PURPOSE To assess the pseudophakic anterior chamber depth (PP-ACD) or effective lens position (ELP) change after cataract surgery in patients with pseudoexfoliation syndrome (PEX). METHODS Consecutive eyes with PEX and cataract underwent standard phacoemulsification and were implanted with single-piece acrylic posterior chamber intraocular lenses (IOLs). Eyes with severe PEX and with axial le...

Recent reports have shown that SLG, one of two genes linked to the S locus of Brassica, encodes a secreted glycoprotein. We have used RNA gel blot analysis, genomic and cDNA clone analysis, expression in transgenic plants, and immunodetection to characterize SLG2, the SLG gene derived from the S2 haplotype. This haplotype belongs to the class II group of S haplotypes that exhibit a weak incompa...

PURPOSE Partial Coherence Interferometry (PCI) is a fast, noncontact method to calculate lens implant power for cataract surgery. It has been reported as a potentially more accurate method than ultrasound biometry. Prospective study of the refractive outcomes of a consecutive series of patients undergoing phacoemulsification surgery with preoperative biometry by both ultrasound A-scan and PCI. ...

OBJECTIVES To compare anterior chamber depth (ACD) changes after phacoemulsification surgery in patients with pseudoexfoliation syndrome (PEX) and normal patients using an anterior segment imaging method. Another aim of this study was to evaluate the effect of these changes on the accuracy of intraocular lens (IOL) power calculation and postoperative refraction. MATERIALS AND METHODS Twenty-t...

AIM To assess the refractive outcome of clear lensectomy combined with piggyback intraocular lens implantation in highly hyperopic patients. METHODS This case review included 19 eyes of 10 patients with high hyperopia and axial length less than 21mm. Intraocular lens power was calculated for emmetropia using the Holladay II formula in 17 eyes, and SRK/T formula in 2 eyes following clear lens ...

purpose: to evaluate residual refractive errors after cataract surgery and its determinant factors at farabi eye hospital, tehran. methods: simple random sampling was done among cataract surgery scheduled patients over a 4 year period (2003-2006). exclusion criteria were uveitis, previous intraocular surgery and ocular trauma. after applying the exclusion criteria, 423 patients were studied. le...

We have studied diversity in Arabidopsis lyrata of sequences orthologous to the ARK3 gene of A. thaliana. Our main goal was to test for recombination in the S-locus region. In A. thaliana, the single-copy ARK3 gene is closely linked to the non-functional copies of the self-incompatibility loci, and the ortholog in A. lyrata (a self-incompatible species) is in the homologous genome region and is...

PURPOSE To analyze the accuracy of the Holladay 2 formula, which has been proposed as an improvement over the original Holladay formula. METHODS This retrospective analysis comprised 317 eyes operated on by 1 surgeon using 1 technique and 1 intraocular lens style in a specialty practice. Because the Holladay 2 formula has yet to be published, its accuracy can only be analyzed using the commer...

OBJECTIVE The study aimed to review pediatric intraocular lens (IOL) implantations performed in the authors' institution for the past 7 years. STUDY DESIGN The study design was a retrospective chart review. PARTICIPANTS All children who underwent IOL placement between January 1, 1989, and January 31, 1996, at ages 2 to 16 years were studied. Follow-up was a minimum of 6 months up to 4 years...
