Advance in refractive power prediction in cataract patients with high myopia

Abstract

Current formulas tend to select intraocular lens with insufficient power for these patients, resulting in postoperative hyperopia. In addition to the traditional methods to address this problem such as reserving a myopic power in the power calculation, several more accurate and effective solutions have been suggested, including adjusting the axial lengths, using new formulas, and applying intraoperative refractive biometry. This paper will focus on the postoperative refractive error in highly myopic eyes after phacoemulsification and intraocular lens implantation and illustrate the progress of existing solutions.
