Purpose: Our experiment evaluated the biomechanical effects of riboflavin and ultraviolet A illumination, in terms of covalent bonding, permeability, and indentation rupture force, on excised cattle conjunctiva.
Materials And Methods: Cattle conjunctiva was extracted and divided into the treatment group, which was soaked in riboflavin, followed by ultraviolet light illumination, and the control group. Samples were subsequently analysed on a Fourier transform infrared spectrum test to identify the presence of amide bonds, a permeability test to assess the diffusion of methylene blue across conjunctiva, and an indentation rupture force test.
