%X Purpose: To determine and compare the prevalence of rhegmatogenous retinal detachment (RRD) in myopic eyes operated of posterior chamber phakic implantable collamer lens (ICL) with a control group of nonoperated myopic eyes over 10 years of follow-up.Setting: Clinica Baviera, Madrid, Spain.Design: Retrospective cohort study.Methods: There were 2 study cohorts: one with patients operated with ICL and a control group of nonoperated patients. The primary outcome of RRD was measured retrospectively, first through chart review of ICL-operated patients with at least 10 years of follow-up, then secondarily through telephone questionnaires and specialist verification for those with incomplete follow-up. Prevalence and incidence were calculated and compared, as well as their possible association with other risk factors.Results: 58 operated patients completed follow-up in our clinic. A survey of 3849 more patients was conducted for a total of 252 operated with a mean spherical equivalent (SEQ) of −12.6 diopters (D) and 221 nonoperated with a mean SEQ of −10.5 D. 7 eyes developed an RRD in the operated vs 5 eyes among the nonoperated (prevalence 1.71% vs 1.25%, respectively, P = .773). The equivalence tests, the two one-sided test and the null hypothesis test between groups, were within the 0.02 limits, confirming the null hypothesis, and compared survival curves did not show significant differences (P = .59).Conclusions: ICL implantation surgery for high myopia did not affect the prevalence of RRD in operated eyes compared with similar nonoperated eyes, in this long-term study.
