Abstract
Purpose: This study reports the results of visual acuity, the efficiency and rotational stability of intraocular lens (IOL) after cataract surgery with a toric IOL implantation in the patients with regular astigmatism. Method: In this single-hospital retrospective study, 31 cataract patients (35 eyes) who had received phacoemulsification and a toric IOL implantation from October 2007 to May 2008 were evaluated. Both preoperative corneal cylinder and refractive cylinder powers were checked before surgery. The Phacoemul-sifications and toric IOL implantations were all performed by the same doctor. Outcomes of the visual acuity, refractive and keratometric astigmatism, and IOL rotation after operation were evaluated. Results: In the last follow-up, the IOL remained well centered in the capsular bag, and there were no intraoperative or postoperative complications. 31 eyes had the uncorrected visual acuity (UCVA) more than 0.5 (6/12). About the astigmatism, the mean refractive astigmatism reduced from 1.98D to 0.72D in the last follow-up. The IOL axis was rotated more than 4 degrees in 5 patients in the last follow-up but had maximum of 7 degrees only in 1 eye. Conclusion: The toric IOL axis deviation relate to the efficiency of astigmatism correction and visual outcome. Initial results of our study indicate that the toric IOL implantation can help patients getting effective correction of astigmatism and good visual quality.
