Results of Posterior Chamber Lens Implantation for Correction of Myopia

Abstract

Purpose: To evaluate the results of posterior chamber phakic intraocular lens implantation in myopic patients. Material and Method: Posterior chamber phakic intraocular lens (STAAR ICL) implantation was performed in 58 eyes of 33 patients with mean spherical equivalent of -13.12 +/- 5.31 diopters (D) (-2.5 - -24.75 D) between August 2007 and October 2010 at Dr. Lutfi Kirdar Kartal Training and Research Hospital, Second Eye Clinic. The mean age of the patients was 32.84 +/- 9.95 years (18-55 years) 24 (72.7%) were male and 9 (27.3%) were female. The study was designed as prospective case series. The patients were evaluated regarding visual acuity, refraction, endothelial cell count, and complications in postoperative period. Results: The mean follow-up time was 21.5 +/- 4.9 (12-24 months) months. The mean spherical equivalent was 1.29 +/- 1.53 D (-5.6 D - +2.60 D) at the last postoperative follow-up visit. Visual acuity was better or equal to preoperative best-corrected value in 42 (72.4%) of eyes at the last follow-up visit postoperatively. Mean spherical equivalent was regressed to -1.13 +/- 1.59D at 1-month and 1.39 +/- 1.53D at 24-month postoperative follow-up visit. Pupillary-block glaucoma in 1 eye (1.7%), anterior subcapsular opacification not affecting the vision in 4 eyes, and retinal detachment in 1 eye were detected at follow-up visits. Discussion: ICL implantation was observed to be an effective and safe method for correction of myopia in two year follow-up. As possible retinal complications may develop, the patients must be followed carefully during the preoperative and postoperative period.
