ophthalmic medical technician, an allied health professional who assists ophthalmologists by collecting data and administering treatment ordered by the ophthalmologist. These specialists are qualified to take medical histories; administer diagnostic tests; make anatomical and functional ocular measurements; test ocular functions, including visual acuity, visual fields, and sensorimotor functions; administer topical ophthalmic medications; and instruct the patient in home care and the use of contact lenses. Ophthalmic medical technologists perform all duties performed by technicians but are expected to do so at a higher level of expertise.
