Early clinical outcome with a new monofocal microincision intraocular lens.

Abstract

The purpose of this study wasto evaluate the early visual and refractive outcomes of a new aspheric monofocal microincision intraocular lens (IOL). This retrospective case series included eyes of patients who underwent implantation of a microincision IOL following 1.8mm manual coaxial microincision cataract surgery and who attended regular postoperative follow-up visits on the first week and first, third, and sixth months. The postoperative uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction and predictability, intraoperative and postoperative complications, posterior capsule opacification (PCO), IOL centration, and surgically induced astigmatism (SIA) were evaluated. Sixty-three eyes of 38 patients ranging in age from 51 to 86 were included in the study. The mean preoperative BCVA was 0.52±0.42 logMAR. At the postoperative sixth month, the mean postoperative UCVA and BCVA were 0.12±0.11 and 0.01±0.03 logMAR, respectively. The mean postoperative spherical equivalent refraction (SER) was -0.30±0.49 D. The SER was within±1.00 D of the attempted correction in 95.2% of the eyes. The mean SIA measured with vector analysis was 0.45±0.28 D. Mild PCO was observed in 9 eyes (14.7%) with none requiring Nd:Yag laser capsulotomy. On centration analysis, the IOL was found to be 0.26mm on average to the supero-nasal position. The aspheric microincision IOL was safely implanted and provided satisfactory visual and refractive outcomes in the early postoperative period.
