Filter by:This is a study to compare visual outcomes of subjects bilaterally implanted w/ReSTOR to subjects bilaterally implanted with the Tecnis Multifocal Intraocular Lens (IOL) or Acri.LISA IOL
The purpose of this study is to evaluate the visual outcomes and patient satisfaction after bilateral implantation of the aspheric ReSTOR multifocal intraocular lens (IOL) and compare it to a historical control group of patients implanted bilaterally with the spherical ReSTOR multifocal
A prospective evaluation of the visual parameters in a series of patients bilaterally implanted with AcrySof ReSTOR +3 Intraocular Lens (IOL).
This is a Randomized Controlled Trial to study the role of Capsular Tension Ring in patients with Retinitis Pigmentosa
Purpose: The aim of this study was to compare the effect of ciliary body training as proposed by manufacturers of accommodating IOLs and patient motivation on the pseudoaccommodative ability with a standard intraocular lens (SA60AT). Setting: Department of Ophthalmology, Medical University of Vienna. Methods: This randomized, controlled, examiner-masked study comprised 80 eyes of 40 patients that underwent standard cataract surgery. Patients were randomly assigned to a "motivated" or "non-motivated" (control) group. In the motivated group, subjects were told to take part in a special protocol to improve their near-reading ability after cataract surgery and were instructed not to use near adds for at least 3 months. Follow-up examinations included best-corrected distance visual acuity (VA), distance-corrected near VA, best-corrected near VA, defocus curve and reading speed, as well as pilocarpine-, cyclopentolate- and nearpoint-induced IOL shift assessed with partial coherence interferometry.
A comparison of the ability of DisCoVisc to that of other ophthalmic viscosurgical devices (OVDs) (DuoVisc, Healon5 or Amvisc PLUS) regarding endothelial protection and anterior chamber space maintenance during non-eventful cataract surgery.
There have been numerous studies comparing various ACD measurements in phakic eyes,while researches comparing ACD in pseudophakic eyes are less extensive. With the recent popularity of presbyopia correction, measuring the ACD will facilitate differentiating pseudophakic accommodation from pseudoaccommodation. It is thus mandatory to verify the accuracy of ACD measurement of these devices since the innovation of various IOLs in the recent decade makes this task more complicated. In this study, we will assess the limitations of using Pentacam for ACD measurement in pseudophakic eyes and compare Pentacam measurement with IOLMaster and A-scan measurements.
An assessment of the surgical performance of DisCoVisc compared to Healon5 during cataract surgery with intraocular lens implantation where miotic/small pupils or intraoperative Floppy Iris Syndrome exists.
To determine what effect a blue light filtering Intraocular Lens (IOL) has on macular pigment levels.
The objective of this study is to prospectively evaluate the visual parameters in a series of patients after phacoemulsification cataract surgery in a series of patients bilaterally implanted with the AcrySof® ReSTOR® Aspheric +3.0 Intraocular Lens (IOL).
