目的：分析高度近视白内障患者超声乳化联合IOL植入术后视力预后的影响因素，初步探讨椭圆体带完整性与术后视力的相关性。

方法：回顾性病例研究。将临床确诊为高度近视合并白内障患者96例106眼纳入研究。术前检查后所有患者均行白内障超声乳化联合IOL植入术，对比分析术前及术后1wk，1、3、6mo患眼BCVA变化，比较不同BCVA分段手术前后患眼椭圆体带的完整性，同时分析影响患者术后视力的相关影响因素。

结果：术前和术后1wk，1、3、6mo患眼BCVA分别为0.80(0.50， 1.70)、0.51(0.28， 1.30)、0.50(0.09， 0.60)、0.30(0.22， 0.90)、0.30(0.22， 0.70)，有差异(P<0.001)； 术前和术后6mo不同BCVA分段患眼椭圆体带完整性，均有差异(P<0.001)。多元逐步回归分析显示，术后6mo时BCVA与术前BCVA和椭圆体带完整性具有相关性(P<0.05)； 和性别、年龄、术前平均角膜曲率、眼轴无相关性(P>0.05)。

结论：高度近视白内障患者经超声乳化吸除联合IOL植入术后视力改善，术后视力与椭圆体带完整性和术前视力具有相关性。

METHODS: Retrospective case review. A total of 96(106 eyes)cataract with high myopia patients were enrolled into this study. All patients received phacoemulsification and IOL implantation after preoperative examination. After 6mo of follow-up, the changes of BCVA were compared between preoperative and postoperative 1wk, 1mo, 3mo and 6mo. Compared the integrity of ellipsoidal zone with different ranges of BCVA before and after 6mo surgery. At the same time, the relevant influencing factors affecting postoperative BCVA were analyzed.

RESULTS: The median BCVA of preoperative and postoperative 1wk, 1mo, 3mo and 6mo eyes were 0.80(0.50, 1.70), 0.51(0.28, 1.30), 0.50(0.09, 0.60), 0.30(0.22, 0.90)and 0.30(0.22, 0.70), respectively, there were significant differences(P<0.001). The results showed that there were significant differences in the integrity of ellipsoidal zone with different ranges of BCVA before and after 6mo surgery(P<0.001). Multiple linear regression analysis showed that BCVA at postoperative 6mo was associated with preoperative BCVA and integrity of ellipsoidal zone(P<0.05). However, there was no correlation with age, gender, preoperative average corneal curvature and axial length(P>0.05).

CONCLUSION: The visual acuity improved after phacoemulsification combined with IOL implantation for cataract with high myopia. Postoperative visual acuity was correlated with the integrity of ellipsoidal zone and preoperative visual acuity.
