Abstract

Corneal astigmatism after cataract surgery: The effect of electrocautery. We analized the effect of electrocautery on corneal astigmatism after cataract operation. Phacoemulsification and PCL implantation were performed by standard technique with 5.5 mm scleral pocket incision and sutureless method. In electrocautery group. scleral cautery was done at the site of scleral pocket incision and in no electrocautery group, cautery was not performed. 53 eyes(electrocautery group) showed slight against the rule change(-0.26D +/- 0.72) of corneal astigmatism, while 24 eyes(no electrocautery group) showed slight with the rule change(+0.36D +/- 0.67) of corneal astigmatism at post-operative 2 months. And these difference was statistically significant.(Student's t-test; p=0.019) Therefore, we found the scleral electrocautery at the incision site during cataract surgery induced slight against the rule change of corneal astigmatism.
