Contact Lens Exams

Dr. Bart McRoberts, Dr. Clark Bowden, Dr. Sydney Davidson and Dr. Melanie Hennenfent understand that for many people, contact lenses provide greater convenience and more satisfying visual correction than eyeglasses.

A comprehensive eye exam comes first

Before being fit with contacts, you will undergo a comprehensive eye exam whereby the doctor determines your prescription and checks for any eye health problems that may interfere with successful contact lens wear.

IMPORTANT:  Your eyeglass prescription is not to be used to purchase contact lenses because of the risk of infection and damage to the eyes. Please read below to understand why a contact lens exam is required to safely wear these medical devices.

What to expect during a contact lens fitting in West Vancouver & Squamish, BC

First we will have a discussion to determine the best type of contact lenses for you, based on your lifestyle, personal preferences, and visual needs.

1. Special measurements are made

Just like a pair of shoes, we must fit a contact lens to your eye based on its unique size and shape. If a contact is fit improperly, you may experience discomfort or damage to your eye.

Corneal curvature: A keratometer is used to measure the curvature of your cornea (clear front surface of the eye). If your cornea is asymmetrical due to astigmatism, you may require a special lens design called a “toric” contact lens.

Corneal topography:  In some cases, detailed mapping of your cornea may be required. Corneal topography provides a very precise map of the corneal surface and its contours, allowing us to design a custom lens for your eye.

Tear film evaluation: Successful contact lens wear requires a healthy tear film to keep both the lenses and your cornea sufficiently hydrated. We may assess the quality of your tear film with yellow dye or the Tear Lab Osmolarity Test. If you have dry eyes, you may require lenses specialized lenses or a specific lens material.

2. Trial lenses are given

After the trial lenses settle on your eyes, the doctor will use the microscope to evaluate the position and movement of the contacts. If the lenses are comfortable and fit well, you will be sent home with a trial pair as well as instructions on how to insert and remove them, and how to care for your lenses.

3. Follow-up visit confirms safety & fit

Your follow-up visit will confirm that you are happy with your lenses, and that they are fitting well and not harming your eyes.  A yellow dye may be used to ensure the lenses are not damaging your cornea or making your eyes dry.  Often the doctor can see warning signs before you are aware of a problem with your contact lenses. If this occurs, the doctor may recommend a new lens material, different lens solution, or altered wearing schedule to keep your eyes healthy.

4. Contact lens prescription is finalized

After finding a contact lens that fits properly, is comfortable, and provides good vision, your doctor will then finalize your contact lens prescription.

Routine contact lens exams

Regardless of how often or how long you wear your contact lenses, your eyes should be examined at least once per year at one of our offices in Squamish and West Vancouver, BC to ensure your eyes are not being damaged by the lenses.
