Abstract：Objective: To determine the incidence of unplanned reoperation following implantable collamer lens (ICL) implantation in the early postoperative period and analyze the reasons, treatment and prognosis for reoperation. Methods: In this retrospective clinical study, all patients undergoing ICL implantation at Peking Union Medical College Hospital between April 2020 and March 2021 were reviewed. A total of 1483 cases of ICL implantation operations were performed. The reasons, treatment and prognosis for unplanned reoperation were analyzed. The eyes that had unplanned reoperation because of abnormal vault were divided into low vault group and high vault group. Kruskal Wallis test was used to compare the age and diopters of the eyes in each group. Variance analysis was used to compare the white to white distance, angle to angle distance, anterior chamber depth, lens rise, lens thickness, axial length and vault of the eyes in each group. t test was used to compare the vault, astigmatism and uncorrected visual acuity before and after reoperation. Results: Thirty-seven eyes (2.49%) underwent unplanned reoperation within two weeks after the ICL implantaion.Among them, ICL rotation was performed on 34 eyes and ICL exchange on 3 eyes. The most common reasons for reoperation were abnormal vault and residual astigmatism. The reasons for the ICL rotation were high vault (13 eyes), residual astigmatism (11 eyes), and low vault (10 eyes). The reasons for the 3 eyes of ICL exchange were low vault (2 eyes) and high vault (1 eye). After reoperation, the vault of the high vault group was decreased from 974±174 μm to 691±120 μm, the vault of the low vault group was increased from 174±49 μm to 388±78 μm, the astigmatism of the residual astigmatism group was drecreased from 1.34±0.34 D to 0.39±0.26 D, and all the changes were statistically significant (P<0.001). No complications were encountered during reoperation. Conclusions: Abnormal vault and residual astigmatism were the main reasons for unplanned reoperation. The desired vault and diopter could be achieved through reoperation.
