Ophthalmology is the branch of medicine that deals with the diagnosis and treatment of eye disorders and diseases. Ophthalmologists are medical doctors who specialize in the medical and surgical care of the eyes. They are trained to provide a wide range of eye care services, including performing eye exams, prescribing corrective lenses, diagnosing and treating eye conditions such as cataracts, glaucoma, and macular degeneration, and performing eye surgeries.
