Clinical effects of implantable collamer lens implantation to correct high myopia

Abstract:

AIM:To observe the clinical effect and safety of implantable collamer lens(ICL/TICL)for correctiong high myopia.

METHODS:The 160 cases with 310 eyes accepted ICL/TICL from October 2010 to June 2014 in our hospital were involved in the study. The uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), refractive state, intraocular pressure(IOP), corneal endothelial counting and complications were analyzed.

RESULTS:The visual acuity and refractive error were significantly improved and the improvement remained stable. The postoperative UCVA was >0.8 in 86% eyes. No decline of BCVA was observed with 11% increased by 1 line and 68% increased ≥2 lines. The actual refractive state of 96% eyes was ±1.00D around the expected degree. The IOP in 14 eyes increased, but was below 28mmHg at 1h after surgeries. One eye was performed intraocular lens implantation and lens extraction after the lens injury. There were 1 eye with rotation, 3 retinal detachments, and 1 macular hemorrhage after surgeries.

CONCLUSION: ICL/TICL implantation to correct high myopia is effective and safe with high satisfaction, and is worthy of promotion. Its long-term complications need further observation.
