AIM: To explore the effects of double-incision phacoemulsification combined with trabeculectomy on visual acuity, intraocular pressure and complications in patients with glaucoma complicated with cataract.

METHODS: The clinical data of each 68 patients(68 eyes)with glaucoma and cataract who were given double-incision(observation group)and single-incision(control group)phacoemulsification combined with trabeculectomy from April 2016 to October 2017 were retrospectively analyzed. The visual acuity and corneal endothelial cell status(density, area)before operation and at 1mo after operation, and occurrence of complications(hyphema, corneal endothelial edema, anterior chamber fibrinous exudation, filtering bleb scarring)within 1mo after operation were recorded in the two groups. And the differences of intraocular pressure and astigmatism degree were compared between the two groups before operation and at 1 and 6mo after operation.

RESULTS:At 1mo after operation, the visual acuity in the two groups was better than that before operation(P<0.05). However, there was no significant difference between the two groups(P>0.05). At 1mo after operation, the area of corneal endothelial cell in the two groups was larger than that before operation(P<0.05)while the density of corneal endothelial cell was lower than that before operation(P<0.05), and the changes in control group were greater than those in observation group(P<0.05). The total incidence rate of postoperative complications in observation group was significantly lower than that in control group(P<0.05). The intraocular pressure in the two groups after operation was lower than that before operation(P<0.05), but there was no significant difference between at 1mo after operation and at 6mo after operation(P>0.05). And there was no statistically significant difference between the two groups(P>0.05). The postoperative astigmatism degree in the two groups was higher than that before operation(P<0.05), and the index at 1mo after operation was higher than that at 6mo after operation(P<0.05), and the index in control group was higher than that in observation group(P<0.05).

CONCLUSION:Double-incision phacoemulsification combined with trabeculectomy has significant effects on patients with glaucoma and cataract. Although double-incision surgery and single-incision surgery have similar effects in improving visual acuity and intraocular pressure, double-incision surgery has less damage to the operative area, and it can reduce the postoperative corneal endothelial injury and the postoperative astigmatism degree, and it can also reduce the postoperative complications, and has a positive significance in promoting the disease outcomes.
