摘要:
      目的:角膜屈光手术中静态眼球旋转(static cyclotorsion component, SCC)和动态眼球旋转(dynamic cyclotorsion component, DCC)的方向和程度变化分析。

 

     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。

Abstract:
      AIM: To analyze the direction and degree of static cyclotorsion component(SCC)and dynamic cyclotorsion component(DCC)in corneal refractive surgery.

 

     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.
