This study compared the postoperative axial rotation of the toric intraocular lens (T-IOL) after cataract surgery combined with vitrectomy versus cataract surgery alone.
This retrospective, non-randomized, observational study enrolled patients who underwent cataract surgery combined with vitrectomy in one eye and cataract surgery alone in the contralateral eye. AcrySof Toric IOLs (Alcon Laboratories) were implanted in both eyes of the same patient. The axial rotation of the T-IOL was analyzed 3 months postoperatively using photographs obtained during and after surgery. In the combined group, T-IOL axial alignment was performed before vitrectomy. Preoperative corneal astigmatism and postoperative residual astigmatism were also compared in both groups.
This study examined 36 eyes of 18 patients (74.7 ± 6.8 years). The axial rotation was 2.94 ± 1.70° in the cataract group versus 3.06 ± 2.34° in the combined group 3 months postoperatively, and the difference lacked significance (p = 0.98). In the combined group, the mean axial rotation during surgery was 2.17 ± 1.80°. Axial rotation within 5° was observed in 17 of 18 eyes (94.4%) in the cataract group and 16 of 18 eyes (88.9%) in the combined group, with no significant difference (p = 0.54). The comparison of postoperative residual astigmatism with preoperative corneal astigmatism revealed a significant improvement from 1.49 ± 0.40 D to 0.39 ± 0.47 D in the cataract group (p < 0.0001) and from 1.61 ± 0.40 D to 0.42 ± 0.43 D in the combined group (p < 0.0001).
The postoperative axial rotation of the T-IOL in eyes that underwent cataract surgery combined with vitrectomy was stable and comparable to that of eyes that underwent cataract surgery alone.
本研究比较了白内障手术联合玻璃体切除术后与单纯白内障手术后散光型人工晶状体（T-IOL）的术后轴向旋转情况。
本回顾性、非随机、观察性研究纳入了一只眼睛接受白内障手术联合玻璃体切除术，对侧眼睛接受单纯白内障手术的患者。同一名患者的双眼均植入了爱尔康公司的AcrySof Toric IOL。术后3个月，使用手术期间及术后获得的照片分析T-IOL的轴向旋转情况。在联合手术组中，在玻璃体切除术之前进行T-IOL轴向对齐。同时比较两组术前角膜散光和术后残余散光情况。
本研究检查了18例患者的36只眼睛（年龄74.7±6.8岁）。术后3个月，白内障组的轴向旋转度数为2.94±1.70°，联合手术组为3.06±2.34°，差异无统计学意义（p = 0.98）。在联合手术组中，手术期间的平均轴向旋转度数为2.17±1.80°。白内障组18只眼中有17只（94.4%）、联合手术组18只眼中有16只（88.9%）的轴向旋转度数在5°以内，差异无统计学意义（p = 0.54）。术后残余散光与术前角膜散光的比较显示，白内障组从1.49±0.40 D显著改善至0.39±0.47 D（p < 0.0001），联合手术组从1.61±0.40 D显著改善至0.42±0.43 D（p < 0.0001）。
接受白内障手术联合玻璃体切除术的眼睛中T-IOL的术后轴向旋转情况稳定，与单纯接受白内障手术的眼睛相当。
