Progress of IOL calculation formulas for cataract patients with high myopia

Abstract

Cataract with high myopia is a kind of complicated cataract with highly blinding disease. Surgery has always been the only treatment, but there is always a difference between actual postoperative refraction and target refraction. The cataract patients with high myopia have increasing demands for postoperative refractive status and visual quality now. The intraocular lens(IOL)calculation formulas have been updating for higher predictive accuracy. A variety of alternative IOL calculation formulas can be applied to clinical practice. However, there is no consensus on the selection of a more suitable formula for cataract patients with high myopia. Based on the principles and clinical application of different formulas, this paper reviews the development of IOL calculation formulas and research progress of IOL calculation formulas for cataract patients with high myopia, in order to provide reference for clinical application.
