摘要： An apparatus for measuring a cornea shape is capable of arbitrarily changing the diameter of ring illumination projected onto the cornea. The apparatus includes a light source for supplying a beam of light, a scanner system for scanning the beam of light from the light source and forming a light spot describing a circular locus on the surface of the cornea, and a device for observing therethrough the shape of the cornea on the basis of the locus described by the beam of light reflected by the cornea. The scanner system includes a reflecting mirror having a zonal reflecting surface disposed around the cornea, and a light deflector for directing the beam of light from the light source to the zonal reflecting surface.
