【摘要】：目的探讨有晶体眼后房型近视合并散光人工晶体(toric implantable collamer lens,TICL)植入矫治中、高度近视伴散光术后人工晶体发生旋转的情况及相关因素。方法对我科就诊的71例中、高度近视合并散光患者共125眼植入后房型人工晶体。术后随访1年以上,观察术后3、6、12个月人工晶体眼内发生旋转的方向及角度,并与术前散光度、术中人工晶体植入方向、角度及术后拱高做相关性分析。结果术后3个月TICL发生顺时针及逆时针方向旋转的比例无统计学差异(P0.05)。术后3、6、12个月之间相互比较TICL旋转角度无统计学差异(P0.05)。行Pearson相关性分析,术后TICL旋转角度与术前散光度数有相关性(P0.01),与术中TICL安置旋转角度有相关性(P0.05),与术后拱高无相关性(P0.05)。结论 TICL植入术后发生旋转与术前散光度数、术中晶体植入角度均有一定相关性,对于高度散光患者,人工晶体植入时将旋转角度控制在10°内能有效减少术后旋转,增加稳定性。
[Abstract]:Objective to investigate the rotation of intraocular lens (IOL) with posterior chamber myopia and astigmatism intraocular lens (toric implantable collamer lens,TICL) implantation in patients with high myopia and astigmatism. Methods 125 eyes of 71 patients with high myopia and astigmatism were implanted with posterior chamber intraocular lens. All patients were followed up for more than 1 year. The rotation direction and angle of intraocular lens were observed 3 and 12 months after operation, and correlation analysis was made with preoperative astigmatism, intraocular lens implantation direction, angle and postoperative arch height. Results there was no significant difference in the proportion of clockwise and counterclockwise rotation in TICL 3 months after operation (P0.05). There was no significant difference in TICL rotation angle between 6 months and 12 months after operation (P0.05). Pearson correlation analysis showed that postoperative TICL rotation angle was correlated with preoperative astigmatism (P0.01), with intraoperative TICL placement rotation angle (P0.05), and had no correlation with postoperative arch height (P0.05). Conclusion rotation after TICL implantation is related to the degree of astigmatism before operation and the angle of intraoperative lens implantation. For patients with high astigmatism, controlling rotation angle within 10 掳during implantation of intraocular lens can effectively reduce postoperative rotation and increase stability.
