title: [A method for determining the refraction of the central corneal area].
abstract: The technique of ophthalmometry at various sites of the central corneal area, using several ophthalmometric systems, is described. These measurements have revealed that only the corneal center is characterized by a spherical shape with a diameter of about 4 mm.
