The aim of this study was to determine the range of ametropias encountered by using the computerized Ophthasonic A-Scan. The SRK formula was used to compute the IOL power using axial length and keratometry as inputs. The accuracy of prediction of IOL power was calculated by noting the disparity between the expected post-operative refraction and the actual refraction obtained after one and a half months of IOL implantation. The results obtained were encouraging; the maximum deviation from the expected result being +/- 3.2 D. |
