Evaluating the Success of Habitual Multifocal Wearers When Refit With a New Lens Design

This was a prospective, crossover, bilateral daily wear, and subject masked dispensing study. The habitual contact lenses were not optimized. There was no randomization of the study lenses, participants wore the control lenses for the first wear period and the test for the second wear period. Participants wore each study lens for 3-7 days and then attend a prescription optimization visit. After this optimization visit, they wore each study lens for a 2-week period. During the 2-week wear period, participants recorded their subjective lens-wear experience remotely.
