As the number of cataract patients with high myopia increases, and the cataract surgery shifts from a rehabilitation procedure to a refractive procedure, achieving a good postoperative visual acuity has been the target of cataract patients with high myopia.Because of inaccurate axial length measurement, unpredictable effective lens position and improper selection of intraocular lens (IOL) calculation formulas, the precision of refractive prediction in cataract patients with high myopia remains low, which affects the visual acuity and satisfaction of patients.With the development of IOL calculation formulas, SRK/T, Holladay1 and other thin-lens vergence formulas have been modified in axial length, corneal curvature and other parameters, and the thick-lens vergence formulas such as Barrett Universal Ⅱ have been widely put into use.Meanwhile, new formulas including artificial intelligence-based formulas such as Hill-RBF, ray tracing formulas such as Olsen and OKULIX, and theoretical formulas such as Kane and EVO formulas have been developed.More choices and guarantees are available for refractive prediction after cataract surgery.This paper summarized the optimization and advance of different types of IOL calculation formulas so as to provide different available choices to improve the accuracy of IOL power calculation in cataract patients with high myopia.
