Abstract: Objective To analyze the effect of coaxial microincision (1.8 mm) phacoemulsification combined with trabeculectomy in patients with primary angle-closure glaucoma (PACG) and cataracts. Methods The medical records of 80 patients with PACG and cataract admitted to our hospital from April 2020 to April 2021 were retrospectively analyzed, and they were divided into two groups by different treatment measures. Among them, 40 patients who underwent phacoemulsification simple trabeculectomy were included in the control group, and 40 patients who underwent coaxial microincision (1.8 mm) phacoemulsification combined with trabeculectomy were included in the observation group until 3 months after surgery. The two groups were compared with intraocular pressure, central anterior chamber depth, visual acuity improvement, quality of life, and complications. Results Before surgery, there were no significant differences between intraocular pressure, central anterior chamber depth, BCVA and the scores of each dimension in GQOLI-74 (P>0.05); after surgery, the observation group's depth of central anterior chamber, BCVA and the scores of each dimension in GQOLI-74 were higher than control group's (P<0.05); but the comparison of two groups in intraocular pressure was no significant difference(P>0.05); the observation group's complication rate was lower than control group's (P<0.05). Conclusion Coaxial microincision phacoemulsification + trabeculectomy has obvious effect in the treatment of patients with PACG combined with cataracts, which can significantly control eye pressure, regulate vision, improve quality of life, and have fewer complications, high clinical application value, and worthy of vigorous application.
