Measuring Wait Times for Eye Surgeries


Priority levels and target times for eye surgeries in Ontario are set by surgeons, specialists and health care administrators across the province, based on clinical evidence, to guide treatment decisions and to improve patient access and outcomes.

Wait times in Ontario are measured and reported for cataract, corneal transplant, glaucoma, and vitrectomy (retina) surgeries. Those wait times are for two periods. (Data excludes patients who did not have the surgery after their first appointment with a surgeon.)

Time to patient's first eye specialist appointment: How long patients waited from an eye specialist or surgeon or central intake office receiving the referral from the patient's doctor, to the patient's first eye specialist appointment.
