ABSTRACT:
An ophthalmological system and method is disclosed having an eye movement sensor. The eye movement sensor provides an output signal. A computer processor processes a signal and provides a signal output. The signal output is utilized to actuate movement of a prism assembly, typically including two or more prism elements located in front of the patient's eye and movable with respect to each other. Prisms are moved in an offsetting prismatic effect with respect to the eye movement to provide corrective vision from rapid involuntary eye movement such as nystagmus and strabismus.
