Retinal Imaging through Phakic Iris-Claw IOL.

2014

AbstractBackground: Phakic anterior chamber iris-fixated IOL (PIOL) are established for the correction of high myopia. These patients require attention to macular pathologies. This study was to evaluate the quality of imaging through the PIOLs. Methods: 54 eyes of 31 myopic and hyperopic patients with Verisyse®, Verisyse toric®, and Veriflex® phakic iris-fixated IOL were included. Mean preoperative refraction was −11.0 D and +5.7 D, respectively; mean follow-up time was 7.4 years (5–11 years). A matched control group was formed without PIOL implantation. OCT scans were performed and evaluated qualitatively and quantitatively. Results: In 52 eyes of 31 patients (96%), a 3D-OCT image and fund…

Contrast sensitivity after implantation of toric iris-claw lenses in phakic eyes.

2004

Abstract Purpose: To evaluate the change in contrast sensitivity after implantation of the Verisyse toric phakic intraocular lens (IOL) (AMO) for the correction of myopia with astigmatism. Setting: Department of Ophthalmology, Johannes Gutenberg-University, Mainz, Germany. Methods: Eighteen eyes had implantation of an iris-supported toric phakic IOL to correct myopia with astigmatism. The mean preoperative spherical equivalent was −12.65 diopters ± 3.6 (SD). The contrast sensitivity with best spectacle correction was determined before surgery and 3 months after surgery using the CSV-1000 HGT instrument (Vector Vision Inc.). Results: Three months after IOL implantation, the mean contrast sen…

Modulation transfer function: Rigid versus foldable phakic intraocular lenses

2008

Purpose To study in a standard eye model the changes in modulation transfer function (MTF) of a monofocal intraocular lens (IOL) when a phakic IOL (pIOL) is placed in the anterior chamber, compare the MTFs of the rigid Artisan pIOL and foldable Artiflex pIOL, and evaluate the temporal evolution of the MTF of the foldable pIOL after the mechanical stress the pIOL undergoes when injected. Setting Fundacion Oftalmologica del Mediterraneo, Valencia, Spain. Methods The MTF values of the IOLs were calculated from the cross-line spread function recorded with the Opal Vector System. The measurements were taken using an eye model following the British and EN-ISO standards with 2.0 mm, 3.0 mm, 4.0 mm…
