AIM: To investigate the influence of high perfusion irrigation during phacoemulsification on the postoperative visual function of patients with acute angle-closure glaucoma(AACG).

METHODS: Totally 35 patients(37 eyes)with AACG with cataract were included to do the surgery of phacoemulsification with goniosynechialysis. They have been followed up for 6mo. The preoperative and postoperative(3mo and 6mo)best corrected visual acuity(BCVA), intraocular pressure, mean sensitivity(MS), mean defect(MD), and square root loss variance(sLV)were measured and compared.

RESULTS: Compared with preoperative results, 3mo and 6mo BCVA were significantly improved and intraocular pressure was significantly reduced after operation, with statistically significant differences(P<0.001). There was no statistically significant difference between groups after operation(P>0.05). After surgery, 3mo and 6mo MS increased significantly, MD and sLV decreased significantly, and the difference was statistically significant(P<0.001). There was no statistically significant difference between the groups after surgery(P>0.05).

CONCLUSION: The high perfusion irrigation during phacoemulsification does not damage the visual function of patients with AACG.
