Abstract
An ophthalmometer system is provided which includes a white light source for illuminating a cornea during surgery, along with an infrared light generator for imaging concentric rings onto the cornea and a detection system for receiving the reflected infrared rings and providing them to a display to enable the surgeon to see the corneal topology as indicated by the nonconcentricity or concentricity of the reflected rings. The surgeon can thus view the cornea topology concurrently with surgical operations on the eye.
