摘　　要：目的探讨超高度近视行PRK的手术方法。方法将一期手术较重的创伤愈合反应分割为两期较轻的创伤愈合反应,据此指导思想设立分期PRK方案用于治疗超高度近视,并与常规PRK方案对照组进行疗效安全性对比分析。结果-12D以上超高度近视132例184眼分为两组:常规PRK组113眼,术后半年、1年、2年随访时残留屈光度在±1D范围内眼数分别占50.0％、33.3％、20.0％,术后Ⅱ级以上角膜上皮下混浊发生率分别占8.7％、2.6％、3.3％;分期PRK组71眼,术后半年、1年、2年随访时残留屈光度在±1D范围内眼数分别占77.4％、70.8％、68.8％,术后Ⅱ级以上角膜上皮下混浊发生率分别占1.6％、0、0。结论分期PRK手术方案治疗超高度近视较常规方案更安全、有效,可作为治疗超高度近视的良好选择。Objective To investigate procedures of photorefractive keratectomy (RPK) in correction of extremely high myopia. Methods Two-stage PRK was performed in correction of extremely high myopia. Its effect was compared with that of the conventional 1 -stage PRK. Results One hundred and thirty two cases (184 eyes) of extremely high myopia above ±12D were divided into 2 groups: the conventional PRK group including 113 eyes and 2-stage PRK group including 71 eyes. In the conventional group, at half a year, 1 year and 2 year after operation, the surplus diopter was within ±1D in 50.0%, 33.3% and 20.0% eyes respectively and the rate of corneal haze greater than grade Ⅱ was 8.7%, 2.6% and 3.3% respectively. In the 2-stage group, at the corresponding points of time, the surplus diopter was within ±1D in 77.4%, 70.8% and 68.8% eyes respectively and the rate of corneal haze greater than grade Ⅱ was 1.6%, 0 and 0 respectively. Conclusion Compared with the conventional PRK, PRK by stages is more effective and safe for extremely high myopia.
