| Abstract |
|
To determine amount of surgically induced outcome of 3.5mm clear corneal incisin, 30 eyes(30 patients) were evaluted retrospectively. Corneal curvature was measured using cmputerized videokeratography, and the induced astigmatism was calculated with using the Holladat-Cravy-Koch formula. The corneal flattening was significantly more prominent at distances of 0.5, 1.5 and 2.5mm along 90-degree meridian and 270 degree meridian at one week 1 month postoperatively but decreased at 6 months. Surgically induced astigmatism was -0.5D at one week, -0.12D at 1 month, and -0.13D at 6 month in groups using keratometry and in group using toography. At 1 month postoeratively surgically induced astigmatism in topography was statically sigmificant(p<0.05). |
