The operating corneoloscope and Terry operative keratometer were used respectively in 29 and 34 eyes during the intraocular lens implanta-tion to measure the corneal astigmatism qualitatively or quantitatively,so that the tension of incision closure could be adjusted.The surgically induced astig-matism in qualitative group two weeks after the operation was 3.5±1.70 D and that in quantitative group was 2.56±1.60 D.There were 55.17％ and 38.24 ％ of the eyes with over 2.00 D corneal astigmatism in qualitative and quan-titative group two months after the surgery.The astigmatism of both groups at the early stage after the operation was significantly lower than that of the con-trol group (p＜0.05).Argon laser,Nd:YAG laser or razor-blade were used to cut 1 to 3 limbal sutures in 64 eyes with over with-the-rule astigmatism 2.25 D at the early stage (2 months) after the operation.One hour after suture cut-ting,the with-the-rule corneal astigmatism reduced significantly with an aver-age of 2.61 D.The astigmatism c
