GP Contact Lenses
Specialist in Kansas

For those needing specialty contact lenses, scleral lenses are often the recommended option. Among these, EyePrintPRO stands out as the most customizable and highest-performing scleral contact lens available. However, while EyePrintPRO offers top-tier performance, it may not always be necessary, as other viable alternatives may be available to patients.

During the initial comprehensive exam, Dr. Letourneau will use advanced technology and his extensive experience to determine if EyePrintPRO is essential or if other options may suffice.

If you have any questions about EyePrintPRO, feel free to reach out to us at (913) 261-8327 for our Olathe location or (785) 268-6880 for our Lawrence Location. More information about EyePrintPRO is available below.

What is Gas Permeable
(GP) Contact Lenses?

Gas permeable (GP) lenses, also known as rigid gas permeable (RGP), corneal GPs, or simply “hard” lenses, have been a trusted option in specialty contact lens care for decades. Though they may go by many names, all GP lenses share a core feature: they are made from a firm yet breathable plastic material that allows oxygen to pass through to the cornea, helping to maintain ocular health and comfort. Unlike soft lenses, which mold to the shape of the eye, GP lenses retain their form. This rigidity creates a smooth optical surface over irregular corneas, offering sharp, stable vision even when the cornea is misshapen or scarred. While they may take some time to adapt to initially, many patients find that the long-term vision quality and durability of GP lenses make them a valuable solution.

Who Are They For?

GP contact lenses are a great fit for patients who haven’t had success with traditional soft contacts, standard glasses, or even some types of specialty lenses. They are especially effective for individuals with:​​​​​​​

High astigmatism
GP lenses neutralize irregular curvature by maintaining a consistent shape on the eye.

Keratoconus or corneal ectasia
Where the cornea becomes cone-shaped or uneven.

Corneal scarring or post-surgical eyes
Such as after radial keratotomy (RK), LASIK, or other surgeries that disrupt the corneal surface.

Irregular corneal surfaces
Where soft lenses may not provide adequate visual correction.

What Are The Benefits?

Consistently Clear
Vision GP lenses don’t flex or conform to the eye’s irregular surface like soft lenses. Instead, they create a uniform refracting surface over the cornea, correcting distortion and improving visual clarity, even in challenging cases like keratoconus or surgical scarring

High Oxygen Permeability
Made from advanced breathable plastics, GP lenses allow oxygen to reach the cornea, promoting healthier eyes during long-term wear.

Durability and Cost-Effectiveness
GP lenses are more durable than soft lenses and can last for a year or more with proper care. Though they may require a short adjustment period, they often provide better value over time due to their longevity.

Customization
GP lenses can be customized in shape, size, and power, allowing practitioners to design lenses for complex prescriptions or unique eye conditions.

GP Lenses VS. Scleral Lenses
Which is right for you?

Patients who wear GP lenses sometimes explore scleral lenses as an alternative, especially if they experience discomfort or instability with corneal GPs. While both lenses are designed for complex vision correction, their designs and fit differ significantly:

  • GP lenses rest directly on the cornea and are smaller in diameter.
  • Scleral lenses vault over the entire corneal surface and rest on the white of the eye (the sclera), often offering enhanced comfort and hydration.

At the Contact Lens Institute of Kansas, Dr. Letourneau and our experienced medical team will guide you through the benefits and limitations of each lens type. Using advanced diagnostic tools and precise fitting technology, we’ll help you find the ideal balance of clarity, comfort, and long-term eye health.

FABULOUS!!! Quick and VERY efficient. Doctor and staff VERY friendly. When I walked through the doors I was met with a very warm and welcoming staff member. When the Dr was finished, Julian walked with me to the lobby, fixed my broken glasses and was extremely helpful in picking out my new glasses, in fact I had 3 staff members helping me! They were all sooo extremely nice! Thank you!!!!

Ridgeview Eye Care-Olathe is be the best! They have the best customer service around. My glasses of 5 months were broken and not repairable, I went in for help and they reordered the lenses under my warranty, but the frame still did not sit right. My daughter was getting married in just over a week and Lauren told me they would do whatever it takes to get my glasses repaired. 6 days later I got a call that my glasses were ready, I went to pick them up and they had a new pair just in time for me to see my daughter walk down the aisle; this means the world to me that they worked so hard to make this happen. Thank you Ridgeview Eye Care!
