JARENO OCHOA, Madelyn et al. Tomographic results after the treatment of queratocono with corneal crosslinking. Rev Cubana Oftalmol [online]. 2020, vol.33, n.1 Epub 17-Jun-2020. ISSN 1561-3070.
Objectives:
Determine the tomographic modifications in patients with keratoconus treated with corneal crosslinking (CXL) in 8 years of evolution, in the Cuban Institute of Ophthalmology "Ramón Pando Ferrer".
Methods:
A descriptive, longitudinal and retrospective study was conducted of 58 eyes of 58 patients with progressive keratoconus, operated with corneal crosslinking in 2009. The statistical analysis was performed with the T-Test for paired data, with a significance of 95%.
Results:
The final mean of the SimK1, SimK2, KM and the topographic cylinder were 44,57 ± 3,08 D; 47,75 ± 3,96 D; 46,16 ± 3,28 D and 3,45 ± 2,35 D respectively. The final factor Q, Rmin, ISV, IHA and the KI index were -0,49 ± 0,34; 6,85 ± 0,73; 51,00 ± 20,09; 27,38 ± 12,77 and 1,05 ± 0,12 respectively. The final mean corneal volume, posterior elevation, central pachymetry, apex and finest point were 57,63 ± 2,45 mm3; 36,22 ± 27,42 µm; 458,97 ± 65,03 µm; 460,34 ± 64,90 µm and 454,79 ± 69,36 µm. The prolata cornea predominated with 62,1 %.
Conclusions:
The reduction in keratometry, topographic cylinder and ISV, IHA, and KI indexes with a tendency to stabilization showed a reduction in severe keratoconus.
