Results of Nuvita Phakic Anterior Chamber Intraocular Lens for High Myopia

ABSTRACT

PURPOSE: The study was designed to evaluate the clinical results of an anterior chamber intraocular lens implantation (Nuvita MA 20 implantation) on high myopic patients. METHODS: We reviewed the clinical results of Nuvita MA 20 implantation surgery in 6 high myopic patients (11 eyes) with more than -7.0 diopters (D) for a year after the surgery. One patient was male,five patients were female and the mean age was 31.5 years old (25~41 years old). RESULTS: Mean preoperative spherical equivalent was -16.61 4.9 D and mean postoperative spherical equivalent was -0.9+/-0.5 D at 1 week, -1.275+/-1.14 D at 1 month, -1.14+/-1.22 D at 3 months, -1.18+/-1.18 D at 6 months and -1.05+/-1.2 D at 12 months. Mean uncorrected visual acuity preoperatively was 0.03+/-0.06 and postoperatively was 0.6+/-0.25 at 1 week, 0.57+/-0.25 at 1 month, 0.67+/-0.4 at 6 months, 0.8+/-0.32 at 12 months. Postoperative complications included 6 eyes of IOL rotation (55%), 4 eyes of pupil distortion (36%), 1 eye of intraocular pressure elevation (9%), 1 eye of pupillary block (9%), 1 eye of IOL decentration (9%) and 1 eye of nuclear cataract (9%), but serious postoperative complications such as retinal detachment and bullous keratopathy were not found. Mean endothelial cell density was 2677+/-148 (cells/mm2) at preoperative period, 2576+/-167 (cells/mm2) at 1 month, 2546+/-127 (cells/mm2) at 3 months, 2490+/-171 (cells/mm2) at 6 months and 2408+/-133 (cells/mm2) at 12 months. CONCLUSIONS: The implantation of Nuvita MA 20 into anterior chamber is considered to be a safe method of treatment for patients with high myopia.
