Abstract Details

Purpose:

To investigate the safety and efficacy of implanting a posterior chamber implantable collamer lens with a central hole (ICL V4c) in cases of high myopia with peripheral primary iris or ciliary body cysts.

Setting:

Prospective study.

Methods:

37 eyes of 19 patients with peripheral primary iris or ciliary body cysts detected by ultrasonic biological microscope (UBM) were included, with spherical powers of -10.26�Â�±3.28D and cylinder powers of -1.71�Â�±1.18D. Each patient received UBM and a routine examination before implantation of the ICL V4c. A routine postoperative follow-up was performed to observe changes in the primary iris or ciliary body cyst ranged from 3 to 18 months.

Results:

At the last follow-up, 56.8% of patients achieved the same corrected distance visual acuity as their preoperative measurements. The efficacy index and safety index were 0.95 and 1.11, respectively. 66.7% of the spherical equivalents were between �Â�±0.5D. The postoperative mean spherical equivalents at 1, 3, 6, 12 and 18 months were -0.45�Â�±0.31D, -0.39�Â�±0.29 D, -0.36�Â�±0.30D, -0.39�Â�±0.38D and -0.48�Â�±0.23D (P=0.789); The vaults were 516�Â�±140�Î�¼m, 548�Â�±124�Î�¼m, 498�Â�±133�Î�¼m, 582�Â�±161�Î�¼m and 557�Â�±110�Î�¼m (P=0.355). There were no changes in size, number or position of the iris, ciliary body cysts.

Conclusions:

ICL V4c implantation is safe and effective for highly myopic patients with peripheral primary iris and ciliary body cysts. The cysts did not change after operation.
