ophthalmology
Study of eyes
Ophthalmology is the branch of medicine concerned with the eye—its structure, diseases, and treatment.
An ophthalmologist is a medical doctor who diagnoses eye conditions, prescribes corrective lenses, and performs surgery: She went to ophthalmology for her cataract evaluation.
The field overlaps with but is distinct from optometry, which focuses on vision correction rather than surgical intervention.
