Method and apparatus for detecting and modifying peripheral curves and junction ridges in contact lenses

摘要

Apparatus and method for detecting and modifying discontinuities on the ocular surface of a patient's contact lens by alternately observing the reflected image of one or more parallel opaque bands superimposed on an illuminated translucent background and modifying the ocular surface until the detected malformations are removed and the ocular surface conforms to the conjugate profile of the patient's corneal surface.
