Clinical Evaluation of a Daily Wear Frequent Replacement Silicone Hydrogel Lens

Not Applicable

Completed

• Conditions: Refractive Errors

• Registration Number: NCT03920280
• Lead Sponsor: Alcon Research

Brief Summary

The purpose of this clinical study is to demonstrate the safety and performance of an investigational soft contact lens compared to a commercially available soft contact lens when worn in a daily wear modality.

Detailed Description

Subjects will be randomized to wear either the investigational contact lenses or the commercially available contact lenses in both eyes. Subjects will be expected to attend 6 scheduled study visits. Individual participation in the study will be approximately 3 months.

Primary Outcome Measures

Name	Time	Method
Distance Visual Acuity (VA) With Study Lenses - Completed Eyes	Day 1 Dispense; Week 1 Follow-up; Week 2 Follow-up; Month 1 Follow-up; Month 2 Follow-up; Month 3 Follow-up/Exit (at least 4 hours after lens insertion at each follow-up assessment visit)	Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters using a letter chart. VA was collected in Snellen and converted to logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with lower logMAR values indicating better visual acuity. No formal hypothesis testing was planned.
Distance Visual Acuity (VA) With Study Lenses - Discontinued Eyes	Day 1 Dispense; Week 1 Follow-up; Week 2 Follow-up; Month 1 Follow-up; Month 2 Follow-up (at least 4 hours after lens insertion at each follow-up assessment visit)	Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters using a letter chart. VA was collected in Snellen and converted to the logarithm minimum angle of resolution (logMAR) scale. A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with lower logMAR values indicating better visual acuity. No formal hypothesis testing was planned.
