SPECIALTY CONTACTS
SPECIALTY AND CUSTOMIZABLE CONTACT LENSES IN EDMONTON
Specialty contact lenses are custom-fit contact lenses that are typically used for "hard-to-fit" eyes. They require a high level of expertise and training from the eye doctor to fit and design, as well as specialized equipment to ensure a proper fit. Specialty contact lenses are especially beneficial for individuals with complex vision needs, such as those with irregular corneas or high levels of astigmatism. These lenses can provide improved comfort and vision quality compared to traditional spectacle lenses or regular soft contact lenses. It's important to consult with an eye care professional to determine if specialty contact lenses are the right option for your specific eye care needs.
WHO ARE SPECIALTY CONTACT LENSES FOR?
Specialty contact lenses can be a suitable option for those seeking an alternative to glasses. When properly fitted, these lenses offer several advantages over traditional soft contact lenses. For certain conditions however, specialty contact lenses may be the ONLY viable option. These conditions include Keratoconus, Corneal Transplants, complications following refractive surgery (such as ectasia or irregular astigmatism), Corneal Scarring, Ocular Trauma, Moderate/Severe Dry Eye Disease, Naturally Irregular Corneas, Pediatric Conditions, and Contact Lens Intolerance/Discomfort.

It is important to work with a qualified eye care professional to determine the best course of treatment for your specific needs.
SCLERAL LENSES
Scleral lenses are rigid contact lenses with a large diameter that cover the entire cornea and rest on the white part of the eye (sclera). This design provides exceptional vision and comfort for patients. Dr. Natalie Chai specifically recommends scleral lenses for individuals with keratoconus and other corneal irregularities, as they can effectively correct vision problems and reduce discomfort. Due to their unique design, scleral lenses can also help protect the cornea and promote healing in some cases. It's important to consult with an experienced eye care professional to determine if scleral lenses are the right option for your specific needs.
HYBRID LENSES
Hybrid contact lenses were developed as an alternative to traditional rigid gas permeable (RGP) lenses, which can be uncomfortable. These lenses feature a GP center for clear vision, along with a soft lens "skirt" for added comfort. This combination of materials offers the best of both worlds and has made hybrid lenses a popular choice for patients who may be hesitant to try traditional RGP lenses due to discomfort. Hybrid lenses are a great option for vision correction for both normal and irregular corneas. They provide excellent visual acuity and can improve overall comfort compared to other rigid contact lens options. It's important to work with an experienced eye care professional to determine if hybrid lenses are the right fit for your specific needs.
ORTHOKERATOLOGY (ORTHOK)
Orthokeratology lenses are primarily used for myopia management, as they are designed to gently reshape the cornea while the wearer sleeps. These specially designed hard lenses incorporate a reverse geometry design and can help slow down the progression of myopia. The added bonus is that children can be free from glasses and contact lenses during the day. Orthokeratology is also an excellent option for individuals who are apprehensive about undergoing permanent refractive surgery or who face financial barriers to surgery. Orthok provides similar results to refractive surgery but is a safe, reversible treatment at a fraction of the cost. However, it's essential to note that orthok is not used for myopia management in adults.
RIGID GAS PERMEABLE (RGP) LENSES
Rigid gas permeable (RGP) contact lenses are made of silicone-containing compounds and are typically harder than soft contact lenses. Though not as common as soft lenses, there are some patients, known as “legacy” patients, who have only worn RGP lenses and require ongoing care to maintain them. RGP lenses offer several advantages over soft lenses. They allow for a high percentage of oxygen permeability, promoting excellent eye health. This material also helps to maintain the shape of the lens, resulting in sharper visual acuity. Furthermore, RGP lenses are more durable and resistant to tears than soft lenses, and they are generally easier to keep clean and maintain. While RGP lenses may not be as popular as soft lenses, they can be a great option for certain individuals. It's important to consult with an experienced eye care professional to determine if RGP lenses are the right choice for your specific needs.
