PURPOSE

To compare the efficacy and rotational stability after implantation of two types of toric implantable collamer lenses (Toric ICL™(TICL);V4 and V4c, STAAR Surgical Co.).

STUDY DESIGN

Retrospective case series.

METHODS

This retrospective study evaluated total 48 eyes of 48 patients who underwent the implantation with V4 and V4c TICL with a central hole; A twenty-four eyes of 24 patients with V4 TICL and 24 eyes of 24 patients with V4c TICL with a central hole. Visual acuity, manifest refraction, and intraocular pressure were evaluated before and after surgery. Rotational stability (disparity between the intended axis and achieved axis) was assessed in both groups using digital anterior segment photographs, and vector analysis was also performed.

RESULTS

Uncorrected visual acuity improved in both groups without significant difference (P = .111). There were no statistical differences between two groups in postoperative SE and cylindrical errors (P = .067 and .384, respectively). The mean value of rotation was 4.17±3.31° and 3.39±2.36° in the V4 and V4c TICL groups, respectively without significant difference (P = .364). Vector analysis of astigmatic correction showed no significant diffrence between two groups.

CONCLUSION

V4 and V4c TICL have similar efficacy with regard to visual acuity and refractive outcomes and rotational stability.

目的

比较两种类型的有晶体眼人工晶体（Toric ICL™(TICL);V4和V4c，STAAR Surgical Co.）植入后的疗效和旋转稳定性。

研究设计

回顾性病例系列。

方法

本回顾性研究评估了48例患者的48只眼睛，这些患者接受了带中心孔的V4和V4c TICL植入手术；其中24例患者的24只眼睛植入V4 TICL，24例患者的24只眼睛植入带中心孔的V4c TICL。在手术前后评估视力、显验光和眼压。使用数字眼前节照片评估两组的旋转稳定性（预期轴与实际轴之间的差异），并进行矢量分析。

结果

两组的未矫正视力均有改善，差异无统计学意义（P = 0.111）。两组术后球镜等效度和柱镜误差无统计学差异（分别为P = 0.067和0.384）。V4和V4c TICL组的平均旋转值分别为4.17±3.31°和3.39±2.36°，差异无统计学意义（P = 0.364）。散光矫正的矢量分析显示两组之间无显著差异。
