To describe two patients with moderate keratoconus and a corneal thickness exceeding 600 μm at the thinnest point.
Case report.
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.
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.
描述两例角膜最薄点厚度超过 600μm 的中度圆锥角膜患者。
病例报告。
在第一例中，右眼的最陡角膜屈光力为 51.50 屈光度（D），左眼为 53.4D，最薄点的厚度分别为 658μm 和 625μm。在第二例中，右眼的最陡角膜屈光力为 46.70D，左眼为 49.60D，最薄点的厚度分别为 618μm 和 608μm。
尽管角膜非常厚，圆锥角膜仍可能发展，这进一步证实了生物力学变化可能是该病理发展和进展的一个重要因素。
