Excerpt
Excimer laser surgery has become the dominant procedure to correct refractive errors worldwide. Numerous technological developments such as flying-spot lasers, eye trackers, and modern microkeratomes have improved the clinical outcome [
22]. The advent of wavefront measurement technology enabled the quantification of ocular aberrations [
29]. Experience with adaptive optics from astronomy led to the concept of correcting ocular higher-order aberrations (HOA) by excimer laser surgery. Wavefront-guided ablation should improve the image quality of the eye and therefore improve visual acuity, as observed with adaptive optics [
30]. Reports of single cases treated with wavefront-based algorithms reaching a visual acuity of 20/10 and better raised the hope to further improve the visual outcome of refractive corneal laser surgery [
33]. …
