ABSTRACT

Objective: Determine the topoaberrometric characteristics of keratoconus.
Methods: A cross-sectional observational descriptive study was conducted of 101 corneal topograms of patients diagnosed with keratoconus obtained with the corneal topograph Magellan Plug and Play (n= 101 eyes) at Ramón Pando Ferrer Cuban Institute of Ophthalmology in the period 2016-2017.
Results: The age groups best represented in the sample were 20-29 and 30-39 years, with a similar proportion of male and female patients. A predominance was found of patients with clinical keratoconus by the severity index and with pathological classification by the prediction index, with an ascending correlation between the two indices. Central cone location was the most frequent in the sample, with a prevalence of the highest levels of the aforementioned indices. A high frequency was found of coma higher-order aberration, according to root mean square and maximum spherical aberration values.
Conclusions: The age group best represented in the study sample is 20-39 years, with a similar proportion of male and female patients. A predominance is found of patients with clinical keratoconus by the severity index and with pathological classification by the prediction index, with an ascending correlation between the two indices.
