【摘要】：目的:通过一种高精度方法评价AcryS of散光型人工晶体的旋转稳定性。方法:收录90例年龄相关性白内障伴中、高度散光患者(104眼),施行白内障超声乳化联合AcryS of散光型人工晶体植入术。患者在规定的复查时间接受必要的检查。通过KR-1W视觉质量分析仪检测AcryS of散光型人工晶体的稳定性。观察指标包括裸眼远视力(UDVA)、最佳矫正远视力(CDVA)以及显然验光结果。通过配对T检验及ANOVA检验分析结果。结果:研究共纳入104眼,从术前检查至最后一次术后复查持续24个月。7次复查时间点观察到AcryS of散光型人工晶体的位置没有显著变化,P=0.863;所有患者的裸眼远视力(logM AR,4.39±0.27至4.77±0.22;P0.001)、最佳矫正远视力(logM AR,4.54±0.25至4.93±0.14;P0.001)以及显然验光[度(D),-1.27±0.98至-0.97±0.71,P=0.003]均有显著改善。术后调制传递函数(MTF)较术前提高。结论:研究显示AcryS of散光型人工晶体具有很好的旋转稳定性。该种人工晶体可以减少显然验光的柱镜度数、提高视力并改善视力相关的生活质量。
[Abstract]:Objective: to evaluate the rotation stability of AcryS of astigmatism intraocular lens by a high precision method. Methods: eyes of 90 age-related cataract patients with high astigmatism were treated with phacoemulsification combined with AcryS of astigmatism intraocular lens implantation. The patient is subject to the necessary examination at the prescribed time of review. The stability of AcryS of astigmatism intraocular lens was tested by KR-1W visual quality analyzer. The parameters included open-eye distant vision (UDVA), best corrected far vision (CDVA) and apparent optometry. The results were analyzed by paired T test and ANOVA test. Results: 104 eyes were included in the study. The results showed that the position of AcryS of astigmatism intraocular lens did not change significantly from preoperative examination to the last postoperative reexamination for 24 months, and the position of AcryS of astigmatism intraocular lens was not changed significantly (P < 0. 863). The uncorrected far visual acuity (logM AR,4.39 卤0.27-4.77 卤0.22p0.001) and the best corrected far visual acuity (logM AR,4.54 卤0.25-4.93 卤0.14) were obtained in all patients. There were significant improvements in optometry [degree (D),-1. 27 卤0. 98 to-0. 97 卤0. 71 P0. 003]. The postoperative modulation transfer function (MTF) was higher than that before operation. Conclusion: AcryS of astigmatism intraocular lens has good rotation stability. This kind of IOL can reduce the apparent optometry degree, improve vision and improve the quality of life associated with vision.
