Using advanced optometric equipment, Dr. Chow and Associates provide many services including:

  • Orthokeratology (myopia control, reduction of hyperopia, astigmatism & presbyopia).
  • Contact lens fitting (regular & specialty contact lenses including keratoconus and corneal rehab post Lasik surgery).
  • Ocular nutrition: to prevent and treat AMD, cataract, glaucoma, dry eye syndrome, and diabetic retinopathy.
  • Laser Refractive Pre- Post-Op.

Corneal Topography

The Medmont E300 Corneal Topographer is the gold standard for specialty contact lens fitting. It also allows for diagnosis of corneal disease such as keratoconus as well as evaluation of dry eye syndrome.

Fundus camera optometrist Toronto

Digital Imaging Fundus Camera

Creates a complete picture of the fundus for detection of any anomalies such as diabetic retinopathy, macular degeneration and optic nerve atrophy.

Optical Coherence Tomography (OCT)

The latest in diagnostic technology, the OCT is essentially an “optical ultrasound”,and provides a rapid, non-invasive view of the structures of the eye at a near microscopic level.  This is proved to be an invaluable tool in the diagnosis of retinal disease, and the early detection of glaucoma. The OCT is also used for specialty contact lens fitting and evaluation of glaucoma.

Ocular Response Analyzer

The Ocular Response Analyzer (ORA) is the only advanced tonometer that factors in corneal biomechanics. This allow for the most accurate measurement of eye pressure as well as provide superior prediction on glaucoma progression, especially in those at risk for normal tension glaucoma.

Lumenis M22 OPT IPL dry eye Toronto

Lumenis M22 OPT IPL

The Lumenis M22 OPTTM Intensive Pulse Light platform is used to treat dry eye. The M22 is Lumenis’ newest and most advanced IPL platform, CE approved and FDA cleared for over 30 different skin indications.

Color Vision Assessment Markham Ontario

Color Vision Assessment

We utilize the D-15 Farnsworth Dichotomous Color Blindness test for color vision assessment. This is currently the standard requirement for applicants to the Royal Canadian Mounted Police as well as the local police departments.


Checking macular pigment density to prevent age related macular degeneration (AMD).

Corneal Pachometry

Measures corneal thickness to detect glaucoma.

Non-contact Automated Tonometer

Measures the intra-ocular pressure for the detection of glaucoma.

Automated Visual Field Testing

The Humphrey Visual Field Analyzer is the industry standard test used to assess the sensitivity of the eye as well as the extent of the peripheral vision.  It is approved for use for the Ontario Department of Motor Vehicles vision testing.  In addition, visual field tests are useful in the detection of retinal disease, and in the detection of diseases affecting the visual pathways of the brain, including stroke or brain tumors.
