在当今的现代白内障和屈光手术中，获得精确的术后目标屈光是至关重要的。鉴于接受优质人工晶状体植入术的患者数量不断增加，患者的期望持续上升。为了满足患者更高的期望，至关重要的是要高度重视患者选择、准确的角膜曲率测量和生物测量读数，以及应用正确的人工晶状体度数公式和优化的晶状体常数。本文回顾了临床生物测量和人工晶状体屈光力计算领域的最新进展。最近开发的低相干反射光学生物测量技术可与旧的超声波生物测量和角膜曲率测量技术相媲美。此外，新的 IOL Master 软件升级提高了再现性并增强了信号采集。此外，现代晶状体屈光力公式目前可以更准确地确定有效晶状体位置和眼内晶状体屈光力预测曲线的形状。为了达到目标屈光度，精确的生物识别测量势在必行。了解当前可用的生物测量设备的优点和局限性，可以防止高变异性和不准确性，最终确定屈光结果。
Obtaining precise post-operative target refraction is of utmost importance in today’s modern cataract and refractive surgery. Given the growing number of patients undergoing premium intraocular lens implantations, patient expectation continues to rise. In order to meet heightened patient expectations, it is crucial to pay utmost attention to patient selection, accurate keratometry and biometry readings, as well as to the application of correct intraocular lens power formula with optimized lens constants. This article reviews recent advances in the field of clinical biometry and intraocular lens power calculations. Recently developed low-coherence reflectometry optical biometry is comparable to older ultrasonic biometric and keratometric techniques. In addition, the new IOL Master software upgrade has improved reproducibility and enhanced signal acquisition. Further, the modern lens power formulas currently determine the effective lens position and the shape of the intraocular lens power prediction curve more accurately. In order to reach target refraction, precise biometric measurements are imperative. Understanding the strengths and limitations of the currently available biometry devices, allows prevention of high variability and inaccuracy, ultimately determining the refractive outcomes.
