Specialty Contact Lenses Available at North York Eye Clinic
RGP - Rigid Gas Permeable contact lenses
The doctors at North York Lenses can customize and order RGP lenses for your visual needs. RGP stands for Rigid Gas Permeable. RGP lenses are a type of contact lens that is made of a rigid plastic material that allows oxygen to pass through it. They are also sometimes called "hard contact lenses" or "gas permeable lenses."
RGP lenses are designed to provide clear vision and are often used to correct a variety of eye conditions, including nearsightedness, farsightedness, and astigmatism. They are usually custom-made to fit the specific shape and size of an individual's eye.
Compared to soft contact lenses, RGP lenses are more durable and can last longer with proper care. They also provide better oxygen flow to the eye, which can help maintain eye health. However, they can take some time to get used to and may initially feel uncomfortable. It is important to follow the instructions of an eye care professional for proper cleaning and care of RGP lenses to ensure their effectiveness and longevity.
RGP (Rigid Gas Permeable) lenses are a type of contact lens that are made of a firm, durable plastic material that allows oxygen to pass through to the cornea. Here are some of the benefits of RGP lenses:
- Better vision: RGP lenses provide sharper, clearer vision than soft lenses, especially for people with astigmatism or other irregularities in the shape of their cornea.
- Longer lifespan: RGP lenses are more durable than soft lenses, so they last longer and are less likely to tear or wear out.
- Better comfort: Because they allow more oxygen to reach the eye, RGP lenses are generally more comfortable to wear than traditional hard lenses.
- Reduced risk of infection: RGP lenses are less likely to harbor bacteria and other microorganisms that can cause eye infections.
- Fewer lens replacements: Because RGP lenses are more durable, they require fewer replacements than soft lenses, which can save you money in the long run.
- Can slow progression of myopia: In some cases, RGP lenses may help slow the progression of myopia (nearsightedness) in children and young adults.
Overall, RGP lenses offer several benefits compared to soft lenses, including better vision, durability, comfort, and reduced risk of infection. However, they do require a period of adaptation and may take longer to get used to than soft lenses. Please call our office today at 647-352-5553 to book a fitting and consultation appointment.
Keratoconus RGP Lenses
Keratoconus is an eye condition in which the cornea (the clear front surface of the eye) becomes thin and bulges outward into a cone shape. Rigid Gas Permeable (RGP) lenses are a type of contact lens that are made of a rigid plastic material which allows oxygen to pass through to the cornea.
Keratoconus RGP lenses are a type of contact lens designed specifically for people with keratoconus. These lenses are often used because they can help to correct vision in people with irregularly shaped corneas caused by keratoconus. The rigid material of RGP lenses helps to hold the cornea in a more normal shape, which can improve vision.
Keratoconus RGP lenses are usually custom-made to fit the unique shape of the individual's cornea, as each case of keratoconus is different. They can also be designed to correct other vision problems, such as astigmatism or nearsightedness.
Overall, RGP lenses can be a good option for people with keratoconus who are looking to improve their vision and quality of life. However, they may take some time to get used to, and may require regular adjustments or replacements to ensure optimal fit and vision correction.
At North York Eye Clinic, we offer keratoconus patients the Rose K and Rose K2 lenses from Blanchard that are specially designed for patients who have keratoconus or irregular contact lenses. Please call our office at 647-352-5553 to book a keratoconus lens consultation and fitting.
Rose K2™ and Rose K™ lenses are dispensed the world over, to correct Keratoconus. Featuring a systematic approach to fitting and a flexible edge lift, posterior aspheric optics provides aberration control for improved vision, enhanced contrast, and comfort. The Rose K family of lenses includes many designs to fit all corneal shapes, sizes and irregularities.
Indications for Rose K lenses may include: Keratoconus, Pellucid Marginal Degeneration, Keratoglobus, Moderate and Steep Nipple Cones, LASIK induced Ectasia, Post Graft, and patients who have undergone Penetrating Keratoplasty. The approach to fit all of the lenses follows a simple systematic approach. The proven “Systematic Approach to Fitting” applies to all Rose K designs and allows for a final lens choice in a shorter period of time (fewer office visits). They provide better vision performance while maintaining optimum corneal health.
RGP vs. Hybrid vs. Scleral Contact Lenses
RGP and Scleral Contact Lenses
Scleral contact lenses
Scleral contact lenses are a type of large-diameter contact lens that are designed to cover the entire cornea and rest on the white part of the eye, which is called the sclera. They are made of a gas permeable material that allows oxygen to pass through to the cornea, which can help improve comfort and reduce the risk of complications associated with traditional contact lenses.
Scleral lenses are typically prescribed for people with certain eye conditions, such as keratoconus, irregular astigmatism, or severe dry eye syndrome. They can also be used to correct vision after a corneal transplant or other types of eye surgery.
One of the benefits of scleral lenses is that they create a liquid reservoir between the lens and the cornea, which can help protect the cornea and improve vision for people with certain eye conditions. However, scleral lenses require a special fitting process and may take some time to get used to wearing. It's important to work closely with an eye care professional to determine if scleral lenses are a good option for you and to receive proper instructions on how to care for and wear them.
Rigid gas permeable (RGP) lenses and scleral lenses are both types of contact lenses, but they differ in several ways:
- Size: RGP lenses are typically smaller than scleral lenses, with a diameter of around 9-10 mm, while scleral lenses have a diameter of 14-18 mm.
- Fit: RGP lenses sit directly on the cornea, while scleral lenses rest on the sclera and vault over the cornea. This makes scleral lenses more comfortable for people with irregularly shaped corneas or those who have undergone certain eye surgeries.
- Use: RGP lenses are commonly used for correcting vision, while scleral lenses are often used for medical purposes, such as for people with keratoconus, severe dry eye syndrome, or corneal irregularities.
Overall, scleral lenses tend to be more comfortable and provide better vision for people with certain eye conditions, while RGP lenses are typically used for routine vision correction. However, both types of lenses require careful fitting and regular monitoring by an eye care professional to ensure they are effective and safe for the patient.
At North York Eye Clinic, we offer OneFit Scleral contact lenses from Blanchard and the ICD FlexFit Scleral lenses from Cardinal Contact Lenses. Please call our office at 647-352-5553 to book a consultation.
