摘要
目的:探讨高度近视合并白内障患者白内障术后有效晶状体位置的变化。方法:收集白内障超声乳化摘除联合人工晶状体植入术的高度近视合并白内障患者21例共27眼,记录术后1 d、1周、1个月视力、屈光度、有效晶状体位置。结果:高度近视合并白内障患者术后1 d,1周,1个月有效晶状体位置分别为(4.17±0.39),(4.09±0.38),(4.31±0.44) mm,且组间比较差异有统计学意义(P<0.05)。有效晶状体位置的实际轴向运动为(0.19±0.13) mm,与晶状体厚度呈正相关(r=0.648,P<0.001),与术前眼轴无相关关系(r=0.227,P=0.255)。结论:高度近视合并白内障患者术后1 d至1周人工晶状体轻度前移而造成近视偏移,而术后1个月时则呈远视偏移,且术后有效晶状体位置位移与术前晶状体厚度相关。
Objective: To investigate the change and influencing factors of the effective lens position after cataract surgery in high myopia eyes. Methods: We collected 27 eyes of 21 patients with high myopia who underwent phacoemulsification and intraocular lens implantation. The visual acuity, diopter and effective lens position were recorded 1 day, 1 week, and 1 month after operation. Results: The effective lens position of high myopia combined with cataract patients at 1 day, 1 week, and 1 month was (4.17±0.39),(4.09±0.38), and (4.31±0.44) mm, respectively. The effective lens positions significantly differed between the groups after surgery (P<0.05). The ELPRMS was (0.19±0.13) mm. The ELPRMS was positively correlated with the lens thickness (r=0.648, P<0.001), whereas was not correlated with the preoperative axial length (r=0.227, P=0.255). Conclusion: High myopic patients with cataract have a slight forward movement of the effective lens position from 1 day to 1 week after surgery, and a hyperopic shift from 1 week to 1 month. The displacement of effective lens position after surgery is correlated with the preoperative lens thickness.
