The Key Differences at a Glance

How They Work Together
In Canada's eye care system, optometrists and ophthalmologists work as a team:
1. **You see an optometrist** for your annual eye exam
2. **The optometrist diagnoses a condition** that requires specialist care (e.g., advanced glaucoma, cataract)
3. **The optometrist refers you to an ophthalmologist** for surgery or specialist management
4. **The ophthalmologist performs the procedure** and may refer you back to the optometrist for follow-up care
This collaborative model ensures you get the right level of care at each stage.
