PURPOSE: To determine the accuracy of intraocular lens (IOL) power calculations in eyes with high myopia and to suggest adjusted constants for these cases.
METHODS: Patients with high myopia having phacoemulsification with implantation of an AcrySof MA60MA IOL (power range + 5.00 to - 5.00 diopters [D]) were evaluated. Optical biometry (IOLMaster) and IOL calculations were performed before and after IOL implantation. Because of different optic principal planes of negative-diopter and positive-diopter IOLs, separate constants were calculated for these groups.
