Abstract
Purpose :
To assess the safety and efficacy of collamer lens (ICL) in the posterior chamber for correction of myopia and astigmatism in patients with keratoconus
Methods :
A retrospective chart review was conducted of 27 patients diagnosed as keratoconus underwent ICL (Model V4) insertion, performed by different surgeons .All ICL surgeries and preoperative evaluations were performed at tertiary hospital
Results :
There was a statistically significant increase in mean UCVA from 20/200(range: 20/80 - count fingure) preoperatively to 20/30 (range: 20/20 – 20/100) at the last postoperative visit (P < 0.0001). There was statistically significant decrease in mean MRSE (Manifest refractive spherical equivalent) from - 8.36 ± 3.67 D (range, -2 to - 16 D) preoperatively to -0.56 ± 1.00 D (range, -2 to 1 D) postoperatively (P < 0.0001). Mean improvement in postoperative BCVA was 1 line compared to preoperatively. At the last postoperative visit, 28.6% of eyes had a BCVA of 20/20 or better compared with only 17.85% preoperatively. No intraoperative or postoperative complications occurred
Conclusions :
Our study yielded favorable results compared to other studies in the literature. However, a larger number of patients and a longer follow-up period are needed to truly assess the efficacy of ICL in the management of keratoconus with high myopia and moderate-to-high myopic astigmatism
