We offer a variety of contact lens services at North York Eye Clinic. Our doctors fit and design specialty contact lenses.
What are specialty contact lenses? For people who have very high or uncommon prescriptions, past eye surgeries, eye diseases and/or conditions that cannot use soft contact lenses can benefit from a specialty or custom contact lenses.
Fitting contact lenses to correct or treat any of the above conditions will generally take much more time than a regular contact lens fitting. These “hard-to-fit” cases usually require a series of office visits and multiple pairs of trial lenses before the final contact lens prescription can be determined. Also, the lenses required for these conditions are usually more costly than regular soft contact lenses. Therefore, fees for these fittings are higher than fees for regular contact lens fittings.

SPECIALTY CONTACT LENSES
Contact Lenses for Astigmatism
If you have astigmatism – a common condition where the eye isn’t perfectly round, but more football- or egg-shaped – then you’ll need a special design of contact lenses called “toric” lenses for clear vision. Toric contact lenses are available in both soft and rigid gas permeable (RGP or GP) lens materials. Most contact lens wearers who need toric contacts choose soft toric lenses.
Bifocal/Multifocal Contact Lenses
Bifocal and multifocal contact lenses are designed to give you good vision when you reach your 40s and become presbyopic. Presbyopia is the normal loss of focusing ability up close when you reach your 40s. Beginning at this age, you may need to hold reading material – like a menu or newspaper – farther from your eyes to see it clearly.
Multifocal contact lenses and bifocal contact lenses have a range of powers that allow you to see at more than one distance. Just like bifocal or progressive eye glasses.
Bifocal and multifocal contact lenses are available in both soft and rigid gas permeable (GP) materials. Today, there are numerous designs of bifocal and multifocal contact lenses to correct presbyopia. During your contact lens fitting we can help you decide whether bifocal/multifocal contact lenses or monovision is best for you.
Scleral Lenses
Scleral lenses are large diameter lenses which vault over the entire corneal surface and rest on the “white” of the eye (the sclera).
Scleral lenses are used mainly to treat diseased and surgically altered corneas. Some conditions that are treated with scleral lenses include Dry Eye Syndrome, Keratoconus and corneal ectasias, Graft vs Host Disease- GVHD, Stevens Johnson Syndrome, Sjogren’s Syndrome, Post-LASIK, and Post- Corneal Transplant.
Rigid Gas Permeable Contact Lenses
Rigid gas permeable (RGP) contact lenses are rigid (hard) lenses made of durable plastic that transmit oxygen. These lenses are also called GP lenses, rigid gas permeable lenses (RGP) lenses and oxygen permeable lenses. RGP lenses transmit more oxygen to the eye than do traditional soft contact lenses.
RGP lenses also provide better vision, durability, and deposit resistance than soft contact lenses. RGP lenses can last for 1-2 years because they are very durable compared to soft contacts. They are made of materials that don’t contain water (as soft contact lenses do), so protein and lipids from your tears do not adhere to the lens as much. RGP lenses can be used for all prescriptions but are mostly utilized in patients with high prescriptions, high/irregular astigmatisms, and diseased or irregular corneas.
Keratoconus Lenses
Keratoconus is a relatively uncommon eye condition where the cornea becomes thinner and bulges forward. Gas permeable contact lenses are the treatment option of choice for mild and moderate keratoconus. Because they are rigid, GP lenses can help contain the shape of the cornea to prevent further bulging of the cornea. They also can correct vision problems caused by keratoconus that cannot be corrected with eyeglasses or soft contacts.
In some cases, a soft contact lens is worn under the GP lens for greater comfort. This technique is called “piggybacking.” Another option for some patients is a hybrid contact lens that has a GP center, surrounded by a soft “skirt”. Scleral lenses can also be used in some patients with keratoconus
