Comparison between three protocols of corneal collagen crosslinking in adults with progressive keratoconus: Standard versus accelerated CXL for keratoconus.

The standard CXL showed better results for keratometry and astigmatism in comparison with the accelerated. Therefore, the wide use of the accelerated CXL should be considered and reviewed for longer follow-up time and larger sample size in focus on the visual acuity parameters.
