Abstract Details

Purpose:

To assess high-order aberrations (HOAs) induced after crosslinking in patients with keratoconus.

Setting:

Cornea and External consultation. Asociación para Evitar la Ceguera en México I.A.P.

Methods:

Prospective, longitudinal, interverntionist and descriptive study. Patients who had previous diagnosis of keratoconus with topography (Pentacam), measurement of aberrometries was performed (OPD3) precrosslinking and 90 days after. Inclusion criteria: Patients with maximum keratometry less than 60 diopter, spherical equivalent less than 10, signed informed consent. Exclusion criteria: Younger than 18 years old, pregnancy o lactation, , preexisting corneal diseases, systemic diseases, post refractive surgery ectasia.

Results:

81 eyes (55 patients) with keratoconus subjected to crosslinking. 42 (51.9%) were male. Average age: 25.5 ± 12.3 (11-78 años). Coma (90°): precrosslinking was -0.95 ± 1.26 and postcrosslinking was -0.73 ± 1.1 (p=0.003). Coma (0°): precrosslinking was -0.21 ± 1.05 and postcrosslinking was 0.16 ± 0.92 (p=0.78). RMS (Root Media Square): recrosslinking was 1.56 ± 1.09 and postcrosslinking was 1.37 ± 0.84 (p=0.0002).

Conclusions:

By comparing the measurements pre and postcrosslinking, we found a statistically significant reduction of the 90° coma and RMS postcrosslinking, while the 0° coma did not hace modifications
