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.
我们报告了一名患者，其在放射状角膜切开术（RK）后使用可植入式Collamer晶状体（ICL，STAAR Surgical公司生产）矫正远视。明显屈光不正从术前的+5.50 -1.5×85改善至术后的+0.50 -1.25×90，术前未矫正视力（UCVA）为0.2，最佳眼镜矫正视力（BSCVA）为1.2，术后UCVA为0.8，BSCVA为1.2。在1年的随访期间未观察到严重并发症或渐进性远视移位。鉴于切开角膜的生物力学不稳定性，远视ICL植入可能是RK后矫正远视的一种替代手术选择。
