Filter by:This is a single-masked, two-arm, parallel-group, randomized-controlled, dispensing clinical trial to evaluate the visual performance.
This is a bilateral, dispensing, randomized, controlled, subject-masked, 2-arm parallel study to evaluate safety and efficacy
This will be a 5-visit, randomized, partially single-masked, bilateral wear, dispensing, 2-treatment × 2-period crossover study with spectacle-wear washout and wash-in periods.
The study is a bilateral, single-masked, single-arm, 4-visit dispensing study evaluating the visual performance of the study lenses.
This will be a single centre pilot study to evaluate appearance of the Meibomian glands.
This is a single-masked, bilateral, controlled, randomized, 2x2 crossover, non-dispensing clinical trial to characterize the effects of an HEV-Blocker on several measures of visual function in a presbyopic population.
The study is a bilateral, single-masked, single-arm, 4-visit dispensing study. There will be one study treatment, with the subject being dispensed lenses for 6 to 8 days, then lens power will be optimized (if necessary) and dispensed for a further 2 weeks to assess the clinical performance of investigational multifocal toric contact lenses.
This study is a 2-phase adaptive approach utilizing a 2×2 crossover design. The study lenses will be worn in a bilateral fashion for a period of approximately 1-week each.
This is a single-masked, 2×3 crossover, randomized controlled, dispensing clinical trial to evaluate the visual performance (logMAR) and subjective vision responses of the Test Lens.
This is a bilateral, 2-week dispensing, randomized, controlled, subject-masked, 2×2 crossover study to evaluate the clinical performance of prototype contact lenses with experimental UV/HEV-blocker.
