Moderate keratoconus with thick corneas.

PURPOSE

To describe two patients with moderate keratoconus and a corneal thickness exceeding 600 μm at the thinnest point.

METHODS

Case report.

RESULTS

In the first case, the steepest keratometric power was 51.50 diopters (D) in the right eye and 53.4 in the left eye and the thickness at the thinnest point was 658 and 625 μm, respectively. In the second case, the steepest keratometric power was 46.70 D in the right eye and 49.60 D in the left eye and the thickness at the thinnest point was 618 and 608 μm, respectively.

CONCLUSIONS

Keratoconus may develop despite a very thick cornea, reinforcing the idea that biomechanical changes can signify an important factor in the development and progression of this pathology.
