.
2.2. Data Quality
Data completeness was excellent at around 100% for the PCR outcome
of reported operations as this is a compulsory operative field in the EMRs.
An eligible preoperative distance VA was recorded for 85.5% of eyes and a
postoperative VA for 69.0% of eyes; 64.4% of eyes had both a preoperative
and a postoperative VA measurement. There was significant variation
between centres for completeness of VA data, reflecting variations in EMR
use, patient pathways and service recovery after the service disruption
from the COVID 19 pandemic in the 2020 NHS year.
2.3 Posterior Capsular Rupture
For all surgeons, 0.79% of operations were recorded as affected by PCR.
This is approximately 58% lower than in 2010.
2.4 Vision Loss
A ‘good’ postoperative VA of 0.30 LogMAR (=6/12, required to drive)
or better was achieved in 91.8% of eyes overall, 95.8% of eyes with no
ocular co-pathology and 86.2% of eyes with a recorded co-pathology.
The median preoperative VA was 0.40 LogMAR units (6/15 Snellen
equivalent); the median postoperative VA was 0.10 LogMAR units
(6/7.5 Snellen); and the median change in VA was a 0.30 LogMAR gain.

2024/NOD/473

Over the period in table 1, not all centres have contributed data in consecutive data extractions and
some centres have merged. The first audit year ran from 01 September 2015 to 31 August 2016, years 2,
3 and 4 running from the respective months in 2016/17, 2017/18 and 2018/19. Since year 5, the audit year
is aligned with the NHS year, 01 April to 31 March. Centres when first submitting data will not always
include data for a complete year and there is often a lead time affecting data collection once a centre
adopts electronic data collection. When a centre submits data for the first time, they have the option
of submitting historic data from 01 April 2010 onwards which is then used in results for historic time
periods and increases the number of centres with data for an individual year.
Figure 1: Unadjusted PCR and VA Loss rates for each NHS year
Overall, the assessable Vision Loss rate was 0.48%, approximately 31%
lower than in 2010. The samples used for the Vision Loss results is smaller
than those used for the PCR results due to missing presenting (pre-) and / or
postoperative VA measurements, and because operations performed in the
last two months of the audit year are not included in this analysis (as this
would then require us to wait until October before extracting data to allow
six months follow up time to elapse.

* The estimate of the proportion of cases submitted to the audit is derived from the number of completed cataract operations supplied to NHS Digital or DHCW for the audit period.
This estimation uses a pro rata calculation for a centre’s denominator where the proportion of time during the audit cycle that a centre had been recording cataract operations
was multiplied by the number of cataract operations supplied to NHS Digital or DHCW. The numerator was the number of operations a centre had supplied to the audit. Centres
that had more operations submitted to the national audit than in the NHS Digital or DHCW data were all assumed to have a complete submission rate as the actual rate was not
possible to estimate. Case ascertainment rates have not been estimated for the 2010 to 2015 NHS years due to the audit not receiving the NHS Digital or DHCW data for these years.

2024/NOD/473

3. Summary
1. Over 79% of NHS funded cataract operations performed in England and Wales are now captured
by the audit with strong interest in participation being expressed from both Northern Ireland and
Scotland. Good progress has been made in terms of expanding the number of centres in successive
audit years, with 177 centres in this report including 71 English NHS trusts, two Welsh Local Health
Boards, nine independent sector treatment providers reporting 102 sites, one centre from Guernsey
and one private provider.
2. Named fully qualified surgeons and centre results are available on the NOD Audit website.
3. Established markers of surgical quality – PCR and Vision Loss – are used as metrics for risk-adjusted
outcomes. PCR is the most important intraoperative complication and is associated with increased
postoperative loss of vision. Vision Loss is intended to capture all eyes where there has been an
adverse outcome, whether or not associated with PCR. For neither outcome were any surgeons
or centres identified that were more than 3 standard deviations above the national threshold rate
in the 2022 NHS year.
4. Overall, PCR has reduced by around 58% and Vision Loss by 31% since 2010, Figure 1 (page 9)
and Table 1 (page 10). The reduction in PCR complications in cataract surgery since 2010 equates
to approximately 7,000 fewer complications annually across the NHS. Cost savings from avoided
PCR complications are estimated at approximately £3.5 million per annum and the avoidance
of Vision Loss can have multiple benefits for a patient due to the importance of vision in daily life.
5. The proportion of eligible cataract operations reported to the audit that were performed by
trainee surgeons has decreased from 21.9% in the 2018 NHS year to 11.5% in the 2022 NHS year.
This is influenced by the increased representation in the database of high-volume consultant-
delivered services which did not provide surgical training during this period. Both the numbers
of cases available for training and the complexity of cases operated in training institutions need
monitoring to safeguard training for future generations of qualified surgeons and the long-term
sustainability of cataract services.
6. Case ascertainment overall, at most contributing centres, is high although there remain some
notable exceptions (Appendix K, page 56 and Appendix Q, page 89).
7. Data completeness of reported surgery is excellent for PCR (100%), though less so for VA,
particularly for postoperative VA. Several centres and surgeons record VA data on fewer than 60%
of their cases, so cannot be evaluated for this outcome measure. The collection of this important
postoperative data should generally be improved (Appendix L, page 64 shows the VA data
submission rates for each centre).
8. Quality improvement drivers in this audit take the form of risk-adjusted results for surgical
complications and vision loss from before to after surgery. These key measures are risk- adjusted,
to acknowledge case complexity and provide credit to surgeons and centres undertaking complex
work. Without conscientious completion of risk factor data, surgeons and centres run the risk of
not being given credit for the complexity of the work undertaken. An important message for
participants to take on board both when planning surgery and when recoding their patient notes.
11
2024/NOD/473

9. The audit is aligned to, and is driving, the NHS digital agenda in the move toward electronic
working in ophthalmology. This is exemplified by the 196 centres who have submitted data for
at least 50 eligible operations in one of five NHS years’ results which are listed in appendices.
Data from 146 of these centres was submitted from EMR systems and from in-house databases
for the remaining 50 centres. From the centres that have not yet signed-up to participate, it is
known that many have not yet adopted an EMR, and some are implementing one which will then
enable national audit participation. Most of these centres collect their data as part of routine
clinical activity with no additional effort required for submission of data to the audit. Furthermore,
the EMR audit tools allow for real time tracking of adverse surgical events locally which facilitates
monitoring of complications by centres and surgeons. In the event of an adverse signal becoming
apparent, timely corrective action can be taken to avoid unnecessary harm to patients and avoid
centres or surgeons being identified as outliers in national audit reports going forward.
12
2024/NOD/473

4. Conclusions
• The current report provides assurance that delivery of NHS and publicly funded cataract surgery
in the 177 participating centres is of overall good quality.
• It is encouraging to note that since 2010, when this work feeding back cataract surgical results
to centres and surgeons began, there has been around a 58% overall reduction in recorded PCR
complications and a 31% reduction in assessable Vision Loss. Progress with quality improvement
thus far is providing obvious benefits to over 7,000 patients annually in terms of reduced
morbidity as well as significant NHS cost savings from avoided complications of around
£3.5 million annually.
• The audit aspires to include all providers of publicly funded cataract surgical care, who are
accountable to the public for the quality of services they provide. It is pleasing to note that nine
independent sector treatment providers with 102 sites are included in the current report. Until all
centres join, there will remain uncertainty about national cataract surgical outcomes, and the
risk remains that unwarranted variation in surgical quality exists in centres not participating in
national audit.
• New outcomes are being considered in order to provide a broader, more patient focused and
more easily interpreted assessment of NHS service quality in cataract care.
• The service recovery since the COVID-19 pandemic is illustrated by a return to a more even
proportion of operations performed in each month of the 2022 NHS year, Figure 22 (page 47).
For the 2021 and 2022 NHS years, the proportion of operations performed in each month are
more similar to the equivalent month’s proportions for the 2018 and 2019 NHS years, than to the
2020 NHS year which was severely affected by service disruption due to the COVID-19 pandemic,
Table 5 (page 47).
• The proportion of operations reported to the NOD that were performed by trainees has almost
halved between 2018 and 2022. This may not be fully representative of the national situation but
does represent a cause for concern for publicly funded cataract service provision which requires
investment in training to be sustainable.
• Despite the overall encouraging results of the National Cataract Audit, we cannot be confident
that poor visual outcomes are not being hidden by the variation between centres in the
completeness of visual acuity data recording; improvements in the recording of this data
would lead to less uncertainty for visual acuity results.

2024/NOD/473

2.1 All providers of NHS
cataract surgery should
submit data to the audit
to publicly demonstrate
their commitment to high
quality care and good
professional practice through
participation.
2.2. Providers should
reflect on their centre level
data from this report and
agree action points to drive
quality improvement in their
cataract service and data
collection. To facilitate this,
a RCOphth NOD cataract
audit PowerPoint slides are
available on the NOD website
to facilitate centre-specific
presentation of results.
2.3. Providers should submit
complete data including
all relevant risk factors for
outcomes to ensure case
complexity can be taken
into account and results
appropriately interpreted
(UK Minimum Cataract
Dataset for National Audit).
2.4. In line with the NHS
Digital Agenda, providers
should use electronic data
collection to improve data
completeness and utilise EMR
audit tools for continuous real
time monitoring of results for
early detection and correction
of possible issues.
2.5. Providers should
review patient pathways
to maximise the recording
of both preoperative and
postoperative VA data for
every operation and should
aspire to routine collection
of postoperative refractive
outcome data.
2.6. Providers should
consider including Patient
Reported Outcome Measures
(PROMs) before and after
surgery to quantify and
validate patient benefit from
surgery, as advised in the
2019 NICE Quality standard
for serious eye disorders
(QS180).
2. Recommendations
for Providers of
cataract surgery
1.1 Patients, carers and those
with an interest in cataract
surgery are encouraged to
access information about the
quality of cataract surgery
and their local services
and can view information
online on the National
Ophthalmology Database
Audit website.
1.2 Patients whose local
cataract provider is not
participating in the national
cataract audit could
contact their hospital via
the PALS service to inquire
about the reasons for non-
participation, and request
information on the quality
of outcomes to compare
with national benchmarks.
1. Recommendations
for Patients
5. Recommendations

2024/NOD/473

2.7. EMR enabled providers
should review the settings
on their EMR regarding
mandatory data collection.
Specifying mandatory
collection for specific data
items aids in improving data
collection. Surgeon GMC
number recording should
be mandated as this is the
legal clinical record. Trainee
surgeon details on EMR
should be verified annually
to ensure the training grade
is accurately recorded.
2.8. Surgeons working in
non-participating centres
should approach their senior
management teams and
emphasise the importance
of participation, pointing
out the benefits in terms of
quality assurance, quality
improvement, accountability,
public perception and
validation to commissioners
of the service being provided.
3.1 Commissioners should
use quality focused service
specification contracts with
providers of cataract surgery
which include submission
of full data to the RCOphth
NOD audit, including
pre- and postoperative VA
for visual outcomes. This
applies to NHS providers and
independent providers of NHS
cataract surgery, and is part
of the NHS England’s 2022
Supplementary Cataract
Contracting guidance.
3.2 Services where
postoperative care is
outsourced, e.g. to optometric
practices should require return
of postoperative data (VA and
refraction) to the operating
centre using the data return
audit tools available for such
purposes.
3.3 Cataract service providers
not participating in the
RCOphth NOD Cataract
Audit should be asked to
provide justification for non-
participation. Non-participant
providers should be required
to undertake their own quality
assurance for all surgeons
and centres based on national
benchmarks, as indicated in
the NICE cataract surgery
guideline (NG77), report the
findings to commissioners and
make the results of this quality
assurance publicly visible.
3. Recommendations
for Commissioners
15
2024/NOD/473

4.1 Regulators should expect
NHS cataract service providers
to participate in the NOD
Cataract Audit or to provide
a rationale for their decision
not to participate. This is
obligatory in England as
the NOD Cataract Audit is
included in the NHS England
Quality Accounts List.
4.2. Regulators should access
the RCOphth NOD audit
results for centres and their
surgeons when inspecting
NHS organisations which
either commission or deliver
cataract surgery services.
4.3. Regulators should ensure
that all providers of NHS
cataract surgical care are
undertaking quality assurance
regardless of whether they
are traditional NHS centres or
independent providers, even
if they are not participating in
the RCOphth NOD National
Cataract Audit
4. Recommendations
for the Regulators

2024/NOD/473

6. Future of the audit
• The audit relies on the contribution of data and funding from participating centres augmented
by donations from industry, and while this continues the RCOphth plan to continue to run the
national cataract audit
• The next data extraction planned for June/July 2024 will form the basis of the eighth prospective
annual NOD report
• Future NOD extractions will be conducted later in the year than at present, to allow all
postoperative results to include the complete reported NHS year
• Electronic data collection for cataract surgery is being implemented in Northern Ireland with
participation in the audit from Northern Irish centres commencing once EMR implementation
is complete
• National procurement projects are in place in Wales and Scotland to provide centres with an
EMR. This will allow participation in the NOD audits for all centres in Wales and Scotland
• Patients are undergoing cataract surgery at increasingly early stages of disease progression with
better visual acuity; the RCOphth NOD is therefore committed to promoting collection of patient
reported outcome measure (PROM) for cataract surgery, with feasibility studies for CatPROM5
integration into EMR currently under way
• In 2023, the RCOphth NOD published the first report from the national wet age-related macular
degeneration audit. Many centres are now participating in both audits
• The RCOphth NOD have applied for section 251 exemption to allow submission of the patients
NHS number which would enable linkage of data from patients presenting with complications
or treated in multiple centres
• The PCR model used in case complexity adjustment in the audit has been re-fitted, and this
updated model will replace the existing model for audit year 8
• The risk factor model used in case complexity adjustment for Vision Loss will be reviewed when
resources allow

Appendices
These appendices contain the full audit methodology and detailed findings on which the
recommendations. Further information is also available on the NOD website.
Appendix A: Audit Framework
This report covers adult phacoemulsification cataract surgical operations recorded on:
• Medisoft EMR in use at 127 contributing centres
• Open Eyes EMR in use at six centres
• Medisoft and OpenEyes EMR used in one centre
• Epic patient record system in one centre
• In-house cataract or bespoke data collection systems used in 42 contributing centres
For the PCR outcome, the audit included all reported cataract operations performed in the period
between 01 April 2022 and 31 March 2023. For the risk adjusted Vision Loss outcome, postoperative
complications and postoperative visual acuity results, the reported period was 01 April 2022 to
31 January 2023 to allow time for postoperative data to become available following recovery from
surgery. Inclusion and exclusion criteria are detailed in Appendix I (page 51).
Excluded were:
• Cataract operations not done by phacoemulsification
• Operations done as combined procedures along with another significant intraocular procedure
(e.g. a trabeculectomy, minimally invasive glaucoma surgical procedure or a pars plana
vitrectomy combined with other vitreoretinal procedures)
• Operations done on eyes previously damaged by ocular trauma
• Operations on polar cataracts
• Operations on eyes with significant congenital or developmental abnormalities
• Operations on individuals aged <18 years
Centres are identified by name in appendix tables.

Appendix B: Methodology
B.1 Context of the data collection
The audit data derive from routine data collection in ophthalmology departments providing cataract
surgery. Most contributing centres collect this data with no additional effort required by staff due
to the integration of EMR systems into the hospital eye service, while some centres without an EMR
collect data does require additional effort from staff. Our approach aligns directly with, and powerfully
supports the NHS digital agenda, and has catalysed a major shift towards electronic working in
cataract services. Complications’ data depend on surgeons recording these faithfully. Unlike mortality
figures, there is no external validation of the reported complications, although cross-checks are
undertaken within the extracted data, as intra-operative complications can be inferred from post-
operative findings or the need for subsequent surgery.
The EMR requires the surgeon recording the operation note to specifically indicate a ‘Yes / No’ response
to whether a surgical complication occurred. At all centres the EMR record (or its printed copy for the
paper notes) constitutes the medicolegal document of the patient’s operation record.
Data completeness for other aspects of care varies between centres for several reasons. Some centres
only use the electronic data collection system in theatre, which limits data completeness for items
normally collected in the outpatient department at pre- and postoperative visits. Accurate follow
up data on VA and refraction mostly depend on patients attending their optometrist for updating
of spectacles following surgery and for this information to then be returned to the hospital EMR
system. Although some centres have good alternative systems to an EMR in place for optometrists
to return postoperative VA and refraction measurements, and for staff at the hospital to enter the
data electronically, it is to be expected that this VA outcome will be incomplete in many centres. The
audit team has taken steps to enhance returns from optometrists through encouraging proactive
local engagement with community optometrists, an active programme of engagement with national
optometric professional bodies, and provision of a web-based data return tool for the National
Cataract Audit. Centres which have newly adopted an EMR can have a ‘time lag’ affecting complete
implementation of the software across their hospital eye service, for example due to computer
availability in theatres and implementation of electronic data recording in the eye service. This can
affect the data in their first submission to the audit.
B.2 Case ascertainment
An estimate of the percentage of cataract operations submitted to the audit is based on the number
reported centrally to NHS Digital or Digital Health and Care Wales (DHCW). This is calculated pro rata
for recent joiners, as reported in Appendix K (page 56).
As the National Cataract Audit has exclusion criteria, the estimate of case ascertainment is calculated
using the number of operations performed using phacoemulsification submitted to the audit before the
exclusion criteria are applied.
B.3 Data quality and completeness
Among the advantages of EMR data collection are compulsory collection of key data items (e.g.
operative complications) and automatic range checking of variables (e.g. axial length) at the time
of data entry. This improves data completeness and accuracy. In addition, the richness of EMR data
provides a more complete picture of the patient and their state of health making it possible to infer
important information through cross-checking.
19
2024/NOD/473

Completeness of preoperative VA and postoperative VA outcome remain variable and an area for
improvement in many centres. The audit tools include a web-based data return tool for use by
community optometrists which is intended to facilitate return of postoperative data. This works best
when optometrists are commissioned to undertake postoperative follow up in the community as
contracting can make payment contingent upon data having been received by the surgical centre.
B.4 Small numbers policy
Centres with <50 eligible operations have not been included in this report. For estimates of vision,
data from centres with <50 eligible operations with a visual acuity measurement are not included,
and for postoperative data no results are produced for centres with <50 eligible operations within the
postoperative period.
B.5 Outliers policy
The full audit outliers’ policy is available on the NOD Audit website. From this one-year audit report
data, an outlying centre or surgeon is identified where the risk-adjusted adverse event rate is above the
national threshold rate plus approximately three Standard Deviations (3SD); this outlier definition is
consistent with all national audits mandated by NHS England.
B.6 Limitations of the data
The NOD includes data for cataract surgery to the first treated eye, the second treated eye and in some
cases immediate sequential bilateral cataract surgery (ISBCS), but for some patients the record for the
first treated eye may be missing. This may arise for example if the first eye operation was performed
prior to the centre adopting electronic data collection, or in a different centre. At present the NOD
cannot link patients’ data if collected at different centres.
When centres change data collection system during an audit year, the audit will receive data from two
systems and not be able to match the records of patients with data on both systems. This will impact
on the centres results, especially for visual acuity as the preoperative VA measurement could be on
one system, and the postoperative VA measurement on the other system. This year the audit results
do include data from three centres that changed EMR during the audit year, and the audit is aware of
many other centres in the process of changing data collection systems.
Patient’s age, and the calculation of the index of multiple deprivation data rely on data entered directly
onto the Hospital’s Patient Administration System (PAS), which links into EMR systems, hence if this
data is not recorded in the PAS it is not present in the data extract for EMR enabled centres with PAS
connections. Centres using in-house databases can supply this data if they match their clinical data to
the national indices before submitting to the audit. Deprivation data was available for most operations
recorded on the Medisoft EMR system, and from one in-house database centre, but not for the other
sources of data. The RCOphth NOD is working with providers of EMR systems to facilitate the inclusion
of deprivation data during extraction, and the audit has provided information to non-EMR centres on
how they can submit deprivation data without transferring the patients’ postcode.

2024/NOD/473

Appendix C: Definitions
C.1 Dataset
A minimum cataract dataset has been defined for purposes of the audit. These variables include those
required for case complexity adjustment of outcomes.
C.2 Surgeon grade
The grade of surgeon was categorised as consultant surgeons, career grade non-consultant surgeons
(associate specialists, staff grade and trust doctors), experienced trainee surgeons (fellows, registrars,
speciality registrars years 3 – 7 and specialty trainees years 3 – 7) and less experienced trainee
surgeons (SHO, specialty registrars years 1 – 2, specialty trainees years 1 – 2 and foundation doctors
years 1 – 2).
C.3 Posterior Capsule Rupture (PCR)
Posterior capsular rupture (PCR) is defined for the purposes of the National Audit as “posterior capsule
rupture with or without vitreous prolapse or zonule rupture with vitreous prolapse” and abbreviated as
PCR. It should be noted that the definition excludes zonule dehiscence where no vitreous prolapse has
occurred. PCR is thus intended to capture significant breach of the lens-zonule barrier. Detailed criteria
for case definitions is in Appendix I (page 51) and on the audit website.
C.4 Visual Acuity (VA)
VA definitions used were designed to maximise the usefulness of the available data with specified
‘time windows’ for pre- and postoperative measurements and criteria for preferred choices in terms of
corrected VA, unaided VA and pin hole corrected VA. The detailed criteria is in Appendix I (page 51) and
on the audit website along with interpretations for levels of VA. The percentage of eyes with VA data for
each centre and different time windows are given in Appendix U (page 114).
C.5 Mixed effects modelling of PCR and Vision Loss
The categorisation of each covariate under investigation in the PCR and Vision Loss mixed effects
logistic regression models are detailed for registered users on the NOD Audit website with operations
performed in the four-year period 2011-12 to 2014-15 NHS years used to develop the current models.
The risk adjustment model equations for PCR and Vision Loss respectively were applied to the audit
data for the respective results in this report where the case mix adjusted graphs have 95% and 99.8%
error lines displayed which are created from the overall consultant rates observed in previous years,
these values are 1.1% for PCR and 0.9% for Vision Loss. The audit stipulates that at least 50 eligible
operations are required for a centre or surgeon result, and at least 60% of operations with both pre-
and postoperative VA data are required to report a result for Vision Loss. On the centre level case mix
adjusted funnel plots, data for all surgeons is included (i.e. including trainee surgeons whose results
are risk adjusted accordingly).
C.6 Case complexity index
Based on the risk prediction models a case complexity index is provided for each centre. This is taken as
the overall predicted probability of an adverse outcome based on the reported case complexity for the
centre. Separate complexity indices are provided for PCR and Vision Loss.

Appendix D: Detailed Results
D.1 Case ascertainment
In total, 502,183 operations were submitted to the audit by 180 centres, of which 499,662 (99.5%) were
performed using phacoemulsification. The estimate of case ascertainment is made by comparison with
data from NHS Digital and DHCW. Three centres were excluded from the cataract audit analyses due
to supplying <50 eligible operations, two centres are not subject to reporting to either NHS Digital or
DHCW and 18 centres did not have any data available from NHS Digital.
The overall case ascertainment for the 157 centres eligible and where case ascertainment could be
estimated was 96.0%. The case ascertainment rate was >90% for 143 (91.1%) centres. The range in the
percentage of cases submitted to the audit was 3.5% to 100%, Appendix K (page 56), and the case
ascertainment for centres for the 2018 - 2022 NHS years is in Appendix Q (page 89).
Of the 502,183 operations submitted for the 2022 NHS year, 20,595 (4.1%) operations are excluded from
analysis and a further 58 operations from three centres are excluded due to these centres submitting
data for <50 eligible operations; the eligibility information is on the RCOphth NOD Audit website: NOD
Audit Eligibility Criteria. This left 481,530 operations performed in 177 participating centres eligible for
analysis. The operations were performed on 239,281 (49.7%) left eyes and 242,249 (50.3%) right eyes
from 367,515 patients.
Of the eligible cataract operations, 477,340 (99.1%) were performed in English centres, 3,679 (0.8%) in
Welsh centres and 511 (0.1%) in Guernsey. From the 481,019 operations performed in England or Wales,
165,983 (34.5%) were performed in traditional NHS centres, 311,927 (64.9%) as NHS funded surgery in
ISTC sites, and 3,109 (0.7%) were private fee-paying operations.
D.2 Surgeons
The 481,530 eligible operations were performed by 2,312 surgeons where;
• 1,244 consultant surgeons performed 406,620 (84.4%) operations
• 217 career grade non-consultant surgeons performed 19,397 (4.0%) operations
• 807 more experienced trainee surgeons performed 49,615 (10.3%) operations
• 151 less experienced trainee surgeons performed 5,898 (1.2%) operations
The percentage of operations performed by each grade of surgeon varied between contributing centres
reflecting catchment area, NHS trust differences and training opportunities for junior trainee surgeons
within England and Wales, Appendix K (page 56) and Figures 2 and 3 (page 24).
The median number of operations each surgeon had performed was 65 operations (IQR; 24 – 144:
range; 1 – 7,279). For comparison, the median number of operations per surgeon was 65, 67, 34 and
57 in the 2018, 2019, 2020 and 2021 NHS years respectively. In the 2022 NHS year, 102 surgeons had
data for >1,000 operations, one surgeon had all their data from NHS trusts, 61 surgeons had all their
data from ISTC sites and 40 surgeons’ data from both NHS trusts and independent sector treatment
provider sites. In the 2022 NHS year, 1,343 (58.1%) surgeons performed ≥50 eligible operations, for
comparison these percentages were 57.9%, 59.4%, 37.9% and 53.6% for the 2018, 2019, 2020 and 2021
NHS years respectively. Of the 969 (41.9%) surgeons with <50 operations, 492 (50.8%) were consultants
or independent non-consultant surgeons, 465 (48.0%) were trainee surgeons and 12 (1.2%) had data as
both a trainee and a consultant or independent non-consultant surgeon.
22
2024/NOD/473

Of the 2,312 surgeons, 1,479 (64.0%) surgeons were male, 821 (35.5%) surgeons were female and the
gender was unknown for 12 (0.5%) surgeons. 414 (17.9%) surgeons had data for operations performed
in two participating centres, 67 (2.9%) in three participating centres and 137 (5.9%) in four or more
centres, with 41 surgeons having data for >10 centres, eight surgeons having data for ≥20 centres and
two surgeons with data for ≥30 centres. Of the 41 surgeons with data for >10 centres, 18 surgeons had
data from one NHS trust and all their other centres were all ISTC sites, and 23 surgeons had all their
data only from ISTC sites. Six of the eight surgeons with data for ≥20 centres had data from only one
NHS trust with all their other centres as ISTC sites, the other two surgeons had all their data from ISTC
sites. For two surgeons with data for ≥30 centres, one surgeon had data for 32 different ISTC sites and
no NHS trusts, and one surgeon had data for 34 different ISTC sites and one NHS trust.
The percentage of operations performed by consultant surgeons has increased since the 2018 NHS year
from 70.5% to 84.4% in the 2022 NHS year. This increase is partly due to higher representation from the
ISTC who did not provide training during these NHS years. Consequently, the percentage of operations
performed by trainee surgeons has decreased by around 47% since 2018, where 21.9% of operations
were performed by trainee surgeons compared to 11.5% in 2022. The proportion of operations
performed by male and female surgeons was consistent across the 2018 – 2022 NHS years. As the 2020
NHS year matches the period of service disruption due to COVID-19, this led to a higher proportion of
surgeons with data for <50 eligible operations and a lower proportion with ≥50 eligible operations. The
2022 NHS year proportion of surgeons with data for <50 and ≥50 eligible operations are more similar
to the 2021 NHS year and to the pre-2020 NHS year proportions (2018 and 2019 NHS years) indicating
some element of service recovery since COVID-19 severely disrupted services in 2020. The number of
surgeons with data for >1,000 operations has increased over the 2018 – 2022 NHS years. For the 2022
NHS year, approximately eight times more surgeons had data for >1,000 eligible operations than in the
2018 NHS year, and four-times more than in the 2020 NHS year, Appendix O (page 86). The increase in
the number of surgeons with data for >1,000 eligible operations is partly due to representation from the
ISTC where most of the high-volume surgeons have data for.

D.3 Patient characteristics – age and gender
Summary details of the 367,515 patients undergoing cataract surgery in the 2022 NHS year were as
follows:
• 152,957 (41.6%) patients were men
• 210,555 (57.3%) patients were women
• The gender was not recorded for 4,002 (1.1%) patients
• One patient’s gender was recorded as indeterminate / anticipated sex change
• The ethnicity was not recorded for 174,796 (47.6%) patients
• Patient characteristics were very similar for first treated and second treated eyes
D.4 First eye, second eye and ISBCS eyes
All cataract operations performed could be in either the patient’s first or second treated eye unless
ISBCS was performed. The audit may not have the record for both operations or the first treated eye
could have had the operation at another centre or prior to electronic data collection within a centre,
or the data for the first and second eye operations could be recorded on different EMR systems used
within a centre. For these reasons, no results on time between operations are provided in this report.
Results for first treated, second treated and ISBCS eyes are described below.
First treated eye cataract surgery;
• First eye cataract surgery was performed for 280,357 (58.6%) operations
• The median age at first treated eye surgery was 76.0 years (IQR; 69.4 – 81.5)
• 29,023 (10.4%) patients were recorded as having diabetes mellitus at the time of their first
cataract operation
• 3,453 (1.2%) patients were recorded as unable to lie flat
• 6,601 (2.4%) patients were recorded as unable to cooperate during the operation
• 6,119 (2.2%) patients were operated on under general anaesthesia, combined with local and/or
topical for 5,528 patients
Second treated eye cataract surgery;
• Second eye cataract surgery was performed for 197,887 (41.4%) operations
• The median age at second treated eye surgery was 76.7 years (IQR; 70.7 – 82.2)
• 21,974 (11.1%) patients were recorded as having diabetes mellitus at the time of their second
treated eye surgery
• 2,034 (1.0%) patients were recorded as being unable to lie flat
• 5,218 (2.6%) patients were recorded as being unable to cooperate during the operation
• 4,462 (2.3%) patients were operated on under general anaesthesia, combined with local
and/or topical for 4,137 patients
25
2024/NOD/473

ISBCS eyes;
• ISBCS was performed for 1,643 patients by 295 surgeons from 64 centres
• The same surgeon performed the operation to both eyes for 1,458 (88.7%) patients
• A trainee surgeon performed 324 (19.7%) of the operations, and for 90 (5.5%) patients a trainee
surgeon performed both eye operations
• The median age was 73.7 years (IQR; 66.0 – 79.6), with no difference between male or female
patients (mean age in years; 72.6 for males vs. 71.7 for females)
• 710 (43.2%) patients were male, 931 (56.7%) were female and the gender was not recorded for
2 (0.1%) patients
• 204 (12.4%) patients were recorded as having diabetes mellitus
• 50 (3.0%) patients were recorded as being unable to lie flat
• 42 (2.6%) patients were recorded as being unable to cooperate during the operation
• 164 (10.0%) patients were operated on under general anaesthesia, 141 combined with local
or topical anaesthesia
The patient’s age, proportions for gender, those who could lie flat and cooperate with surgery were
similar in each NHS year for first eye surgery patients and second eye surgery patients. Differences were
observed for the proportion of patients with diabetes mellitus and the proportion of patients having
surgery under general anaesthesia which are both showing signs of decreasing over the NHS years.
There were differences for ISBCS patients across the NHS years for the proportion of patients who could
lie flat and cooperate with surgery which have variable proportions over the NHS years, partly due to
small samples of patients in the earlier NHS years. The largest difference for ISBCS patients across the
NHS years was for the use of general anaesthesia which was 38.2% and 44.7% for the 2018 and 2019
NHS years which are the two pre-COVID 19 NHS years. This proportion reduced to 9.0% in the 2020 NHS
year, and around 10% since, indicating that a change to practice made during the COVID 19 service
disruption has remained since, Appendix P (pages 87).
D.5 Index of multiple deprivation
The English index of multiple deprivation was calculated for 265,984 (97.8%) patients from 125
participating English centres, with data recorded on the Medisoft EMR for 124 centres and an
in-house database for one centre. All bar two centres performed cataract surgery on patients in
the most deprived national decile of social deprivation (decile 1) and all bar two centres performed
cataract surgery on patients in the least deprived national decile of social deprivation (decile 10). The
median English national decile of social deprivation for patients undergoing cataract surgery varied
significantly between centres, confirming that there was variation between the participating centres
in the social deprivation status of patients undergoing cataract surgery, Figure 4 (page 27). The index
of multiple deprivation was not calculable for operations from the other contributing data collection
systems or from the contributing Welsh and Channel Island centres where different indices are used.

2024/NOD/473

D.6 Preoperative Visual Acuity (VA)
From the 481,530 eligible cataract operations a preoperative VA was recorded for 416,311 (86.5%)
operations and missing for 65,219 (13.5%) operations, of which 2,937 (0.6% of all operations) had a
Pin Hole VA (PHVA) measurement and no Corrected Distance VA (CDVA) or Uncorrected Distance VA
(UDVA) operations.
There was wide variation in the percentage of eyes with a preoperative VA by contributing centre,
where 13 (7.3%) centres had <50% of eyes with preoperative VA data (including two centres with no
preoperative VA data), for 133 (75.1%) centres more than 80% of eyes had a preoperative VA and for 84
(47.5%) centres more than 95% of eyes had a preoperative VA, Figure 5 (page 29).
For comparison with this 86.5% the overall percentage of eyes with a preoperative VA, the proportions
were 90.0%, 85.7%, 70.8% and 86.2% for the 2018, 2019, 2020 and 2021 NHS years respectively. The
percentage of eligible operations with a preoperative VA for contributing centres and NHS years is in
Appendix S (page 98).
From the 416,311 eyes with a preoperative VA measurement from 175 centres, the VA measurement
was CDVA in 294,439 (70.7%) eyes, UDVA in 114,601 (27.5%) eyes and in 7,271 (1.8%) eyes the CDVA
measurement was the same as the UDVA measurement.
The median preoperative VA was 0.40 LogMAR units (6/15 Snellen equivalent), and the range was
-0.30 to NPL (6/3 to NPL Snellen equivalent); where 11,154 (2.7%) eyes were CF, 8,919 (2.1%) eyes were
HM, 2,252 (0.5%) eyes were PL and 161 (<0.1%) eyes were NPL. The median preoperative VA was 0.40
LogMAR units for eyes operated on by qualified surgeons, and 0.50 LogMAR units for eyes operated on
by trainee surgeons.
Figure 4: Median and IQR national deciles of social deprivation by participating centre
27
2024/NOD/473

The preoperative VA was 0.30 LogMAR units (6/12) or better for 168,522 (40.5%) eyes, 0.60 LogMAR
units (6/24) or better for 314,714 (75.6%) eyes and 1.0 LogMAR units (6/60) or better for 378,649
(91.0%) eyes.
There was variability in the preoperative VA between contributing centres, where for 52 (29.7%) centres
the median preoperative VA was 0.50 LogMAR (6/19 Snellen equivalent) and the range in the centres
median preoperative VA was 0.00 to 0.80 LogMAR (6/6 to 6/38 Snellen equivalent), Figure 6 (page 29).
For 169 (96.6%) centres, the median preoperative VA was between 0.30 and 0.60 LogMAR.
Deprivation is recognised as an influential factor on the ability of individuals to access care for a
variety of conditions. Here we have used preoperative VA as a proxy for cataract severity to assess
whether deprivation is (or is not) related to timely access to surgery before symptoms of vision loss
become advanced. On this basis variation is observed across the Index of Multiple Deprivation (IMD) as
demonstrated on Figure 7 (page 30) and Table 2 (page 30), where there is association between higher
levels of deprivation and worse preoperative VA, for example 21.9% of the patients in the most deprived
decile (decile 1) had a preoperative VA of ≥1.00 LogMAR, compared to 10.1% of patients in the least
deprived decile (decile 10).
For 94,546 patients who had both eyes undergo cataract surgery during the 2022 NHS year with a
preoperative VA measurement for both eyes (excluding ISBCS patients), the mean presenting VA was
0.15 LogMAR units worse (95% CI: 0.148 to 0.154 LogMAR) for the first treated eye than for the second
treated eye (means = 0.55 (6/21) and 0.40 LogMAR (6/15) respectively, p <0.001). This implies that first
eye surgery is generally undertaken at a more advanced stage of cataract than second eye surgery.
For 1,523 ISCBS patients with a preoperative VA measurement for both eyes, the median difference in
the VA between the better and worse vision eye was 0.00 LogMAR units, and for 557 (36.6%) patients
the preoperative VA was the same in both eyes.

D.7 Ocular co-pathologies and risk factors
The presence or absence of an ocular co-pathology or known risk factor was recorded for 94.0%
of operated eyes and was not recorded for 6.0% of eyes. Assuming that the not recorded ocular
co-pathology or known risk factors are ‘none’, then an ocular co-pathology or known risk factor was
present in 170,902 (35.5%) eyes and recorded as absent (or not recorded) for 310,628 (64.5%) eyes.
The percentage of eyes with ocular co-pathology or known risk factor data recorded (any, none
or not recorded) varied between centres, where the percentage of eyes reported to have any ocular
co-pathology ranged between centres from 0.0% to 79.1%, and 52 (29.4%) centres had >50% of
operated eyes with an ocular co-pathology, Figure 8 (page 32). Two centres had all operations
submitted with a not recorded ocular co-pathology.
The most recorded ocular co-pathologies were age-related macular degeneration, Corneal pathology,
unspecified ‘other’, and glaucoma, which were recorded for 7.4%, 7.1%, 5.6% and 5.6% of operations
respectively, Figure 9 (page 32). Consultant surgeons performed >60% of operations with each
individual co-pathology, Figure 10 (page 33).
Variation between centres in the percentage of eyes with any ocular co-pathology or known risk factor
exists in each NHS year, Appendix Q (page 89). The percentage of eyes with each of the individual
ocular co-pathology or known risk indicators has been consistent for some co-pathologies and variable
for others across the 2018 – 2022 NHS years, Appendix R (page 97).

D.8 Operation characteristics
Phacoemulsification ± IOL was the only operative procedure performed for 459,151 (95.4%) operations,
was combined with one other procedure in 20,239 (4.2%) operations, and with ≥2 other procedures in
2,140 (0.4%) operations.
The most frequently performed operative procedures combined with phacoemulsification ± IOL
were insertion of pupil ring expander, intraoperative phenylephrine and anterior vitrectomy, which
were performed in 1.4%, 0.9% and 0.5% of operations respectively. A full list of operative procedures
combined with phacoemulsification ± IOL is in Appendix V (page 122).
D.9 Operative complications
One or more intraoperative complication was recorded for 7,642 (1.6%) operations, with the most
frequently recorded being PCR which was reported for 3,786 (0.8%) operations. The ‘any’ intraoperative
complication rates were higher for the less experienced grade of surgeons, while the rates for individual
intraoperative complications were similar across the grades of surgeon for most intraoperative
complications, with some exceptions where higher rates were observed for less experienced grades,
Table 3 (page 35).
33
2024/NOD/473

D.10 Case complexity adjusted PCR results
Unadjusted for case complexity PCR rates for the 177 participating centres are shown in Figure 11 (page
36) and an adjusted for case complexity graph in Figure 12 (page 36). No participating centres were
outliers in the 2022 NHS year. Details of the unadjusted and adjusted for case complexity PCR results
for the 177 participating centres is in Appendix N (page 78), along with a case complexity index which is
the overall predicted probability of PCR for all the cases reported for each centre. The case complexity
adjusted PCR rate for contributing centres in the 2018 – 2022 NHS years is in Appendix T (page 106).
Displayed on the public section of the audit website will be case complexity adjusted PCR results for
participating centres and fully qualified surgeons (consultants and career grade non-consultants) with
at least 50 eligible operations.
Posterior capsular rupture (PCR) is defined for the purposes of the National Cataract Audit as “posterior
capsule rupture with or without vitreous prolapse or zonule rupture with vitreous prolapse” and
abbreviated simply as PCR. Retained lens fragments in the vitreous implies PCR.

D.11 Postoperative complications
To submit postoperative complication data to the audit there needs to be enough time after the
operation for patients to receive postoperative follow-up. Therefore, the audit reports on operations
performed in the first 10 months of the NHS year (before 31 January). This allows the potential for two
months’ follow-up.
Of the 481,530 eligible cataract operations submitted to the audit, 391,679 (81.3%) operations from
176 centres were performed before 31 January 2023 and had the potential for two months’ follow-
up. One centre had no operations in the postoperative qualifying time and data from four centres
(81 operations) are excluded due to these centres having <50 eligible operations in the postoperative
qualifying time period. This left 391,598 eligible operations from 172 centres available for postoperative
complication results. No postoperative complication data was recorded for 233,455 (59.6%) operations,
for 133,364 (34.1%) operations ‘none’ was recorded as the postoperative complication, and 24,779
(6.3%) operations had at least one postoperative complication recorded. The variation in data likely
reflects differences in cataract surgery patient pathways across centres.
The percentage of operations with a postoperative complication record (none or a complication), or
no postoperative complication record, varied significantly between the participating centres, with 12
(7.0%) centres having no records of any specific postoperative complications, Figure 13 (page 38).
The most frequently recorded postoperative complications were postoperative uveitis, postoperative
cystoid macular oedema (CMO), and corneal oedema / striae / haze which were the only individual
postoperative complications recorded for >1.0% of operations, Figure 14 (page 38).
For the 391,598 eligible operations for postoperative complication assessment, 388,820 were for the
patients first or second treated eye (excluding ISBCS eyes). For 229,528 first treated eyes, postoperative
CMO developed in 3,383 (1.47%) eyes, postoperative endophthalmitis developed in 41 (0.02%) eyes and
postoperative uveitis developed in 5,723 (2.49%) eyes. For 159,292 second treated eyes, postoperative
CMO developed in 2,163 (1.36%) eyes, postoperative endophthalmitis developed in 27 (0.02%) eyes and
postoperative uveitis developed in 3,804 (2.39%) eyes.
Within the 10—month postoperative complication assessment time period, 82,473 patients had
cataract surgery to both eyes (excluding ISBCS eyes). For these patients, postoperative CMO developed
in 712 (0.86%) patient’s first treated eye and 803 (0.97%) second treated eyes, with 133 (0.16%)
patients developing postoperative CMO in both eyes. Postoperative uveitis developed in 1,623 (1.97%)
patient’s first treated eye and 1,711 (2.07%) second treated eyes, with 280 (0.34%) patients developing
postoperative uveitis in both eyes. Postoperative endophthalmitis developed in only three patient’s
first treated eye and 16 (0.02%) second treated eyes, with no patients developing postoperative
endophthalmitis in both eyes.
For 1,389 patients (2,778 eyes) who had ISBCS during the 10-month time period for postoperative
assessment, seven eyes developed postoperative uveitis, no eyes developed postoperative
endophthalmitis and seven eyes developed postoperative CMO. Three patients developed
postoperative CMO in both eyes, and two patients developed postoperative uveitis in both eyes.

D.12 Postoperative visual acuity
From the 481,530 eligible operations from 177 centres, 391,679 (81.3%) operations were performed before
31 January 2023 and had the potential for two months’ follow-up. One centre had no operations in the
postoperative qualifying period and data from four centres (81 operations) are excluded due to these
centres having <50 eligible operations in the postoperative qualifying time period. This left 391,598 eligible
operations from 172 centres available for the assessment of the percentage of eyes with a postoperative VA
measurement. Of these, a postoperative visual acuity was recorded for 270,155 (69.0%) eyes and missing
for 121,443 (31.0%) eyes. For comparison the percentage of eyes with a postoperative VA were 75.9%,
73.0%, 60.9% and 67.5% for the 2018, 2019, 2020 and 2021 NHS years respectively. The percentage of
eyes with a postoperative VA for contributing centres and each audit year is in Appendix S (page 98).
There was wide variation in the percentage of eyes with postoperative VA by contributing centre; four
centres had no eyes with a postoperative VA, for 30 (17.4%) centres <50% of eyes had a postoperative VA,
for 74 (43.0%) centres >80% of eyes had a postoperative VA and for 10 (5.8%) centres >95% of eyes had
a postoperative VA, Figure 15 (page 40) and Appendix L (page 64). Influencing this result are operations
performed in the latter part of the audit period where not all patients could have sufficient follow-up for
all postoperative results to be available. Another factor is the move to patient-initiated follow-up (PIFU) as
a routine practice following cataract surgery with patients then attending community optometrists under
the General Ophthalmic Services (GOS) contract, or more constructed arrangements which still involve
discharge to the community for a commissioned follow up assessment. In either case, post-operative
measurements are not always sent back to the hospitals for recording on the hospitals’ EMR system.
Overall, the percentage of eyes with postoperative VA data was 72.4% for first treated eyes and 64.0%
for second treated eyes. The percentage of first and second treated eyes with postoperative VA data
varied between centres, where 148 (86.0%) centres had a higher percentage of first treated eyes with
postoperative VA data than second treated eyes, for 50 (29.1%) centres this difference was >10% points
and for 18 (10.5%) centres >25% points, Appendix L (page 64).
From the 270,155 eyes with a postoperative VA measurement, data from one centre (33 operations) are
excluded from the estimate of postoperative vision due to the centres having <50 eligible operations
with a postoperative VA measurement. Eligible for assessing postoperative vision are 270,122
operations from 167 contributing centres.
For the 270,122 eyes eligible for postoperative VA assessment, the best measurement was CDVA in
120,813 (44.7%) eyes, UDVA in 62,770 (23.2%) eyes, PHVA in 36,960 (13.7%) eyes; the best measurement
was the same for two of the assessment methods for 47,274 (17.5%) eyes and the same for all three
methods in 2,305 (0.9%) eyes.
The median postoperative VA was 0.10 LogMAR units (range; -0.30 to NPL) (6/7.5 Snellen equivalent);
where 706 (0.3%) eyes were CF, 513 (0.2%) eyes were HM, 98 (<0.1%) eyes were PL and 30 (<0.1%) eyes
were NPL.
The postoperative VA was 0.30 LogMAR units (6/12) or better for 247,940 (91.8%) eyes, 0.60 LogMAR units
(6/24) or better for 262,742 (97.3%) eyes and 1.0 LogMAR units (6/60) or better for 267,534 (99.0%) eyes.
The postoperative VA was stable across participating centres, although there was some variation where
the median postoperative VA was 0.00 LogMAR for 55 (32.9%) centres, 0.10 LogMAR for 67 (40.1%) centres
and 0.20 LogMAR for 16 (9.6%) centres. The overall median postoperative VA for centres was 0.10 LogMAR
with a range in the centres median postoperative VA of 0.00 to 0.30 LogMAR, Figure 16 (page 40).
Overall, VA outcomes were as expected, though data completeness remains an area for improvement
and results for centres with small numbers will be subject to significant statistical uncertainty and
potential bias.

D.13 Change in visual acuity
Of the 481,530 eligible cataract operations submitted to the audit performed before 31 January 2023.
One centre had no operations in the postoperative qualifying time and data from four centres (81
operations) are excluded from change in VA results due these centres having <50 eligible operations
in the qualifying time period. This left 391,598 eligible operations from 172 centres considered for
the reporting of the percentage of eyes with change in VA data, where 252,139 (64.4%) eyes had
both a preoperative VA and a postoperative VA measurement. Four centres had no eyes with both
a postoperative and preoperative VA, 44 (25.6%) centres had <50% of eligible eyes with both VA
measurements and 57 (33.1%) centres had >80% of eyes with both VA measurements, Figure 17 (page
42). For comparison, the percentages of eyes with change in VA data were 71.0%, 67.9%, 48.2% and
62.4% for the 2018, 2019, 2020 and 2021 NHS years respectively. Data completeness for this measure
has increased since the 2020 NHS year reflecting less service disruption in the 2021 and 2022 NHS
years. The audit will continue to encourage centres to collect and record both preoperative and
postoperative VA to allow for determination of this measure.
From the 252,139 eyes with both a preoperative and postoperative VA measurement, data from five
centres (178 operations) are excluded from the change in VA analysis due to the centres having <50
eligible operations with both a preoperative and a postoperative VA measurement. Eligible for change
in VA analysis are 251,961 operations from 163 participating centres.
The median change in VA from baseline was a 0.30 LogMAR gain (IQR; 0.20 – 0.60 gain). A loss of
>0.10 LogMAR (1 Snellen line loss) was experienced by 7,541 (3.0%) eyes, a change of ±0.10 LogMAR (±1
Snellen line) by 19,751 (7.8%) eyes and a gain of >0.10 LogMAR (1 Snellen line gain) by 224,669 (89.2%)
eyes. The change in VA was not similar for all centres with some difference’s observable, Figure 18 (page
42). Overall, most cataract surgery operations resulted in a significant improvement in visual acuity for
patients, as illustrated in Figure 19 (page 43) where for all bar two centres, the median postoperative
VA was better than the median preoperative VA.
74.7% of eyes with a preoperative VA of 0.00 LogMAR or better had a postoperative VA of 0.00 LogMAR
or better and 97.8% of eyes with a preoperative VA of 0.30 LogMAR or better had a postoperative VA of
0.30 LogMAR or better.
Eyes that had an ocular co-pathology or experienced an intraoperative complication or PCR during
surgery had worse postoperative VA than eyes that did not have any of these problems. >90% of eyes
without these problems had a postoperative VA of 0.30 LogMAR (6/12 Snellen) or better, Table 4
(page 44).
The percentage of operations from each participating centre with preoperative VA, postoperative VA
and both pre- and postoperative VA data varied between participating centres, Appendix L (page 64).

D.14 Outcomes in surgery for Severely Sight Impaired Eyes
When a person has a corrected visual acuity of less than 1.30 LogMAR with both eyes open, they
are eligible for certification as severely sight impaired. From the 251,961 eyes with both an eligible
preoperative and postoperative VA, the preoperative VA was worse than 1.30 LogMAR for 15,643 (6.2%)
eyes, where 1,153 (7.4%) of these eyes VA was still worse than 1.30 LogMAR post-cataract surgery, and
14,490 (92.6%) eyes VA had improved to a level better than the severely sight impaired certification VA
threshold. For the 236,318 (93.8%) eyes with a preoperative of 1.30 LogMAR or better, 235,942 (99.8%)
eyes VA was 1.30 LogMAR or better post-cataract surgery, and for 376 (0.2%) eyes, the postoperative VA
had decreased to the level where the person was eligible to be registered as severely sight impaired. These
results are produced only from visual acuity measurements, and if a person has visual field damage, they
can be eligible for severely sight impairment certification if their VA is better than 1.30 LogMAR.
D.15 Severe Visual Loss
The National Cataract Audit has, since inception, been reporting Vision Loss as an outcome based on
a loss of 0.30 LogMAR or more. However, for the purpose of informed consent, it is useful to be able to
cite the risk of severe loss of vision following cataract surgery. A loss of 0.60 LogMAR (quadrupling of the
visual angle), has been adopted as a level of change from preoperative to postoperative VA that could be
described as severe. Eyes with PL or NPL vision preoperatively are excluded. For the 251,961 eyes with both
an eligible preoperative and postoperative VA, the preoperative VA was HM or better for 250,569 (99.4%)
eyes; severe vision loss was experienced by 532 (0.21%) eyes. Excluding ISBCS eyes, severe VA loss was
experienced by 335 (0.22%) of 155,503 first treated eyes and in 196 (0.21%) of 93,767 second treated eyes.
For 505 ISBCS patients (1,010 eyes) severe VA loss was experienced by 1 (<0.1%) eye.
D.16 Case complexity adjusted Visual Loss results
Of the 481,530 eligible operations, 391,679 operations were performed up to 31 January 2023 and had
the potential for two months’ follow-up. One centre had no operations in the postoperative qualifying
period and data from four centres (81 operations) are excluded from the postoperative Vision Loss
results due these centres having <50 eligible operations in the qualifying time period. This left 391,598
eligible operations from 172 centres with at least 50 eligible operations in the postoperative qualifying
time period. From these, 199,763 (51.0%) operations from 104 centres were performed in centres were a
preoperative and postoperative VA was recorded for at least 60% of the operations and in at least 50
operations per centre.
An unadjusted for case complexity funnel plot of Vision Loss is shown in Figure 20 (page 46) and an
adjusted for case complexity funnel plot in Figure 21 (page 46). Details of the unadjusted and adjusted for
case complexity Vision Loss results is in Appendix N (page 78), along with a case complexity index which is
the overall predicted probability of Vision Loss for the cases reported by each centre. The case complexity
adjusted Vision Loss rate for contributing centres for the 2018 – 2022 NHS years is in Appendix T (page 106).
Centres with >40% operations without VA measurements and centres with <50 operations with both a
preoperative and postoperative VA have not been reported as the estimates would be too unreliable.
Displayed on the public section of the audit website will be case complexity adjusted Vision Loss results
for participating centres and fully qualified surgeons (consultants and career grade non-consultants)
with sufficient data for a result to be produced.
The actual observed Vision Loss rate for the year six sample was 0.48%, which is lower than the
percentage rate used for complexity adjustment. This is not an unexpected finding, as there is variation
between centres in the percentage of reported operations, percentage of operations with both
preoperative postoperative VA.

Appendix E: Acknowledgements
We would like to acknowledge the support and guidance of the NOD the NOD Steering Group,
Executive Committee, Quality and Standards Committee, Informatics and Audit Subcommittee, Lay
Advisory Group and the Cataract Audit Advisory Group, whose members are named in Table 6 (page
48). Their guidance has helped us to ensure the audit has relevance for not only the professional
readership but also patients, their relatives and carers.
We also acknowledge the support of the hospitals participating in the audit and thank our medical and
non-medical colleagues for the considerable time and effort devoted to conscientious electronic data
collection as they go about caring for their patients.
We acknowledge with thanks the contribution of Professor John Sparrow who provided diligent clinical
and academic oversight and leadership of the NOD over many years to bring it to its current stature.
It is with gratitude that we remember our friend and colleague Robert Johnston, who sadly died in
September 2016. Without his inspirational vision, determination and career long commitment to quality
improvement in ophthalmology this work would not have been possible.
12. Funding
The National Cataract Audit is funded through participation fees from centres as well as unrestricted
contributions from Alcon Eye Care UK Limited and Bausch + Lomb. We are grateful for the donations
received from these organisations. We are also grateful for specific funds provided to support individual

Appendix H: Interpreting the graphs and tables
Among the results there are five types of graphs;
1. Bar charts – these are either horizontally or vertically aligned depending on the data being plotted.
One axis displays the categorical element, usually contributing centre and when bar charts are
sub-divided by another category, the length of each bar indicates the quantity of interest for the
sub-category as read from the numeric axis. Some vertically aligned bar charts have horizontal
dashed reference lines at specific points on the y-axis, these relate to cut-off points used in the
reporting of results, for example 50%. Each bar chart is ordered (sorted) by a quantity being
plotted, i.e. percentage. Figure 5 (page 29) is an example of a bar chart.
2. Box and Whisker plots – the spread for the variable of interest is shown where the central line is the
median or ‘middle’ value. The box outlines the inter quartile range (25% and 75% centiles), and the
horizontal lines above and below the inter quartile range display either the position of the furthest
value or a value at a ‘reasonable’ stretch from the middle. Extreme values are the dots beyond that.
Figure 7 (page 30) is an example of a Box and Whisker plot.
3. Funnel plots – The spread of dots on these looks like a funnel going from left to right. Each dot
represents a result for a centre or surgeon as read off the vertical axis (proportion or rate). The
funnel effect results from increasing statistical precision as the numbers get higher going along the
horizontal axis, for example Figure 11 (page 36). Some of the plots have lines on them showing what
is expected. A result above the top line (three standard deviations) would be deemed unacceptably
high, for example Figure 12 (page 36). Statistical precision increases as the sample increases, this
is illustrated by narrower confidence intervals. When the PCR rate or Vision Loss rate for a centre or
surgeon is extremely low and they have a high number of cases, it is more likely that they will be a
positive outlier due to the narrowing confidence intervals with higher volume.
4. Median and IQR plots – These display for each contributing centre, the median and IQR for a
numeric quantity as read from the vertical axis. These estimates indicate variation between centres
and by not including the range these graphs allow magnification on the y-axis and a clearer view
of the distribution of the median and IQR across contributing centres. Each of these graphs are
ordered (sorted) by a quantity being plotted, i.e. the median. Figure 4 (page 27) is an example of a
Median and IQR graph.
5. Scatter plots – The display for each contributing centre an estimate of interest which can be read
from the y-axis. Each scatter plot is ordered (sorted) by a quantity of interest. Figure 19 (page 43)
is an example of a scatter plot. Scatter plots over time display a quantity for a time point, i.e., NHS
year. When lines join the plotted points, these lines indicate a general trend. Figure 1 (page 9) is an
example of a Scatter plot over time.
Appendix tables with results for named centres;
On all tables that display results for contributing centres, the centres are ordered in alphabetical order
according to the centre’s name.
On tables that include equivalent results for previous NHS years, some centres have a result for an NHS
year before they first contributed as they submitted historic data for time periods before the first audit
year they contributed to, and some centres have contributed data to an audit year and not done so in
subsequent audit years.

Appendix I: Case Definitions
Eligible Cataract Surgery Criteria
• Operation performed between 1st April 2022 – 31st March 2023
• Operation performed in adults (aged 18 or above)
• Operation included a phacoemulsification procedure
• Operative data includes a surgeon identifier and valid surgeon grade
• Operation included a “cataract” indication for surgery (see the RCOphth NOD audit website
for details)
• Operation without any of the ineligible indications for surgery (see RCOphth NOD audit website
for details)
• Operation did not include certain operative procedures (see RCOphth NOD audit website
for details)
• Operations that included a pars plana vitrectomy with no vitreoretinal indication for surgery
and no other vitreoretinal procedures except for sponge and scissor vitrectomy or automated
anterior vitrectomy
• Operation not for a traumatic injury
• Operations in eyes with certain current or historic diagnosis (see RCOphth NOD audit website
for details).
• A minimum of 50 eligible cataract operations for each participated centre
For comparisons against previous NHS years, all the above apply except for the date period criteria
which is as follows;
• 2018 NHS year – 1st April 2018 – 31st March 2019
• 2019 NHS year – 1st April 2019 – 31st March 2020
• 2020 NHS year – 1st April 2020 – 31st March 2021
• 2021 NHS year – 1st April 2021 – 31st March 2022

2024/NOD/473

PCR – Posterior Capsule Rupture or Vitreous Prolapse or both
PCR was deemed to have occurred if any of the following intra-operative complications are recorded
during surgery; Zonule rupture – vitreous loss, PC rupture ± vitreous loss, Vitreous to the section at end
of surgery, Vitreous loss, Nuclear/ epinuclear fragment into vitreous, Intra-ocular lens (IOL) into the
vitreous, Lens fragments into vitreous, Lens matter in posterior segment, Nuclear matter in posterior
segment or if any of the following occurred.
• The operation includes any of ‘Sponge and scissors vitrectomy’, ‘Automated anterior vitrectomy’
or ‘Scleral fixed IOL’
• The operative procedure includes ‘Fragmatome lensectomy ± IOL’ with a previous or concurrent
phacoemulsification procedure*
• The operative procedure includes ‘Removal of lens fragments’ or ‘Removal of lens nucleus’
combined with a pars plana vitrectomy*
• If either of ‘Lens matter in posterior segment’, ‘Nuclear matter in posterior segment’, ‘Vitreous
to the section’ or ‘Vitreous in the anterior chamber’ were recorded within eight weeks of cataract
surgery, this includes the day of cataract surgery in the time frame. It is recognised that vitreous
egress is possible in rare cases, despite the absence of compromise of the capsule or zonules.
This still represents a complication of surgery, however EMR providers may offer a diagnosis
of post-operative complication that identifies such cases of vitreous in the anterior chamber
unrelated to intra-operative complication
• If there is a record of a dropped nucleus operation within 90 days of cataract surgery,
this includes the day of cataract surgery in the time frame
* For these cases, if there is a recorded intraoperative complication of PCR the case is eligible for
inclusion in the audit and allocated as PCR. If there is no recorded intraoperative complication
of PCR, the case is excluded from the audit under the assumption of previous cataract surgery.
Visual Acuity (VA)
Visual acuity measurements are reported using the LogMAR scale with numeric substitutions of 2.10,
2.40, 2.70 and 3.00 for the ability to count fingers (CF), the ability to distinguish hand movements (HM),
perception of light (PL) and no perception of light (NPL) respectively.
Preoperative VA was defined as the better of corrected distance visual acuity (CDVA) and uncorrected
distance visual acuity (UDVA) recorded within a six month ‘time window’ prior to surgery. Where there
are multiple occasions of measurement the VA measurement closest to the date of surgery is used
and measurements recorded on the same day as cataract surgery are considered as preoperative
measurements.
Postoperative VA was defined as the best measurement of CDVA or UDVA or pinhole visual acuity
(PHVA) within the ‘time window’ of between eight days and six months of cataract surgery (inclusive).
At least 50 eligible operations with VA data are required for a VA result to be produced. Postoperative
VA results were restricted to operations performed in the first 10 months of an NHS year to allow for
at least two months potential follow up. At least 50 eligible operations within the postoperative time
period are required for a result to be produced. For Vision Loss results, only centres with <40% missing
pre- and post-operative VA data were included.
52
2024/NOD/473

Vision Loss was defined as
• For eyes with a preoperative VA of <1.00 LogMAR, a loss of ≥0.30 LogMAR (doubling or worse
of the visual angle) between the preoperative and postoperative VA measurements
• For eyes with a preoperative VA of ≥1.00 LogMAR and 1.30 LogMAR.
Severe VA loss is defined as a loss of ≥0.60 LogMAR units from preoperative VA to postoperative VA,
and eyes with a preoperative VA of PL or NPL are not considered for severe VA loss estimates.
LogMAR VA is a continuous scale conversion for Snellen fractions that allows arithmetic calculations to
be employed in the analysis. Conversion between LogMAR and approximate Snellen scores, and their
interpretations, are as follows:

PCR
Posterior capsule rupture is a break in the posterior capsule of the lens as a
complication of cataract surgery. It may or may not be accompanied by vitreous
prolapse into the anterior chamber of the eye. For the purpose of the NOD Cataract
Audit, zonular dehiscence when accompanied by vitreousloss
is also termed PCR.
PHVA
Pin hole visual acuity – The pinhole is an eye shield with several small holes which allow
light rays to reach the retina without the interference of optical problems of the eye. It
is used to test visual acuity.

VA
Visual acuity is the sharpness of vision, measured by the ability to distinguish letters
or numbers at a given distance according to a fixed standard. We have reported VA
using the LogMAR scale (base 10 Log of the reciprocal of the visual angle). A normal
LogMAR VA is 0.0 and the number increases as vision gets worse. LogMAR=0.3 would
be at the boundary for driving a car and >1.3 would be at the level of registrable severe
sight impairment. A postoperative VA of 0.3 or better is often used as a measure of a
favourable outcome from surgery.

*The estimate of the proportion of cases submitted to the audit is derived from the number of completed cataract operations supplied to NHS digital or DHCW for the 2022 NHS
year. This estimation uses a pro-rata calculation for a centre’s denominator where the proportion of time during the NHS year that a centre had been recording cataract operations
was multiplied by the number of cataract operations supplied to NHS digital or DHCW. The numerator was the number of operations a centre supplied to the audit. Centre’s that
had more operations submitted to the national audit than in the NHS digital or DHCW data were all assumed to have a complete submission rate as the actual rate was not
possible to estimate. **These centres had no data in the NHS digital or DHCW data. ***These centres do not have to report to either NHS Digital or DHCW.

*The estimate of the proportion of cases submitted to the audit is derived from the number of completed cataract operations supplied to NHS Digital or DHCW for the NHS year. This estimation uses
a pro rata calculation for a centre’s denominator where the proportion of time during the NHS year that a centre had been recording cataract operations was multiplied by the number of cataract
operations supplied to NHS Digital or DHCW. The numerator was the number of operations a centre had supplied to the audit. Centres that had more operations submitted to the national audit
than in the NHS Digital or DHCW data were all assumed to have a complete submission rate as the actual rate was not possible to estimate. **These centres had no data in the NHS digital data.
***These centres do not have to report to either NHS Digital or DHCW. ****No estimate is produced for centres with <50 eligible operations in the postoperative qualifying time period.

*The estimate of the proportion of cases submitted to the audit is derived from the number of completed cataract operations supplied to NHS Digital or DHCW for the relevant NHS
year. This estimation uses a pro rata calculation for a centre’s denominator where the proportion of time during the NHS year that a centre had been recording cataract operations
was multiplied by the number of cataract operations supplied to NHS Digital or DHCW. The numerator was the number of operations a centre had supplied to the audit. Centres
that had more operations submitted to the national audit than in the NHS Digital or DHCW data were all assumed to have a complete submission rate as the actual rate was not
possible to estimate. For a full explanation of how case ascertainment was estimated see the Statistical Analysis Plan on the audit website. **These centres had no data in the
indicated NHS year NHS digital or DHCW data. ***These centres do not have to report to either NHS Digital or DHCW. ****These centres submitted data for <50 eligible operations
in the indicated NHS year.
