Active clinical trials for "Myopia"

The purpose of this study was to compare lens comfort on Day 30 for Air Optix® lenses cared for with OPTI-FREE® PureMoist® (OFPM) Multi Purpose Disinfecting Solution (MPDS) compared to Acuvue® Oasys® lenses cared for with habitual MPDS.

This is a one week 2x2 crossover study comparing delefilcon A with etafilcon A, with a primary hypothesis of comparing the handling of each lens. Additional secondary markers are measured looking at subjective comfort and vision of the lenses.

Phase I: Focus groups on different designs of adjustable glasses and standard glasses (August-September 2012) Phase II: Two-month randomized trial comparing four groups: (September 2012 - August 2013)

The purpose of this study is to evaluate the comfort of color contact lenses in a population of clear contact lens wearers who have an interest in wearing color contact lenses.

This was a prospective, case-control study investigating aqueous levels of VEGF and PEDF in eyes with mCNV treated with IVB.

The Visual Pathfinder (LACE inc.) offers a non- invasive, patient- centered visual rehabilitation system based on an acoustic biofeedback. The investigators wanted to evaluate its usefulness in the improvement of visual function in visually impaired patients with high myopia.

This is a prospective, multi-center, subject-masked, bilateral wear, one month dispensing study comparing the clinical performance of the subjects' habitual comfilcon A sphere lens (control) following a refit with comfilcon A asphere lens (test). After the dispensing visit, subjects will return for follow-up evaluations after 2 weeks, and 1 month.

Two-month randomized trial comparing three groups.

This study will investigate performance criteria over one week of daily wear to determine if the Study Test contact lens performs equivalently to the comfilcon A contact lenses in terms of subjective ratings and of visual performance. The study test lens was not the final optical design and the study results were not used for the design validation.

The aim of this non-dispensing study is to evaluate the clinical performance of different hydrogel contact lens designs.
