Abstract Details

Purpose:

To observe the long-term clinical efficacy of implantable collamer lens (ICL) for the correction of myopia in China.

Setting:

Chongqing Aier Eye Hospital, Chongqing, China

Methods:

A multicenter retrospective study. A total of 286 eyes from 3 sites with complete 5-year follow up were selected from 1872 eyes which underwent implantation of ICL（V4）from December 2009 to May 2014. The uncorrected distance visual acuity (UCVA), best corrected distance visual acuity (BCVA), spherical equivalent (SE), intraocular pressure, corneal endothelial count (ECD), axis length (AL), vault and anterior chamber data were analyzed for the preoperative and last postoperative visits(5.5±0.8) years (P＜0.05).

Results:

At the last visit, the mean UCVA and mean BCVA were both better than pre-operation(P＜0.001). The SE was (-0.95 ± 0.87) D (range, -2.63D to 0 D). The safety index was 1.25±0.23 and the effective index was 0.93±0.27. The mean vault was (407±198) um (range, 24 um to 1300um). No serious complications occurred.

Conclusions:

ICL implantation surgery was effective and safe in the long-term for correction of myopia.
