Here in British Columbia, Canada, opticians have been doing stand alone refractions for the last several years. It is NOT "legal", and both the BC College of Physicians and Surgeons and the BC Board of Optometry have publicly denounced the practice. However, for reasons not understood, the provincial government has sided with the opticians, at least in spirit.
I have had several patients who were "sight tested" (the term used by opticians), that have had ocular pathology. I even had a monocular (prosthetic eye) patient with glaucoma in the other eye who came to see me because he didn't like his new glasses. Wow. Most recently I had a patient who was very unhappy with her glasses, and was told by the optician that was sight testing her that "this is as good as it gets". She had a 20/50 cataract in her right eye. I refered her for surgery. My question is what if it wasn't a cataract (a relatively easy fix), but a melonoma or glaucoma, or an RD??? The optician did not advise her to see a doctor...she came because of her own good judgemnt. Pathetic, I would say.
