What
is an Optometrist?
An
optometrist is a doctor of optometry who is trained to perform eye
examinations for all ages. Optometrists are primary health care
professional who examine, diagnose, treat and help prevent diseases
and disorders of the visual system, the eyes and related structures.
An
optometrist is required to do a minimum of 3 years in a bachelor
of science program at university, followed by 4 years of professional
school at a School of Optometry. Optometrists are licenced by
the Board of Examiners in Optometry in British Columbia, the professions
provincial regulatory body. Every BC optometrist is also a member
of the British Columbia Association of Optometrists.
What
is an Ophthalmologist?
Ophthalmologists
are physicians who, after graduating from medical school, undertake
several years of post-graduate training in the diagnosis and treatment
of diseases of the eye. Eye surgery is preformed by ophthalmologists.
Patients require a referral from their optometrist or family physician
to visit an ophthalmologist.
What
is an Optician?
Opticians
supply, prepare and dispense optical appliances based on prescriptions
prepared by optometrists and ophthalmologists. Opticians in BC
complete a 6 month to one year training program after which they
take a national examination that enables them to dispense eyeglasses.
Additional training is required to dispense contact lenses.
What
is a sight test?
A
sight test, more accurately called a refraction, determines a
lens prescription by relying on a combination of computerized
tests using automated equipment.
The
comprehensiveness and accuracy of these automated sight tests
is limited. Eye muscle co-ordination is completely ignored, and
the test results can be influenced by eye fixation and alignment,
pupil size, corneal or lens irregularities, and something called
instrument myopia. This last problem is caused by the eyes
tendency to have its focus altered by the device being looked
through. This can lead to an inaccurate measurement of refraction.
These
sight tests will completely overlook many serious problems and
diseases that do not blur a persons vision at all or
until the disease is more advanced. Some of these include; glaucoma,
Type 2 diabetes, brain tumours, cancer of the eye, high blood
pressure and retinal detachements. Early detection of these conditions
is important to be able to protect not only the health of the
eyes and the clarity of vision, but also the patients overall
health and maybe even their life. Having a refraction (a
sight test) done without an eye health examination presents serious
risk.
Only
ophthalmologists and optometrists are allowed to perform refractions
and issue prescriptions. The regulatory bodies of medicine and
optometry will not allow their members to provide refractions
without also doing a complete eye health examination. In other
words, ophthalmologists and optometrists are not allowed to
sight test as it is considered to be dangerous for the public.
Some
opticians are currently conduction sight tests. Originally they
started by faxing the computer results to a doctor who would sign
a prescription and fax it back without ever having examined the
patients eyes. The College of Physicians and Surgeons of
British Columbia stopped that practice with the following declaration;
In signing a prescription based on a refraction, a physician
is practicing medicine and acknowledging a physician-patient
relationship with all of the ethical and legal encumbrances
of that.
Ocular health can only be certified by a complete ocular examination.
The signing of a prescription for visual correction, based on
autorefraction, without taking a history from the patient and
without conducting an ocular examination of that patient to
ensure that no concurrent ocular pathology exists, is unacceptable
medical practice.
On
March 30, 2004 the BC government issued a media release announcing
its plan to allow opticians to perform sight testing without the
supervision of an optometrist or an ophthalmologist. The government
phrased the release as More Choices for Eye Health Care.
If
this regulation proposed by Minister Colin Hansen is allowed,
then BC will have the lowest standard of eye care in North America.
No other jurisdiction in North American allows sight testing by
anyone, ophthalmologist, optometrist or optician as it is considered
not safe.
The
Board of Examiners in Optometry, the BC Association of Optometrists,
the College of Physician and Surgeon and the BC Medical Association
have all criticized the proposed sight testing regulation as being
a serious health risk. So far the government has been unwilling
to listen to the advice of the medical community.
If
you would like to help fight the proposed sight testing legislation,
please call or write to your MLA to voice your opinion. All calls
and letters from constituents are tallied and it does make a difference.
