年龄相关性白内障超声乳化手术后眼轴的变化分析

Changes of Eye Axis after Phacoemulsification for Age-Related Cataract

摘要: 目的：观察年龄相关性白内障患者行超声乳化吸除联合人工晶体植入术后眼轴的变化。方法：选择眼轴长度在22~26 mm的年龄相关性白内障患者71例(96眼)，行白内障超声乳化吸除联合人工晶体植入术，术后随访3月，分别记录手术前及手术后1日、7日、1月、3月的眼轴长度，分析其眼轴变化情况。结果：术后1天、7天、1月、3月的眼轴长度均较术前缩短，具有统计学差异(P < 0.05)。术后1月与术后3月比较，差异无统计学意义(P > 0.05)，手术后1月眼轴变化趋于稳定。结论：年龄相关性白内障超声乳化术后眼轴变短，在术前预留人工晶体度数时要考虑到术后眼轴变化引起的度数改变，以使术后目标屈光度更加准确；眼轴长度在手术后1月趋于稳定，此时可以进行验光配镜。

Abstract: Objective: To observe the changes of eye axis in age-related cataract patients after phacoemulsifi-cation combined with intraocular lens implantation. Methods: A total of 71 cases (96 eyes) of age-related cataract patients with the axial length of 22 - 26 mm were selected for cataract phacoemulsification combined with intraocular lens implantation, followed up for 3 months after surgery, and the axial length before and after surgery of 1 day, 7 days, 1 month and 3 months were recorded, respectively, to analyze the changes of the axial length. Results: The axial length at 1 day, 7 days, 1 month and 3 months after surgery was shorter than that that before surgery, with statis-tical difference (P < 0.05). There was no statistically significant difference between 1 month after surgery and 3 months after surgery (P > 0.05), and the axial changes tended to be stable 1 month after surgery. Conclusion: After phacoemulsification of age-related cataract, the eye axis becomes shorter, and the degree change caused by the change of eye axis should be taken into account when the intraocular lens degree is reserved preoperatively, so as to make the postoperative target diopter more accurate. The axial length of the eye tends to be stable 1 month after surgery, at which time optometry and optometry can be performed.
