Abstract

Purpose: To assess rotational stability and refractive outcomes of a new toric hydrophobic acrylic intraocular lens (IOL).

Design: Single-center, prospective, interventional clinical trial.

Methods: A total of 130 eyes of 82 patients with age-related cataract and total corneal astigmatism of greater than 1.0 diopters (D) received a hydrophobic acrylic toric IOL Clareon CNW0T3-9. Baseline measurement for rotational stability evaluation was performed at the end of surgery (EOS), with the patient still supine on the operating table, using non-movable vessels as reference landmarks. Postoperative retroillumination pictures were taken at 1 h, 1 week, 1 month and 4-6 months postoperatively. Subjective manifest refraction was assessed at the 6 months follow-up visit.

Results: Final results were obtained in 126 eyes of 80 patients. Mean absolute rotation from EOS to 6 months was 1.33 ± 2.00 [0.01, 19.80] degrees. Rotational stability values from EOS to 1 h, 1 h to 1 week, 1 week to 1 month and 1 month to 6 months were 0.86 ± 0.82 [0.00, 3.90], 1.06 ± 1.94 [0.00, 19.45], 0.47 ± 0.42 [0.00, 2.03] and 0.38 ± 0.40 [0.00, 2.56] degrees. Mean preoperative corneal astigmatism was 1.78 ± 0.83 [1.00, 4.76] D which changed to a mean postoperative refractive astigmatism of 0.33 ± 0.27 [0.00, 1.25] D at 6 months.

Conclusion: The Clareon toric IOL presented very good rotational stability with a mean absolute rotation below 1.4° from EOS to 6 months. Only two IOLs rotated more than 5° with none of them requiring repositioning surgery. Refractive outcomes were satisfying with a mean residual refractive astigmatism below 0.50 D.

新型疏水性丙烯酸散光眼内透镜的旋转稳定性和屈光效果。

目的：评估新型散光疏水丙烯酸眼内透镜（IOL）的旋转稳定性和屈光效果：单中心、前瞻性、介入性临床试验：82名患有老年性白内障且角膜散光大于1.0屈光度（D）的患者共130只眼睛接受了疏水性丙烯酸散光人工晶体Clareon CNW0T3-9。旋转稳定性评估的基线测量是在手术结束（EOS）时进行的，当时患者仍仰卧在手术台上，使用不可移动的血管作为参考地标。分别在术后 1 小时、1 周、1 个月和 4-6 个月拍摄术后反照照片。术后 6 个月随访时评估主观屈光度：80名患者的126只眼睛获得了最终结果。从EOS到6个月的平均绝对旋转度为1.33 ± 2.00 [0.01, 19.80]度。从EOS到1小时、1小时到1周、1周到1个月和1个月到6个月的旋转稳定值分别为0.86 ± 0.82 [0.00, 3.90]、1.06 ± 1.94 [0.00, 19.45]、0.47 ± 0.42 [0.00, 2.03]和0.38 ± 0.40 [0.00, 2.56]度。术前平均角膜散光度数为 1.78 ± 0.83 [1.00, 4.76] D，术后 6 个月平均屈光散光度数为 0.33 ± 0.27 [0.00, 1.25] D：Clareon散光人工晶体的旋转稳定性非常好，从EOS到6个月的平均绝对旋转角度低于1.4°。只有两个人工晶体旋转超过 5°，没有一个需要重新定位手术。屈光结果令人满意，平均残余屈光散光低于 0.50 D：试验注册：于 2022 年 5 月 17 日在 Clinicaltrials.gov NCT03803852 注册。
