方法：回顾性分析在本院行角膜屈光手术的患者130例260眼，根据手术方式分为飞秒准分子激光原位角膜磨镶(femtosecond laser-assisted laser in situ keratomileusis， FS-LASIK)组和准分子激光角膜切削术(T-photorefractive keratectomy，T-PRK)组，比较两组患者术后各参数的差异； 比较两组患者术中的SCC成功率、SCC、DCC、眼球旋转方向的差异； 以及SCC、DCC与患者术后的各参数的相关性分析。

结果：T-PRK组术后的高阶像差和球差高于FS-LASIK组，且差异具有统计学意义(P<0.05)； T-PRK组术中SCC成功98眼，成功率为81.7%，FS-LASIK组术后SCC成功82眼，成功率为58.6%，两组患者术中的SCC成功率的差异具有统计学意义(P<0.05)； T-PRK组术中SCC为(3.52°±2.17°)，与FS-LASIK组(3.49°±2.26°)的差异无统计学意义(P>0.05)； T-PRK组术中DCC为(2.86°±1.14°)，高于FS-LASIK组(2.17°±1.09°)，且差异具有统计学意义(P<0.05)； 两组患者术中眼球旋转方向的分布无统计学差异(P>0.05)。研究对象术中SCC与裸眼视力、最佳矫正视力、等效球镜屈光度、高阶像差呈正相关(P<0.05)； 研究对象术中DCC与裸眼视力、高阶像差呈正相关(P<0.05)。

结论：T-PRK手术中SCC成功率高于LASIK手术，T-PRK手术中的DCC高于LASIK手术，准确的测量静态及动态眼球旋转可有效的对其进行补偿。

METHODS:Retrospective analysis. Totally 130 patients(260 eyes)with corneal refractive surgery in our hospital, according to the operation method were divided into femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)group and T-photorefractive keratectomy(T-PRK)group, the differences of the parameters of the two groups were compared; the differences of SCC success rate, SCC, DCC, and the eyeball rotation direction were compared between the two groups; correlation analysis on SCC, DCC and the parameters of postoperative patients were performed.

RESULTS:High order aberrations and spherical aberration in the T-PRK group after operation was higher than those of FS-LASIK group, and the difference was statistically significant(P<0.05); in T-PRK group SCC in the operation was successful in 98 eyes, the success rate was 81.7%; in FS-LASIK group SCC in the operation was successful in 82 eyes, the success rate is 58.6%, the difference of SCC success rate between the two groups was statistically significant(P<0.05); SCC in T-PRK group was 3.52°±2.17° and FS-LASIK group was 3.49°±2.26°, there was no significant difference(P>0.05); DCC in T-PRK group(2.86°±1.14°)was higher than that of FS-LASIK group(2.17°±1.09°), and the difference was statistically significant(P<0.05). There was no statistical difference in the direction of rotation of the eyeball in operation between the two groups(P>0.05). The SCC of subjects in operation was positively correlated with UCVA, BCVA, spherical equivalent refraction and high order aberrations(P<0.05); the DCC of subjects in operation was positively correlated with UCVA and high order aberrations(P<0.05).

CONCLUSION:The success rate of SCC in T-PRK surgery is higher than that in LASIK, DCC in T-PRK surgery is higher than that in LASIK, and accurate measurement of SCC and DCC can be effective to compensate for it.
