The goal of this clinical trial is to document corneal ectasia stability in patients with keratoconus diagnosis treated with personalized cross linking energy. The main questions it aims to answer are: * Is it effective while using personalized (reduced) energy? * Is it safe for corneas thinner than 400 microns? Participants will be treated with personalized energy corneal cross linking and posteriorly, will attend subsequent follow-up consults

RECRUITINGKeratometry stability
Stability documented by changes in keratometries (measured in diopters) obtained with corneal tomography, as well as uncorrected visual acuity observed in follow up consults
Time frame: Baseline and 6 months
Pachymetry stability
Stability documented by changes in pachymetry (measured in microns) obtained with corneal tomography
Time frame: Baseline and 6 months
Uncorrected visual acuity stability
Stability documented by changes in uncorrected visual acuity (measured in logarithm of the minimum angle of resolution) obtained on physical examiantion
Time frame: Baseline, 72 hours, 1 week, 3 months and 6 months
Corneal endothelium safety
Corneal endothelial cell count obtained by specular microscopy
Time frame: Baseline, 72 hours, 1 week, 3 months and 6 months
