摘要

目的：评价环形人工晶状体植入术治疗白内障合并角膜不对称散光患者的疗效和安全性，并评价其术后视力质量。方法：在本前瞻性病例系列中，对中国温州医科大学眼科医院角膜地形图鉴定为白内障、角膜散光> 0.75 (D)和不对称中心散光的26只眼进行检查。所有的参与者都在医院接受了人工晶状体植入术。主要指标包括未矫正视力（UCVA）、最佳矫正视力（BCVA）、剩余散光、预测误差和人工晶状体旋转程度。结果：术后UCVA和BCVA均有明显改善，UCVA从0.70（0.40,0.93）提高到0.018 (0.05,0.30)logMAR， BCVA从0.50（0.38,0.70）提高到0.00 (0.0,0.10)logMAR （P < 0.001）。术前预测的球当量与术后实际的球当量呈正相关（= 0.7682），所有病例的球当量预测误差均在±1.00 D以内。术后残余散光≤1.00 D 25眼（96%），环形人工晶状体平均旋转度2.46°±2.08°。视觉质量客观评价显示，非对称角膜散光患者在瞳孔直径为2mm的条件下，术后视觉质量较好，随着瞳孔直径的增大，视觉质量明显下降。结论：环形人工晶状体植入术是一种安全有效的治疗非对称性角膜散光白内障的方法。术前对这些患者的球等效和残余散光的预测是准确可靠的，导致良好的视力结果和术后视觉质量的提高。

Efficacy of toric intraocular lens implantation in individuals with cataracts and asymmetric corneal astigmatism

Objective

The objective of this study is to evaluate the efficacy and safety of toric intraocular lens (IOL) implantation in individuals with cataracts and asymmetric corneal astigmatism and to assess their postoperative visual quality.

Methods

In this prospective case series, 26 eyes of individuals with cataracts and corneal astigmatism > 0.75 diopters (D) and asymmetric central astigmatism as identified through corneal topography were examined at the Eye Hospital of Wenzhou Medical University, China. All participants underwent toric IOL implantation surgery at the hospital. The primary outcome measures included uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), residual astigmatism, prediction error, and the degree of IOL rotation.

Results

Both postoperative UCVA and BCVA improved significantly, with UCVA increasing from 0.70 (0.40, 0.93) to 0.018 (0.05, 0.30) logMAR, and BCVA improving from 0.50 (0.38, 0.70) to 0.00 (0.0, 0.10) logMAR (P < 0.001). A strong positive correlation was observed between the preoperative predicted spherical equivalent and the postoperative actual spherical equivalent (= 0.7682), with prediction errors for the spherical equivalent within ± 1.00 D in all cases. Postoperative residual astigmatism was ≤ 1.00 D in 25 eyes (96%), and the mean degree of toric IOL rotation was 2.46° ± 2.08°. Objective assessments of visual quality showed that patients with asymmetric corneal astigmatism achieved better postoperative visual quality under miotic conditions (pupil diameter: 2 mm), with a significant decrease in visual quality as pupil diameter increased.

Conclusion

The results of this study demonstrated that toric IOL implantation surgery is an effective and safe treatment for selected individuals with cataracts and asymmetric corneal astigmatism. Preoperative predictions for spherical equivalent and residual astigmatism in these patients proved accurate and reliable, resulting in favorable visual outcomes and enhanced visual quality post-surgery.
