Active clinical trials for "Hyperopia"

The study objective was to compare short-term clinical performance data of two soft spherical contact lenses.

To obtain subjective and objective feedback on the clinical performance of Biofinity lenses after at least two weeks daily wear in existing contact lens wearers compared with their habitual lenses.

The purpose of this study is to demonstrate non-inferiority of a new daily disposable multifocal contact lens in plus powers against the commercially available AIR OPTIX® AQUA MULTIFOCAL (AOAMF) lens in high contrast/high illumination (HC/HI) near visual acuity (VA).

The purpose of this study is to compare visual acuity between two daily disposable contact lenses.

The current study aims to systematically investigate the diurnal variation in the optical quality of soft contact lenses on eye throughout the day. Subject reported quality of vision will also be evaluated.

The purpose of this study is to compare the amount of coma as measured by aberrometry induced by two silicone hydrogel toric lenses in astigmatic participants.

To determine the ability of two topical Nonsteroidal Anti-inflammatory drops (Acular LS & Nevanac) to help control pain following Photorefractive Keratectomy (PRK).

To evaluate the clinical performance of an investigational silicone-hydrogel lens when worn on a daily wear modality over two weeks of lens wear.

By using a new software two consecutive laser treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment. This study will help us to answer 2 questions: How accurately this combined technique corrects distance and near vision Whether the correction is adequate to remove the complete need for supplementary near spectacles

Subjects with myopia, hyperopia and astigmatism are being randomized to be treated in one eye with a wavefront-guided excimer laser and their fellow eye treated with a wavefront-optimized excimer laser.
