Background and Objectives: The method of riboflavin/UV collagen cross-linking is widely used to strengthen the corneal stroma in the treatment of keratoconus and is of considerable interest as a possible method to improve the biomechanical property of the sclera in the treatment of myopia. Regarding the application of this method to the sclera, one of the important problems is the rapid decrease in the intensity of UV radiation due to scattering as it propagates into the tissue.
