Abstract

The mean spherical and Cylindrical error in right eye was 1.46 ± 0.94 and 0.83 ± 0.55, with a minimum of 0.25 and 0.25 maximum of 5.50 and 3.75 as assessed by AR without dilatation. The mean spherical and Cylindrical error in Left eye was 1.17 ± 0.91 and 0.87 ± 0.58 with a minimum of 0.12 and 0.25 maximum of 5.00 and 3.75, as assessed by AR without dilatation. Simple Astigmatism was 16% and the remaining 61% had compound astigmatism, as assessed by AR after dilattion. Cylindrical error in right eye was 1.14 ± 0.84 and 0.64 ± 0.53, with a minimum of 0.12 and 0.25 maximum of 4.50 and 4.25 as assessed by AR after dilatation. The mean spherical and Cylindrical error in Left eye was 0.97 ± 0.86 and 0.67 ± 0.55with a minimum of 0.12 and 0.25 maximum of 5.00 and 3.37. With spherical error were 32%, Simple Astigmatism were 27% and the remaining 41% had compound astigmatism, as assessed by PMT.
