Study Summary
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.
Primary Outcome
Immediately following lens removal, the right-eye worn lens for each participant was measured for surface refractive index on a Metricon M-2010 Prism Coupler. A new lens pair was worn for each wear time. Surface refractive index is a dimensionless ratio and has no units.
Interventions
- DEVICE Kalifon A
