| Abstract |
|
To evaluate surgically induced astigmatism for 6 months following 3.2mm scleral tunnel incision cataract surgery according to incision site we divided 115 patients(124 eyes) into superior incision group 1 (58 eyes) and superotemporal incision group 2 (66 eyes). Each group was classified into 3 cases according to preoperative astigmatism. Postoperative astigmatic changes by vector method were 0.40 diopter(D) against-the-rule astigmatism(ATR) in group 1, 0.25 D ART in group 2 at 6 months and there was no difference between two groups(P>0.05). In the preoperative with-the-rule astigmatic cases, postoperative astigmatic changes were 0.56 D ART in group 1, 0.38 D ATR in group 2, in the preoperative against-the-rule astigmatic cases, postoperative astigmatic changes were 0.25 D ART in group 1, 0.12 D ART in group 2, in the preoperative no astigmatic cases, postoperative astigmatism changes were 0.53 D ATR in group 1, 0.25D ART in group 2 at 6 months. There was no significant difference between two groups in postoperative astigmatic changes(P>0.05) and corneal astigmatisms were stabilized after 2 months postoperatively in both groups(P<0.05). |
