PURPOSE
To report on a patient in whom hyperopic Implantable Collamer Lenses (ICL, STAAR Surgical, Nidau, Switzerland) and limbal relaxing incisions have been beneficial for the correction of hyperopic astigmatism after laser in situ keratomileusis (LASIK).
METHODS
The 48-year-old man had undergone LASIK to correct high myopia 5 years earlier. Preoperatively, the manifest refraction was +2.25, -1.00 x 160, with an uncorrected visual acuity of 0.15 and a best spectacle-corrected visual acuity of 1.5.
RESULTS
Postoperatively, the manifest refraction was +0.50, -0.5 x 165, with an uncorrected visual acuity of 1.0 and a best spectacle-corrected visual acuity of 1.2. No serious complications were observed during the 10-month observation period.
CONCLUSION
Hyperopic Implantable Collamer Lenses implantation combined with limbal relaxing incisions may be an alternative for the treatment of hyperopic astigmatism after overcorrected myopic LASIK.
目的
报告 1 例近视激光原位角膜磨镶术（LASIK）术后过矫性远视散光患者，应用有晶状体眼后房型人工晶状体（ICL，STAAR Surgical，瑞士尼达）联合角膜缘松解切口手术的治疗效果。
方法
患者男，48 岁，5 年前行 LASIK 矫正高度近视，术前最佳矫正视力为 1.5。本次术前检查发现，患者右眼远视力为 0.15，右眼等效球镜为+2.25D，柱镜为-1.00D，轴位 160°；左眼等效球镜为+0.50D，柱镜为-0.50D，轴位 165°。
结果
术后 10 个月，右眼等效球镜为+0.50D，柱镜为-0.50D，轴位 165°，最佳矫正视力为 1.0；左眼等效球镜为+0.50D，柱镜为-0.50D，轴位 165°，最佳矫正视力为 1.2，未观察到严重并发症。
结论
对于 LASIK 术后过矫性远视散光，ICL 植入联合角膜缘松解切口手术可能是一种替代治疗方法。
