Title: Visual Improvement in High Myopic Amblyopic Adult Eyes following Phakic Anterior Chamber Intraocular Lens Implantation
Abstract: Purpose: To evaluate the efficacy and safety of angle-supported phakic anterior chamber intraocular lenses in amblyopic adult eyes with very high myopia.Methods: We evaluated 12 eyes in nine patients with very high myopic amblyopia who received angle-supported phakic intraocular lenses (Phakic 6H Ⓡ ) and followed them for more than six months.Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and complications were evaluated.A satisfaction score was rated by patients using a 5-point (1~5) numeric scale.Results: The mean age of patients was 37.3±9.4years, ranging from 29 to 59 years old.The preoperative mean refraction (spherical equivalent, SE) was -20.10±5.41diopters (D).The postoperative mean refraction (SE) was -1.75±0.76D at six months.The postoperative BCVA improved an average 3.92±1.24lines over preoperative values, and mean endothelial cell loss was 8.9% at six months.Development of cataracts, glaucoma, and pupil abnormalities were not demonstrated in any case during the study.The patients were all very satisfied, as the average satisfaction score was 4.3.Conclusions: This study indicates that angle-supported phakic anterior chamber intraocular lens implantation may be an effective surgical alternative for the correction of amblyopic adult eyes with very high myopia.However, long-term evaluation is necessary to assess possible complications and long-term safety.
