摘要
Ne analyse the role of corneal asphericity in visual function after refractive surgery. For this, the standard ablation algorithm has been modified considering two corneal-asphericity terms. We have calculated the MTF (modulation transfer function) for different groups of average myopes taking spherical aberration into account and have verified that the MTF could be improved when asphericity is considered. These results may be useful in developing new algorithms for improving the retinal-image quality after refractive surgery.
