Purpose

This study sought to compare the postoperative visual outcomes of toric implantable collamer lens (T-ICL) with toric Artiflex (T-Artiflex) lenses.

Design

Alternating treatment, contralateral eye matched clinical study.

Methods

This study compared 82 eyes of 41 patients with T-ICL lenses in one eye and toric Artiflex implantation in the contralateral eye to correct myopic astigmatism. Safety, efficacy, predictability, astigmatic vector changes, contrast sensitivity, endothelial cell count, and possible adverse events were assessed at least 12 months postoperatively.

Results

After a mean follow-up of 12 months, the safety index was mean 1.40 ± 0.70 in the T-ICL group and 1.20 ± 0.21 in the T-Artiflex group. Furthermore, their mean efficacy indexes were 1.24 ± 0.42 and 1.08 ± 0.23, respectively (P = .029). A total of 39 eyes (95%) in the T-ICL group and 41 eyes (100%) in the T-Artiflex group were within ±1.00 diopter (D) of emmetropia and 33 eyes (80%) and 34 eyes (83%) were within ±0.5 D of emmetropia, respectively. Vector analysis revealed mean index of success as large as 0.25 ± 0.22 in the T-ICL group and 0.24 ± 0.15 in the T-Artiflex group. Postoperative contrast sensitivities were equal in both groups under mesopic conditions for any given spatial frequency. There was an endothelial loss of 2.18% and 1.95% in the T-ICL and T-Artiflex groups, respectively. There were no significant complications in any of the groups.

Conclusions

Both lenses showed promising results in terms of safety, efficacy, and predictability for correction of myopic astigmatism. As shown in this paired-eye study, most outcomes were almost identical, and neither of these lenses were clinically superior to the other.

在视觉结果方面比较Toric植入式Collamer晶状体和Toric Artiflex晶状体IOL：一对对侧眼研究。

目的

这项研究试图比较复曲面植入式角膜接触镜（T-ICL）与复曲面Artiflex（T-Artiflex）镜片的术后视觉效果。

设计

交替治疗，对侧眼球配合临床研究。

方法

这项研究比较了41例T-ICL晶状体患者的82眼，其中一只眼在对侧眼中植入了复曲面Artiflex，以矫正近视散光。术后至少12个月评估安全性，疗效，可预测性，散光载体变化，对比敏感性，内皮细胞计数和可能的不良事件。

结果

在平均随访12个月后，T-ICL组的安全指数为1.40±0.70，T-Artiflex组的安全指数为1.20±0.21。此外，它们的平均功效指数分别为1.24±0.42和1.08±0.23（P = .029）。T-ICL组共有39眼（95％），T-Artiflex组共有41眼（100％）处于正视眼的±1.00屈光度（D）以内; 33眼（80％）和34眼（83） ％）分别在正视眼的±0.5 D之内。向量分析显示，T-ICL组的平均成功指数高达0.25±0.22，T-Artiflex组的平均成功指数为0.24±0.15。对于任何给定的空间频率，在中观条件下两组的术后对比敏感度均相等。T-ICL和T-Artiflex组的内皮损失分别为2.18％和1.95％。任何一组均无明显并发症。

结论

在矫正近视散光的安全性，有效性和可预测性方面，这两款镜片均显示出令人鼓舞的结果。如该双眼研究中所示，大多数结果几乎相同，并且这些镜片在临床上都没有一个优于另一个。
