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
