Active clinical trials for "Myopia"

Two week, Open Label, randomized, bilateral, crossover, 1 week of daily wear in each combination (lens / disinfecting cleaning system).

This study is a masked, multi-center, daily wear, monthly replacement, bilateral, randomized, lens blocked (subjects remain in the same lens brand throughout the study) concurrent control study enrolling up to 90 subjects with a study duration of approximately three months. Subjects will be randomized into the study contact lenses in a two to one (2:1) ratio of fanfilcon A lens (test) to enfilcon A lens (control).

The objective of the study is to compare the overall subjective comfort profile over 8 hours of lens wear in two groups of habitual soft contact lens wearers (daily disposable hydrogel lenses and frequent replacement lenses) when refitted in to somofilcon A lenses.

The purpose of the study is to compare the results of PRKK surgery when using wavefront-guided excimer laser treatment compared to wavefront optimized excimer laser treatment in patients with nearsightedness with and without astigmatism

This is a continuation study for subjects who were previously fit with test or control lenses; all will stop wearing their study lenses assigned in the previous study and will start to wear an FDA-approved marketed spherical soft contact lens.

The purpose of this study was to evaluate the reduction of contact lens-related dryness symptoms when symptomatic weekly/monthly contact lens wearers were switched to DAILIES® AquaComfort Plus® lenses for a two-week period using composite scores on the Contact Lens Dry Eye Questionnaire (CLDEQ).

The purpose of this study was to compare the subjective performance of DAILIES TOTAL1® daily disposable contact lenses to that of 1-DAY ACUVUE® TruEye® daily disposable contact lenses.

This was be a randomized, contralateral, double-masked, dispensing study comparing the Study test lens against the control lens over one month of lens wear. The study results were not used for design validation of test lens.

The aim of this dispensing study is to evaluate the clinical performance of existing wearers of Avaira sphere lenses following a refit with Clariti Elite sphere over 4 weeks of daily wear.

The purpose of this study was to compare visual performance measures between two multifocal contact lenses on presbyopic wearers.
