- When should I see an Ophthalmologist like Dr. Entwistle?
- A visit to Dr. Entwistle is recommended for routine eye health check-ups, particularly if you have risk factors for eye diseases.

However, routine eye exams for adults of certain age groups without specific medical conditions, and procedures considered cosmetic (like elective refractive surgery or some eyelid procedures) are typically not covered. It's advisable to confirm coverage details with Dr. Entwistle's office or Ontario Health Insurance Plan (OHIP).
