title: Implantable Collamer lens for hyperopia after radial keratotomy.
abstract: We report a patient in whom an implantable Collamer lens (ICL) (Staar Surgical) was used to correct hyperopia after radial keratotomy (RK). The manifest refraction improved from +5.50 -1.5 x 85 preoperatively, with an uncorrected visual acuity (UCVA) of 0.2 and a best spectacle-corrected visual acuity (BSCVA) of 1.2, to +0.50 -1.25 x 90 postoperatively, with a UCVA of 0.8 and a BSCVA of 1.2. No serious complications or progressive hyperopic shift was observed during the 1-year follow-up. In light of the biomechanical instability of the incised cornea, hyperopic ICL implantation may be an alternative surgical option for the correction of hyperopia after RK.
