Purpose To investigate the effect of anterior chamber maintainer (ACM) usage during phacoemulsification on the occurrence of pseudophakic retinal detachment (PRD) in high myopia. Design A retrospective nonrandomized comparative interventional study was conducted. Participants A total of 632 high myopic eyes of 501 patients who had eventless phacoemulsification with in-the-bag intraocular lens implantation in the period between March 2013 and December 2018. Methods Patients were divided into two groups according to the use of ACM during cataract surgery: (a) ACM group, and (b) no-ACM group. Patients were followed at 6, 12, 18, 24, 30, and 36 months after surgery for detection of PRD. The time-related cumulative incidence of RD in each group was evaluated by means of Kaplan–Meier survival curves. Results In the ACM group, the 3-year cumulative incidence of RD was 2.4% compared with 5.9% in the other group (P=0.039). Regarding age, the 3-year cumulative incidence of RD increased significantly in the younger age group when the ACM was not used (P=0.023), whereas it was not when the ACM was used. Using the ACM increased the 3-year cumulative survival ratio from 86.2 to 92% in patients with a posterior staphyloma (P=0.03). Conclusion ACM is a potential prophylactic intraoperative tool against PRD in highly myopic eyes.
