Three-year follow-up of posterior chamber phakic intraocular lens implantation for high myopia

Abstract

Objective To investigate long-term efficacy and safety ofa posterior chamber phakic intraocular lens (PCPIOL) implantation for high myopia. Methods A consecutive group of 66 eyes in 41 patients with -15.12± 3.93 diopters (D) of myopia was implanted with the ICL PCPIOL (STAAR), and was examined preoperatively and 1, 2, 3 years postoperatively. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, intraocular pressure, and complications were evaluated. Results The implantation was successful in all of 66 eyes. Compared with preoperative data, UCVA, BCVA, and spherical equivalent (SE) were improved significantly. At 3-year postoperatively, UCVA in 86% eyes was 0.5 or better, in 43% was 0.8 or better; No loss of BCVA was found, 11% gained 1 line, and 68% gained 2 lines or more; SE in 96%, 57% eyes was within ± 1.00 D, ± 0.50D of attempted, respectively. At 1-, 2-, 3-year follow-up, the corneal endothelial loss was 9.26%, 12.84%, 18.54%, respectively. No severe complications occurred expect 1macular hemorrhage due to CNV. Conclusions At 3-year follow-up, the implantation of the PCPIOL proved to be safe and effective for the correction of myopia in phakic eyes.
