Clinical Study of a UV-Absorbing Acrylic Posterior Chamber Intraocular Lens
AphakiaThe purpose of this study is to assess the safety and efficacy of the HMY Model YA-60BB Intraocular Lens (IOL) when implanted in the posterior chamber of the human eye for the optical correction of aphakia following cataract extraction.
Infant Aphakia Treatment Study (IATS)
Congenital CataractThe primary purpose is to determine whether infants with a unilateral congenital cataract are more likely to develop better vision following cataract extraction surgery if they undergo primary implantation of an intraocular lens or if they are treated primarily with a contact lens. In addition, the study will compare the occurrence of postoperative complications and the degree of parental stress between the two treatments.
Visual Quality Following Aspheric Intraocular Lens (IOL) Implantation - a Comparative Clinical Study...
AphakiaCataractTo evaluate visual acuity and quality of vision in participants undergoing cataract surgery with a Hoya model 751 intra-ocular lens and to compare the visual results to the common monofocal lens in use.
Visual and Refractive Outcomes of The ClarVista HARMONI™ Modular Intraocular Lens System (HMIOL)...
CataractAphakiaThe purpose of this study was to evaluate visual and refractive outcomes with the use of the HARMONI™ Modular Intraocular Lens (HMIOL) System implantation, assembly, and optic exchange in subjects undergoing cataract surgery.
Evaluation of the Tecnis™ Multifocal and Crystalens™ Accommodating Intraocular Lenses
AphakiaThe purpose of this study is to compare the visual outcomes with bilateral implantation of Tecnis MF and Crystalens™ AO Aberration-free Accommodating intraocular lens (IOLs) 6 months after post cataract surgery.
Clareon Toric vs Eyhance Toric
CataractAphakiaThe primary purpose of this study is to compare the Clareon/Clareon Toric Intraocular Lenses (IOLs) to the Eyhance/Eyhance Toric IOLs in binocular Best Corrected Distance Visual Acuity (BCDVA) at 3 months postoperative.
Clinical Investigation of the AcrySof IQ Vivity Extended Vision Intraocular Lens (IOL)
AphakiaThe purpose of this study is to compare the visual disturbance profile of an intraocular lens (IOL) using nondiffractive optics, the VIVITY IOL, to two diffractive IOLs in subjects requiring bilateral cataract surgery. IOLs are implantable medical devices intended for long-term use over the lifetime of the cataract patient.
Post Approval Study of the AcrySof® IQ ReSTOR® Toric IOLs
AphakiaPresbyopia1 moreThis is a prospective, multicenter, post-approval active surveillance study. The purpose of this study is to report the rate of post-surgical intraocular inflammation (based upon a specified case definition) reported within a 180-day post-surgical period following attempted implantation of an ACRYSOF IQ RESTOR Toric or ACRYSOF IQ RESTOR IOL in the US.
Co-Axial Micro-Incision Versus Co-Axial Small Incision Cataract Surgery Using the Stellaris Enhancement...
CataractAphakiaThe objective of this study is to test the hypothesis that the time to reach a stable refraction is significantly shorter in eyes operated with the 1.8 mm coaxial microincision compared to eyes operated with the 2.75 mm standard incision using the Stellaris Vision Enhancement System.
Real-World Study of Vivity Intraocular Lenses (IOLs)
AphakiaPresbyopiaThe primary objective of this clinical study is to assess the clinical performance of the AcrySof IQ Vivity Extended Vision IOL in a Chinese population.
