Contact Lenses Fitting
We are internationally recognized for our expertise in the contact lens field. Our practice has access to virtually every commercially available lens from any company. Complicated cases like astigmatism, keratoconus and bifocal lenses, as well as coloured contact lenses for both fun and serious cosmetic purposes can all be assessed for contact lens suitability and in most cases successfully fitted.
Although contact lenses have been around for more than 40 years, the past decade has seen tremendous developments in lens materials and design to bring even greater benefits to contact lens wearers. Today almost all eyesight problems can be corrected with contact lenses. Contact lenses offer considerable advantages over glasses providing a larger field of view with reduced magnification or minification. They?re excellent for sports and can be fitted to most patients with any prescription.
If you are interested in correcting your vision through surgical methods, we'll help you understand all of the advantages and disadvantages of the procedures currently available. After an eye examination to determine your suitability for surgery, if you meet the candidacy requirements, we will perform all necessary pre-operative tests, arrange for your surgery with surgeons who specialize in this field and provide you with the finest follow-up care in our advanced clinic.
New manufacturing technology has also made contact lenses more affordable than ever before.

WHAT IS A LENS FITTING?
It's important to realize that contact lenses are medical devices designed specifically for your eye and need to be properly fitted by an eye care practitioner. If you are interested in wearing/getting contact lenses, the first thing you need to do is have a complete eye exam. This is necessary even if you don't normally wear glasses and just want contacts to change your eye colour.
The prescription you receive at the end of your exam is typically a prescription for eyeglasses only. An accurate prescription for contact lenses can only be issued after a contact lens fitting, which involves several steps that are not included in a routine eye exam:
- Special measurements of the curvature of the front surface of your cornea
- Evaluation of the tear film on the front of your eyes
- Assessment of corneal health
- Exam with trial lenses in place to assess fit
- Education regarding guidelines for wearing and caring for lenses
Patients who have previously tried contact lenses without success may find that there is now a more modern lens that offers superior comfort and vision correction. For this reason, it's always worth having a discussion with your eye care practitioner even if previous attempts at contact lens wear have failed.
Additional consultations are often required to check that the contact lenses fit well when they have settled on the eyes after a few hours wear and to ensure that there have been no detrimental effects. Regular aftercare appointments are important to monitor the contact lens prescription and health of the eyes.
Even though just about everyone can wear contacts, a contact lens exam can tell if you're one of the few who can't and your doctor will be able to discuss the lens options that would work best to correct your vision.
BRANDS AND TYPES
- There are several types of contact lens options available to correct the most common vision problems:
- Rigid or "Hard" Lenses: These are made of a type of plastic called PMMA (polymethyl methacrylate) and are very durable, but the least comfortable lens and are therefore not are popular as newer lens styles.
- Gas-permeable Lenses: Also known as "RGPs," these are newer rigid or "hard" lenses made of plastics combined with other materials, such as silicone and fluoropolymers, which allow oxygen in the air to pass directly through the lens.
- Soft Lenses: These lenses are made of plastic materials that incorporate water. The water makes them soft and flexible, as well as allowing oxygen to reach the cornea.
- Disposable Lenses: These are the most common type of lens and are worn for a specific period of time, then thrown out and replaced with fresh lenses.
- Extended Wear Lenses: Disposable lenses that can safely be worn for longer periods of times, usually one to several days.
- Toric Lenses: Designed specifically to correct vision and astigmatism.
- Bifocal Lenses: Provide good vision to patients who have problems seeing at near distances.
- Multifocal Lenses: Has a range of prescription powers within each lens, correcting distance at near, far and in between distances.
- Monovision: wearing a contact lens on one eye to correct your distance vision and a contact lens on your other eye to correct your near vision.
- Orthokeratology Lenses: Often referred to as ortho-k, these are special contact lenses worn during sleep to reshape the surface of your eye, so you can see clearly even after you remove the lenses. The effect is temporary, and lenses must be worn each night to maintain the effect.
- Coloured Lenses: Available with or without a prescription, these lenses give your eyes a subtle or dramatic change. Coloured contact lenses come in three options: visibility tints, enhancement tints, and opaque colour tints.
