Surgical experience with angle-supported phakic IOLs for high myopia correction

Abstract

ABSTRACT Purpose. To study the clinical results of angle-supported phakic intraocular lenses (pIOL) implantations in patients with high myopia. Material and methods. The study group included 16 patients (32 eyes) aged 25±5 years (from 21 to 36 years) with high myopia – 13.33±2.82D (from -8.25 to -18.25D), where excimer laser refractive procedures were not indicated due to the thin cornea pachymetry readings and/or high predicted residual refractive error. The conventional examinations were performed preoperatively and in different postoperative periods (follow-up: up to 1 year). The preoperative best corrected visual acuity (BCVA) was 0.68±0.18 (within the range from 0.3 to 1.0). In addition to the standard examinations, special diagnostic techniques were carried out including: keratotopography pupillometry, anterior segment OCT, endothelial microscopy using the confocal m icroscope. Results. All surgeries were uneventful. On the first postoperative day, the uncorrected visual acuity (UCVA) from 0.90 to 1.00 was noted in 88% of cases, the UCVA higher than 0.6 – in 94%. The average spherical error postoperatively was -0.54±0.56D (range from 0.00 to -1.25D) and remained stable throughout the entire follow-up. The endothelial cell loss 1 year after the surgery was equal to 3.25%. All patients were satisfied with the results of treatment. Conclusion. Implantation of anterior chamber angle-supported pIOL Acrysof Cachet in patients with a high myopia considered to be safe, effective, and providing rapid visual rehabilitation.
