Divergent contrast sensitivity findings have been reported in patients with intraocular lens implants. In this study, contrast sensitivity to stationary sine-wave gratings of six spatial frequencies from 0.5 to 22.8 cycles/degree was measured psychophysically in 13 patients with posterior chamber intraocular lens implants and in 10 controls. Corrected visual acuity was 0.7 to 1.0 in the intraoc...

A woman presented with a painful eye 6 weeks after cataract extraction and intraocular lens implantation. In the past she had had a sector iridectomy for iris bombé caused by chronic anterior uveitis. On examination the three central corneal sutures were absent, whilst the medial and lateral sutures had broken and were protruding from the section. The eye was quiet and the section intact. Combi...

We report three patients with deposition of pseudoexfoliation (PXF) material on intraocular lens years after uneventful cataract surgery. PXF was not present before the cataract surgery. The PXF material was found on the anterior surface of the intraocular lens in the first patient and on the posterior surface as well in the other two patients. All the patients had a polymethylmethacrylate intr...

Introduction: We report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual outcomes in eyes with implantable collamer lens-induced cataract and astigmatism. Case presentation: A 53-year-old woman had undergone toric implan...

PURPOSE To describe the use of argon laser iridoplasty following implantation of a multifocal intraocular lens (IOL) to improve visual function. METHODS Argon laser spots of 500-mW power, 500-μm spot diameter, and 500-ms duration were placed in the midperipheral iris in the area in which the iris was encroaching on the IOL. RESULTS Argon laser iridoplasty provided statistically significant ...

OBJECTIVE AND METHOD To describe a surgical technique that enables diffractive lenses with open-loop haptics to be centered on the chosen optical axis. To perform this, the desired axis must initially be marked on the cornea, the rhexis must be aligned with this, and once the intraocular lens (IOL) is implanted in the capsular bag, it is aligned by intracapsular rotation to match the central ri...

PURPOSE To compare higher order aberrations (HOA) in AcrySof SN60AT and Acrysof IQ SN60WF intraocular lenses (IOLs) and natural crystalline lenses in an age-matched population. METHODS Sixty-nine eyes of 55 patients were examined. Group I included AcrySof spheric lenses, group II AcrySof aspheric lenses, and group III included patients with the natural crystalline lens. The HOA data were obta...
