Abstract
 
Purpose
 

To analyze the topographical, pachymetric, keratometric and refractive changes induced by Crosslinking in eyes with keratoconus, 3 year follow-up at Hospital de la Luz in Mexico City.

 
Methods
 

A descriptive, retrospective, in 21 patients (23 eyes) with progressive keratoconus who underwent Crosslinking during September 2011 and 2014. Data were collected preoperatively, a month, three months, six months and one year study. The variables studied were age, gender, visual acuity without correction, spherical equivalent, topographic keratometry and corneal thickness.

 
Results
 

Male predominated (66%), we obtain an average of 21 years old and an increased stage two of keratoconus (Amsler-Krumeich). The best corrected visual acuity modifies from 0.29 ± 0.30 preoperatively to 0.17 ± 0.1 after the first month of surgery. The spherical equivalent from -8.25 ± 6.28D decreases to -1.48 ± 1.94 diopters to the sixth postoperative month. The maximum preoperative keratometry topographic from 56.38 ± 26.38 to 40.65 D at the third month. Preoperative central optical pachymetry from 430.81 ± 59.30 microns to 389.33 ± 57.03 micron after a year and the thinnest pachymetry from 408.81 ± 61.51 microns to 357.16 ± 74.32 microns after the year control.

 
Conclusions
 

Significant keratometric, pachymetric, topographic and refractive changes are shown to arrest the progression of keratoconus in patients undergoing Crosslinking in a medium term.
