| Popis: | Purpose To evaluate longitudinal changes in Implantable Collamer Lens phakic intraocular lens (pIOL) position after implantation. Setting Department of Ophthalmology, Zhejiang University, Hangzhou, China. Design Retrospective case series. Methods Myopic eyes that had pIOL implantation with a follow-up of at least 24 months were evaluated. Ultrasound biomicroscopy examinations were performed at each visit. Results The study enrolled 62 eyes (31 patients; 22 women, 9 men) ranging in age from 21 to 46 years. The manifest spherical equivalent ranged from −8.25 to −18.75 diopters. A significant increase (mean 36 μm ± 50 [SD]) in the endothelium–anterior pIOL distance occurred between 1 month and 3 months ( P =.000); afterward, the distance decreased slowly ( P >.05). The largest decrease (mean 47 ± 17 μm) in central vault occurred between 1 month and 3 months ( P =.009). The largest decrease (mean 21 ± 14 μm) in peripheral vault occurred between 1 month and 3 months ( P =.000). Conclusions A significant increase in the endothelium–anterior pIOL distance occurred from 1 month to 3 months postoperatively, after which a slight decrease occurred over time. Central vault and peripheral vault had a tendency to decrease over time. Financial Disclosure No author has a financial or proprietary interest in any material or method mentioned. |
