About Referrals

This section contains clinical and other resource information for optometrists and other health care practitioners (HCPs) who refer patients to our clinic. In order to accept a referred patient, practitioners must fax a referral letter to us requesting an appointment including doctor and patient contact information, patient clinical information and reasons for the referral.

1) Low Vision Assessment Information for Referring Practitioners
 

The Vision Institute of Canada continues its long tradition of serving the needs of the growing low vision population. On a first visit to the Low Vision Service, the patient undergoes an hour-long assessment with an emphasis on exploring functional goals through:

1) a comprehensive case history,
2) precise visual acuity measurements,
3) contrast sensitivity testing,
4) relevant visual field assessment,
5) careful refractive analysis, and
6) evaluation of additional optical or non-optical requirements.

When a need for auxiliary devices is established, the patient is guided through a collaborative selection process, in which the practitioner and patient contribute equally. Low vision aids take many forms. Commonly prescribed devices include high additions, spectacle microscopes, hand or stand magnifiers, telescopes, filters, and closed circuit televisions (CCTV). When low vision aids are prescribed, eligible Ontario patients are able to make use of the Vision Institute's status as an Assistive Devices Program (ADP) authorizer/vendor. This program provides provincial funding to subsidize the cost of optical devices. In addition, the Vision Institute of Canada is one of ten Ontario Regional Assessment Centres, which authorize ADP funding for CCTVs. When necessary, the Vision Institute arranges referral to allied agencies, for example, to "high technology" clinics for computer adaptation, or the CNIB. Reassessments are arranged as needed. A report of each visit is sent to the referring agency or health care practitioner.

The ideal candidate for the Low Vision Service is a patient whose best-corrected vision fails to meet his or her needs, who has a realistic acceptance of this challenge, and who is willing to consider solutions beyond the conventional.

An appointment can be made by faxing a referral letter to the Institute indicating the patient's name, age and contact information, diagnosis, present refraction, best-corrected visual acuity and any other relevant information.

2) Topography Testing Information for Referring Practitioners

Corneal topography provides detailed mapping of the surface curvature of the cornea similar to a contour map of a land surface. The cornea is responsible for 70% of the eye's refractive power. The shape of the cornea determines the visual and refractive ability of an otherwise healthy eye. 

The corneal topographer uses a computerized lighted bowl that contains a pattern of concentric rings. The patient is seated in front of the lighted bowl, which then allows a series of data points to be generated on a Placido's disc, and is projected on to the cornea. Computer software digitizes these data points to produce a printout of the corneal shape, using different colours to identify different elevations. The topographer provides quantitative and qualitative evaluations of the corneal curvature.

Corneal topography gives a detailed description of the shape and power of the cornea. The corneal topographer aids the practitioner in the diagnosis of corneal disorders, evaluating disease progression, fitting specialty contact lenses and planning for refractive surgery.

Corneal topography is recommended in the diagnosis and management of various corneal abnormalities and diseases such as:

1) Keratoconus
2) Post-LASIK ectasia
3) Corneal scars and opacities
4) Corneal dystrophies such as anterior basement membrane dystrophy and Fuch's endothelial dystrophy
5) Corneal transplants

The Vision Institute accepts referrals for corneal topography. An appointment can be made by faxing a referral letter to the Institute indicating the patient's name, age and contact information, present refraction, and other relevant findings from the most recent eye examination.

3) Specialty Contact Lens Fitting Information for Referring Practitioners
 

The Vision Institute of Canada provides specialty and medical contact lens services to patients. The Vision Institute is a great resource and referral center for practitioners to manage specialty or "hard to fit" contact lens patients.

A contact lens evaluation and fitting includes:

1) a complete refractive assessment
2) an examination of the ocular surface
3) a dry eye evaluation
4) corneal topography (if indicated)
5) an initial contact lens fitting procedure
6) teaching of insertion and removal (if indicated)
7) three months of follow-up care.

The Vision Institute fits and manages a large number of keratoconus patients that have been referred to us from other practitioners. Besides keratoconus, we also provides specialty fits for post-penetrating keratoplasty, aphakia, high astigmatism, radial keratotomy and post-LASIK ectasia.

Our contact lens service includes fitting lenses to children with anisometropia, high astigmatism, and high hyperopia. We also provided multifocal contact lens fittings for the increasing presbyopic population.

Other specialty contact lens services include prosthetic or cosmetic lenses for aniridia, congenital ocular defects and ocular trauma.

A contact lens evaluation and fitting appointment can be made by faxing a referral letter to the Institute indicating the patient's name, age and contact information, present refraction, and other relevant findings from the most recent eye examination.

Testimonials

Reviews From Our Satisfied Patients

  • "We use Anderson Optometry for all of our family’s vision needs. Recently, we had to have our youngest fitted for new glasses and he made the experience fun for her and informative for us. We know Dr. Anderson will always take good care of our family’s eye care and that’s why we wouldn’t go to anywhere else."
    The Harrison Family
  • "Dr. Anderson and his staff are so patient and friendly. Dr. Anderson prescribed me glasses and I had the toughest time picking out frames. They didn’t rush, but instead made helpful suggestions and now I have an awesome pair of frames, not to mention the fact that I can see ten times better than before. You guys are the best!"
