Bausch & Lomb Incorporated10 enrolled

Overview

Approximately 10 habitual soft contact lens wearing participants will be enrolled in this bilateral, randomized, double-masked (participant and investigator masked) repeated measures insertion study. All participants will be seen for a Screening/Dispensing Visit at which informed consent will be obtained and eligibility will be assessed. If participants satisfy all eligibility criteria and none of the exclusion criteria, participants will insert study lenses in random, successive order according to unique randomization schedules that will be provided to each Investigator.
