Being at the forefront of technology, Eyes on Sheppard is one of the first centers in Canada to utilize these diagnostic imaging devices.
Corneal Topography – Digital Mapping
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye’s refractive power, the shape of the cornea is critical in determining the quality and clarity of vision.
We now have TWO top-of-the-line corneal topographers; the Medmont and the Oculus Keratograph 5M use three-dimensional digital mapping to assist in the diagnosis and treatment of a number of diseases including keratoconus or pellucid marginal degeneration. In addition, this new technology is important in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses for astigmatism or orthokeratology. It uses a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.
Dry Eye Analysis
The latest innovation of the corneal topographer is its ability to look at Dry Eye Syndrome. Dry Eye disease is one of the most common conditions presenting to our office. Symptoms include burning, grittiness, light sensitivity, excessive tearing, and/or fluctuating vision. The Keratograph 5M not only can map the surface of the eye but can also accurately measure the quality and quantity of tears on the surface of the cornea. The integrity of the oil secreting glands of the lids are also imaged. This remarkable technology can help diagnose the various types of dry eye conditions and then personalized treatment plans can be tailored to maximize outcomes.
Patient Information, Eyeglass Guide and Cataract lens options
At Eyes on Sheppard, we understand the value of time and education. Being at the forefront of technology, we understand that the Web has lots to navigate through. We have developed an online portal for the latest patient-friendly eye care education through:
We have also partnered with EyeglassGuide.com, to assist you in choosing appropriate frames and lenses. For information on the latest cataract surgery and intra-ocular lens options: www.myvisionoptions.ca

Digital Retinal Imaging (OPTOMAP) & OCT Scans
We use cutting-edge digital imaging technology to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Your retinal images will be stored electronically in your file. This gives the Doctor of Optometry a permanent record of the condition and state of your retina and can be compared year after year.
This is very important in assisting your Optometrist to detect and measure any changes to your retina each time you get your eyes examined, as many eye conditions, such as glaucoma, diabetic retinopathy and macular degeneration are diagnosed by detecting changes over time.
Digital Retinal Imaging – OPTOMAP
Eyes On Sheppard continues to bring the most advanced technology to our patients. Since 2003, the Optomap technology has been part of our comprehensive eye exam. The Daytona Optomap is the next generation of ultra-wide retinal imaging systems that non-invasively captures an instantaneous digital scan of the retina, revealing important information about the health of the back of the eye, the retina. It is critical to confirm the health of the retina, optic nerve and other retinal structures and is used as a baseline to track any changes in your eyes.
Optical Coherence Tomography (OCT)
An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.
A scanning laser is used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to a CT scan of the brain. It works using light without harmful radiation, and is essential for early diagnosis of glaucoma, macular degeneration and diabetic retinal disease to see areas behind the eye that can not be seen with the naked eye.
With an OCT scan, the underlying structures of the retina can be visualized. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.
An OCT scan is a non-invasive, painless test. It is performed in about 10 minutes right in our office.
Visual Field Testing
A visual field test measures the range of your peripheral or “side” vision to assess whether you have any blind spots (scotomas), peripheral vision loss or visual field abnormalities. It is a straightforward and painless test that does not involve eye drops but does involve the patient’s ability to understand and follow instructions.
A visual field is performed one eye at a time. You start by placing your chin on the chin rest with instruction to keep your gaze fixed on a central object while stimuli like lights or vibrations are flashed in your periphery. When you use your peripheral vision and see a light or vibration, you are to press a button. The stimuli vary in brightness and intensity throughout the test to test the threshold of what you see and will be compared to other people in your age group. Each eye is tested separately and the entire test can take from 2-10minutes. These instruments can create a computerized map of your visual field to screen for diseases or deficiencies like glaucoma, tumours or side effects from medications.
BlephEx- The first and only doctor treatment for blepharitis
Eyes on Sheppard is one of the first practices in North America to offer a new in-office treatment for blepharitis. Blepharitis is an inflammation of the eyelid which commonly occurs when tiny oil glands located near the base of the eyelashes become clogged. This leads to irritated, itchy and red eyes. Blepharitis is often a chronic condition that is difficult to treat. Blepharitis can be uncomfortable and may be unsightly. But it usually doesn’t cause permanent damage to your eyesight, and it’s not contagious.
BlephEx is a new procedure to treat blepharitis by reducing the crusts and bacterial debris, the main causes of inflammatory lid disease, and improves the overall health of the eyelids. If you suffer from symptoms of itchy or scratchy eyes, tearing, crusting around lids, redness, and dry eyes, you may be a candidate for the BlephEx treatment.

The OPD-Scan III analyzes a patient’s unique ‘optical fingerprint’ to provide the most precise spectacle and contact lens prescription. The OPD can detect even the most obscure vision errors based on the way light travels through the eye to provide high definition vision.
The data generated by the OPD can also be used to identify patients that require different prescriptions for day and night vision. As part of our mission to provide our patients with the latest in eye care technology, we are now incorporating the OPD III into our routine eye exams.
