Acrylic toric intraocular lens implantation: A single center experience concerning clinical outcomes and postoperative rotation

Abstract

Purpose: To present clinical results of toric intraocular lens (IOL) implantation for preexisting astigmatism correction and determine the time of any postoperative rotation. Patients and methods: Twenty-nine eyes of 19 patients underwent uncomplicated phaco-emulsification and were implanted with an Acrysof © toric IOL. Uncorrected visual acuity, residual astigmatism, and postoperative rotation of the IOL were estimated one and six months after the operation. Results: Uncorrected visual acuity was ≥ 0.5 in 26 of 29 eyes (89.7%) and ≥ 0.8 in 19 of 29 patients (65.5%). The mean toric IOL axis rotation was 2.2 ± 1.5° (range 0.6-7.8°) one month postoperation and 2.7 ± 1.5° (range 0.9-8.4°) six months postoperation. Conclusion: Implantation of one-piece hydrophobic acrylic toric IOLs appears to have acceptable stability, which encourages visual outcome and emerges as an attractive alternative for correction of refractive astigmatism. © 2010 Tsinopoulos et al, publisher and licensee Dove Medical Press Ltd.
