JARENO OCHOA, Madelyn et al. Refractive modifications after treatment of keratoconus with corneal crosslinking in eight years of evolution. Rev Cubana Oftalmol [online]. 2020, vol.33, n.1 Epub 17-Jun-2020. ISSN 1561-3070.
Objectives:
Determine the refractive modifications in patients with keratoconus treated with corneal crosslinking in eight years of evolution.
Methods:
A descriptive, longitudinal and retrospective study was performed in 58 eyes of 58 patients with progressive keratoconus, operated with corneal crosslinking in 2009. Statistical analysis was performed with the T-test for paired data, with 95% significance.
Results:
Female sex predominated with 55.2%. The mean age was 27.6 ± 6.7 years and stage II according to Amsler-Krumeich, with 53.4%. The final mean of uncorrected visual acuity, best corrected, sphere, cylinder, and spherical equivalent was 0.34 ± 0.25; 0.63 ± 0.19; 6.16 ± 3.32 diopters; -2.81 ± 2.00 dioptres and -7.41 ± 3.69 dioptres respectively.
Conclusions:
In the treatment of progressive keratoconus with corneal crosslinking, there is a significant improvement in uncorrected visual acuity and better corrected visual acuity, as well as reduction of the sphere, cylinder and spherical equivalent.
