Research progress in residual astigmatism after phacoemulsification cataract extraction and intraocular lens implantation / 中华实验眼科杂志

ABSTRACT

Phacoemulsification cataract extraction and intraocular lens (IOL) implantation has become the mainstream treatment of cataract.But the postoperative residual astigmatism still influences the postoperative uncorrected visual acuity.Reduce residual astigmatism is currently the ophthalmologists' pursuit.The formation of the residual astigmatism is affected by various factors,which mainly associated with preoperative corneal astigmatism and surgically induced astigmatism.Except for the above reasons,residual astigmatism after Toric IOL implantation has its special reasons.Understanding the reasons of formation of residual astigmatism can provide us the methods how to reduce it.This paper reviewed the causes of the residual astigmatism after phacoemulsification cataract extraction and IOL implantation.
