AIM: To study the relationship of retinal associated lesions and postoperative visual acuity of cataract phacoemulsification.

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.
