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.
