Optical Coherence Tomography (SD-OCT)
SD-OCT is the most advanced ocular imaging technology, it allows a highly detailed examination of the internal structures of the eye. It provides a highly detailed scan to create a three dimensional image of the inside of the eye. We can see below the surface of the retina and view microscopic layers beneath; as well as, image the structures of the front of the eye.
The SD-OCT is very helpful in the precise diagnosis and management of many diseases of the eye, including macular degeneration, glaucoma, retinal disease and other pathologies. Any change over time can be detected when comparing previous images to new images.
This imaging device also gives patients a view inside their eye’s structure and helps patients to better understand their eye’s condition.

With eye code physiological personalization, whether it is for Varilux or Essilor Single Vision lenses, the result is 5 times higher precision for Instant Vision, without effort. You can enjoy limitless vision with Varilux S series progressive lenses and Personalized single vision lenses. Visit www.varilux.ca
Humphrey Visual Field Perimeter (HFA)
Validated by decades of research and clinical experience, HFA is the accepted standard of care in glaucoma diagnosis and management. Glaucoma Progression Analysis software provides advanced, accurate progression analysis for better glaucoma management. This is useful for determining the likelihood of progression and identify high-risk patient. Also, it quantifies any central and peripheral vision deficit; both current and any change overtime. We continue to invest in the latest diagnostic equipment, with the purchase of our fourth HFA, a new 740i unit.
This instrument measures the exact shape of the front surface of your eye (the cornea). Using 1000 points your doctor will have a 3 dimensional map of the curvature of your corneal surface. This is used for contact lens fitting, refractive surgery, monitoring keratoconus and to diagnose and monitor any irregularity of the cornea.
Digital Fundus Photography
Retinal Camera technology is particularly important to detect and monitor ocular health at the retina. Often, we find things with this technology that might not be detected using more traditional examination methods. As well, it provides a permanent record of the condition of the retina so that small changes over time can be detected. It is particularly good at finding subtle changes at the retinal level for macular degeneration, diabetes, hypertension and glaucoma. A digital fundus camera is incorporated within our SD-OCT as a stand-alone diagnostic feature or as a comprehensive component of SD-OCT imaging.
The pachymeter is an instrument that uses ultrasound to measure the thickness of the cornea (the clear tissue in front of the coloured iris). It is useful in monitoring the progression of certain disorders that cause the cornea to become thickened (or filled with water), resulting in a loss of vision. Corneal thickness is also a risk factor for glaucoma and therefore this test may be performed by your optometrist. It can also be used to determine whether the cornea is strong enough or thick enough for procedures, such as laser refractive surgery.
