Study Overview
Brief Summary
The objective of the study was to compare the lens performance of two daily disposable multifocal contact lenses.
Detailed Description
This was a prospective, randomized, participant-masked, crossover, bilateral dispensing study. Each lens type was worn for approximately 3-4 weeks: the lens prescription of each lens type was optimized after a 3-8 days wearing experience, then participants began a 2 week (14-21 day) wear period.

- •Self-reported as pregnant, lactating or planning a pregnancy at the time of enrolment;
- •Had undergone refractive error surgery or interocular surgery.

Outcomes
Primary Outcomes
Lens Handling for Removal
Time Frame: 2 Weeks
Subjective rating for ease of removal of the study lenses on a 0-100 scale, where 0=Very difficult and 100=Very easy. Collected once at the end of 2 weeks of wear.
