Filter by:1. To determine if the effect of near-addition lenses (bifocals) is more prominent for children with high myopia progression. 2. To study how different subject characteristics such as age, gender, baseline degree of myopia, baseline near phoria and baseline lag of accommodation affect the efficacy of bifocal lens wear in myopic children. 3. To investigate the effect of incorporating near base-in prisms along with the near-addition lenses (prismatic bifocals) on myopia progression in myopic children.
Evaluation of the clinical performance of a novel Bausch & Lomb daily disposable contact lens when compared to the currently marketed Bausch & Lomb SofLens® daily disposable contact lenses and the currently marketed Johnson and Johnson 1-Day Acuvue Moist contact lenses when worn by adapted soft contact lens wearers on a daily disposable basis.
The purpose of this combined retrospective and prospective chart review analysis is to investigate the safety, efficacy, and predictability obtained via Laser-Assisted In Situ Keratomileusis (LASIK) and Advanced Surface Ablation (ASA) over a wide range of refractive errors The working hypothesis is that there will be no difference in clinical outcomes between patients treated with LASIK or ASA.
The objective of this study is to evaluate the clinical performance of two daily disposable contact lenses.
Glaucoma is presumed to be an axonal disease which starts at the lamina cribrosa. This assumption has led to the monitoring of the retinal nerve fiber layer thickness for the diagnosis and monitoring of progression of glaucoma. However, varying disc size, myopia and tilted discs affect the thickness of the retinal nerve fiber layer. This study aims to ascertain the ration of the retinal nerve fiber layer against full retina as a predictor of glaucoma diagnosis and progression.
The purpose of this study was to demonstrate that current successful fulltime daily wear soft contact lens wearers using competitive multi-purpose solutions will note improved comfort when using OPTI-FREE RepleniSH®.
Comparison of LASIK outcomes using 3 different lasers and a total of 5 different treatment platforms.
The purpose of this study is to evaluate the safety and effectiveness of the Bausch & Lomb Technolas 217z laser with the investigational Zyoptix Aspheric Algorithm when used for LASIK treatment of myopia and myopic astigmatism.
To evaluate the wearing satisfaction of a new design of the PureVision soft contact lenses.
The purpose of this study is to establish the substantial equivalence of the HDS HI 1.54™ to the paflufocon C material control lenses to correct myopia and hyperopia with and without astigmatism. The purpose of the study is to profile the outcome endpoints and the patient acceptance of this Class II medical device.
