在C-循环纹触觉眼内眼镜 (IOL) 提供卓越的旋转稳定性和高旋转风险的眼睛的斜视纠正. 这种托里克IOL的性能优于板状触觉设计,即使是带有囊张力环 (CTR).
科学领域:
- 眼科医生 眼科 眼科
- 生物医学工程 生物医学工程
- 医疗器械 医疗器械
背景情况:
- 在白内障手术期间,托里克眼内透镜 (IOL) 纠正了白内障手术期间的.
- 确保眼镜的旋转稳定性对于保持正至关重要.
- 具有较大的白至白 (WTW) 距离的眼睛具有更高的内视镜旋转风险.
研究的目的:
- 为了比较C-循环纹触觉光 IOL与板式触觉光 IOL的旋转稳定性和性校正.
- 为了评估囊张力环 (CTR) 对板状触角体内膜眼镜的性能的影响.
- 为了评估白内障眼睛中因WTW距离大而具有高旋转风险的IOL性能.
主要方法:
- 一个回顾性队列研究,涉及90个白内障眼睛,WTW>11.8毫米.
- 眼睛被植入了C-循环纹触觉眼镜 (ZCU组) 或板式触觉眼镜 (709组),有或没有CTR.
- 在手术后一个月内测量了IOL旋转和残留形.
主要成果:
- 与板式触觉IOL相比,C-循环纹触觉IOL (ZCU组) 的旋转稳定性 (1.87°) 显著更好 (4.63°与CTR,4.13°没有CTR;P <0.05).
- 集团ZCU还实现了显著较低的残留光 (0.36 D) 与板状触觉IOL (0.54 D与CTR,0.65 D没有CTR;P <0.05).
- WTW距离在板状触角组中与IOL旋转正相关,但在C-循环组中没有.
结论:
- 在WTW距离较长的眼睛中,C-循环纹触觉 IOL提供了卓越的旋转稳定性.
- 这种托里克内膜眼镜设计还提供了更好的性纠正与板状触觉设计相比,无论CTR使用.
- 这些发现表明,C环设计可以减轻与大眼尺寸相关的旋转风险.
