Abstract 【Objective】To explore the influencing factors of arch height changes in patients with high myopia after phakic posterior chamber implantable contact lens (PPC-ICL) implantation. 【Methods】Patients with high myopia who underwent PPC-ICL implantation in our hospital from May 2016 to January 2018 were recruited as study subjects, including 56 cases (58 eyes) with high arch height (＞750 μm, the high arch height group) and 64 cases (76 eyes) with low arch height (＜250 μm, the low arch height group). Meanwhile, 140 patients (140 eyes) with normal arch height were selected as the healthy control group. The preoperative related parameters were compared among the three groups. Multivariate regression analysis of arch height changes in patients with high myopia after PPC-ICL implantation was performed. 【Results】There were no significant differences in age, spherical equivalent (SE), height of ciliary processes (T value) and mean keratometry (Km) among the three groups (P>0.05), however, the differences in white-to-white distance (WTW), posterior angle, anterior chamber depth (ACD), horizontal distance of sulcus-to-sulcus (STS), lens thickness (LT), ICL size and axial length (AL) were statistically significant (P<0.05) among groups. Multivariate logistic regression analysis showed that WTW, ACD, horizontal and vertical distance of STS, LT and ICL size were independent influencing factors of abnormal arch height (P<0.05). SE and horizontal distance of STS were independent influencing factors of arch height variation after PPC-ICL implantation (P<0.05). 【Conclusion】The abnormal arch height in high myopia patients after PPC-ICL implantation is related to multiple parameters such as preoperative WTW, ACD, STS, LT and ICL size. The arch height variation is closely related to SE and horizontal distance of STS.
