Abstract
Cataract operation has evolved from pure vision improvement toward the optics for reducing refractive errors.The main factor affecting naked vision of postoperative cataract surgery is cornea astigmatism.To correct cornea astigmatism and decrease surgically induced astigmatism are required for resolving problems of post cataract operative refraction and improving visual acuity.The research progress of reducing and correcting astigmatism after cataract extraction was summarized in this paper.
