Clinical Performance of a Silicone Hydrogel Contact Lens Following Six Nights of Extended Wear

Not Applicable

Completed

• Conditions: Refractive Errors

• Registration Number: NCT03614130
• Lead Sponsor: Alcon Research

Brief Summary

The purpose of this clinical study is to evaluate the on-eye performance of an investigational soft contact lens compared to a commercially available soft contact lens following 1 week of extended wear.

Detailed Description

Subjects will be randomized to wear the investigational contact lens in 1 eye and the commercially available contact lens in the other eye. Subjects will be expected to attend 3 scheduled study visits: Day 1 Baseline/Dispense; Day 2 Follow-up; and Week 1 Follow-up/Exit. The expected duration of exposure to each of the study lenses for all randomized, completed subjects was approximately 7 days / 6 nights of wear.

Inclusion Criteria

• Able to understand and sign an Institutional Review Board/Ethics Committee-approved Informed Consent form.
• Successful wear of spherical soft contact lenses in both eyes during the past 3 months for a minimum of 5 days per week and in an extended wear modality a minimum of 1 night per week.
• Best Corrected Visual Acuity (BCVA) of 20/25 or better in each eye.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Visual Acuity (VA) With Study Lenses, Collected by Eye	Day 1 Dispense; Day 2 Follow-up (ideally within 4 hours of awakening); Week 1 Follow-up/Exit	Visual acuity (VA) was assessed for each eye individually with study lenses in place 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 a lower logMAR value indicating better visual acuity. No formal hypothesis testing was planned.
