2-YEAR CLINICAL-STUDY OF A SOFT ACRYLIC INTRAOCULAR-LENS

Purpose: To assess the efficacy and safety of a soft acrylic intraocul ar lens (IOL) in small incision cataract surgery. Methods: Sixty-four eyes of 64 patients (mean age 71.0 +/- 7.7 [SD] years) who had phacoem ulsification and implantation of a soft acrylic IOL were followed for 2 years. Results: At day 1, 96.9% of patients had corrected visual acu ity of 20/40 or better, and 50.0% had 20/20 or better. At 2 years post operatively, 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 tha n that with other type of IOLs measured, including poly(methyl methacr ylate) and silicone. Neodymium:YAG laser capsulotomy was performed in seven cases (11.1%) without causing damage to the optic. No other post operative complications were encountered. Conclusion: Soft acrylic IOL s clinically apparent advantages in small incision cataract surgery.
