摘要: 有效晶状体位置(effective lens position,ELP)在不同人工晶状体(intraocular lens,IOL)屈光度计算公式(如Holladay、SRK/T、Haigis、Hoffer Q、Olsen、Barrett Universal I公式等)中预测方法不同,其准确性也不尽相同。并且ELP在白内障术后是一个动态变化过程,受到多种因素的影响,比如IOL的材料和形状,撕囊口的形状和大小,撕囊的方法,患者本身的情况等。(国际眼科纵览,2021, 45:409-414)

Abstract: The prediction method of effective lens position (ELP) in different intraocular lens (IOL) calculation formulas (such as Holladay, SRK/T, Haigis, Hoffer Q, Olsen, Barrett Universal I formula, etc.) is different, and its accuracy is also different. In addition, ELP is a dynamic process after cataract surgery, which is affected by many factors, such as the material and shape of IOL, the shape and size of capsulorhexis, the method of capsulorhexis, the condition of the patient and so on.(Int Rev Ophthalmol, 2021, 45: 409-414)

Key words: cataract, effective lens position, intraocular lens
