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 (P0. 05); DCC in T-PRK group (2. 86o±1. 14o) was higher than that of FS-LASIK group ( 2. 17o ± 1. 09o), and the difference was statistically significant (P0. 05). The SCC of subjects in operation was positively correlated with UCVA, BCVA, spherical equivalent refraction and high order aberrations ( PCONCLUSION:
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.
