A recent investigation' has shown that the comea of the aphakic eye swells less than that of the normal fellow eye when fitted with identical hydrophilic lenses. This confirms previous clinical impressions and would suggest that a metabolic difference may exist between the corneas of the normal and the aphakic eye. The present investigation was therefore devised to assess certain aspects of the...

PURPOSE To measure corneal and total optical aberrations in the normal and treated eye of a unilateral aphakic patient to (1) cross-validate techniques in an eye in which corneal and total aberrations should be almost identical (aphakic eye) and (2) compare the interactions of corneal and internal aberrations in the normal eye with those in the aphakic eye. SETTING Instituto de Optica, Consej...

The authors evaluated the accuracy of topographic measurements with the laser tomographic scanner using a model eye. Diameter, depth, and shape at different axial lengths of four sample holes that simulated optic nerve heads in phakic and aphakic conditions were determined by confocal imaging. The computer-generated cross-section profiles of the simulated optic nerve heads corresponded well wit...

By using a small air bubble that fills about two thirds of the anterior chamber the erect image of the fundus of the aphakic human eye can be visualised clearly during vitrectomy, enabling the surgeon to operate without the need for vitrectomy lenses. The refractive power of the human aphakic eye is calculated here and the image site and size are presented.

AIMS To determine the differential effects of genetic polymorphism in CFH and ARMS2 on risk of age-related macular degeneration (AMD) between phakic vs. pseudophakic/aphakic eyes. METHODS 9,529 eyes of 4,918 participants from the Singapore Malay Eye Study and Singapore Indian Eye Study were analyzed. Participants had detailed eye examinations, including slit-lamp examinations and dilated fund...

purpose: to evaluate the efficacy and safety of primary aphakic artisan–verysise intraocular lens (iol) implantation during complicated cataract surgery. methods: the study is a retrospective analysis of 49 eyes that underwent primary aphakic artisan iol implantation for complicated cataract surgery. compiled data included demographic information, visual outcomes and complications. pre- and pos...

The influence of anomalous visual experience on the postnatal regulation of axial eye elongation was explored by raising newborn rhesus monkeys under different types of monocular and binocular deprivation and comparing their eye growth pattern with that of age-matched normal monkeys. Monocular manipulations included eyelid suture to eliminate pattern vision; continuous occlusion with an opaque ...
