To objectively evaluate the rotational stability, refractive predictability, and visual outcomes of toric EVO ICL using automated infrared retinal retroillumination imaging. Setting/Venue: The research was conducted in a specialized ophthalmic surgery center. Design: Longitudinal analytical prospective study. The methodology included preoperative and postoperative assessments of visual acuity, subjective refraction, corneal topography, and anterior segment OCT. The implantation and alignment process utilized advanced digital centration techniques. Postoperative evaluations were conducted at 1 and 3. The study found a mean incision surgically induced astigmatism (SIA) of 0.32 D, and a refractive SIA average of 2.02 D, closely matching the preoperative refractive astigmatism (target-induced astigmatism-TIA) mean of 2.07 D, resulting in a correction index (CI) of 0.96. Rotational stability was high, with 72% of lenses showing less than 5° rotation and 96% under 10° at the 1-month follow-up. No significant correlations were observed between lens rotation and postoperative vault size or horizontal compression, indicating independent factors. The discrepancy between theoretical and observed rotations suggested that the calculation method slightly underestimated actual rotation, which did not significantly affect visual outcomes. Graphical analysis demonstrated minimal impact of lens rotation on uncorrected distance visual acuity (UDVA), confirming the procedure's efficacy and safety. : Toric EVO ICL implants provide high rotational stability, excellent refractive predictability, and satisfactory visual outcomes. The study underscores the importance of precise implantation and the minimal influence of lens rotation on postoperative refractive errors.
使用自动红外视网膜后照成像客观评估散光型EVO ICL的旋转稳定性、屈光预测性和视觉效果。设置/地点：该研究在一家专业眼科手术中心进行。设计：纵向分析前瞻性研究。方法包括术前和术后对视力、主观验光、角膜地形图和眼前节光学相干断层扫描（OCT）的评估。植入和对准过程采用了先进的数字对中技术。术后在1个月和3个月进行评估。研究发现手术诱导散光（SIA）的平均切口为0.32 D，屈光性SIA平均为2.02 D，与术前屈光性散光（目标诱导散光-TIA）的平均2.07 D密切匹配，校正指数（CI）为0.96。旋转稳定性较高，在1个月随访时，72%的晶状体旋转小于5°，96%小于10°。未观察到晶状体旋转与术后房拱大小或水平压迫之间存在显著相关性，表明为独立因素。理论旋转与观察到的旋转之间的差异表明计算方法略微低估了实际旋转，但这并未对视觉效果产生显著影响。图形分析表明晶状体旋转对未矫正远视力（UDVA）的影响最小，证实了该手术的有效性和安全性。结论：散光型EVO ICL植入物具有高旋转稳定性、出色的屈光预测性和令人满意的视觉效果。该研究强调了精确植入的重要性以及晶状体旋转对术后屈光不正的影响极小。
