Abstract:
?AlM: To evaluate the clinical effects and security of posterior chamber implantable Collamer lens ( lCL ) implantation in patients with extreme highly myopia.
?METHODS:ln this study, 18 patients ( 32 eyes ) with extreme highly myopic patients who had undergone posterior chamber lCLs implantation from July 2010 to July 2013 were evaluated. Diopter -10. 5 ~ 19. 0D, and astigmia -0. 5 ~4. 5DC. Changes in intraocular pressure ( lOP ) , refraction, visual acuity and corneal endothelium, anterior chamber depth, iris, high arch, lens were noted at 1d, 1wk, 1, 3mo and 1a after surgery respectively, and follow-up was of 1a.
? RESULTS: Before surgery, the uncorrected visual acuity (UCVA) were 0. 01~0. 05, and the best spectacle-corrected visual acuity ( BSCVA) were 0. 4 ~ 1. 0. One month after surgery, the UCVA were 0. 5~1. 2. The mean vault were 547±222 μm (95%CI 442~672μm) and 528±268μm (95%CI 354 ~635μm) for 1mo and 1a, respectively (P = 0. 81), and there was no significant difference. Anterior subcapsular opacities in 1 eye, mild and transient increase in lOP in 3 eyes, and chronic pigment dispersion in 2 eyes were observed. There was no serious complication.
?CONCLUSlON: Posterior chamber phakic intraocular lens implantation is an effective and safe method for correcting patients with extreme highly myopia.
