To compare the vault performance between implantable collamer lens (ICL) V4c and Toric ICL (TICL) V4c after implantation and to investigate the affecting factors.
Sixty-eight eyes from 34 patients with myopia or myopia astigmatism who underwent implantation of TICL in one eye (group A) and identically sized ICL (group B) in the contralateral eye were included. Mean follow-up time were 7.58 ± 1.63 months (range: 6-10 months). Vault was compared between the two groups and correlations between vault and age, preoperative ocular biometric measurements were analysed. Generalized estimating equation (GEE) model of postoperative vault adjusting for within-patient intereye correlations was performed.
The safety indices were 1.27 and 1.35, and the efficacy indices were 1.20 and 1.24 for groups A and B, respectively. Vault of TICL was significantly higher than that of ICL (554.11 ± 219.36 μm vs 449.70 ± 172.47 μm, P < 0.001). The difference between ICL/TICL size and WTW (size-WTW) and STS (size-STS), anterior chamber depth and pupil diameter (PD) were positively correlated with vault. Patient age and clear lens rise measured by Pentacam were negatively correlated with vault. Results of GEE model showed preoperative PD, age, cylindrical power of TICL and size-WTW were influencing factors for postoperative vault.
Vault after TICL implantation is higher than that with ICL. PD, age, cylindrical power of TICL and size-WTW could affect postoperative vault.
比较植入可植入式胶原晶状体（ICL）V4c和散光型ICL（TICL）V4c后房的表现，并研究其影响因素。
纳入34例近视或近视散光患者的68只眼，其中一只眼植入TICL（A组），对侧眼植入相同大小的ICL（B组）。平均随访时间为7.58±1.63个月（范围：6 - 10个月）。比较两组之间的后房情况，并分析后房与年龄、术前眼部生物测量值之间的相关性。采用广义估计方程（GEE）模型对患者眼内相关性进行术后后房调整。
A组和B组的安全指数分别为1.27和1.35，疗效指数分别为1.20和1.24。TICL的后房明显高于ICL（554.11±219.36μm对449.70±172.47μm，P < 0.001）。ICL/TICL大小与白到白距离（大小 - WTW）和巩膜隧道长度（大小 - STS）、前房深度和瞳孔直径（PD）之间的差异与后房呈正相关。患者年龄和Pentacam测量的晶状体提升与后房呈负相关。GEE模型结果显示，术前PD、年龄、TICL的柱镜度数和大小 - WTW是术后后房的影响因素。
TICL植入后的后房高于ICL。PD、年龄、TICL的柱镜度数和大小 - WTW可影响术后后房。
