Keratoconus alters the shape of the cornea and often makes correction with glasses insufficient. Keratoconus lenses—particularly rigid lenses and scleral lenses—are effective alternatives for restoring clear vision. This article explains the main options, the comfort they provide, and what patients say to help you choose the solution that best suits your needs.
Keratoconus lenses: what types are available and how do they differ?
Several types of lenses can be prescribed for keratoconus, depending on the corneal topography and the desired level of comfort.
Rigid lenses (rigid gas permeable lenses) effectively correct corneal irregularities by providing a regular optical surface; they may require a period of adjustment and specialized follow-up. To learn more about the fitting process and steps involved, read the article on
fitting rigid lenses for keratoconus.
Scleral lenses are larger: they rest on the sclera (the white part of the eye) and create a fluid-filled space between the lens and the cornea. This compensates for irregularities, provides greater
comfort for keratoconus for many patients, and maintains continuous hydration. To understand the personalized process
Scleral lenses are larger: they rest on the sclera (the white part of the eye) and create a fluid-filled space between the lens and the cornea. This compensates for irregularities, provides greater
keratoconus comfort for many patients, and maintains continuous hydration. To understand the customized fitting process, see our guide on

Keratoconus lenses: scleral vs. rigid lenses—comfort and visual outcomes
The choice between scleral and rigid lenses depends on several factors: corneal topography, tolerance to corneal contact, daily activities, and budget. Scleral lenses are often preferred for their comfort over long periods of time because they do not press on the cornea. On the other hand, rigid lenses can offer excellent optical quality, especially in moderate cases, and some gas-permeable versions improve permeability and comfort. For a technical overview of rigid options, you can read the article on
rigid gas permeable lenses.
Patient reviews show a growing preference for scleral lenses when comfort is a priority, while other patients choose rigid lenses for their optical performance. The price of lenses varies depending on the model, customization, and necessary follow-up care: it is important to factor the cost of fitting appointments and replacements into your budget. The final decision is made with your ophthalmologist and specialist optician, taking into account comfort, expected visual results, and practical constraints.
Keratoconus lenses now offer increasingly effective solutions: specially adapted rigid lenses, scleral lenses, and other customized options can significantly improve vision and everyday comfort. Consult a specialist—such as the Optics team in Fez—for a personalized assessment, a fitting session, and regular follow-ups to choose the lens best suited to your visual profile and lifestyle.
