Recently, I met a new patient who had been living with keratoconus for many years. They had worn small-diameter gas permeable lenses for a long time but struggled with discomfort and dust constantly getting trapped under the lenses. Despite seeing multiple eye care providers over the years, they had never heard of scleral contact lenses, an option that can significantly improve vision stability, comfort, and performance across a variety of environments and lifestyles.
At Mission Eye Care, our doctors fit scleral lenses every single day, yet this story is not unique. It’s surprising how many Canadians have never heard of scleral lenses.
Scleral lenses are different from traditional contact lenses in one important way: They vault over the front surface of the eye instead of sitting directly on it. They rest on the white part of the eye, called the sclera, creating a smooth optical surface and a reservoir of fluid between the lens and your eye.
This design makes them a true game changer for many patients.
Who Are Scleral Lenses For?
They’re often used for people with:
Irregular corneas, such as keratoconus
Previous eye surgery, including LASIK complications
High or complex prescriptions
Chronic dry eye that has not improved with standard treatments
However, even patients who have simply never been happy with their vision in glasses or contacts may benefit.
Why are scleral lenses so effective?
Because scleral lenses create a perfectly smooth optical surface, they can dramatically improve vision that glasses or soft lenses cannot fully correct. At the same time, the fluid layer beneath the lens keeps the eye continuously hydrated, providing relief for many people with dry, irritated eyes.
Many patients describe the experience as seeing clearly and comfortably for the first time in years.
Are scleral lenses comfortable?
Despite being larger than regular contact lenses, scleral lenses are often more comfortable. Since they do not touch the sensitive cornea and remain stable throughout the day, most patients adapt quickly.
What is the process like?
Fitting scleral lenses is more customized than standard contacts. It involves detailed measurements and careful design to match the unique shape of your eye. This allows for a precise fit and the best possible vision and comfort.
Can scleral lenses help my dry eye?
Yes, scleral lenses can be an excellent option for patients with dry eye, especially when standard treatments have not provided enough relief. Because they vault over the cornea and hold a reservoir of fluid against the eye, they provide continuous hydration throughout the day. This can reduce irritation, improve comfort, and help stabilize vision that fluctuates due to dryness. While they are not necessary for every dry eye patient, they can be a powerful solution for more persistent or severe symptoms.
