An ophthalmologist is a medical doctor who specializes in eye and vision care.

They can:

• Perform eye examinations
• Diagnose and treat eye diseases and injuries
• Prescribe glasses, contact lenses, and medicines
• Perform eye surgery, such as cataract surgery
• Treat conditions such as glaucoma, cataracts, and retinal problems

Unlike an optometrist, an ophthalmologist is a medical doctor trained to perform surgery and treat complex eye conditions.
