Abstract

Purpose: To evaluate the postoperative vault, haptic position, and axis stability of vertical implantable collamer lens (ICL) implantation.

Setting: Fudan University Eye and ENT Hospital, Shanghai, China.

Design: Prospective.

Methods: This study included patients who underwent ICL implantation. Three months postoperatively, the vault, haptic position, and axis were measured.

Results: Ninety-eight eyes from 98 patients were included. At 3 months postoperatively, the vault was 517.10 ± 200.08 µm in the vertical group and 506.88 ± 204.19 µm in the horizontal group (P = .803). There was a significant difference in the distribution of haptics in the ciliary sulcus (ICS) between the two groups (P = .045). In the vertical group, an average of 0.90 ± 0.83 haptics near the incision and 1.33 ± 0.81 haptics away from the incision were located in the sulcus, showing a significant difference (P = .002). In those undergoing toric ICL implantation, 54% of eyes in the vertical group and 79% in the horizontal group experienced rotation, with a significant difference (P = .042). In the horizontal group, there were significant differences in both the vault and difference value between vertical and horizontal sulcus-to-sulcus (vSTS - hSTS) between the non-rotated and rotated subgroups (P = .019 and P = .035, respectively).

Conclusion: Customized vertical ICL implantation does not affect refractive outcomes and achieves an ideal vault. Situating the haptic near the incision in the ciliary sulcus is relatively more difficult for vertical implantation. Vertical implantation improves ICL stability in patients with a large vSTS - hSTS.

定制垂直可植入术的触觉和轴稳定性。
目的:评价垂直人工晶体(ICL)植入术后的拱顶、触觉位置和轴稳定性。单位:中国上海复旦大学眼科医院。设计:前瞻性。方法:本研究包括接受ICL植入术的患者。术后3个月测量拱顶、触觉位置和轴向。结果:纳入98例患者的98只眼。术后3个月,竖直组和水平组的牙弓长度分别为517.10±200.08µm和506.88±204.19µm (P = 0.803)。两组睫状沟触觉分布差异有统计学意义(P = 0.045)。垂直组位于切口附近的触觉平均为0.90±0.83,远离切口的触觉平均为1.33±0.81,差异有统计学意义(P = 0.002)。环形ICL植入术中,垂直组和水平组的旋转率分别为54%和79%,差异有统计学意义(P = 0.042)。在水平组中,未旋转和旋转亚组在垂直和水平沟-沟(vSTS - hSTS)之间的拱顶和差值均有显著差异(P = 0.019和P = 0.035)。结论:定制垂直ICL植入术不影响屈光效果,达到理想的拱顶。垂直植入术中,植入点位于睫状沟切口附近相对较困难。垂直植入可改善大vSTS - hSTS患者ICL的稳定性。
