Rigid Gas Permeable (RGP) lenses are the ideal solution for addressing irregular corneas and achieving sharp vision. Tailored specifically for your unique needs, these lenses enhance eye health and visual clarity.
Rigid Gas Permeable (RGP) lenses are specialty contact lenses tailored to address irregular corneas that other lens types struggle to fit properly. These lenses are made from a durable, oxygen-permeable plastic that helps create a smooth optical surface, essential for clear, consistent vision. By correcting irregularities on the cornea, RGP lenses offer patients sharper vision and sustainable eye health over time.
Irregular corneas can result from conditions such as keratoconus, post-surgical changes, or other corneal deformations. When the natural shape of the cornea is inconsistent, light is refracted unevenly, leading to distorted or blurred vision. RGP lenses excel in these situations by providing a rigid, smooth refractive surface that masks these irregularities, resulting in improved clarity and visual performance.
Unlike soft lenses that conform to the shape of the eye, RGP lenses maintain their form on the cornea. Their unique design offers several significant benefits:
When an RGP lens is carefully fitted to an irregular cornea, its rigid surface creates a smooth refractive interface. The tear film that builds up under the lens acts as a liquid lens, filling in the gaps created by corneal irregularities. This phenomenon diminishes higher-order aberrations—complex distortions in the way light enters the eye—resulting in sharper, more consistent vision. In essence, the RGP lens masks the imperfections of the cornea by providing a uniform surface through which light can be accurately focused.
Patients are often recommended RGP lenses when their corneas are irregular due to inherent anatomical variations or as a result of conditions such as keratoconus. They are particularly advantageous when soft lenses are unable to provide the necessary level of visual correction because of their tendency to mold to the irregular corneal surface. Our eye doctors carefully assess each patient’s unique needs to determine whether RGP lenses will offer the best visual outcomes.
Individuals who may benefit most from RGP lenses include those with:
Here’s the thing: when vision correction is compromised by irregular corneal shapes, the precision and stability provided by RGP lenses can make a world of difference.

The journey to achieving optimal vision with RGP lenses begins with a comprehensive eye examination. Our eye doctors use advanced diagnostic equipment, such as corneal topographers, to carefully map the shape of your cornea. This detailed mapping ensures that every parameter—ranging from the base curve to the lens diameter—is measured with precision, which is critical in custom tailoring an RGP lens that fits safely and comfortably.
During the fitting process, you will initially be provided with diagnostic trial lenses. These lenses allow our eye doctors to assess the lens fit, comfort, and visual acuity. A proper fit involves ensuring that the lens sits lightly on the cornea, with an even distribution of pressure and a smooth tear film underneath. This “three-point touch” approach, where light contact is achieved at key areas, is particularly important for patients with significant irregularities, as it helps prevent complications like corneal staining or discomfort.
Adjustments to parameters such as the base curve or overall lens design may be needed during the fitting process to ensure that the lens meets each patient’s unique needs. Once the proper fit is achieved, patients are educated on safe insertion, removal, and care techniques, ensuring that the lenses continue to provide excellent vision and comfort. This personalized approach is at the heart of why RGP lenses are such an effective solution for irregular corneas.
Proper care and regular follow-ups are vital to the success of wearing RGP lenses, especially for those with irregular corneas. Because these lenses are custom-made and designed to maximize oxygen flow, maintaining a routine cleaning and checkup schedule is essential. Our eye doctors emphasize the importance of annually scheduled eye examinations to ensure that the lenses continue to fit properly and that your corneal health remains intact.
Here are some key tips for maintaining your RGP lenses and eye health:
Taking these steps not only optimizes the performance of your RGP lenses but also greatly reduces the risk of complications that may arise from irregular corneal conditions.
