Who is an ophthalmologist?

An ophthalmologist is a medical doctor (MD or DO) who specialises in eye and vision care. They are trained not only to diagnose and treat all eye conditions but also to perform surgeries.

What Does an Ophthalmologist Do?

  1. Perform comprehensive eye exams.
  2. Diagnose and treat eye diseases like glaucoma, cataracts, diabetic retinopathy, and macular degeneration.
  3. Conduct eye surgeries, such as cataract removal, LASIK, corneal transplants, and retinal surgeries.
  4. Prescribe medications for infections, allergies, or chronic eye diseases.
  5. Provide follow-up care after surgical or medical treatment.

Example:

If someone has blurred vision due to a cataract, only an ophthalmologist can perform the surgery to replace the cloudy lens with an artificial one.

Who is an optometrist?

An optometrist is a healthcare professional who provides primary vision care. They are not medical doctors but hold a Doctor of Optometry (OD) degree.

What Does an Optometrist Do?

  1. Perform eye and vision tests.
  2. Prescribe eyeglasses and contact lenses.
  3. Detect vision problems such as nearsightedness, farsightedness, or astigmatism.
  4. Screen for eye conditions like glaucoma, cataracts, or retinal disorders.
  5. Provide vision therapy and low-vision rehabilitation.
  6. Refer patients to ophthalmologists for surgical or complex treatments.

Example:

If you are struggling to read text on your phone or need new glasses, an optometrist is the right professional to visit first.

Ophthalmologist vs. Optometrist - Key Differences

When Should You Visit an Optometrist? 
  1. If you need regular eye checkups.
  2. When your vision feels blurry and you suspect you need glasses or contact lenses.
  3. For contact lens fitting and management.
  4. If you have minor eye issues like dryness, redness, or strain.
  5. For monitoring existing eye conditions before referral.

When Should You Visit an Ophthalmologist?
  1. If you are diagnosed with a serious eye disease like glaucoma or diabetic retinopathy.
  2. When you need eye surgery (cataract, LASIK, corneal transplant).
  3. In case of eye injuries or sudden vision loss.
  4. If you have chronic eye pain or severe infections.
  5. For advanced treatment that cannot be managed by an optometrist.

How Ophthalmologists and Optometrists Work Together

Even though their roles differ, both work hand in hand to provide the best eye care.
  1. Optometrists are usually the first point of contact for patients. They detect vision problems and basic eye conditions.
  2. If a condition requires surgery or advanced treatment, the optometrist refers the patient to an ophthalmologist.
  3. After surgery, the ophthalmologist may send the patient back to the optometrist for follow-up care and vision management.

This teamwork ensures that patients receive complete care, from diagnosis to treatment to rehabilitation.

Common Eye Problems and Whom to Consult
  1. Refractive Errors (Myopia, Hyperopia, Astigmatism, Presbyopia) → Optometrist
  2. Cataract → Ophthalmologist (for surgery)
  3. Glaucoma → Ophthalmologist (treatment and monitoring)
  4. Eye Allergies or Conjunctivitis → Optometrist or Ophthalmologist (depending on severity) 
  5. Diabetic Retinopathy → Ophthalmologist
  6. Routine Eye Check-up → Optometrist
  7. Sudden Loss of Vision → Ophthalmologist (emergency)

Importance of Regular Eye Exams

Many eye diseases are silent in the beginning, showing no symptoms until they have progressed. Regular checkups help in early detection, which can save vision.
  1. Adults should have an eye exam every 1–2 years.
  2. People with diabetes or high blood pressure should visit annually.
  3. Children should have routine exams to detect vision issues early.
  4. Seniors (60+) need more frequent monitoring for cataracts, glaucoma, or age-related macular degeneration.

Tips to Maintain Good Eye Health
  1. Eat a diet rich in vitamins A, C, and E and omega-3 fatty acids.
  2. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
  3. Wear sunglasses to protect from harmful UV rays.
  4. Avoid smoking, as it increases the risk of cataracts and macular degeneration.
  5. Maintain good blood sugar and blood pressure levels.
  6. Use protective eyewear when working with chemicals or sharp tools.
