Kalkan Akcay E, et al. - The alterations in the ocular surface and tear film parameters 3 months after accelerated corneal collagen cross-linking (A-CXL) in progressive keratoconus (KC) patients was explored in this study. Only metaplastic changes and a reduction in the density of the goblet cells were seen in conjunctival IC, which is probably due to the toxicity of ultraviolet-A 3 months after A-CXL. However, these results do not lead to deterioration in TBUT. In this study, A-CXL has no adverse effect on ocular surface and tear function, which are essential for visual quality.
