LONG-TERM OUTCOME OF TRANSSCLERAL FOUR-POINT FIXATION OF AKREOS INTRAOCULAR LENS WITH CLOSED CONTINUOUS-LOOP SUTURE.

Abstract

Purpose: To report the long-term clinical outcomes of transscleral four-point fixation of Akreos intraocular lens using a closed continuous-loop suture technique.

Methods: This was a retrospective, multicenter, interventional case series. Primary outcome measures were best-corrected visual acuity, intraocular pressure, corneal endothelial cell density, and complications with a minimum of 1-year follow-up.

Results: One hundred and ninety-two eyes of 177 patients from two surgical hospital sites were identified. The mean best-corrected visual acuity improved from 0.88 ± 0.74 logarithm of the minimum angle of resolution (Snellen 20/152) preoperatively to 0.42 ± 0.52 logarithm of the minimum angle of resolution (Snellen 20/53) postoperatively ( P < 0.001). The mean preoperative intraocular pressure was 17.51 ± 8.67 mmHg, and the mean postoperative intraocular pressure at final follow-up was 15.08 ± 4.18 mmHg ( P = 0.001). The mean corneal endothelial cell density significantly reduced from 2,259 ± 729 cells/mm 2 to 2077 ± 659 cells/mm 2 , representing a cell loss of 5.73% ( P < 0.001). The intraocular lens was fixed well during follow-up. There were no intraoperative complications noted. Postoperative complications included transient ocular hypertension in 15 eyes (7.81%), hypotony in two eyes (1.04%), retinal detachment in one eye (0.52%), and macular edema in one eye (0.52%).

Conclusion: The transscleral four-point fixation Akreos intraocular lens using the closed continuous-loop suture technique was effective and safe with satisfactory visual acuity with a minimum of 1-year follow-up.
