The levels of training and expertise, and the core competencies, are different for each type of eye care provider.
An Optometrist, or Doctor of Optometry, has completed a Bachelor of Science degree or higher, followed by a four year Doctor of Optometry degree from an accredited university’s school of optometry. Optometrists provide the following: an optometric eye exam to examine, assess, measure and diagnose disorders and diseases within the human eye and visual system. They can detect disorders of the eye such as glaucoma, cataracts and macular degeneration and recognize and co-manage related systemic conditions, such as diabetes, high blood pressure and brain tumors. Most can prescribe medications (this varies by province – so ask your Doctor of Optometry for details), perform removal of foreign bodies from the eye, and provide referrals to secondary specialists, such as Ophthalmologists, for treatment of systemic disease or eye surgery when necessary. In cooperation with an Ophthalmologist, they co-manage ocular diseases. Finally, they can co-manage pre- and post-operative care for laser vision correction.
Ophthalmologists are surgeons and specialists in eye disease. They have completed a Bachelor degree and four years of medical school at an accredited university, as well as a residency in medical and surgical care of the eyes in an accredited university hospital. They are secondary-level healthcare providers and patients usually require a referral from their Doctor of Optometry to obtain an appointment for medical or surgical treatment such as cataract surgery.
Opticians are the third member of the eye care team. They are trained through a college program to fabricate and fit vision aids, such as glasses, based on the prescription of a Doctor of Optometry or physician. Opticians are licensed to provide spectacles, and they may also dispense contact lenses and other optical aids. They do not assess, diagnose or treat eye conditions.
