| Abstract |
|
The short-term changes in corneal astigmatism and visual acuity after phacoemulsification with foldable intraocular lens implantation through a 3.2mm temporal clear corneal incision (group 1) and these through a 3.2mm superior scleral incision(group 2) were compared.Corneal topographic measurement were obtained preoperatively and at poeroperative 1 day, 2 months. Scalar and vector astigmatism in group 1 and group 2 were compared by simple subtraction method, Cravy method and Holladay method.The surgically induced astigmatism in both groups showed no difference in with-the-rule change(0.57D-0.10D) and uncorrected visual acuity also showed no different results in both groups. In the group 1, preoperative with-the-rule astigmatism were changed 0.18D toward with-the rule and preoperative against-the -rule astigmatism were shifted 0.64D toward with-the-rule direction.Conclusively. both incisions offered satisfactory short-term astigmatic results and rapid visual rehabilitation and change of astigmatism in the wyws with preoperative against-the-rule astigmatism was greater than those with peroperative with-the-rule astigmatism in temporal clear corneal incision group. |
