Modified Scleral Flap Incision to Reduce Corneal Astigmatism after Intraocular Lens Implantation

摘要

Purpose:To investigate a simple method during extracapsular cataract extraction with posteior chamber intraocular lens implantation in order to reduce surgically induced corneal astig-matism.Methods:A modified scleral flap incision was used in the extracapsular cataract extraction with intraocular lens implantation and the postoperative changes in conreal astigmatism was observed.Results:The peak value of postoperative corneal astigmatism was3.60D,and the corneal astigmatism regression was 2.11D,surgically induced astigmatism was less significant in modified scleral flap incision group than that in convention-al limbal incison group(P<0.05).Conclusions:The modified scleral flap inciston is an ideal incision for cataract ex-traction with intraocular lens implantation when phacoemulsifier is not avaliable.Eye Science1995;11:136-139.
