Eye Exams in Calgary

What is an Eye Exam?

An eye exam is more than just an eye chart – it is a complete, comprehensive exam and detailed examination of your visual ability, vision and eye health. At Eyedeology, the following tests are performed in a comprehensive eye examination:

  1. Relevant History (ocular medical history, past medical history, family history)
    • changes in your vision and visual requirements
    • ocular history – incidences of eye conditions, prescriptions, eyewear, work with any other eye doctors, prior surgeries
    • past and current medical history and the medical history within your family, in order to determine your risk factors for certain eye health conditions and overall health conditions that may affect your eyes. 
    • List of medications and allergies
    • interest in contact lenses or refractive surgery
  2. Visual Acuity Examination
    We will examine your visual acuity by means of an eye chart to determine the your current visual acuity (the clearness of your vision).
  3. Ocular Motility Examination
    We will test how well your eyes and visual system function in terms of movement, reflexes and tracking in order to determine if there are any underlying problems with your ocular motility that may need remediation, or be symptomatic of other physiological or neurological conditions.
  4. Refraction
    A phoropter or similar device is used to determine the prescription for eyeglasses if one is needed. 
  5. Slit Lamp Examination of the Anterior and Posterior Segments of the Eye
    A slit lamp is used to facilitate an examination of the anterior segment of the human eye – including the conjunctiva, iris, natural crystalline lens and the cornea. A stereoscopic magnified view of the eye structures enable anatomical diagnoses to be made for a variety of eye conditions and diseases. Along with a non-contact fundus lens, a view of the fundus of the eye and other structures including the retina, optic disc, macula and fovea are assessed to help detect symptoms of conditions such as retinal detachment or glaucoma. 7. Advice or Instruction to the PatientPending your individual needs for care and follow-up, your optometrist will provide advice and/or referrals on a case by case basis. At this time, your optometrist will also advise you on how often to return for an eye exam.

Pre-testing Includes:

  1. Tonometry
    Tonometry is conducted to determine the intraocular pressure, the fluid pressure inside the eye. It is an important test in the evaluation of patients with glaucoma and to assess risk factors for glaucoma.
  2. Screening Visual Field examination 
    A screening visual field examination is used to detect and measure gross visual field loss in order to rule out such conditions of the eye alone, of the optic nerve or of the brain. 
  3. Fundus Photos of Posterior Segment
    Photos are taken of the eye and kept on file as a baseline. These are compared to images taken in subsequent years to determine if any change has occurred.

Additional Eye Examination

Dilated Fundus Eye Examination

Similar to the fundus examination mentioned above, but with the pupils dilated to enhance what your optometrist can see during the examination.

The Prescription

If the eye examination reveals that a vision problem exists and treatment with eye glasses or contact lenses is recommended, all of the information obtained from the examination is considered and a formula for eye wear is then determined. That formula becomes the prescription and cannot be determined unless all of the above elements of an examination have been performed and the results considered together. The portion of the eye examination that assesses the prescription alone in isolation has been described as a “refraction test” by the College of Opticians. A prescription for eye wear cannot be determined simply on the basis of the “refraction test” alone.

Optometrists Calgary

Optometrists are your primary care eye doctors. Doctors of optometry are trained to provide the best standards of comprehensive eye care, ranging from an assessment and review of overall eye health and visual function, to informing a prescription for eyeglasses or referring for secondary treatment by an ophthalmologist with surgery or drugs. Optometrists are your frontline care providers in eye health.

A regular eye exam is a key part of good vision health.
