Abstract

Purpose: To assess the efficacy and safety of a soft acrylic intraocular lens (IOL) in small incision cataract surgery.

Methods: Sixty-four eyes of 64 patients (mean age 71.0 +/- 7.7 [SD] years) who had phacoemulsification and implantation of a soft acrylic IOL were followed for 2 years.

Results: At day 1, 96.9% of patients had corrected visual acuity of 20/40 or better, and 50.0% had 20/20 or better. At 2 years postoperatively, 100% had 20/40 or better, and 86.3% had 20/20. Surgically induced keratometric cylinder remained quite stable throughout the 2 year follow-up period, with axis-based astigmatism of +/- 0.3 diopters. Flare intensity measured with the laser flare-cell meter was less than that with other type of IOLs measured, including poly(methyl methacrylate) and silicone. Neodymium:YAG laser capsulotomy was performed in seven cases (11.1%). without causing damage to the optic. No other postoperative complications were encountered.

Conclusion: Soft acrylic IOLs have clinically apparent advantages in small incision cataract surgery.
