Description

The Marco Keratometer I is a one position instrument for objectively measuring corneal curvature. By simply rotating the Keratometer until a major axis is located, curvatures in both major and minor meridians can readily be measured. TheMarco Keratometer assures objective accuracy in such measurements as well as in the fitting of contact lenses. Manufactured with brass and stainless steel moving parts for durability, the Marco Keratometer incorporates such other features as precision objectives, achromatic prisms, and uniform diffuse illumination.
