Results highlights the use of the safety protocols which include riboflavin application for half an hour before exposure to ultraviolet radiations, removal of epithelium, ultraviolet irradiance of 370 nm wavelength, and 400 μm minimum corneal thickness. The adequate technique and safety procedure must be followed as it can lead to damage of retina, lens, and endothelium. |
