Filter by:Approximately 126 subjects scheduled to undergo cataract surgery by phacoemulsification, will be randomized in an even allocation (1:1:1) to either Acuvail, Xibrom, or Nevanac. Subjects will be instructed to begin dosing the study medication in the operative eye the day before surgery and continue dosing on the day of surgery. Beginning one hour before surgery, 1 drop of study medication will be instilled by operating room staff approximately every 15 minutes for a total of 3 doses. At the designated time a paracentesis will be performed at the start of the cataract procedure and at least 0.15 cc of aqueous humor will be collected. The sample will be immediately stored on dry ice and shipped to a laboratory for analysis.
Given the availability of aspheric diffractive IOLs with varying negative spherical aberration it may be feasible, by selecting the best fit IOL, to minimize aberrations and thereby maximize visual performance.
Two very common aging-related diseases in older adults are Alzheimer's disease (AD) and cataracts. In elderly adults, these two diseases frequently occur in the same person. Although a cure for AD is currently unavailable, cataracts can be effectively treated with surgery in most people. The removal of cataracts has documented benefits for visual performance and for reducing accidents and falls. However, it has been the experience of the ophthalmologists, and others in the field, that patients, caregivers, and primary care doctors are reluctant to proceed with cataract surgery once an individual is given the diagnosis of AD. It is thought that cataract surgery will not improve the AD patient's quality of life, vision, and cognition. The investigators have designed this study to determine whether or not this is true.
The primary objective of this study is to evaluate, for the visual correction of aphakia, the safety and effectiveness of the Calhoun Vision Light Adjustable intraocular lens (LAL) and Light Delivery Device (LDD) in treating postoperative residual refractive error by providing a stable, targeted refractive adjustment of the LAL power and lock-in treatments with the LDD.
The purpose of this study is to determine if there is a difference on the penetration of betadine 5% when using lidocaine 2% jelly versus topical tetracaine 0.5% in topical cataract surgery. This will be assessed comparing bacterial colony count and species by taking swabs from the eye surface before and after the topical anesthesia has been administered.
The objective of this study is to evaluate postoperative visual function in patients implanted bilaterally with the ReSTOR Aspheric Intraocular Lens (IOL).
The objective of this study is to determine if an extension of bromfenac BID monotherapy is effective in the decreasing retinal thickening post cataract IOL placement surgery. No studies exist on how long to treat with an NSAID post cataract IOL placement surgery. Currently, NSAID therapy post IOL placement surgery is in conjunction with steroid treatment, lasting approximately 3 weeks. This study is designed to examine if there is benefit to extending NSAID monotherapy in regards to macular thickening and the incidence of CME.
A comparison of the ability of DisCoVisc to that of other Opthalmic Viscosurgical Devices (OVDs) (DuoVisc®, BioVisc®, Healon5®, or Amvisc PLUS) regarding endothelial protection and anterior chamber space maintenance during non-eventful cataract surgery.
Study evaluates the visual outcomes and patient satisfaction after implantation of a toric intraocular lens (IOL).
Bilateral evaluation of unilateral implantation of ReSTOR and contralateral monofocal or phakic eye.
