Abstract
Cataract surgery has entered the era of refractive surgery, and patients have higher requirements for visual quality. Astigmatism correction in cataract surgery is increasingly valued, but the astigmatism correction results are not ideal, and the principles of corneal astigmatism correction are not well established. In this article, the issues including how to dialectically decide to treat the corneal astigmatism or not, how to choose the corneal astigmatism estimating method and the calculation formula for astigmatism correction, the range of corneal astigmatism suitable for applying multifocal intraocular lens, selection of intraoperative corneal astigmatism correction method, etc., were discussed based on relevant authoritative guidelines, expert consensus and literatures, and corresponding suggestions were given.
