Comparison of Clinical Outcomes between Different IOL Sizes after Microincisional Cataract Surgery

Purpose: To compare clinical outcomes between different IOL sizes after microincisional cataract surgery. Methods: Retrospective chart review was done in 68 eyes of 68 patients who underwent phacoemulsification and implantation with two different-sized aspheric IOLs (AKREOS MI60 Bausch & Lomb, Inc., Rochester, NY). The patients were divided into 2 groups: group I consisted of 38 eyes between 15.5-22.0 diopter (D) (optic size 6.0 mm, overall size 10.7 mm), and group II consisted of 30 eyes between 22.5-30.0 D (optic size 5.6 mm, overall size 10.5 mm). The best corrected visual acuity (BCVA), refractive error, and anterior chamber depth (ACD) were measured preoperatively and postoperatively and were compared between groups. Results: Postoperative 6 month BCVA was 0.08 ± 0.10 D in group I and 0.07 ± 0.11 D in group II. During the same period, the spherical equivalent was -0.32 ± 0.65 D in group I and -0.16 ± 0.59 D in group II (p > 0.05). There were no significant differences in ACD or refractive error during the postoperative period (p > 0.05). Conclusions: Comparison of postoperative visual acuity and spherical equivalent between different sizes of Akreos MI-60™ IOLs showed no differences. J Korean Ophthalmol Soc 2011;52(11):1281-1285
