Ophthalmology involves the treatment of the eye and vision disorders. An ophthalmologist is a physician who diagnoses and treats eye disorders and diseases, and sometimes performs eye surgery. Ophthalmology is more than just vision care. This specialist is trained to medically or surgically treat all ocular and vision problems, including disorders of the eyelids and visual pathways. The ophthalmologist also provides comprehensive vision exams and prescribes glasses and contact lenses.
