OCULAR TOPOLOGY SYSTEM

Topological information of the cornea and anterior chamber of an eye is optically developed by projecting toward said eye a target image sharply focused in a movable flat plane. As the plane is moved through the eye, the reflection of the target is in focus first at the center and then at increasingly radially outward locations. The reflection is detected and clipped to delete all image portions which are out of focus. As the image plane is moved through the eye, the clipped reflection traces the topology of the eye. This information can be fed into a computer and used to compute appropriate topological displays. Such computations can readily be made insensitive to any eye movement during the measuring process.
