概括

在90岁以上的老年患者中,SRK/T,Barrett Universal II和Haigis眼内透镜 (IOL) 功率计算公式显示了类似的折射精度. 生物识别测量的可靠性和手术风险管理是这个年龄组最佳结果的关键.

科学领域:

眼科医生眼科眼科
生物医学工程生物医学工程

背景情况:

白内障手术在老年人群中很常见.
准确的眼内镜 (IOL) 功率计算对于视觉结果至关重要.
老年人 (≥90岁) 对折射预测具有独特的挑战.

研究的目的:

为了比较三种常见的IOL功率计算公式的折射预测精度:SRK/T,Barrett Universal II和Haigis.
为了评估配方的性能,特别是90岁及以上的患者.

主要方法:

对62只年龄≥90岁的白内障手术患者的眼睛进行了回顾性观察性研究.
使用IOL Master 700进行手术前生物识别.
预测的球形等效与术后3个月明显折射的比较,分析平均绝对误差 (MAE) 和根平均平方绝对误差 (RMSAE).

主要成果:

在SRK/T,Barrett Universal II和Haigis公式 (p>0.12) 中没有发现MAE或RMSAE的统计学上显著差异.
巴雷特通用II公式实现了最高比例的眼睛在预测折射的±0.5 D内 (64.5%).
没有特定的生物识别参数被确定为达到 ±0.5 D.内的折射误差的显著预测因素.

结论:

在90岁及以上的患者中,SRK/T,Barrett Universal II和Haigis公式显示了可比的折射预测精度.
在这个老年人群中,折射结果可能更多取决于生物识别数据的准确性和手术风险的最小化,而不是使用特定的IOL功率计算公式.

Focusing of Light in the Eye

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
