purpose: to evaluate the ability to predict visual outcome after penetrating keratoplasty (pkp) in patients with pseudophakic or aphakic corneal edema (pce or ace). methods: medical records of 34 patients (34 eyes) who underwent pkp for pce or ace during 1994-2004 in ahvaz were retrospectively analyzed for variables in the history and ocular examination before pkp and visual outcome after pkp. ...

PURPOSE To evaluate the efficacy, predictability, stability, safety, and complications of secondary anterior iris fixation of the Artisan iris-fixated intraocular lens (IOL) to correct aphakia in eyes without sufficient capsule support. SETTING Department of Ophthalmology, Jinling Hospital, School of Medicine, Nanjing University, Nanjing, China. DESIGN Cohort study. METHODS Eyes having im...

Endothelial keratoplasty (EK) is the most exciting recent development in corneal transplantation. It has experienced surprisingly rapid growth in a very short period of time. One of the indications for EK is pseudophakic bullous keratopathy. However, concomitant intraocular lens (IOL) exchange, if indicated, may prove challenging. Some surgeons routinely perform IOL exchange with a scleral-fixa...

We prospectively studied for three years the optical correction by contact lenses of 83 aphakic infants (141 eyes) who generally also had systemic and other ocular anomalies: 85% of the patients tolerated the lens wear for the whole study period. Complications occurred in 46 eyes and led to cessation of lens wear in two cases. Ten patients abandoned the lenses for other reasons. Thirty-four eye...

INTRODUCTION Selective laser trabeculoplasty is a treatment option to lower intraocular pressure in patients with glaucoma. It has been proven to work in adults. We describe two pediatric patients with glaucoma who responded well to selective laser trabeculoplasty. CASE PRESENTATIONS Two patients with pediatric glaucoma underwent selective laser trabeculoplasty. Patient 1 was a nine-year-old ...

THiE problem of correcting the refractive error of an aphakic eye other than by prescribing the cumbersome cataract lenses still remains open, in spite of the excellent work done in this field by Ridley, and all its modifications. In search of a method which might combine greater safety for the patient with a simpler operative technique, an operation has been devised which consists in implantin...

The environment and lifestyle of a species are known to exert selective pressure on the visual system, often demonstrating a tight link between visual morphology and ecology. Many studies have predicted the visual requirements of a species by examining the anatomical features of the eye. However, among the vast number of studies on visual specializations in aquatic animals, only a few have focu...
