The use of intraocular lenses was a great advance in visual recovery after cataract surgery. Although usually with good biocompatibility, some alterations in the intraocular lens material may occur after implantation. Polymethylmethacrylate was the first intraocular lens material to be used on a large scale and assumed to be inert and well-tolerated. We present a rare case of late opacification...

Background and Objective: Proper method and machine for corneal evaluation is an important factor in many anterior segment interventions. This study was performed to compare the mean keratometry (K) readings obtained with an IOL Master and Pentacam for intraocular lens power calculation in normal subjects with no history of refractive surgery. Materials and Methods: Mean K values were obtained ...

purpose: to compare the optical properties of hydrophilic and hydrophobic intraocular lenses (iols) containing uv-absorber and to determine their chemical composition. methods: optical properties of different foldable hydrophilic and hydrophobic as well as non-foldable hydrophobic polymethylmetacrylate (pmma) iols were evaluated in three powers of 15, 22 and 25 diopters. optical properties were...

PURPOSE To investigate the possible effect of aspherical or yellow tinted intraocular lens (IOL) on contrast sensitivity and blue-on-yellow perimetry. METHODS This prospective randomized bilateral double-masked clinical study included 52 patients with visually significant bilateral cataracts divided in two groups; 25 patients (50 eyes) received aspherical intraocular lens in one eye and spher...

This case report describes a case of Alagille syndrome with developing intraocular lens subluxation and rhegmatogenous retinal detachment 4 years after cataract surgery. A 15-year-old female patient with Alagille syndrome-associated cataracts in both eyes underwent phacoemulsification aspiration and intraocular lens implantation. Four years postoperative, intraocular lens subluxation developed ...

Objectives This study was designed to analyse the outcomes of secondary multifocal intraocular lens implantation in eyes with white cataracts. Methods White cataract patients undergoing secondary multifocal intraocular lens implantation between June 2014 and January 2015 were evaluated prospectively. As opposed to a conventional primary intraocular lens implantation for an optimal patient, th...

AIM To evaluate optimal standard intraocular lens power for Nepalese eye camp cataract patients. METHOD A retrospective case series of 5109 preoperative cataract patients. RESULTS Average axial length of 23.08 (SD 1.26). Average dioptre intraocular lens power 21.37 (3.04). CONCLUSION An increase in the intraocular lens power used at Nepalese eye camps from +21.0 to 22.5 dioptres would imp...
