Clinical Comparison of DDT2 Contact Lens and a Daily Disposable Contact Lens - Study 2

Not Applicable

Completed

• Conditions: Refractive Error; Myopia
• Interventions: Device: Verofilcon A contact lenses; Device: Somofilcon A contact lenses

• Registration Number: NCT03888482
• Lead Sponsor: Alcon Research

Brief Summary

The purpose of this study was to evaluate visual acuity at distance when wearing DDT2 contact lenses compared to Clariti contact lenses.

Detailed Description

Subjects were expected to attend 3 study visits and wear the DDT2 and Clariti study lenses in a crossover design for approximately 14 - 20 days (7 - 10 days for each product).

Primary Outcome Measures

Name	Time	Method
Least Squares Mean Distance Visual Acuity With Study Lenses	Day 8, each product	Visual acuity was assessed and collected for each eye separately using logarithmic of the Minimum Angle of Resolution (logMAR) charts. A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal visual acuity), with a negative value denoting better than 20/20 visual acuity.
