Abstract:
AIM: To compare the refractive prediction accuracy of 7 intraocular lens(IOL)calculation formulas in the cataract eyes with short axial length(AL)at different corneal curvatures and anterior chamber depth(ACD), and analyze relevant influencing factors contributing to prediction errors.METHODS: A retrospective analysis was performed for 125 patients(125 eyes)with a short AL, who received cataract phacoemulsification at Shenyang He Eye Specialist Hospital from November 2020 to December 2021. According to the keratometry(Km), they were divided into low flat Km group(≤45.5 D), medium and high Km group(45.5 D
