Abstract

Background

To compare the visual outcomes and the accuracy of three axial marking techniques for toric intraocular lenses (IOLs): manual marking, the CALLISTO eye image-guided system and femtosecond laser-assisted capsulotomy marking.

Methods

A total of 105 eyes of 105 patients were enrolled in this retrospective comparative study. According to different axial marking methods, patients were assigned to the manual marking group (MM group), CALLISTO Eye image-guided system group (CE group) and femtosecond laser-assisted capsulotomy marking group (CM group). Uncorrected distant visual acuity (UCDVA), best corrected distant visual acuity, residual astigmatism, toric IOL misalignment, and modulation transfer function were measured and compared preoperatively and one month and three months postoperatively.

Results

Postoperative UCDVA and residual astigmatism were significantly lower in the CM group than in the MM group and CE group both at one month and three months postoperatively. IOL misalignment in the CM group was significantly less than that in the other two groups, and the CE group also performed better than the MM group. The AR values in the CE group and CM group were significantly higher than those in the MM group. Further correlation analysis found that postoperative UCDVA was positively correlated with residual astigmatism and IOL misalignment and negatively correlated with AR value. Postoperative residual astigmatism was positively correlated with IOL misalignment and negatively correlated with AR value.

Conclusion

Femtosecond laser-assisted capsulotomy marking provided the best visual outcomes and accurate alignment for toric IOLs. The CALLISTO eye image-guided marking performed moderately but slightly better than manual marking.

人工、图像引导和飞秒激光辅助标记技术在环形人工晶状体对准中的比较。

背景：比较人工标记、CALLISTO眼睛图像引导系统和飞秒激光辅助囊膜切开术三种环型人工晶状体（iol）轴向标记技术的视觉效果和准确性。方法：对105例患者的105只眼进行回顾性比较研究。根据轴向标记方式的不同，将患者分为手动标记组（MM组）、CALLISTO Eye图像引导系统组（CE组）和飞秒激光辅助囊膜切开术标记组（CM组）。测量术前、术后1个月、3个月未矫正远视力（UCDVA）、最佳矫正远视力、剩余散光、环形人工晶状体错位、调制传递函数并进行比较。结果：CM组术后1个月和3个月的UCDVA和残余散光明显低于MM组和CE组。CM组的IOL错位明显少于其他两组，CE组也优于MM组。CE组和CM组的AR值明显高于MM组。进一步相关分析发现，术后UCDVA与残留散光、IOL错位正相关，与AR值负相关。术后残留散光与人工晶状体错位正相关，与AR值负相关。结论：飞秒激光辅助囊膜切开术对人工晶状体有较好的视觉效果和准确对准效果。CALLISTO眼睛图像引导标记表现一般，但略好于手动标记。
