Aim: To Study the changes in corneal higher order aberrations after Aspheric LASIK treatment
Method: A prospective observational study of 100 eyes of 51 patients, with manifest refraction ranges from -1 to -10 D sphere and -0.5 to -4 Dcyl, underwent aspheric LASIK treatment. In all cases pre- and postoperative BSCVA, manifest refraction, topography, pachymetry and corneal wave front analysis were performed. Corneal higher order aberrations were measured in 6, 7 and 8 mm diameter.
Results: 2 months after LASIK surgery, mean manifest refraction spherical equivalent (MRSE) for all eyes was -0.0186±0.3743. At the end of 2 months, UCVA â‰¥20/20 was achieved in 80%, â‰¥20/25 in 93% and >20/30 in 100% of eyes. No eye had lost two or more lines after surgery. Mean increase in total corneal higher order aberrations was 0.3446±0.2175 (P
