Calhoun Vision Light Adjustable Lens (LAL) in Subjects With Pre-Existing Corneal Astigmatism
CataractThe purpose is to evaluate the Calhoun Vision Light Adjustable Lens (LAL) and Light Delivery Device (LDD) for reducing astigmatism and improving uncorrected vision after implantation.
Prospective Study of an Investigational Toric Soft Contact Lens
MyopiaAstigmatism1 moreThe purpose of this study was to demonstrate substantial equivalence of an investigational toric soft contact lens to the commercially available Focus® DAILIES® Toric soft contact lens when worn in a daily wear, daily disposable mode for three months.
Wavefront Analyzes and Visual Performance of Three Multifocal Intra-ocular Lenses
CataractAstigmatismThe purpose of this study is to determine if differences in the design of multifocal intra-ocular lenses would mean different values of higher-order aberrations and different performance in objective parameters such as modulation transfer function.
Use of Toric Intraocular Lens to Neutralize Keratometric Astigmatism
CataractAstigmatismThe purpose of this study is to evaluate neutralization of keratometric astigmatism in patients with cataract and astigmatism higher than 1 diopter, with phaco surgery and the implantation of a toric intraocular lens.
Clinical Comparison of Two Silicone Hydrogel Toric Lenses in the US
AstigmatismThe purpose of this trial is to compare the performance of two different contact lenses for contact lens wearers with astigmatism.
Clinical Performance of Atypical Contact Lens Powers on Subjects With Astigmatism
AstigmatismThis study will evaluate the fitting characteristics and physiological response of two toric lenses manufactured by Vistakon.
Evaluation of Two Toric Soft Contact Lenses After Two Weeks of Wear
AstigmatismThe purpose of this study is to determine the relative performance of a new toric soft contact lens against a toric contact lens currently available in market, specifically with regards to the comfort and vision after two weeks of use.
Surgically Induced Astigmatism of Temporal Versus Nasal Clear Corneal Phacoemulsification
Surrgical Induced AstigmatismTo compare the short-term astigmatic outcomes of phacoemulsification cataract surgery and intraocular lens implantation using temporal versus nasal clear corneal incisions.
Evaluation of Orientation and Visual Acuity of Four Toric Soft Contact Lenses When Head is Tilted...
AstigmatismThe purpose of this study is to determine the relative performance of a new toric soft contact lens against three toric contact lens currently available in market, specifically with orientation and visual acuity when head is tilted at 90 degrees.
Evaluation of Outcomes Following LASIK Surgery Using CustomVue
MyopiaAstigmatism1 moreThe aim of the study was to evaluate visual outcomes, contrast sensitivity, glare and induced high order aberrations induced by the new CustomVue software use for wavefront-guided LASIK.
