PURPOSE: 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.
