Filter by:The purpose of this study is to obtain and assay human aqueous samples following pre-operative dosing with 0.1% Brimonidine Purite™ (pH 7.8) or with 0.15% Brimonidine Purite® (pH 7.2) from patients undergoing routine cataract surgery in order to evaluate the aqueous concentration of the two formulations.Study hypothesis: The aqueous humor concentration 45 minutes following dosing of 0.1% Brimonidine Purite™ (pH 7.8) is comparable with 0.15% Brimonidine Purite® (pH 7.2)
The purpose of this study is to evaluate the efficacy on quality of vision and dry eye signs and symptoms in patients undergoing cataract surgery using the ReZoom® multifocal IOL.
The purpose of this clinical trial is to determine if interventions within the nursing home to restore vision, or cope with visual loss, in residents with visual impairment result in improvement or less decline in mobility scores, and socialization scores, compared to residents with visual impairment in nursing homes with no such intervention. The investigators hypothesized that nursing home residents with visual loss who receive cataract surgery, or refractive correction, or low vision aids would have have better socialization scores and mobility scores at 6 months and 12 months compared to nursing home residents with visual impairment who are advised to seek services, but have no specific program.
The purpose of this study is to compare the clinical outcomes, safety and efficacy in patients randomized to receive either ketorolac or nepafanac following cataract surgery.
This study is a comparison of the quality of vision provided by AMO Tecnis Z9000 three-piece silicone posterior chamber intraocular lens and Alcon Laboratories MA60 three-piece acrylic posterior chamber intraocular lens.
Evaluate if the incidence of sub clinical CME can be significantly reduced by use of peri-operative Acular LS plus Pred Forte when compared with Pred Forte alone in normal cataract patients.
The primary purpose of this study is to evaluate whether interventions to improve vision in nursing home residents have an impact on residents' health-related quality of life. The interventions being evaluated are correction of refractive error (near-sightedness, far-sightedness, presbyopia) and cataract surgery.
Implantation of an intraocular lens is the gold standard in modern day cataract surgery. The appropriate lens power needed to achieve the desired refractive outcome can be calculated with a whole variety of formulas. To date, there has been no prospective study conducted to evaluate the accuracy of the IOL power calculation formulae commonly in use. It is well established that the frequently used IOL formulas do not show significant differences when used in eyes of average axial length (i.e. between 22mm and 25mm) and it is at the extremes of axial lengths where discrepancies arise. Our aim is to find the most appropriate formula(e) for these 'long' and 'short eyes' particularly in our population where there is a significant proportion of high myopes.
Evaluation of the aqueous concentrations of 2 topical NSAIDS as well as the PGE2 inhibition in human patients.
Purpose:To compare visual performance, total and high order wavefront aberrations (coma, spherical aberration and other terms) and contrast sensitivity in eyes implanted with one monofocal aspheric intraocular lens (IOL) and two spherical IOLs (SofPort AO, Soflex,AcrySof®IQ (40 eyes), AcrySof®Natural and AMO®Sensar)
