An ophthalmologist is a doctor who specializes in eye and vision care. This professional is dedicated to the diagnosis, treatment and prevention of eye diseases and disorders, as well as the correction of vision problems. Ophthalmologists perform comprehensive eye exams to detect conditions such as glaucoma, cataracts, macular degeneration, and myopia, and offer treatments that may include medications, surgery, or eye lens correction. Additionally, ophthalmologists can perform eye surgeries such as cataract surgery, refractive surgery, and strabismus surgery. It is advisable to go to the ophthalmologist regularly for periodic eye checkups and to receive timely treatment in case of vision problems or eye diseases.
