AIM: To analyze of refractive status after vitrectomy combined with phacoemulsification in patients with vitreoretinal disease and cataract.

METHODS: A total of 150 patients with vitreoretinal disease and cataract were treated in our hospital from January 2014 to November 2016. According to the random number table method they were divided into two groups: combination group(75 cases)with vitrectomy combined with phacoemulsification, the control group(75 cases)with vitrectomy first, then phacoemulsification surgery. The recovery of visual acuity and the change of the axial length of the eyes were observed. The patients were followed up for 6mo, and the postoperative complications were recorded.

RESULTS: After treatment, number of patients in the two groups with visual acuity ≥0.1 were significantly improved compared with before treatment(P<0.05), and the percent in combination group was 95%, higher than 63% in the control group(P<0.05). There were no significant changes in the axial length before and after the operation in the two groups(P>0.05), and there was no significant difference between the groups before and after treatment(P>0.05). The refractive status of combination group shifted to myopia, that of control group shifted to hyperopia, two groups had no statistically significant difference on numerical prediction(P<0.05). The difference was statistically significant on the actual values(P<0.05). The complication rate in the combination group was 24%, which was lower than 40% in the control group, and the difference was statistically significant(P<0.05).

CONCLUSION: Vitrectomy combined with phacoemulsification on vitreoretinal diseases with cataract patients is effective, and safety, clinical application value is higher.
