using a non-inferiority upper limit of 0.50. This 
sample size assumes a common standard deviation of 
0.98 and an expected difference of 0 for the 
difference in means between treatment groups using 
anterior chamber inflammation at Visit 4 
(Postoperative Day 7). The standard deviation is 
obtained by pooling the standard deviations of the LE 
and vehicle arms from the integrated adult studies of 
LE Gel in post cataract surgery8,9.  The absolute 
upper limit of the 95% CI for the treatment effect 
from the pooled data was 0.57.  From a clinical

Rationale 
perspective and based on this upper limit of 0.57, a 
non-inferiority margin of 0.50 is selected. The 0.50 
unit is < 0.57 and represents clinically one half of the 
smallest increment on the grading scale of anterior 
chamber inflammation. These sample size 
calculations utilize a one-sided, level alpha = 0.025 
non-inferiority analysis. Of the 124 subjects 
randomized, at least 62 subjects will be in the age 
group 0-3 years. As the percentage of subjects with 
rescue medication was 8% at Day 8 in one adult 
study (highest value), it is estimated that in children, 
12% can require rescue medication. Assuming a 
subject dropout rate of 12% for rescue medication, it 
is necessary to enroll 141 subjects. Furthermore, 
assuming a 10% rate for major protocol violations, 
158 subjects (79 per treatment group) will be 
randomized to obtain 124 PP subjects at the 
completion of the study.  
A sample size of 120 subjects (60 subjects per 
treatment group) yields 98% power to detect non-
inferiority of LE Ophthalmic Gel, 0.5% to 
Prednisolone Acetate Ophthalmic Suspension, 
1%. This sample size assumes a common standard 
deviation of 0.47, a two-sided alpha=0.05, a non-
inferiority margin of 0.35 and an expected 
difference of 0 for the difference in means between 
treatment groups using anterior chamber 
inflammation at Visit 5 (Postoperative Day 14).  
Assuming a subject dropout rate (including the 
initiation of rescue medication) of 12%, 
approximately 140 subjects will be randomized of

the primary outcome of the study.  Analyses on the 
PP set will be used for the primary efficacy analysis 
and will be performed for the primary and secondary 
efficacy endpoints, Analysis using the PP 
population will be used to supplement the ITT 
analysis, analyzing subjects according to the 
treatment received.”

Description of Change or Clarification 
Rationale 
7.6.1 Methods of 
Analysis 
39-40 
Updated the description of primary efficacy analysis as 
follows: 
“The primary efficacy analysis will be based on the 
Per Protocol (PP) set ITT population with missing 
data imputed using the last observation carried 
forward (LOCF) method and the primary endpoint 
mean grade of anterior chamber inflammation at Visit 
4 Visit 5 (Postoperative Day 7 14). The mean grade 
of anterior chamber inflammation at Visit 4 Visit 5 
(Postoperative Day 7 14) will be analyzed using an 
analysis of variance (ANOVA) model with treatment 
as a classification variable. 
…The null hypothesis will be rejected and non-
inferiority established if the upper limit of the 
confidence interval does not exceed 0.50 0.35. 
To supplement the primary analyses, the analyses 
above will be repeated for the PP population; no 
imputation will be conducted for missing data. 
Any discrepancy between the ITT and PP analyses 
will be explained. 
The last observation carried forward (LOCF) 
imputation method implements the idea that a 
subject’s anterior chamber inflammation is 
unchanged after dropout, an assumption that needs to 
be checked for plausibility. To this end, a sensitivity 
analysis of the primary endpoint using the ITT set 
will be performed. 
The secondary efficacy analyses will be conducted 
based on include all subjects in the ITT population 
as well as and the PP sets population. 
As a secondary analysis, the analysis of the mean 
grade of anterior chamber inflammation will be 
repeated as above for Visits 54 and 6 (Postoperative 
Days 147 and 298, respectively).” 
Changed to align with 
FDA Written Request, 
changed to follow 
FDA Draft Guidance 
for Industry, Non-
Inferiority Clinical 
Trials (March 2010), 
and clarification. 
 
7.6.3 Subject 
Disposition 
40-41 
Updated descriptions of study populations as follows: 
“• 
subjects randomized (ITT set population) 
• 
subjects treated (Safety set population) 
• 
subjects in the PP set population” 
Clarification. 
7.6.7 Missing Data 41 
Updated missing data description as follows: 
“Subjects with missing data or with rescue 
medication prior to Day 7 will be excluded from the 
primary PP analysis. For the primary efficacy 
endpoint analyzed using the ITT set population, 
missing data and data from subjects placed on rescue 
medication will be analyzed imputed using the 
LOCF methodology. For the secondary efficacy 
endpoints analyzed using the ITT set, missing data 
and data from subjects placed on rescue medication 
prior to the visit being summarized will be imputed 
as LOCF and will also be summarized as missing. 
For the PP analysis, missing data and data from 
subjects placed on rescue medication will not be 
imputed.” 
Clarification and 
changed to align with 
change in primary 
efficacy endpoint.

SYNOPSIS 
Bausch + Lomb Study #670 
Title: 
A Randomized, Multicenter, Double Masked, Parallel-Group Study 
Assessing the Safety and Efficacy of Loteprednol Etabonate Ophthalmic 
Gel, 0.5% versus Prednisolone Acetate Ophthalmic Suspension, 1% for the 
Treatment of Intraocular Inflammation Following Surgery for Childhood 
Cataract 
Phase of study: 
Phase 4 
Number of study 
centers and subjects: 
Approximately 140 subjects at approximately 30 investigative sites in the 
United States (US), European Union (EU), and Asia Pacific (AP) will be 
enrolled in this study. 
Planned study period: 
Study duration will be approximately 11-19 weeks depending on the time 
between screening, the day of surgery, and the last study visit (Visit 8, 
Postoperative Day 90). The enrollment period is expected to be completed in 24 
months. 
Objective(s): 
The primary objective is to compare the efficacy and safety of Loteprednol 
Etabonate (LE) Ophthalmic Gel, 0.5% to Prednisolone Acetate Ophthalmic 
Suspension, 1% for the treatment of postoperative inflammation following 
ocular surgery for childhood cataract. 
Study design: 
Approximately 140 subjects will be enrolled in this double-masked, parallel-
group, active-controlled study at approximately 30 investigative sites in the 
United States (US), European Union (EU), and Asia Pacific (AP).  
A total of 140 subjects aged 0-11 years will be randomized in a 1:1 ratio to LE 
Ophthalmic Gel, 0.5% or Prednisolone Acetate Ophthalmic Suspension, 1%. Of 
the 140 randomized subjects, at least 60 subjects (approximately 30 subjects per 
treatment group) will be in the age range from 0-3 years. Prednisolone Acetate 
Ophthalmic Suspension, 1% was chosen as the active-control because it has a 
long history as the standard of care in the US. 
Study duration will be approximately 11-19 weeks from screening to the last 
visit (Visit 8, Postoperative Day 90). Subjects will visit the clinic eight times. 
Visit 1 will be the Screening Visit and will occur up to a maximum of 29 days 
prior to surgery. Visit 2 will be on the day of surgery. At the end of surgery on 
Visit 2, eligibility for randomization into the study will be assessed and, if 
appropriate, subjects will be randomized at this time. Randomized subjects will 
complete postoperative study Visits 3 through 8 (Postoperative Days 1, 7, 14, 
28, 42, and 90, respectively). 
Subject’s eyes meeting eligibility criteria at both Visit 1 (Screening) and Visit 2 
(Surgery/Randomization) will be randomized to receive study medication. If 
both eyes of a subject undergo routine, uncomplicated surgery at Visit 2 
(Surgery/Randomization) and meet eligibility criteria, the subject’s right eye 
will be considered the study eye. In the event that the subject requires surgery 
on the contralateral eye at any time during the study, the fellow eye will be 
treated with standard of care medication. 
The subject will receive the first dose of study drug by the unmasked designee 
at the end of the surgery. Either the unmasked designee or the subject’s 
parent/legal guardian will then administer 1 t o 2 drops of study drug to the 
lower cul-de-sac of the study eye once in the evening on the day of surgery and 
then four times a day (QID), at approximately four hour intervals, beginning on 
the morning after surgery. QID dosing will continue until postoperative day 14, 
including dosing at appropriate time intervals on the day of a visit. Treatment 
will be tapered from QID to twice a d ay (BID) during the interval between 
postoperative days 15 and 21. Treatment will be further tapered from 
postoperative day 22 until day 28 to once a day (QD) with the last dose being 

Study #670 - Protocol 
Amendment 6, 22 May 2013

administered on the day prior to Visit 6 (Postoperative Day 28). 
Criteria for inclusion: 
This study will include subjects who meet the following criteria at Visit 1 
(Screening): 
1. Subjects who are male or female, 0 to 11 years of age, on the date the 
Informed Consent Form (ICF) is signed.  
2. Subjects who have the ability to understand and provide assent (when 
applicable) and whose parent/legally authorized representative has the 
ability to understand and provide written informed consent on the 
Institutional Review Board (IRB)/Ethics Committee (EC) approved ICF 
and provide authorization as appropriate for local privacy regulations.

Summaries for continuous variables will include the sample size, mean, 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 16 
standard deviation (SD), median, minimum, and maximum. Summaries for 
discrete variables will include the tabulation of frequencies and percentages. 
Means and medians will be presented to one more decimal place than the 
recorded data. Standard deviations will be presented to two more decimal 
places than the recorded data. Minimum and maximum values will be presented 
using the same number of decimal places as the recorded data. Confidence 
intervals (CIs) will be presented using the same number of decimal places as the 
parameters (eg, mean). Percentages will be presented to one decimal place.  
 
Sample Size 
A sample size of 120 s ubjects (60 subjects per treatment group) yields 98% 
power to detect non-inferiority of LE Ophthalmic Gel, 0.5% to Prednisolone 
Acetate Ophthalmic Suspension, 1%. This sample size assumes a co mmon 
standard deviation of 0.47, a two-sided alpha=0.05, a non-inferiority margin of 
0.35 and an expected difference of 0 for the difference in means between 
treatment groups using anterior chamber inflammation at Visit 5 (Postoperative 
Day 14).  Assuming a subject dropout rate (including the initiation of rescue 
medication) of 12%, approximately 140 subjects will be randomized of which 
at least 60 subjects will be in the age group 0-3 years as per the FDA’s Written 
Request. 
 
Hypothesis 
Test for the non-inferiority of LE Ophthalmic Gel, 0.5% to Prednisolone 
Acetate Ophthalmic Suspension, 1% will be primarily based on the following 
one-sided null hypothesis (Ho) and alternative hypothesis (Ha): 
 
Ho: µLE - µPR ≥ 0.35     versus              Ha: µLE -  µPR < 0.35 
where µLE and µPR are the mean grade of anterior chamber inflammation at 
Visit 4 (Postoperative Day 7) for LE Ophthalmic Gel, 0.5% and Prednisolone 
Acetate Ophthalmic Suspension, 1% treatment group, respectively. 
 
Primary Analysis 
For the primary efficacy analysis, the mean grade of anterior chamber 
inflammation at Visit 5 (Postoperative Day 14) will be calculated by treatment 
group, including a two-sided 95% CI about the difference between the means. If 
the upper limit of the 95% CI is less than 0.35, then non-inferiority of LE 
Ophthalmic Gel, 0.5% to Prednisolone Acetate Ophthalmic Suspension, 1% 
will be claimed.  
The primary efficacy analysis will be based on the ITT population. The primary 
analysis will be repeated using the PP population to supplement the ITT 
analysis. Any discrepancy between the 2 analyses will be explained. 
 
Secondary Efficacy Analysis 
The secondary efficacy analyses will be conducted based on the ITT population 
as well as the PP population. 
As a secondary analysis, the analysis of the mean grade of anterior chamber 
inflammation will be repeated as above for Visits 4 and 6 (Postoperative Days 7 
and 28, respectively). 
Additional secondary analyses include:  
• 
the proportion of subjects with  a nterior chamber inflammation with 
Grade 0, Grade 1, Grade 2, Grade 3, and Grade 4 for each visit 
(Postoperative Days 7, 14, and 28) 
• 
the proportion of subjects with presence/absence and total area, if present, 
of synechiae for each visit (Postoperative Days 7, 14, and 28) 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 17 
• 
the proportion of subjects with presence/absence and total number, if 
present, of precipitates on the implant and cornea at each visit 
(Postoperative Days 7, 14, and 28) 
For each of the above endpoints, treatment groups will be compared using the 
Pearson Chi-squared test or fisher’s exact test as appropriate. Differences 
between the proportions of treatment groups and 95% confidence interval about 
the differences will be presented. 
Subgroup analyses will be performed for anterior chamber inflammation, 
anterior chamber cells, and anterior chamber flare as appropriate by method of 
assessment (slit lamp versus penlight with handheld magnifying 20 diopter 
lens), country (region), age group, IOL implantation, and iris color. 
 
Safety Analysis 
All subjects in the safety set will be included in the safety analyses. Intraocular 
pressure will be summarized by visit using continuous summaries (including 
change from baseline and change from screening) for the following items: 
• 
change in IOP from baseline to each visit 
• 
greatest IOP change from baseline - including the one day postoperative 
measurement at Day 1 
• 
greatest IOP change from baseline - excluding the one day postoperative 
measurement at Day 1 
• 
ocular signs (biomicroscopic examination of the lids, conjunctiva, cornea, 
anterior chamber without pupil dilation) 
Treatment emergent systemic AEs will be summarized using discrete 
summaries at the subject and event level by system organ class and preferred 
term for each treatment group. Treatment emergent ocular AEs will be 
summarized for treated eyes and fellow eyes separately. Similarly, treatment 
emergent AEs will be summarized by severity and relationship separately. All 
AEs will be coded using a Med DRA dictionary (the most current version 
available at the start of the study will be used). 
 
Tolerability 
Ocular symptoms will be summarized using discrete summary statistics by visit 
and treatment group. These data will be summarized under the safety analyses.

INTRODUCTION  
Corticosteroids are potent, non-specific, anti-inflammatory drugs that inhibit a variety of 
chemotactic substances and factors that mediate capillary permeability, contraction of 
nonvascular smooth muscle, and vasodilation. In addition, corticosteroids suppress 
inflammation by inhibiting edema, fibrin deposition, migration of leukocytes, and 
phagocytic activity. 
Topical corticosteroids are useful in a variety of ophthalmic conditions and are generally 
indicated for treatment of steroid-responsive inflammatory conditions of the palpebral 
and bulbar conjunctiva, cornea, and anterior segment of the eye.1 Although 
corticosteroids are widely used as a topical agent for ocular inflammation, most possess a 
safety risk profile that limits their general utility. A common risk associated with 
corticosteroid therapy is an elevation of intraocular pressure (IOP).2,3 In addition, chronic 
use of topical corticosteroids may result in the development of cataracts.4 
Loteprednol etabonate (LE) is a novel compound designed as a unique C-20 ester 
corticosteroid5 that will undergo a predictable transformation to an inactive metabolite. 
The relatively rapid metabolism of LE to an inactive metabolite improves the safety 
profile of this corticosteroid. In clinical studies, LE Ophthalmic Suspension, 0.5% 
(Lotemax®) has been shown to have a decreased incidence of clinically significant IOP 
increase (ie, ≥10 mm Hg) compared to prednisolone acetate.6,7 This characteristic of LE 
makes it an optimal candidate for use in inflammatory ocular conditions.  
The pH of LE Ophthalmic Gel, 0.5% was adjusted to 6.0 - 6.5 making it closer to normal 
physiological pH of 7.4. Preservative effectiveness has been demonstrated in this new 
formulation using a reduced level of the preservative, benzalkonium chloride (BAK), 
than in the currently marketed product (ie, from 100ppm or 0.01% to 30 ppm or 0.003%), 
which may improve the tolerability of the gel.

OBJECTIVE 
The primary objective is to compare the efficacy and safety of Loteprednol Etabonate 
(LE) Ophthalmic Gel, 0.5% to Prednisolone Acetate Ophthalmic Suspension, 1% for the 
treatment of postoperative inflammation following ocular surgery for childhood cataract.

STUDY DESIGN 
3.1 
Description of Study Design Including Choice of Control Groups  
Approximately 140 subjects will be enrolled in this double-masked, parallel-group, 
active-controlled study at approximately 30 investigative sites in the United States (US), 
European Union (EU), and Asia Pacific (AP).  
A total of 140 subjects aged 0-11 years will be randomized in a 1:1 ratio to LE 
Ophthalmic Gel, 0.5% or Prednisolone Acetate Ophthalmic Suspension, 1%. Of the 140 
randomized subjects, at least 60 subjects (approximately 30 subjects per treatment group) 
will be in the age range from 0-3 years. Prednisolone Acetate Ophthalmic Suspension, 
1% was chosen as the active-control because it has a long history as the standard of care 
in the US. 
Study duration will be approximately 11-19 weeks from screening to the last visit (Visit 8, 
Postoperative Day 90). Subjects will visit the clinic eight times. Visit 1 will be the 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 19 
Screening Visit and will occur up to a maximum of 29 days prior to surgery. Visit 2 will 
be on the day of surgery. At the end of surgery on Visit 2, eligibility for randomization 
into the study will be assessed and, if appropriate, subjects will be randomized at this 
time. Randomized subjects will complete postoperative study Visits 3 t hrough 8 
(Postoperative Days 1, 7, 14, 28, 42, and 90, respectively). 
Subject’s eyes meeting eligibility criteria at both Visit 1 (Screening) and Visit 2 
(Surgery/Randomization) will be randomized to receive study medication. If both eyes of 
a subject undergo routine, uncomplicated surgery at Visit 2 (Surgery/Randomization) and 
meet eligibility criteria, the subject’s right eye will be considered the study eye. In the 
event that the subject requires surgery on the contralateral eye at any time during the 
study, the fellow eye will be treated at the Investigator’s discretion with standard of care 
medication. 
The subject will receive the first dose of study drug by the unmasked designee at the end 
of the surgery. Either the unmasked designee or the subject’s parent/legal guardian will 
then administer 1 to 2 drops of study drug to the lower cul-de-sac of the study eye once in 
the evening on the day of surgery and then four times a day (QID), at approximately four 
hour intervals, beginning on the morning after surgery. QID dosing will continue until 
postoperative day 14, including dosing at appropriate time intervals on the day of a visit. 
Treatment will be tapered from QID to twice a day (BID) during the interval between 
postoperative days 15 and 21. Treatment will be further tapered from postoperative day 
22 until day 28 to once a day (QD) with the last dose being administered on the day prior 
to Visit 6 (Postoperative Day 28).

2. Subjects with glaucoma, ocular hypertension, or those receiving intraocular pressure 
(IOP) lowering therapy in either eye or systemically. 
3. Subjects with a history of steroid-induced IOP elevation in either eye. 
4. Subjects who have suspected permanent low vision or blindness (eg, legal definition 
of blindness: visual acuity [VA] of ≤ 20/200 or visual field of ≤ 20 degrees) in the 
fellow non-study eye. (The study eye must not be the subject's only sighted eye.) 
5. Subjects who have had ocular surgery (including laser therapy) in the study eye 
within 90 days prior to randomization on Visit 2 (Surgery/Randomization). 
6. Subjects who are expected to require treatment with systemic or ocular (study eye) 
corticosteroids other than study drug during the 90 days following cataract surgery or 
have used any systemic or ocular corticosteroids (study eye) within 14 days prior to 
cataract surgery. (Ocular therapy with corticosteroids in the fellow eye is permitted.)

14. Subjects who were previously randomized in this study. 
3.2.2 
Subject Completion 
The subject has completed the study when Visit 8 ( Postoperative Day 90) has been 
completed and the subject has been exited. Subjects who require further follow-up for an 
AE will be followed according to Section 6.3 and 6.4. 
3.2.3 
Rescue Therapy 
Subjects will be assessed at Visits 3 through 6 (Postoperative Days 1, 7, 14, and 28) for 
rescue. A study eye with greater than anticipated inflammation at Visit 3 or, at the 
following visits, a worsening or no change of the grade of inflammation compared to the 
previous visit may be eligible for rescue therapy. In some cases a persistent or worsening 
inflammation may be due to a lack of compliance. This should be explored and rectified. 
If the Investigator deems rescue necessary, the choice of rescue therapy and dosing shall 
be determined by the Investigator. Subjects requiring rescue therapy for inflammation 
will stop treatment with study medication. The subject should be exited from the study 
and the reason selected for exit should be “rescue therapy” in the eCRF. This should not 
be reported as an AE unless determined to be an SAE.  
3.2.4 
Subject Discontinuation 
A subject MAY be discontinued (at the discretion of the Investigator, the Sponsor and/or 
the IRB/EC) prior to the final study visit for several reasons, including, but not limited to:  
• 
a serious adverse event (SAE) occurring during the course of the study, which 
precludes continued treatment or follow-up  
• 
the subject’s parent/legally authorized representative not following required study 
procedures 
A subject MUST be discontinued prior to the final study visit for any of the following 
reasons: 
• 
voluntary withdrawal 
• 
onset of menarche during the study 
• 
death 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 22 
• 
Investigator decision that it is  not in the best medical interest of the subject to 
continue participation in the investigation 
• 
requires rescue medication 
Prior to discontinuing a subject, every effort should be made to contact the subject’s 
parent/legal guardian, schedule a final study visit, and obtain as much follow-up data as 
possible, and to retrieve all study materials. Adverse events will be followed as described 
in Section 6.3 and 6.4. Subject withdrawals will be documented clearly on t he source 
document and applicable electronic case report form (eCRF). The assessments scheduled 
for Visit 8 (Postoperative Day 90) should be performed at this early termination visit. 
Subject discontinuation will be documented clearly on the applicable eCRF. Any subject 
discontinued from the study after randomization will not be replaced. 
3.2.5 
Lost to Follow-up 
Subjects who do not return for scheduled follow-up Visits 3 through 8, as defined by the 
visit window and cannot be contacted via two telephone calls and one letter with delivery 
confirmation are considered lost to follow-up. All follow-up attempts will be documented 
and kept with the subject’s source documentation, and the applicable eCRFs will be 
completed. 
3.3 
Investigators 
The study will be conducted at approximately 30 investigative sites located in the US, EU, 
and AP.  
The study will be conducted by Investigators who are determined by Bausch + Lomb to 
be suitably qualified by training and experience to conduct this study in compliance with 
all applicable GCPs and all applicable regulatory requirements. Sub-Investigators will be 
identified on t he FDA Form 1572 a nd in the regulatory documents required by the 
country in which the study is being conducted. 
Each Investigator will enroll approximately 5 subjects. In the event that selected sites do 
not meet full enrollment, the Sponsor may decide to increase enrollment as needed at 
other currently active sites and additional site(s) may be added to satisfy the enrollment 
requirements of the study.  
3.4 
Study Duration 
Study duration will be approximately 11-19 weeks depending on the time between 
screening, the day of surgery, and the last study visit (Visit 8, Postoperative Day 90). The 
enrollment period is expected to be completed in 24 months. 
Eligible subjects who are enrolled in the study will be seen for eight scheduled study 
visits. Visit 1 will be the Screening Visit and will occur up to a maximum of 29 days 
prior to surgery. Visit 2 will be on the day of surgery. At the end of surgery on Visit 2, 
eligibility for randomization into the study will be assessed and, if appropriate, subjects 
will be randomized at this time. Randomized subjects will complete postoperative study 
Visits 3 through 8 (Postoperative Days 1, 7, 14, 28, 42, and 90, respectively).

Treatments 
A total of 140 subjects will be randomly assigned in a 1:1 ratio to receive either LE 
Ophthalmic Gel, 0.5% or Prednisolone Acetate Ophthalmic Suspension, 1%. 
4.0 
STUDY MATERIALS 
4.1 
Description of Test Article  
Loteprednol Etabonate Ophthalmic Gel, 0.5%, contains the active ingredient loteprednol 
etabonate 0.5% and the preservative benzalkonium chloride (BAK), 0.003%. It also 
contains the inactive ingredients glycerin, propylene glycol, sodium chloride, 
polycarbophil, sodium hydroxide, tyloxapol, edetate disodium dihydrate, boric acid, and 
water for injection. 
4.2 
Description of Comparator  
Prednisolone Acetate Ophthalmic Suspension, 1% contains the active ingredient 
prednisolone acetate 1% and the preservative BAK 0.004%. The inactive ingredients are 
comprised of: boric acid; edetate disodium; hypromellose; polysorbate 80; purified water; 
sodium bisulfite; sodium chloride; and sodium citrate. The pH during its shelf life ranges 
from 5.0 - 6.0. 
4.3 
Instructions for Use and Administration  
Following the initial drop administration by the unmasked study personnel at the end of 
the surgery, either the unmasked designee or the subject’s parent/legal guardian will 
administer 1 to 2 drops of study drug into the study eye once in the evening on the day of 
surgery and then QID, at approximately four hour intervals, beginning on the morning 
after surgery. QID dosing will continue until postoperative day 14. Treatment will be 
tapered from QID to BID during the interval between postoperative days 15 a nd 21. 
Treatment will be further tapered from postoperative day 22 until day 28 to QD with the 
last dose being administered on the day prior to Visit 6 (Postoperative Day 28).  
Parents/legal guardians will be trained with regard to the instillation of eye drops prior to 
administration of the initial dose. 
Site personnel will instruct the subject’s parent/legal guardian on the proper instillation of 
their study medication without using the study drug. 
Subject’s parent/legal guardian will be instructed to return the study drug at  
Visits 4, 5 a nd 6 for weighing, and for collection in the original packaging at Visit 6 or 
early study discontinuation. Both the Investigator and the subjects will be masked to the 
study drug assignment. 
4.3.1 
Storage Requirements 
All clinical trial material will be stored in an area free of environmental extremes, 
avoiding excessive heat. Clinical trial material should be stored upright at 15-25°C  
(59-77°F). A daily temperature log will be maintained at the site. The storage location at 
the clinical sites will have limited access.  
Subject’s parent/legal guardian must be instructed regarding proper storage. 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 24 
4.4 
Other Materials  
Additional materials (eg, scales) will be provided by the Sponsor, depending on the 
requirements by the site.  
4.5 
Packaging and Labeling  
The test and control articles will be packaged and labeled in a manner consistent with the 
study design. All investigational products will be labeled and supplied by the Sponsor. 
The test article will be manufactured and filled (5-mL) into 10-mL, white, low density 
polyethylene (LDPE) bottles with pink polypropylene caps by Bausch & Lomb 
Incorporated (Tampa, FL). The control article, Prednisolone Acetate Ophthalmic 
Suspension, 1%, will be sourced from readily available commercial supply. The control 
article will be provided in 10-mL industry standard ophthalmic bottles.  
The investigational products will be packaged and labeled in a manner consistent with the 
study design. Investigational products will be provided in kit boxes (one study kit per 
subject) each with two dropper bottles containing sufficient doses for duration of 
treatment. Supply labeling will minimally include the protocol number, kit identification 
number, product description, directions for use, storage conditions, caution statement, 
and Sponsor information. Labeling for European sites will follow the requirements of the 
EU Directive 2001/20/EC (Annex 13). 
Subject kit boxes and subject-specific reserve kit boxes will be labeled with a 2 -part,  
tear-off masked label. The left part of the label will remain affixed to the subject kit. 
Upon dispensing, the right portion of the label, which contains hidden drug information, 
will be detached and placed in the subject’s source document. 
Subject supplies will be labeled according to a co mputer-generated randomization 
scheme. The medication will be identified as a new drug, limited by federal law,   
EU Directive, and AP local regulation to investigational use, and appropriately labeled 
for investigational use for this age group. 
4.6 
Accountability 
The Investigator or designee will be responsible for keeping current and accurate records 
of the amount of study drug received and dispensed, and its disposition. The study drug 
must be stored under the appropriate conditions in a secure area and are to be dispensed 
only to subjects enrolled in the study, in accordance with the conditions specified in this 
protocol. In order to assess compliance of administration, subject’s parent/legal guardian 
will be instructed to record the date and time of each study drug administration on a diary 
provided by the Sponsor. Site personnel will dispense diaries and the unmasked designee 
will weigh study drug (each bottle) before dispensing at Visit 2. Subjects should bring 
their study diaries and study drug (both bottles) to Visits 3 through 6. Site personnel will 
review the diaries and the unmasked designee will weigh the study drug (each bottle) at 
Visits 3 through 6 to assess compliance. 
During the course of the study, the Investigator’s unmasked designee must maintain an 
inventory of all study drug, dispensed to or returned by the subject, including subject 
identifiers. 
At time points throughout the study and/or upon c ompletion of the study, the 
Sponsor/Sponsor's representative will review and verify the Investigator's accountability 

Study #670 - Protocol 
Amendment 6, 22 May 2013

records. Following verification, and as directed by the Sponsor, all used, unused and 
returned product must be returned to the Sponsor at the address provided on t he 
Personnel and Facilities page, or with the Sponsor's permission, disposed of at the site in 
an appropriate manner. 
4.7 
Masking/Unmasking  
The Investigator, subject/subject’s parent/legal guardian, and Sponsor personnel involved 
in the monitoring or conduct of the study will be masked to the study drug. The 
randomization list will be produced prior to study enrollment by an unmasked statistician 
not otherwise involved in the study. Although the test and active comparator bottles will 
be visibly different, attempts will be made to mask the subjects by removing commercial 
labeling, replacing with identical investigational labels, and packaging in identical kit 
boxes. An unmasked designee will be able to view both test and comparator bottles as 
part of their study activities and are therefore considered as unmasked although the 
designee will not have access to the randomization code. The unmasked designee will be 
responsible for instilling the first drop after surgery, and dispensing, weighing and 
collecting the test articles. The unmasked designee will not be responsible for any study 
assessments for this study. Site Monitors will be able to monitor subject diaries and 
accountability records but will not be able to reconcile the bottles in the boxes with the 
accountability records. 
The Investigator must contact the Medical Monitor prior to unmasking of study treatment. 
In an emergency situation, however, where knowledge of the study treatment is critical to 
subject safety, the code may be broken. If unmasking is necessary, the masked section of 
the two-part label, which is placed in the subject’s source documentation, can be 
scratched off to reveal the treatment assignment for that subject. 
The Investigator must notify the Medical Monitor and/or Study Manager as soon as 
possible after unmasking. In addition, the Investigator must record the date, time, and 
reason for unmasking the study treatment in the source documentation. 
4.8 
Methods of Assigning Subjects to Treatment Groups 
4.8.1 
Treatment Allocation 
Study drug will be allocated to eligible subjects at Visit 2, which will be the day the 
subject has undergone routine, uncomplicated surgery for childhood cataract. Each 
enrolled subject will receive sufficient study drug for the duration of treatment  
(ie, two bottles). The unmasked designee will dispense the next sequential kit number and 
administer the first dose after surgery.  
4.8.2 
Treatment Replacement 
Reserve supplies of each subject’s study drug (ie, one bottle) will be provided to the 
Investigators, to be dispensed only if the original subject kit is lost, damaged, or 
consumed prior to the end of treatment. 
4.9 
Risk Assessment 
Refer to the Investigator’s Brochure provided by the Sponsor which includes a summary 
of data and guidance for the Investigator in regards to the clinical pharmacology and 
safety profile of LE. 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 26 
The subject’s parent/legal guardian will be informed of any risks in the ICF. 
4.10 
Selection of Dose 
The dose regimen in this study is the same regimen across both treatment groups  
(ie, 1 to 2 drops of study drug instilled in the study eye, QID, at approximately 4 hour 
intervals). This regimen was selected for the study based on the dose regimen of the 
currently marketed Lotemax (LE Ophthalmic Gel, 0.5%) and is also the treatment 
recommended in the Package Insert (PI) and Summary of Product Characteristics (SmPC) 
of the comparator drug.  
Based on the standard of care for the treatment of postoperative inflammation in the US, 
both treatment groups will be dosed QID for the first 14 days and then tapered to BID 
from postoperative days 15 through 21 and the further tapered to QD from postoperative 
day 22 until the day prior to Visit 6 (Postoperative Day 28).

STUDY METHODS 
5.1 
Study Visits  
Refer to Appendix A for a schedule of visits and parameters and Appendix B for methods 
of clinical evaluation.  
Following identification of a potential subject, the Investigator (or designee) will explain 
the purpose of the study, procedures, risks/benefits, and subject responsibilities to the 
potential subject’s parent/legal guardian. The subject’s/subject’s parent/legal guardian 
willingness and ability to meet the follow-up requirements of the study will be 
determined. If the subject’s parent/legal guardian chooses to participate in the 
investigation, then the subject’s assent (when applicable and according to local 
regulations) and written informed consent will be obtained. The subject’s parent/legal 
guardian and the person obtaining written consent will sign and date the IRB/EC-
approved ICF. The original signed document will be retained in the subject records, and a 
copy will be provided to the subject’s parent/legal guardian. In addition, the applicable 
privacy regulation requirements must be met.

5.1.9 
Unscheduled Visits 
Additional visits may be scheduled, as necessary, to ensure the safety and well-being of 
subjects. All additional exams should be fully documented in the source documents and 
on Unscheduled Visit eCRFs, as appropriate. Visits intended to fulfill scheduled visit 
requirements that fall outside the designated scheduled visit range, are not Unscheduled 
Visits. In these cases, the visit data will be collected and transcribed to the appropriate 
scheduled visit eCRF. 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 31 
If a subject is seen for multiple visits during a given visit timeframe, the data from the 
visit that is intended to meet the protocol requirements for the scheduled visit should be 
captured on the visit eCRF. Where such a determination cannot be made, the first visit 
within the scheduled visit interval will be used for completion of the protocol required 
scheduled visit eCRF. Data from any additional visits within a scheduled visit interval 
will be captured on an Unscheduled Visit eCRF. 
5.1.10 
Missed Visits  
If a subject misses any scheduled follow-up visit and cannot be seen prior to the start of 
the visit range for the next scheduled follow-up visit, the visit is considered missed. 
5.2 
Post-study Follow-up  
If a subject requires further follow-up of AEs upon discontinuation or completion of the 
study, the Investigator must schedule post-study follow-up visits, as necessary.  
Refer to Sections 6.3 and 6.4 for follow-up of AEs following study exit. 
5.3 
Study Completion  
Depending on local regulations, Bausch + Lomb Global Clinical Operations will notify 
the Investigator when to contact the IRB/EC to inform them that the study is complete or 
Bausch + Lomb will do this on the behalf of the Investigator. In the EU, Bausch + Lomb 
will inform the regulatory agencies in the concerned member states in addition. 
5.3.1 
Early Study Termination 
If during the study it becomes evident to the Sponsor that the study should be stopped 
prematurely or placed on hol d, appropriate notification will be given to the 
Investigator(s), IRB/EC, FDA, and appropriate EU regulatory agencies, as applicable. 
Bausch + Lomb Global Clinical Operations will instruct the Investigators to stop/restart 
dispensing study materials and will arrange for study closeout, if applicable, at each site. 
5.4 
Concomitant Medications/Therapy  
Administration of all medications used by the subject, the breastfeeding mother, or wet 
nurse up to 30 days prior to study entry (date ICF signed) through study exit must be 
recorded in the source documentation and in the Concomitant Medications eCRF. 
Indications for these medications should be recorded in the subject's Medical History 
eCRF, as applicable. 
5.4.1 
Permitted Therapy  
Permitted therapy applies to the subject, breastfeeding mother, or wet nurse. Use of 
topical antibiotics is allowed if they are not used in combination with any steroid in the 
study eye (eg, Zylet® or TobraDex should not be used). Topical antibiotics used 
preoperatively and postoperatively are allowed bilaterally and must be recorded in the 
Concomitant Medications eCRF provided by the Sponsor. Intraoperative use of topical 
antibiotics or other standard of care surgical medications should be recorded in the source 
documentation only. 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 32 
In the event that the subject requires surgery on the contralateral eye at any time during 
the study, the fellow eye will be treated at the Investigator’s discretion with standard of 
care medication.  The standard of care medication must be recorded under concomitant 
medications in the eCRF provided by the sponsor.  
With the exception of the disallowed medications in Section 5.4.2, any medications that, 
in the Investigator’s judgment, will not interfere with the study parameters are allowed to 
be used concurrently by the subject, breastfeeding mother, or wet nurse; for example, the 
following medications are permitted: 
• 
systemic analgesics (eg, 
acetaminophen/paracetamol) 
• 
systemic antimicrobials 
• 
oral birth control pills 
• 
antidepressants 
• 
≤100 mg/day acetylsalicylic acid (for 
breastfeeding mother/wet nurse only) 
• 
thyroid preparations 
• 
hypoglycemic agents 
• 
antihypertensive agents 
• 
anticholesterol medications 
• 
cardiovascular agents 
• 
insulin 
 
− 
Standard anesthetic and mydriatic agents may be used intraoperatively or for 
postoperative diagnostic purposes (ie, IOP and funduscopy). Ocular NSAIDs may 
not be used for mydriasis or at any other time point during the study in the study 
eye. Ocular therapy with NSAIDs and/or corticosteroids in the fellow eye is 
permitted. 
− 
The long term use of systemic NSAIDs is not allowed during the study. If 
unavoidable, use of systemic NSAIDs can be permitted only after Visit 5, but 
should be kept to a minimum and treatment duration with NSAIDs should be kept 
short (for example, one day per treatment period). 
− 
Topical ocular hypotensive agents, if used at the end of surgery by the study site, 
will be used with ALL subjects treated at that site.  
− 
Intracameral injection of antibiotic is allowed at the end of surgery. 
5.4.2 
Disallowed Therapy 
A disallowed medication could be administered in an emergency if the subject’s safety 
was in jeopardy. The Investigator must notify the Medical Monitor as soon as possible 
after administering a disallowed medication to verify if the subject can continue in the 
study. If a subject has taken any disallowed medication, this should be recorded as a 
protocol deviation. Disallowed therapy that is used for persistent or worsening 
inflammation, however, is called “Rescue Therapy” and is discussed in detail in  
Section 3.2.3.  
Disallowed medications include the following: 
• 
Ocular (study eye): 
− 
corticosteroids 
− 
NSAIDs  
− 
topical antibiotic-steroid combination products (eg, Zylet, TobraDex, etc) 
• 
Ocular (study and fellow eye): 
− 
mast cell stabilizers 
− 
antihistamines 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 33 
− 
decongestants  
− 
immunosuppressants (eg, Restasis) 
• 
Systemic (subject, breastfeeding mother, or wet nurse): 
− 
corticosteroids (except corticosteroid inhalers and dermatological corticosteroids, 
as long as they are not used on the eyelids or surrounding area) 
− 
NSAIDs (short term use of systemic NSAIDs is permitted only after Visit 5.  
Please refer to section 5.4.1 for details) 
− 
immunosuppressants  
• 
Any medication that the Investigator feels may interfere with study parameters 
5.5 
Treatment Compliance  
Any subject/subject’s parent/legal guardian who does not follow instructions to a degree 
that, in the Sponsor or Investigator’s opinion, jeopardizes the subject’s well-being or the 
validity of the study, may be discontinued. 
5.6 
Protocol Deviations 
The date of and reason for deviations will be documented in all cases. Protocol deviations 
impacting the safety of the subject or the integrity of the study must be reported by the 
Investigator to the IRB/EC immediately. Reporting of all other protocol deviations must 
adhere to the requirements of the governing IRB/EC.  
Protocol assessments will continue until the end of the study, unless the protocol 
deviations put the subject at risk or the subject’s condition requires that he/she be 
discontinued from the study. 
6.0 
ADVERSE EVENTS 
6.1 
Definition of Adverse Events 
• 
Any untoward medical occurrence in a subject participating in a clinical study which 
does not necessarily have a causal relationship with the study procedure or with the 
study treatment.  
• 
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease with onset following the signing of informed consent through 
study exit, whether or not considered related to the study. An AE can also include a 
progression/worsening of underlying disease, hypersensitivity, and extravasation. 
• 
Events occurring from drug overdose, whether accidental or intentional, events 
occurring from drug abuse, drug misuse, drug interactions, drug dependency, events 
occurring from drug withdrawal, and medication errors. 
6.2 
Definition of Serious Adverse Events  
Information about every serious adverse event (SAE) will be collected and recorded. An 
SAE is any untoward medical occurrence (at any dose) that results in any of the 
following outcomes: 
• 
death  
• 
a life-threatening adverse drug experience 
• 
inpatient hospitalization or prolongation of existing hospitalization 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 34 
• 
a persistent or significant disability/incapacity 
• 
a congenital anomaly/birth defect 
• 
is sight threatening (may result in persistent or significant loss of vision) 
• 
encompasses any medically significant event that may jeopardize a subject and may 
require medical or surgical intervention to prevent any of the outcomes listed above  
• 
is medically significant, as determined by the Principal Investigator or medically 
qualified Sub-Investigator 
As above, important medical events that may not have resulted in death, be life-
threatening, or require hospitalization may be considered an SAE when, based upon 
appropriate medical judgment, they may jeopardize the subject and may require medical 
or surgical intervention to prevent one of the outcomes listed in this definition. Examples 
of such medical events include allergic bronchospasm requiring intensive treatment in an 
emergency room or at home, blood dyscrasias or convulsions that do not result in 
inpatient hospitalization, or the development of drug dependency or drug abuse. 
Additionally, any suspected transmission of an infectious agent by a Bausch + Lomb 
product, pathogenic or non-pathogenic, is considered an SAE. The event may be 
suspected from clinical symptoms or laboratory findings indicating an infection in a 
subject exposed to a Bausch + Lomb product. The terms “suspected transmission” and 
“transmission” are considered synonymous.  
Hospitalization is a criterion for assessment of seriousness. Hospitalization in the absence 
of a medical AE is not in itself an AE. For example, the following reports of 
hospitalization without a medical AE should not be considered either serious, or an AE: 
• 
admission for treatment of a pre-existing condition not associated with the 
development of a new AE or with worsening of the pre-existing condition (eg, for 
work-up of persistent pre-treatment lab abnormality) 
• 
social admission (eg, subject has no place to sleep) 
• 
administrative admission (eg, for yearly physical exam) 
• 
optional admission not associated with a precipitating medical AE (eg, for elective 
cosmetic surgery) 
6.3 
Reporting Adverse Events and Follow-up 
Throughout the course of the study, efforts will be made by the Investigator to remain 
alert to possible AEs that are either systemic or ocular in nature. The period of 
observation for collection of AEs extends from the time the subject’s parent/legal 
guardian gives informed consent until the last study visit, Visit 8 (Postoperative Day 90). 
The first concern will be the safety of the subject, and appropriate medical intervention 
will be made. 
The Investigator or designee will elicit reports of AEs from the subject/subject’s 
parent/legal guardian at each study visit and record all AEs. An assessment of all AEs 
will be made by the Investigator as to the severity, action taken with study treatment, and 
causal relationship to study drug.  
The terms used to assess the causal relationship of the event to the study drug are:  

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 35 
• Related: There is at least a reasonable possibility that the AE/SAE is related to 
the study drug.  Reasonable possibility means that there is evidence to suggest a 
causal relationship between the drug and the AE. 
• Not Related: There is little or no reasonable possibility that the AE/SAE is 
related to the study drug. This assessment implies that the AE/SAE has little or no 
temporal relationship to the study drug and/or a more likely or certain alternative 
etiology exists. 
When the investigator assesses the AE as “not related” to the study drug, an alternative 
etiology (ie, concomitant drug, medical history, prior AE, or other source as indicated) 
must be provided.    
The subject’s parent/legal guardian will be instructed to contact the Investigator 
immediately if any unusual systemic or ocular AEs are noticed between visits. 
Additional assessments/visits may be scheduled, as necessary, to ensure the safety of the 
subject, during the study period. A subject who discontinues due to an AE should be seen 
for post-study follow-up visits as necessary. 
Non-serious AEs that are ongoing upon early discontinuation or at the study exit visit will 
be followed by the Investigator up to 30 days after the subject exits the study. 
6.4 
Reporting Serious Adverse Events and Follow-up 
Any SAE must be reported to Bausch + Lomb Global Safety & Vigilance; independent of 
the circumstance or suspected cause, within 24 hour s from the time the event was 
reported to the Investigator. All SAEs experienced from consent through the Exit Visit 
(Visit 8, Postoperative Day 90) must be reported to Bausch + Lomb regardless of the 
relationship to the study drug. After the Exit Visit (Visit 8, Postoperative Day 90), or 
following early discontinuation from the study, only SAEs considered related to the study 
drug should be reported promptly. For US sites, these should be reported to Bausch + 
Lomb Global Safety & Vigilance; for EU sites, these should be reported to the EU Study 
Manager who will be responsible for forwarding to Bausch + Lomb Global Safety & 
Vigilance; for AP sites, these should be reported to Bausch + Lomb AP Global Safety & 
Vigilance (Seoul, Korea), who will be responsible for forwarding to Bausch + Lomb 
Global Safety & Vigilance (Madison, NJ, US). Within 24 hour s of notification the 
Investigator will fax a completed Serious Adverse Event Report to the Bausch + Lomb 
contact noted below. For SAEs with fatal outcomes, a summary of available autopsy 
findings should be submitted as soon as possible.

The Investigator or Bausch + Lomb, as appropriate for local regulations, will notify their 
IRB/EC in writing of any SAE in accordance with the IRB/EC requirements. 
Bausch + Lomb or its designee will be responsible for submitting SAE reports to 
regulatory authorities based on applicable regulations. The Sponsor will also send a 
notification to all participating Investigators of any SAE that is unexpected and 
associated with the study (refer to Section 6.5). This notification will be made within 15 
calendar days from the time Bausch + Lomb becomes aware of the event.  
If the Investigator becomes aware of any new information regarding a Serious Adverse 
Event (ie, resolution, change in condition, or new treatment), a new Serious Adverse 
Event Form must be completed and faxed to Bausch + Lomb (refer to contact information 
above) as soon as new information becomes available. The original SAE form is not to be 
altered. The report should describe whether the event has resolved or continues and how 
the event was treated.  
Serious adverse events that have previously been reported, and that continue after the 
subject’s discontinuation or completion of the study will be followed until their medical 
endpoints are determined or until no further change in the conditions is expected. For US 
sites, the events and endpoints will be reported in writing by the Investigator to Bausch + 
Lomb Global Safety & Vigilance; for the EU sites, the SAE form should be sent to the 
EU Study Manager who will be responsible for forwarding to Bausch + Lomb Global 
Safety & Vigilance; for AP sites,  these should be reported to Bausch + Lomb AP Global 
Safety & Vigilance (Seoul, Korea), who will be responsible for forwarding to Bausch + 
Lomb Global Safety & Vigilance (Madison, NJ, US). 
Following the subject's discontinuation or completion of the study, for any timeframe 
afterward deemed medically significant, any SAEs, which are assessed as causally related 
to study drug, should also be reported to Bausch + Lomb Global Safety & Vigilance.  
6.5 
Submitting an Expedited Safety Report to the IRB (Central or Local) 
Any Suspected Unexpected Serious Adverse Reaction (SUSAR) or unexpected SAE 
related to a subject’s participation in the study, regardless if the study drug was 
administered, warrants expedited reporting.  
Each expedited safety report will routinely include a brief cover memorandum, the 
completed MedWatch Form FDA 3500A or Council for International Organizations of 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 37 
Medical Sciences I Form (CIOMS I Form), or relevant reporting form for the global 
region. Where relevant, a clinical analysis of the event with any similar events that have 
occurred with the product, and any additional pertinent information recommended by the 
study Medical Monitor. Once the report is compiled by Bausch + Lomb Global Safety & 
Vigilance, the site Investigator must submit the expedited safety report to the local 
IRB/EC and for EU sites the Sponsor will submit them to the EC and health authorities 
within the required reporting timeframe. Follow-up reports should be submitted when 
requested or when pertinent information becomes available. The site principal 
Investigators must retain a complete copy of each expedited safety report as it was 
submitted to the IRB/EC. It is important that the principal Investigators review these 
expedited reports, as they contain safety information that may be relevant to each of the 
participating subjects.

The secondary efficacy endpoints are as follows: 
• 
mean grade of anterior chamber inflammation at Visits 4 and 6 (Postoperative Days 7 
and 28) 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 38 
• 
proportion of subjects with Grade 0, Grade 1, Grade 2, Grade 3, and Grade 4 
converted anterior chamber inflammation at each visit (Postoperative Days 7, 14, and 
28) 
• 
presence/absence and total area, if present, of synechiae at each visit (Postoperative 
Days 7, 14, and 28) 
• 
presence/absence and total number, if present, of precipitates on t he implant and 
cornea at each visit (Postoperative Days 7, 14, and 28) 
7.1.3 
Safety Endpoints 
The safety endpoints are as follows: 
• 
incidence of overall and specific AEs 
• 
type and incidence of AEs at each visit  
• 
change in IOP from baseline (Visit 2, Surgery/Randomization) to each visit 
• 
greatest IOP change from baseline - including the measurement at Visit 3 
(Postoperative Day 1) 
• 
greatest IOP change from baseline - excluding the measurement at Visit 3 
(Postoperative Day 1) 
• 
ocular signs (biomicroscopic examination of the lids, conjunctiva, cornea, anterior 
chamber without pupil dilation) at each visit 
7.1.4 
Tolerability Endpoints 
The tolerability endpoint is as follows: 
• 
ocular symptoms (photophobia) at each visit 
7.2 
Hypotheses 
Test for the non-inferiority of LE Ophthalmic Gel, 0.5% to Prednisolone Acetate 
Ophthalmic Suspension, 1% will be primarily based on t he following one-sided null 
hypothesis (Ho) and alternative hypothesis (Ha): 
Ho: µLE - µPR ≥ 0.35     versus              Ha: µLE - µPR < 0.35 
where µLE and µPR are the mean grade of anterior chamber inflammation at Visit 4 
(Postoperative Day 7) for LE Ophthalmic Gel, 0.5% and Prednisolone Acetate 
Ophthalmic Suspension, 1% treatment group, respectively. 
7.3 
Sample Size 
A sample size of 120 subjects (60 subjects per treatment group) yields 98% power to 
detect non-inferiority of LE Ophthalmic Gel, 0.5% to Prednisolone Acetate Ophthalmic 
Suspension, 1%. This sample size assumes a common standard deviation of 0.47, a two-
sided alpha=0.05, a non-inferiority margin of 0.35 and an expected difference of 0 for the 
difference in means between treatment groups using anterior chamber inflammation at 
Visit 5 (Postoperative Day 14).  Assuming a subject dropout rate (including the initiation 
of rescue medication) of 12%, approximately 140 subjects will be randomized, of which 
at least 60 subjects will be in the age group 0-3 years as per the FDA’s Written Request. 
The power and sample size calculations were done using nQuery Advisor version 7.0.  

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 39 
7.4 
Randomization 
A total of 140 subjects from ages 0-11 will be randomized to receive LE Ophthalmic Gel, 
0.5% or Prednisolone Acetate Ophthalmic Suspension, 1% in a 1:1 ratio. The subgroup 
age 0-3 years will consist of at least 60 subjects.  
7.5 
Analysis Populations 
The analysis populations that will be used in this study are: 
• 
Intent-to-Treat (ITT) Population: includes all subjects who were randomized and have 
at least one post-treatment assessment. Analysis on the ITT population will be used 
for primary efficacy analyses and will be performed for all efficacy endpoints, 
analyzing subjects under the treatment to which they were randomized.  
• 
Per Protocol (PP) Population: includes all of the subjects in the ITT population that 
remained in the study through Visit 5 (Postoperative Day 14) and who did not deviate 
from the protocol in any way likely to seriously affect the primary outcome of the 
study. Analysis using the PP population will be used to supplement the ITT analysis, 
analyzing subjects according to the treatment received.  
• 
Safety Set: includes all participants who received at least one dose of study drug. 
7.6 
Statistical Analysis  
7.6.1 
Methods of Analysis 
Summaries for continuous variables will include the sample size, mean, standard 
deviation (SD), median, minimum, and maximum. Summaries for discrete variables will 
include the tabulation of frequencies and percentages. Means and medians will be 
presented to one more decimal place than the recorded data. Standard deviations will be 
presented to two more decimal places than the recorded data. Minimum and maximum 
values will be presented using the same number of decimal places as the recorded data. 
Confidence intervals (CIs) will be presented using the same number of decimal places as 
the parameters (eg, mean). Percentages will be presented to one decimal place.  
The primary efficacy analysis will be based on the ITT population with missing data 
imputed using the last observation carried forward (LOCF) method  and the primary 
endpoint mean grade of anterior chamber inflammation at Visit 5 (Postoperative Day 14). 
The mean grade of anterior chamber inflammation at Visit 5 (Postoperative Day 14) will 
be analyzed using an analysis of variance (ANOVA) model with treatment as a 
classification variable. 
The least squares mean for each treatment group, the difference in the least squares mean 
between the two treatment groups (LE Ophthalmic Gel, 0.5% – Prednisolone Acetate 
Ophthalmic Suspension, 1%), and the two-sided 95% confidence interval for the 
difference will be presented. The null hypothesis will be rejected and non-inferiority 
established if the upper limit of the confidence interval does not exceed0.35.  
To supplement the primary analyses, the analyses above will be repeated for the PP 
population; no imputation will be conducted for missing data. Any discrepancy between 
the ITT and PP analyses will be explained. 
The secondary efficacy analyses will be conducted based on the ITT population as well 
as the PP population. 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 40 
As a secondary analysis, the analysis of the mean grade of anterior chamber inflammation 
will be repeated as above for Visits 4 and 6 (Postoperative Days 7 and 28, respectively). 
Additional secondary analyses include:  
• 
the proportion of subjects with anterior chamber inflammation of Grade 0, Grade 1, 
Grade 2, Grade 3, and Grade 4 for each visit (Postoperative Days 7, 14, and 28) 
• 
the proportion of subjects with presence/absence and total area, if present, of 
synechiae for each visit (Postoperative Days 7, 14, and 28) 
• 
the proportion of subjects with presence/absence and total number, if present, of 
precipitates on the implant and cornea at each visit (Postoperative Days 7, 14, and 28) 
For each of the above endpoints, treatment groups will be compared using the Pearson 
Chi-squared test or fisher’s exact test as appropriate. Differences between the proportions 
of treatment groups and 95% confidence interval about the differences will be presented. 
Subgroup analyses will be performed for anterior chamber inflammation, anterior 
chamber cells, and anterior chamber flare as appropriate by method of assessment (slit 
lamp versus penlight with handheld magnifying 20 diopter lens), country (region), age 
group, IOL implantation, and iris color. 
All subjects in the safety set will be included in the safety analyses. Intraocular pressure 
will be summarized by visit using continuous summaries (including change from baseline 
and change from screening) for the following items: 
• 
change in IOP from baseline (Visit 2, Surgery/Randomization) to each visit 
• 
greatest IOP change from baseline - including the measurement at Visit 3 
(Postoperative Day 1) 
• 
greatest IOP change from baseline - excluding the measurement at Visit 3 
(Postoperative Day 1) 
• 
ocular signs (biomicroscopic examination of the lids, conjunctiva, cornea, anterior 
chamber without pupil dilation) 
Treatment emergent systemic AEs will be summarized using discrete summaries at the 
subject and event level by system organ class and preferred term for each treatment group. 
Treatment emergent ocular AEs will be summarized for treated eyes and fellow eyes 
separately. Similarly, treatment emergent AEs will be summarized by severity and 
relationship separately. All AEs will be coded using a MedDRA dictionary (the most 
current version available at the start of the study will be used). 
Ocular symptoms will be summarized using discrete summary statistics by visit and 
treatment group. These data will be summarized under the safety analyses.  
7.6.2 
Subject Demographics and Baseline Characteristics 
Subject demographics: race, gender, and age will be summarized using discrete summary 
statistics. Age will also be presented using continuous summary statistics. 
7.6.3 
Subject Disposition 
A disposition of subjects includes the number and percentage of subjects in each of the 
following categories: 
• 
subjects randomized (ITT population) 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 41 
• 
subjects treated (Safety population) 
• 
subjects in the PP population 
Within each of the previous categories, the number and percentage of subjects who 
completed and discontinued from the study will be summarized. The primary reason for 
study discontinuation described in Section 3.2.4 will also be summarized.  
7.6.4 
Protocol Deviations 
The number of subjects within each type of protocol deviations will be presented using 
listings and discrete summary statistics as appropriate.  
7.6.5 
Treatment Compliance 
Treatment compliance will be assessed as the percentage of prescribed instillations 
received and will be presented using discrete summary statistics in the following 
categories: (≤ 50%, 51-60%, 61-70%, 71-80%, 81-120%, and > 120%). Percentages will 
be calculated out of the number of subjects who returned diaries from that dosing period. 
The number and percentage of subjects in each compliance rate category will be 
presented. 
7.6.6 
Treatment Exposure 
Extent of exposure is defined as the total number of days from the first dose date to the 
last dose date, as recorded at the randomization study visit and the study exit eCRF page. 
Subjects who fail to return all bottles dispensed will be excluded from this summary. The 
extent of exposure will be summarized using continuous summary statistics. 
7.6.7 
Missing Data 
For the primary efficacy endpoint analyzed using the ITT population, missing data and 
data from subjects placed on r escue medication will be imputed using the LOCF 
methodology. For the PP analysis, missing data and data from subjects placed on rescue 
medication will not be imputed.

• 
test article accountability 
During the course of the study, if the Sponsor determines that an Investigator is  
non-compliant with the study plan and/or applicable regulatory requirements, the Sponsor 
will take action to secure compliance. In addition, the Sponsor may terminate the 
Investigator’s participation in the study if appropriate, or if the Investigator remains  
non-compliant despite the Sponsor’s actions. 
8.2 
Source Documentation 
All medical information obtained at each study visit must be recorded in the subject’s 
record (source documentation) in real time as it is collected. Source documentation 
consists of original subject documents, as well as data and records with information 
relevant to the subject and his/her participation in the study.  
Subject completed forms are also considered source data. Designated site personnel will 
pre-record appropriate dates of study drug administration and subject identifiers (initials 
and/or study number) on the diary. With this exception, only subject’s parents/legal 
guardians are to record information in subject diaries and questionnaires. In no instance, 
should an Investigator or study site personnel record any data or make changes to subject 
completed forms. The Investigator or designee should review subject completed forms 
during study visits. If an entry is found to be illegible or a mistake is found (eg, incorrect 
year was recorded), the subject’s parent/legal guardian should be instructed to edit the 
entry by drawing a single line through the original entry, entering the new information, 
and dating and initialing (US and AP only)/writing year of birth to acknowledge (EU 
only) the change. 
8.3 
Case Report Forms and Data Verification 
Subject data required by this protocol are to be recorded on eCRFs. The Investigator and 
study site personnel will be responsible for completing the eCRFs. The Investigator is 
required to verify that all of the requested information is accurately recorded on t he 
eCRFs. All information requested on the eCRFs needs to be supplied, including subject 
identification, date(s), assessment values, etc, and any omission or discrepancy will 
require explanation. All information on eCRFs must be traceable to source documents.  
The study monitor will be responsible for reviewing and verifying the data recorded on 
the eCRFs, utilizing the original source documentation and will query discrepant findings. 
The Investigator and study site personnel will be responsible for answering all queries. 
The eCRFs will be submitted electronically via an electronic data capture system to 
Bausch + Lomb Global Clinical Operations for quality assurance review, data entry, and 
statistical analysis.  
A copy of the eCRFs (on CD or DVD) will be retained by the Investigator at the 
conclusion of the study, who must ensure that it is stored in a secure place.

8.4 
Recording of Data and Retention of Documents 
Subject data recorded on eCRFs during the study will be documented in a coded fashion. 
The subject will only be identified by the subject number, and by their year of birth. 
Confidentiality of subject records must be maintained to ensure adherence to applicable 
local privacy regulations. 
The Investigator must retain essential documents indefinitely after the completion of the 
study, unless otherwise notified by the Sponsor. The Investigator agrees to adhere to the 
document retention procedures when signing the protocol Investigator Statement of 
Approval.  
Essential documents include but are not limited to the following: 
• 
IRB/EC approvals for the study protocol, all amendments, ICF(s), and advertisements 
• 
IRB/EC annual study review 
• 
IRB/EC correspondence and reports (eg, SAE reports, protocol deviations, and safety 
updates) 
• 
regulatory documents (eg, financial disclosure and delegation of authority forms) 
• 
all source documents  
• 
copy of eCRFs 
• 
subject’s signed ICF 
• 
FDA Form 1572 
• 
accountability records for the test article(s) 
• 
correspondence from and to the Sponsor 
• 
any other documents relevant to the conduct of the study 
In the event that the Investigator withdraws from the study (eg, retirement, relocation), 
study records will be transferred to a mutually agreed upon d esignee (eg, another 
Investigator, site IRB/EC). The Investigator will provide notice of such transfer in writing 
to Bausch + Lomb Global Clinical Operations. 
8.5 
Auditing Procedures 
Audits of clinical research activities in accordance with the Sponsor’s internal Standard 
Operating Procedures (SOPs) to evaluate compliance with the principles of GCP may 
take place. A regulatory authority may also wish to conduct an inspection (during the 
study or after its completion). If an inspection is requested by a regulatory authority 
and/or IRB/EC, the Investigator must inform the Sponsor immediately that this request 
has been made. 
8.6 
Institutional Review Board/Ethics Committee Approval 
In the US and AP, the Investigator, or in the EU, the Sponsor or designee should ensure 
that participation in the study, in addition to the protocol, subject recruitment materials 
(written information or materials including web pages, radio advertisements, television 
spots or written text developed to encourage subject enrollment) and the ICF to be used 
in this study are approved by their institution IRB/EC, or if not using their institution's 
IRB/EC, approved by the reviewing central IRB/EC prior to entering any subjects in the 
study. Documentation of IRB/EC approval of the study protocol and informed consent 
must be provided to the Sponsor prior to initiation of the study. In addition, in the US and 
AP, the Investigator, or in the EU, the Sponsor or designee must ensure that the 
reviewing IRB/EC has provided approval for any protocol amendments prior to 

Study #670 - Protocol 
Amendment 6, 22 May 2013 
 
Page 44 
implementation. If the amendment necessitates a revision to the ICF, the Investigator 
should ensure the revised form is also submitted to and approved by the Sponsor and the 
IRB/EC prior to implementation.  
8.7 
Publication of Results 
All study data generated as a result of this study will be regarded as confidential, until 
appropriate analysis and review by the Sponsor or its designee and the Investigator(s) are 
completed. The results of the study may be published or presented by the Investigator(s) 
after the review by, and in consultation and agreement with the Sponsor, and such that 
confidential or proprietary information is not disclosed. 
Prior to publication or presentation, a copy of the final text should be forwarded by the 
Investigator(s) to the Sponsor or its designee, for comment. Such comments shall aim to 
ensure the scientific integrity of the proposed publications and/or presentations and 
ensure that the data and material referring to Bausch & Lomb Incorporated products and 
activities receive fair, accurate, and reasonable presentation.

1 All ophthalmic assessments will be performed bilaterally. 
2 Visit 2 must occur within 29 days of Visit 1. Screening and surgery cannot take place on the same day.  
3 Visit 3 (postoperative day 1) should occur on the next calendar day post-surgery.  
4 Every effort should be made to obtain slit lamp assessments and the assessment with the 20 dpt magnifying lens and penlight should only be performed if a slit lamp or handheld 
slit lamp examination cannot be performed. Once one of the methods has been chosen it should be employed throughout the study for each subject. IOP should also be measured 
with the same method throughout the study for each subject.  
5 Fundoscopy will be performed bilaterally either at Visit 2 (surgery/randomization) or Visit 3 (postoperative day 1), at Visit 5 (postoperative day 14 ±3 days), and at Visit 8 
(postoperative day 90 ±14 days). 
6 Collection of AEs extends from the time the subject’s parent/guardian signs informed consent until the last study visit. 
7 The subject’s parent/legal guardian will be trained with regard to the correct instillation of eye drops without using study drug prior to their administration of the initial dose.

APPENDIX B: 
METHODS OF CLINICAL EVALUATION  
Any changes to the procedures described in this appendix will be provided under separate 
cover. 
All ophthalmic assessments will be performed bilaterally at all visits. 
1. PEDIATRIC VISUAL ACUITY 
Whenever possible best corrected (if applicable) Snellen distance VA will be measured in 
both eyes. Otherwise, the Investigator will attempt the following techniques in sequential 
order:

5. OCULAR SYMPTOMS 
Photophobia:  
0 = Absent 
Absence of positive sensation. (For babies, a normal reaction to any 
light source.) 
1 = Mild 
Very minimal light intolerance which may require some degree of 
sunglass protection to eliminate the symptom, noticed primarily in 
sunlight. (For babies, a normal reaction to room light but more 
squinting or discomfort is shown to brighter room light or sunlight 
than normal reaction.) 
2 = Moderate 
Infrequent or intermittent discomfort in the globe associated with 
exposure to room light or sunlight which is only partially relieved by 
dark glasses or subdued light. The symptoms still persist to some 
degree even with sunglasses. (For babies, discomfort at normal room 
light is shown and more comfort is shown in dimly lit environments.) 
3 = Severe 
Constant or nearly constant exquisite pain in the eye that is not 
relieved by sunglasses and is only relieved by total occlusion of the 
eye. This total occlusion can be achieved with an eye patch or by 
closing the eyes. This sensation is severe enough to commonly require 
bed rest and, in some instances, systemic sedation. (For babies, 
squinting of the eyes or crying at any light source is shown and only 
total occlusion seems comforting.)
