方法：将2013-02/2014-02期间在我院眼科接受白内障超声乳化吸除术的患者120例纳入研究对象，根据视网膜病变情况分为合并视网膜病变的观察组和不合并视网膜病变的对照组，比较两组患者手术后的最佳矫正视力、视力水平、视觉诱发电位、眼压变化。

结果：手术后2wk起，观察组的患眼视力高于术前，恢复速度慢于对照组； 治疗后观察组最佳矫正视力、患眼视力水平均低于对照组； 治疗后观察组振幅12.01±4.50μV明显低于对照组，潜伏期114.29±11.32ms明显高于对照组； 术后6，12，24h眼压值23.64±4.28，24.12±5.13，18.28±3.22mmHg明显高于对照组。

结论：视网膜相关病变可导致视觉诱发电位变化、眼压升高，进而影响超声乳化白内障吸除术后视力水平的恢复。

METHODS:From February 2013 to February 2014, 120 cases with given cataract phacoemulsification were divided into observation group and control group. Cases in observation group were with of retinal associated lesions, those in control group were without retinal associated lesions. The best corrected visual acuity, ision acuity, visual evoked potential, intraocular pressure were compared between two groups.

RESULTS:Two weeks after surgery, visual acuity in observation group was higher than those of before therapy. Visual acuity recovery rate of observation group was significantly slower than that of control group; best corrected vision, visual acuity in observation group was significantly lower than that in control group; observation group's amplitude(12.01±4.50μV)was significantly lower than control group, incubation period(114.29±11.32ms)was significantly higher than control group; After 6, 12, 24h, intraocular pressure(23.64±4.28, 24.12±5.13 and 18.28±3.22mmHg)were significantly higher than control group.

CONCLUSION: Retinal associated lesions can lead to visual evoked potential change, elevated IOP, affect postoperative visual recovery level.
