Clinical Assessment of Two Daily Wear Reusable Soft Silicone Hydrogel Contact Lenses

Not Applicable

Completed

• Conditions: Refractive Errors

• Registration Number: NCT05056987
• Lead Sponsor: Alcon Research

Brief Summary

The overall objective of this clinical study is to describe the clinical performance of the TOTAL30® soft contact lens compared to the ACUVUE® OASYS® with HYDRACLEAR PLUS (AOHP) soft contact lens in a daily wear modality.

Detailed Description

Subjects will be expected to attend 3 visits and wear the study contact lenses at least 5 days per week and at least 8 hours per day. On Visits 2 and 3, subjects will be expected to wear the study lenses at least 6 hours prior to the study visit. The expected total duration of subject participation in the study will be approximately 1.5 months. This study will be conducted in the United Kingdom (UK).

Primary Outcome Measures

Name	Time	Method
Distance VA (logMAR) With Study Lenses	Dispense (Day 0) and Follow-Up (Day 28 for TOTAL30, Day 14 for AOHP) (each wear period)	Distance visual acuity (VA) was assessed for each eye individually with study lenses in place using letter charts. VA was measured in 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. The follow-up visit for TOTAL 30 occurred approximately 28 days after the baseline visit. The follow-up visit for AOHP occurred approximately 14 days after the baseline visit. No formal hypothesis was formulated for the primary effectiveness endpoint of distance VA; hence, no inferential testing was performed.
