PURPOSE To evaluate the indications, visual outcomes, and complication rate after implantation of a posterior chamber iris-claw aphakic intraocular lens (IOL). SETTING Department of Ophthalmology, University Medicine Charité Berlin, Berlin, Germany. DESIGN Retrospective case series. METHODS Eyes without adequate capsule support had posterior chamber iris-claw aphakic IOL implantation (Ver...

Introduction Blue light is a part of the spectrum with the highest energy content, which can reach the retina. The damage that it can cause to the retina is called photochemical or blue-light retinal injury. For the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (W.m-2.sr-1) seems to be ...

AIMS To evaluate the outcome of filtering procedures supplemented with mitomycin C in children with glaucoma. METHODS All patients aged 17 or younger with glaucoma who underwent filtering surgery supplemented with mitomycin C at a tertiary care centre (n = 21) during a 5 year interval (1992 and 1996) were included. One eye for each patient was entered into the analysis. The postoperative intr...

PURPOSE To evaluate whether very early treatment for congenital unilateral cataract results in better long-term functional outcomes, grating acuity, contrast sensitivity, recognition acuity, and random-dot stereoacuity were evaluated in two groups of children. METHODS Grating acuity and contrast sensitivity data were obtained with standard forced-choice protocols. Stereoacuity data were obtai...

BACKGROUND New strategies have been developed for surgical treatment of high myopia. Recently, implantation of minus power posterior chamber intraocular lenses (IOL) into phakic eyes has been introduced. METHODS We report a 37 year-old female patient who developed bilateral anterior subcapsular cataract 7 years after minus-power, top hat-style silicone posterior chamber IOL implantation in Ru...

PURPOSE To evaluate visual outcomes, eye movement abnormalities, and postoperative complications after secondary posterior chamber intraocular lens (IOL) implantation in aphakic children who had initial LAC correction. METHODS A retrospective study was carried out on 53 patients (94 eyes). Following aphakic surgery and LAC correction the patients received secondary IOL implantation in the pos...

While it is known that scleral search coils-measuring the rotation of the eye globe--and modern, video based eye trackers-tracking the center of the pupil and the corneal reflection (CR)--produce signals with different properties, the mechanisms behind the differences are less investigated. We measure how the size of the pupil affects the eye-tracker signal recorded during saccades with a commo...

A elderly male presented with painful loss of vision in the left eye for 20 days expulsion intra-ocular content following a blunt trauma. The best corrected visual acuity was counting fingers close to face (CF-CF). Slit lamp examination revealed ciliary tissue prolapse gaping incision scar along posterior synechia, iris pigments, vitreous Anterior chamber, cells and flare. Patients aphakic had ...

Neonatal aphakia is associated with retardation of the axial elongation of the neonatal eye. In contrast, form deprivation increases axial elongation, an effect that has been associated with decreased retinal dopamine metabolism. The present investigation was conducted to test the hypothesis that neonatal aphakia induces an effect on the levels of retinal dopamine opposite to form deprivation. ...
