目的-评价穿透性角膜移植术中单次连续缝合的三种技术，即扭矩、反扭矩和无扭矩。方法-在本前瞻性研究中，53名患者的53只眼睛使用扭矩（17名患者）、反扭矩（18名患者）和无扭矩（18名患者）缝合技术进行了穿透性角膜移植术。患者在 4 周、3 个月和 6 个月时进行随访。每次随访时均测定三组的角膜曲率、视频角膜曲率、屈光散光和最佳矫正视力。如果散光>3屈光度，则在角膜移植后4周进行缝合调整。结果-扭矩组的初始散光高于其他两组，尽管没有统计学意义。缝线调整后，所有三组的散光均显着下降 (p
Aim-To evaluate the three techniques of single continuous suturing-namely, torque, antitorque, and no torque in penetrating keratoplasty.Methods-53 eyes of 53 patients underwent penetrating keratoplasty using torque (17 patients), antitorque (18 patients), and no torque (18 patients) suturing techniques in this prospective study. Patients were followed up at 4 weeks, 3 months, and 6 months. Keratometric, videokeratographic, refractive astigmatism, and best corrected visual acuity were determined in all the three groups at each follow up visit. Post-keratoplasty suture adjustment was done at 4 weeks, if the astigmatism was >3 dioptres.Results-The initial astigmatism in the torque group was higher than in the other two groups, although it was not statistically significant. Following suture adjustment, there was a significant decrease in astigmatism in all the three groups (p
