Epithelial hyperplasia usually occurs in parts of corneal despair. Performing transepithelial ablation, where the thickened epithelium shields the valleys from the laser energy, can make the most of the all-natural masking impact with the epithelium.
Direct bond breakage by a large-Strength photon is often a photochemical laser–materials interaction. The relative contribution of photochemical and thermal mechanisms into the UV ablation of organic and natural polymers is negligible. Within the shortest laser wavelengths, which include 193 nm, the significant photon Electrical power may end in a purely photochemical means of ablative photodecomposition.
