| Abstract |
|
Postoperative changes of keratometric astigmatism were analysed in 137 cases of phacoemulsification and foldable silicone posterior chamber lens implantation using clear corneal incision. The subjects were divided into two groups; Group 1 comprised 36 eyes which underwent surgery using a superior approach, Group 2 comprised 101 eyes which underwent surgery using a temporal approach. Surgically induced keratometric astigmatism in Group 1 was -1.14+/-1.02 diopter(D) at one day, -0.98+/-1.03 D at one week, -0.58+/-0.94 D at two months after operation, and in Group 2 was 0.69+/-0.97 D at one day, 0.96+/-1.08 at one week, 0.63+/-0.68 at two months after operation. The difference of absolute astigmatism between two groups was statistically significant(p<0.05) at one day after operation. But there was no statistically significant difference at one week and two months after operation. Temporal incision induced less astigmatism than superior incision temporarily in cataract surgery using clear corneal incision. |
