CLEAR LENS EXTRACTION VERSUS PHAKIC IOL IMPLANTATION: A PROSPECTIVE STUDY OF TWO PROCEDURES IN PATIENTS WITH HIGH MYOPIA

Abstract

Purpose: To compare clear lens extraction (CLE) and phakic intraocular lens posterior chamber intraocular (PIOL) lens implantation (Artisanintraocular lens (IOL) & Implantable Collamer Lens (ICL) for correction of high myopic patients younger than 40 years. Methods: A prospective nonrandomized study included 64 eyes (45 highly myopic patients) divided into three groups: Group A; received CLE and IOL implantation, Group B; received Artisan PIOL, and Group C; received ICL PIOL. All cases were evaluated on the 1 day, 1 week, 1 month, 6 month, 12 month, and 18 month postoperatively. The evaluation included assessment of visual acuity, IOP, refraction, IOL stability & search for postoperative complications. Results: The postoperative efficacy index after 1 month was (101.7%, 98.6% & 98.8%) and after 18 months (100.3%, 98.6% & 98.15%) for groups A, B & C respectively. While the postoperative spherical equivalent refraction at 18 months was variable. Group A included 17 eyes within 1.0 D and 9 eyes within 0.5 D. While group B included 18 eyes within 1.0 D and 11 eyes within 0.5 D, and group C included 22 eyes within 1.0 D and 11 eyes within 0.5 D. Conclusions: There was no difference between clear lens extraction and phakic IOL implantation as a management of high myopia.
