[Evaluation of eye total aberration in patients with keratoconus].

PURPOSE: Evaluation of total eye aberration in patients with I, II, III degree of keratoconus according to Amsler scale, and results compared with normal group patients, having only refractive error.

MATERIAL AND METHOD: The analyzed group of patients consisted of 43 patients (55 eyes), who underwent examinations: visual acuity, subjective and objective refractive error, cornea keratometric power, pupil diameter and total eye aberration performed by System WASCA (Asclepion-Meditec). Our patients were divided in to two groups: group I--16 patients with keratoconus (25 eyes), group II--27 control patients (30 eyes).

RESULTS

Comparison of all analyzed parameters in both groups were statistical significant. In eyes with keratoconus coma aberrations excel spherical aberrations.
