Clear lens extraction with intraocular lens implantation for hyperopia

Abstract

PURPOSE: To analyze the results of clear lens extraction (CLE) with posterior chamber intraocular lens (IOL) implantation to correct hyperopia. SETTING: Eye Research Center and Dr. Agarwal's Eye Hospital, Chennai, India. METHODS: This prospective study comprised 20 hyperopic eyes of 12 patients between 19 and 50 years who had CLE with posterior chamber IOL implantation. Five patients had peripheral iridectomy during CLE as the angles were occludable. RESULTS: The mean hyperopic spherical equivalent refraction was +6.66 diopters (D) +/- 2.17 (SD) (range +4.75 to +13.00 D). The IOL power was calculated using the Holladay 2 formula. The mean follow-up was 16.96 months (range 6 to 35 months). The mean postoperative uncorrected visual acuity was 0.45 +/- 0.25 (range 0.10 to 1.00), a mean improvement of 3 Snellen lines from preoperatively. The mean postoperative best corrected visual acuity (BCVA) was 0.63 +/- 0.30, a mean improvement of 1 Snellen line. Three patients gained 2 lines of BCVA and 2 patients, 1 line. One patient lost 1 line of BCVA. Seventy percent of patients were within +/-0.50 D of the intended refraction. CONCLUSION: The results indicate that CLE with posterior chamber IOL implantation is safe, predictable, and effective.
