Comparison of the optical image quality in the periphery of phakic and pseudophakic eyes.
PURPOSE The natural lens may provide some compensatory optical effect in the periphery. When it is substituted by an IOL during cataract surgery, the quality of the peripheral optics will be modified. We compared the peripheral image quality in the eyes of patients with one eye implanted with a monofocal IOL and the fellow eye still with the natural precataract lens. METHODS We used a scannin...
متن کاملQuality of Life in Pseudophakic Children Operated Both Eyes for Congenital and Developmental Cataract
Introduction: Pediatric cataracts contribute a very significant proportion of avoidable blindness in children. Despite the recent advances made in pediatric cataract management, many patients may not be satisfied with their quality of life (QOL). We conducted this study to evaluate the quality of life in pseudophakic children operated both eyes for congenital or development cataract. We also as...
متن کاملAutomatic visual quality assessment in optical fundus images
A method for automatically assessing the quality of retinal images is presented. It is based on the idea that images of good quality possess some common features that should help define a model of what a good ophthalmic image is. The proposed features are the histogram of the edge magnitude distribution in the image as well as the local histograms of pixel gray-scale values. Histogram matching ...
متن کاملAssessment of Optical Quality at Different Contrast Levels in Pseudophakic Eyes.
Purpose. To assess visual function using Optical Quality Analysis System (OQAS) at varying levels of contrast in pseudophakic eyes. Methods. The study included patients admitted to Seoul St. Mary's Hospital between January and February 2012: 143 pseudophakic eyes with one of five intraocular lens types, examined 2-6 months after cataract surgery, and 93 normal eyes (enhanced visual acuity (VA) ...
متن کاملPars Plana Vitrectomy and Silicone Oil Injection in Phakic and Pseudophakic Eyes; Corneal Endothelial Changes
PURPOSE To evaluate the effect of silicone oil (SO) on the corneal endothelium in SO filled phakic and pseudophakic vitrectomizied eyes. METHODS This prospective comparative consecutive case-control study evaluated the corneal endothelial characteristics of 64 SO filled vitrectomizied eyes (case group) as compared to 46 vitrectomizied eyes without SO injection (control group). Endothelial cel...
