Systane Hydration in Subjects Undergoing Cataract Surgery
The primary objective of this study is to demonstrate reduced corneal staining with use of Systane Hydration among subjects with dry eye disease (DED) undergoing routine cataract removal and monofocal intraocular lens (IOL) implantation.
|Condition or Disease||Intervention/Treatment||Phase|
Subjects will attend 6 scheduled study visits for an individual duration of participation of 6 weeks. One eye (study eye) will be followed.
Arms and Interventions
|Experimental: Systane Hydration|
Systane Hydration lubricant eye drops dosed 4 times a day for 6 weeks (2 weeks prior to surgery and 4 weeks post surgery), with investigator defined post-operative standard of care
Other: Systane Hydration lubricant eye drops
Sterile solution indicated for the temporary relief of burning and irritation due to dryness of the eye
|No Intervention: No Treatment|
Investigator defined post-operative standard of care
Primary Outcome Measures
- Corneal staining [Up to Day 30 post-operative]
The National Eye Institute (NEI) grading scale will be used to evaluate the five corneal regions: Superior, inferior, central, temporal and nasal. Each region will be graded on a 0-3 scale, where 0 = normal (no staining), 1 = mild/superficial stippling micropunctate staining, 2 = moderate/macropunctate staining with some coalescent areas, and 3 = severe/numerous coalescent macropunctate areas and/or patches. The regions will be summed for a resultant overall score of 0 to 15.
Secondary Outcome Measures
- DEQ-5 Score [Up to Day 30 post-operative]
The Dry Eye Questionnaire-5 (DEQ-5) is a patient-reported outcome measures questionnaire designed to assess symptoms of dry eye disease. Subjects will respond to 5 questions using a 0-4 Likert-type scale, for a resultant overall score of 0 (best) to 20 (worst).
- Ocular Comfort Questionnaire Score: My eyes are comfortable [Up to Day 30 post-operative]
Subjects will provide a comfort score (strongly disagree, disagree, neither agree nor disagree, agree, strongly agree) to the following question: "My eyes are comfortable."
- Ocular Comfort Questionnaire Score: At the end of the day, my eyes feel comfortable [Up to Day 30 post-operative]
Subjects will provide a comfort score (strongly disagree, disagree, neither agree nor disagree, agree, strongly agree) to the following question: "At the end of the day, my eyes feel comfortable."
- Ocular Comfort Questionnaire Score: My eyes are comfortable all day long [Up to Day 30 post-operative]
Subjects will provide a comfort score (strongly disagree, disagree, neither agree nor disagree, agree, strongly agree) to the following question: "My eyes are comfortable all day long."
