摘要:
目的：观察Toric人工晶体(IOL)在老年性白内障伴角膜散光术后疗效及旋转稳定性。方法：收集青岛大学附属医院眼科植入Toric IOL的白内障患者137例156眼。超声乳化手术植入Toric IOL，观察术后至3个月裸眼视力(UCVA)、最佳矫正视力(BCVA),术后残余散光、人工晶状体旋转度及并发症，分析术后疗效。结果：超声乳化术后3个月，90.4%的患者术眼裸眼视力 ≥ 0.5，视力提高显著，患眼的散光度从术前的(1.89 ± 0.54) D降至(0.41 ± 0.29) D。术后3个月与术后第1天比较，IOL旋转平均为(2.76 ± 0.32)˚。结论：Toric IOL具有良好的视力及散光矫正效果和旋转稳定性，为治疗角膜散光提供了一种安全，有效，稳定的治疗方法。
Objective: To study the clinical effect and stability of astigmatism and aix after Toric IOL implanta-tion in age-related cataract. Methods: This study included 137 patients (156 eyes) with astigmatism. Toric IOL implantation was adopted in the operation and placed at the target axis. The patients were followed up for 3 months. The uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), postoperative residual astigmatism, toric IOL axis and complications were measured. Results: At 3 months following surgery, 90.4% of eyes showed the 0.5 or better in UCVA. The mean preoperative corneal astigmatism was (1.89 ± 0.54) D and the postoperative residual astigmatism was (0.41 ± 0.29) D. The mean rotation of toric IOL was (2.76 ± 0.32)˚ degrees after postoperation 1 day. Conclusion: Toric IOL allow patients the better UCVA, good rotational stability and effective in the correct of C. The Toric IOL implantation can be a good option for cataract patients with corneal astigmatism.
