Early experience with implantable collamer lens in the management of hyperopia after radial keratotomy.
OBJECTIVE
To report the initial experience of the use of implantable collamer lens (ICL) in the management of hyperopia after radial keratotomy (RK).


METHODS
Single-center, retrospective chart review. Four eyes of 3 patients with secondary hyperopic shift after myopic RK had a mean spherical equivalent of 5.31 D (range, 3.25-9 D) on presentation. All of them underwent ICL implantation to correct the refractive error.


RESULTS
There were no intraoperative complications. At a mean follow-up of 5.5 months (range, 3-7 months), the mean uncorrected visual acuity improved from 20/130 preoperatively to 20/24 postoperatively, and the mean spherical equivalent decreased from 5.31 D preoperatively to 0.08 D postoperatively. At 1-month follow-up, all eyes had an uncorrected visual acuity better than or equal to preoperative best spectacle-corrected visual acuity. Two eyes were within 0.25 D and all were within 0.5 D of the predicted refractive target.


CONCLUSIONS
ICL implantation is an effective surgical option to consider in the management of hyperopia after RK. However, a large cohort and longer follow-up are needed to determine the long-term efficacy and safety of this procedure in this clinical setting.
