Abstract

We evaluated prospectively the effect of capsular opening larger than the optic diameter of intraocular lens(IOL) on visual outcome, change of refrectory power and postoperative complication in cataract surgery. Cataract surgery was performed to 55 patients using 5.75mm temporal corneal incision, continuous curvilinear capsulorhexis(CCC), phacoemulsification, implantation of polymethylmethacrylate(PMMA) posterior chamber IOL with 5.5mm of optic and 12.5mm of total length into the capsular bag, and one shoelace suture. The size of CC was 6.5mm in diameter, slightly larger than that of IOL optics. Uncorrected visual acuity 20/40 or better was obtained in 80% of eyes one day after operation. The change of sperical equivalent from postoperative one day to one week, one week to two months and two months to four months was -0.22+/-0.59(average+/-S.D.) diopters, +0.07+/-0.37 diopters and -0.01+/-0.13 diopters in average respectively. There was no decentration or tilt of IOL, posterior capsular opacity, and contraction of capsular opening smaller than 5mm inducing visual disturbance at postoperative 4 months. In conclusion, the technique of using CCC larger than the IOL optic can be a safe and useful in patients with posterior segment disease.
