This instrument allows an office assistant to obtain accurate measurements on the majority of patients.
Research continues on further automation of such instruments.
Development of the Potential Acuity Meter, a device to measure the potential visual acuity of cataractous eyes, thus helping to predict whether surgery will be of benefit, particularly when other disease is present as well. Other methods of measuring potential visual acuity are currently under development. Development of optical systems for remote examination of strabismic patients and measurement of visual function in infants. Large concave mirrors image the patient into a remote location where various tests can be performed, avoiding distracting apparatus before the patient's eyes. Tests are presented remotely on video displays under computer control.
