Brief summary:
Systane Hydration PF is a recently released preservative-free artificial tear that is able to supplement the ocular surface's moisture while simultaneously soothing the eye. While Systane Hydration PF should in theory improve the symptoms and subsequently the quality of life of patients who have DES, this clinical application has yet to be tested. This drop furthermore is available in both unit-dose and multi-dose options; however, it is unclear if patient perceive a difference between the two dispensing methods. Therefore, the primary purpose of this study is to recruit patients who have DES and to treat them with Systane Hydration PF and determine how regular use of this drop impacts a patient's ocular surface symptoms and overall quality of life. This study will secondarily compare the two dispensing methods to determine if patients prefer one method over the other.

Detailed description:
Extensive computer use is no longer an employment-specific challenge. Use of digital devices in work, home, and leisure settings is now the norm, and it is now socially expected. While the introduction of high-powered computers and digital devices have greatly improved many aspects of modern life, the pervasive use of digital devices has caused some patients to develop a condition known as Digital Eye Strain (DES). DES has been reported to be as high as 93% the population depending upon how the condition is defined, and its severity has been found to increase with increased digital device time. DES is a condition where patients experience symptoms such as glare, accommodative dysfunction, defocus, fatigue, discomfort, and dryness from digital device use, and these dry eye symptoms may also result in decreased quality of life. While dryness symptoms in DES are likely multifactorial (e.g., contact lens use, systemic disease status), much of the dryness symptoms in DES are probably due to tear film evaporation secondary to having a reduced number of blinks per minute while using digital devices. Since much of the ocular symptoms associated with DES stem from excessive tear evaporation, artificial tears have become an accepted DES treatment

Systane Hydration PF is a recently released preservative-free artificial tear that is able to supplement the ocular surface's moisture while simultaneously soothing the eye. Systane Hydration PF has HydroBoost technology, which is thought to enhance the drop's effectiveness by incorporating ingredients that increase drop retention. While Systane Hydration PF should in theory improve the symptoms and subsequently the quality of life of patients who have DES, this clinical application has yet to be tested. This drop furthermore is available in both unit-dose and multi-dose options; however, it is unclear if patient perceive a difference between the two dispensing methods. Therefore, the primary purpose of this study is to recruit patients who have DES and to treat them with Systane Hydration PF and determine how regular use of this drop impacts a patient's ocular surface symptoms and overall quality of life. This study will secondarily compare the two dispensing methods to determine if patients prefer one method over the other.

Arms: arm 1: Subjects randomized to this group will apply the unit-dose version of Systane Hydration PF to determine if it helps alleviate symptoms associated with digital eye strain. arm 2: Subjects randomized to this group will apply multi-dose version of Systane Hydration PF to determine if it helps alleviate symptoms associated with digital eye strain.
Interventions: intervention 1: Systane Hydration PF
Intervention descriptions: intervention 1: This is an over-the-counter preservative free artificial tear that can be purchased at most retail stores and pharmacies.

Title of Research:
Understanding Quality of Life in High Digital Device Users who are Treated 
with a Preservative Free Artificial Tear   
UAB IRB Protocol #:

ALCON RESEARCH, LTD
General Information
You are being asked to take part in a research study. This research study is 
voluntary, meaning you do not have to take part in it. The procedures, risks, and 
benefits are fully described further in the consent form.
Purpose
The purpose of the study is to determine the effect of a preservative free artificial 
tear on dry eye symptoms and visual quality of life in patients who have Digital 
Eye Strain (DES).
Duration & Visits
You will be in this study for 2 weeks with 3 in person visits with each visit lasting 
about 1 hour.
Overview of Procedures
This study will include eye tests, surveys, and the use of an over the counter, 
preservative free artificial tear. You will be randomly placed by chance in either 
the unit-dose drop group or the multi-dose drop group at the first visit. You will 
then be switched to the other group at the second visit. Both dispensing methods 
contain the same artificial tear. 
Risks
The risks of this study do not exceed that of a normal eye exam. The use of all eye 
drops comes with a risk of eye irritation or an allergic reaction; however, allergic 
reactions with these drops are very rare.
Benefits
You may not benefit directly from this study, but knowledge gained from this 
study could potentially help future persons suffering from eye discomfort or DES.
Alternatives
The only alternative to this study is to not take part in this study and to continue 
with your regular eye care.
Purpose of the Research Study
We are asking you to take part in a research study. Although the use of digital devices has greatly improved 
many aspects of modern life, heavy use of digital devices can lead to the development of a condition known as 
Digital Eye Strain (DES). DES is a condition where patients experience symptoms such as glare, trouble with 
focusing, visual blur, fatigue, eye discomfort and dryness as well as an overall lower quality of life. This study 
plans to determine if symptoms associated DES can be reduced or alleviated with the use of a preservative free 
artificial tear. This study will also compare two ways to dispense these drops (unit-dose vs. multi-dose). We 
plan to enroll a total of 30 subjects at the University of Alabama at Birmingham.
Conflict of Interest Disclosure
Dr. Andrew Pucker, the principal investigator for this study, receives consulting fees from companies other 
than the sponsor, which may affect his financial interests. If you would like more information, please ask Dr.

Risks and Discomforts


Page 3 of 5
FOR206 Version Date: 03/21/2021
This study does not involve any inherent risks or discomforts, though there is a chance that you may find the 
drops to sting slightly upon instillation. This is a common and accepted issue with eye drops; however, it is 
unlikely since these drops are designed to improve eye comfort. If you find any of the eye tests or the drops to 
be uncomfortable, you will be allowed to stop the study at any time. There is also a risk of breach of 
confidentiality; however, every reasonable precaution has been taken to avoid this potential risk. 
Benefits
You may not benefit directly from taking part in this study. However, knowledge gained from this research will 
help the medical community better understand if preservative free artificial tears can help reduce or alleviate 
the symptoms associated with DES. 
Alternatives
Your alternative is to not participate in this study.

I. INTRODUCTION & RATIONALE 
 
Extensive computer use is no longer an employment-specific challenge. Use of digital devices in work, home, 
and leisure settings is now the norm, and it is now socially expected.1 While the introduction of high-powered 
computers and digital devices have greatly improved many aspects of modern life, the pervasive use of digital 
devices has caused some patients to develop a condition known as Digital Eye Strain (DES). DES has been 
reported to be as high as 93% the population depending upon how the condition is defined, and its severity 
has been found to increase with increased digital device time.1, 2 DES is a condition where patients experience 
symptoms such as glare, accommodative dysfunction, defocus, fatigue, discomfort, and dryness from digital 
device use,2 and these dry eye symptoms may also result in decreased quality of life.3 While dryness 
symptoms in DES are likely multifactorial (e.g., contact lens use, systemic disease status), much of the dryness 
symptoms in DES are probably due to tear film evaporation secondary to having a reduced number of blinks 
per minute while using digital devices.2 Since much of the ocular symptoms associated with DES stem from 
excessive tear evaporation, artificial tears have become an accepted DES treatment.2  
 
Systane Hydration PF is a recently released preservative-free artificial tear that is able to supplement the 
ocular surface’s moisture while simultaneously soothing the eye. Systane Hydration PF has HydroBoost 
technology, which is thought to enhance the drop’s effectiveness by incorporating ingredients that increase 
drop retention. While Systane Hydration PF should in theory improve the symptoms and subsequently the 
quality of life of patients who have DES, this clinical application has yet to be tested. This drop furthermore is 
available in both unit-dose and multi-dose options; however, it is unclear if patient perceive a difference 
between the two dispensing methods. Therefore, the primary purpose of this study is to recruit patients who 
have DES and to treat them with Systane Hydration PF and determine how regular use of this drop impacts a 
patient’s ocular surface symptoms and overall quality of life. This study will secondarily compare the two 
dispensing methods to determine if patients prefer one method over the other.  
 
II. SPECIFIC AIM 
 
Aim: Determine the effect of Systane Hydration PF on dry eye symptoms and visual quality of life in 
subjects who have Digital Eye Strain (DES).  
Hypothesis 1: Systane Hydration PF will significantly improve IDEEL Work scores in heavy digital device 
users (≥ 8 hours of wear/day).  
Hypothesis 2: Subjects will report higher ease of use satisfaction when using multi-dose Systane Hydration 
PF compared to unit-dose Systane Hydration PF. 
 
III. STUDY DESIGN  
 
Subjects 
This two-week, three-visit study will be conducted at the University of Alabama at Birmingham (Birmingham, 
AL, USA). A total of 30 subjects will be recruited since this is a descriptive study. Subjects will be recruited from 
each site via clinic records, email, and fliers. Adult (>18 years) patients who answer yes to the following two 
questions and use digital devices (e.g., computers, tablets, or smart phones) ≥8 hours/day will be recruited:  
“Are your eyes dry, irritated, or itchy or do they burn while using a digital screen, like a computer or 
smartphone? Yes or No 
 


“Eye fatigue is the physical discomfort of your eyes after spending periods of time throughout the day in front 
of a digital screen, like a computer or smartphone.”4 Do you have eye fatigue based upon the this definition? 
Yes or No 
Subjects will also be required to have a Work Impact of Dry Eye on Daily Life (IDEEL) score ≤80 to ensure that 
they have clinically meaningful symptoms,5 and they will be required to have an Ocular Surface Disease Index 
(OSDI) score between 13 and 32 (inclusive) to ensure that they have mild to moderate dry eye symptoms.6, 7 
Subjects will be excluded if they had worn contact lenses in the past week or during the course of the study, 
have known systemic health conditions that are thought to alter tear film physiology (e.g., Sjögren's 
syndrome), have a history of ocular surgery within the past 12 months, have a history of severe ocular trauma, 
active ocular infection or inflammation, are currently using isotretinoin-derivatives or ocular medications, are 
currently using a dry eye treatment other than artificial tears, are currently using more than 4 drops of 
artificial tears per day in each eye, or if they are pregnant or breast feeding.8 If subjects are currently using 
artificial tears, they will be required to refrain from using them for at least 24 hours before their baseline visit, 
and they will only be allowed to use Systane Hydration during the study.  
 
Surveys and Clinical Tests 
 
This will be a prospective, investigator-masked clinical trial, which will be registered with ClinicalTrials.gov. 
Subjects who meet all study criteria will be enrolled into the study. The contents of the drops will be concealed 
from the subjects. Clinical measurement will be obtained from both eyes of each subject and testing will be 
performed in the below order. Testing order was designed to sequentially administered the least invasive to 
most invasive test. This methodology will ensure that a previous procedure will have a minimal effect on all 
subsequent assessments.9 Subject will be asked to bring their spectacles to the study visit and to adhere to the 
contact lens exclusion factors described above throughout the study.  
 
Visit 1 
 
1. Subject History, Eligibility, Informed Consent: Subjects will be asked to complete a screening survey at the 
first study visit to verify that they are eligible for the study. All relevant ocular, systemic, and surgical history will 
be gathered via a questionnaire developed by the investigators. This questionnaire will also ask about digital 
device usage and eye comfort while using digital devices. The subjects will complete the OSDI questionnaire, 
and they will be required to have a score between 13 and 32 (inclusive). The subject will be asked to complete 
the Work IDEEL, and they will be required to have a score ≤80. Non-eligible subjects will be dismissed at this 
time or rescheduled depending upon the reason for ineligibility. Eligible subjects will be enrolled, consented, 
and requested to sign a privacy document.  
 
2. Impact of Dry Eye on Daily Life (IDEEL) questionnaire: The full Impact on Daily Life segment of the IDEEL 
questionnaire will be self-administered electronically to understand how quality of life and common daily 
activities are affected by eye comfort (e.g., computer work, near work).10 
 
3. Visual Acuity: The subject’s visual acuity will be measured with a Bailey-Lovie high-contrast (logMAR) chart 
or equivalent. If the patient is unable to read the 20/40 letters (0.3 logMAR), the investigator will pinhole over 
the patient’s unaided or presenting refractive error correction to determine the subject’s visual potential.  
 
4. Slit-Lamp Biomicroscopy: The investigator will use a slit-lamp biomicroscope to document normal and/or 
remarkable findings of the anterior eye structures: eyelashes (blepharitis), eyelids, conjunctiva, and cornea. 
Eyelids will be graded based upon a grading scale that was developed by the investigators. 
 


5. Subject Randomization: The examiner will use an electronic randomization system to place the subject in the 
Systane Hydration Multi-Dose group or the Systane Hydration Unit-Dose group. Subjects will be required to use 
their allocated drop two to four times per day in each eye. 
 
6. Subject Compliance: Subjects will be given a daily log to record the time and number of drops used each day; 
these data will be used to determine drop compliance for each dispensing method. They will also be asked to 
record the duration and type of digital device use each day.  
 
Visit 2 
 
1. Testing: Subjects will be asked to repeat the IDEEL and clinical tests described above at this visit. The 
compliance log will likewise be collected at this visit and a new one will be given.  
 
2. Drop Application Satisfaction Survey: An investigator developed survey will be created based upon the 
glaucoma literature to understand patient satisfaction related to applying Systane Hydration via the Unit-Dose 
and Multi-Dose options.  
 
3. Subject Crossover: Subjects will be switched to the opposite treatment group. No washout period will be 
needed because all subjects will be using Systane Hydration; they will just be applying the drop via the alterative 
dispensing method for the second week of the study. Subjects will be required to use their allocated drop two 
to four times per day in each eye.  
 
Visit 3 
 
1. Testing: Subjects will be asked to repeat the IDEEL and clinical tests described above at this visit. The 
compliance log will likewise be collected at this visit.  
 
2. Drop Application Satisfaction Survey: An investigator developed survey will be created based upon the 
glaucoma literature to understand patient satisfaction related to applying Systane Hydration via the Unit-Dose 
and Multi-Dose options.  
 
3. Study Completion: The examiner will reveal the study details to the subjects (Systane Hydration PF). The 
subject will be compensated for their time, and they will be released from the study at this time.  
 
Data Management & Analysis 
 
Surveys and all data will be collected via a secured web service (REDCap) at the time of the study visit. Gerald 
McGwin, Jr, MS, PhD, Professor and Vice Chairman in the Department of Epidemiology at the University of 
Alabama at Birmingham, will perform the statistical analyses. All data will be analyzed with SAS Version 9.4 
(SAS; Cary, NC, USA). ANOVA, T-tests, and chi-square tests will be used when comparing variables. If the 
assumptions of these tests cannot be met suitable alternative statistical tests (e.g., Wilcoxon Rank Sum Test, 
Fisher’s Exact Test) will be used instead. The questionnaire data will furthermore be presented in a table that 
will describe the frequency by which each subject indicated each questionnaire response.  
 
Training of Study Personnel 
 
Prior to enrolling any subjects all clinical examiners will participate in a meeting run by Dr. Pucker. This full 
investigator meeting will ensure that all study investigators are performing the procedures in the same manner. 


Data from each investigator’s first subject will also be monitored for quality control before sites are allowed to 
enroll additional subjects.

An abstract evaluating the effects of Systane Hydration PF on ocular comfort and quality of life will be 
submitted to the Global Specialty Lens Symposium 2022. A summary of this work will be submitted as a 
manuscript to Contact Lens & Anterior Eye.   
 
VI. Conclusions 
 
This project will provide some of the first data related to the quality of life of patients who have DES who are 
heavy digital device users. It will likewise provide insights into to the usefulness of Systane Hydration PF in 
patients who have DES, and it will provide some of the first guidance related to dosing methods of dry eye 
treatments. Ultimately, after completion of this study, clinicians will have a better understanding of the 
symptomatology surrounding DES and how Systane Hydration PF affects these symptoms.
