Most ophthalmologists are trained and certified to perform a wide range of medical and surgical procedures. The procedures that an ophthalmologist regularly carries out depend on several factors, such as the type of practice and specialty in which they work.
Some of the most common everyday procedures that an ophthalmologist will perform include diagnosing and monitoring mild eye and vision conditions. They will also spend time prescribing and fitting glasses and contact lenses to correct vision problems. Subspecialist ophthalmologists tend to perform a smaller range of
procedures on a day-to-day basis, focusing instead on the treatment of one condition or a few related conditions.

Procedures that subspecialists commonly perform include:

• diagnosis and monitoring of moderate-to-severe eye conditions
• cataract surgery
• glaucoma surgery
• refractive surgery to correct vision
• cancer treatment
• reconstructive surgery to repair trauma or birth abnormalities, such as crossed eyes
• chronic or severe tear duct infections or blockages
• neoplasm ( tumor , cyst, or foreign object) removal
• monitoring or consulting on cases relating to other conditions, such as diabetic retinopathy or immune conditions
• injections around the eyes and face to alter facial structure function and appearance
• repairing torn or detached retinas
• corneal transplants
• LASIK/ Spectacle removal surgery
