In today’s ever-evolving world of eye care, innovation continues to transform how we correct and protect our vision. One of the most significant developments is scleral contact lenses. These lenses are larger than traditional contact lenses and rest on the sclera, or white part of the eye, rather than directly on the cornea.
Scleral lenses’ unique design allows them to provide a stable, smooth optical surface and a cushion of moisture between the lens and the eye. For individuals with complex vision needs or dry eye, they offer clarity and comfort that traditional lenses often can’t match.
What are Scleral Contact Lenses?
Scleral contact lenses are large-diameter gas-permeable lenses designed to vault over the cornea and rest on the sclera—the white part of the eye. Unlike traditional contact lenses that sit directly on the cornea, scleral lenses leave a space between the lens and the eye’s surface. This space is typically filled with sterile saline solution, which keeps the cornea hydrated and creates a smooth surface for light to enter the eye.
The result? Clearer, more stable vision—particularly for individuals with irregular corneas or severe dry eye. These lenses are custom-designed to match the unique shape of your eye, offering both comfort and precision in visual correction.
Types of Scleral Contact Lenses
Scleral lenses are available in various sizes, each tailored to a specific set of needs. The larger the lens, the more of the eye it covers.
Corneo-Scleral Lenses
These smaller scleral lenses range from 13 to 15 mm in diameter. They offer more coverage than standard gas-permeable lenses, making them useful for mild corneal irregularities or for patients transitioning from traditional contact lenses.
Mini-Scleral Lenses
Measuring around 18 mm, mini-sclerals cover the entire corneal surface and extend slightly onto the sclera. They are ideal for patients dealing with moderate levels of corneal irregularity or chronic dry eye.
Full Scleral Lenses
These lenses are the largest, ranging from 19 to 24 mm in diameter. Full sclerals offer maximum coverage and are often an excellent choice for those with advanced corneal conditions, such as keratoconus, severe ocular surface disease, or post-surgical complications.
Who Are Scleral Lenses For?
Scleral lenses are designed for people with complex or “hard-to-fit” eyes. If you’ve been told that traditional contact lenses won’t work for you, scleral lenses may offer a comfortable and effective solution.
They are often recommended for individuals with:
- Keratoconus or other corneal irregularities
- Severe dry eye syndrome
- Post-surgical corneas (e.g., post-LASIK or corneal transplants)
- Chronic eye irritation or exposure sensitivity
- Difficulty wearing soft contact lenses comfortably
Scleral lenses are also a good fit for people with active lifestyles. Because of their stability and larger diameter, they are less likely to shift or fall out during sports or physical activity.
Key Benefits of Scleral Lenses
Long-Lasting Comfort
Thanks to the fluid reservoir between the lens and the eye, scleral lenses provide consistent moisture throughout the day. This makes them a top choice for individuals with dry eye, corneal sensitivity, or those who work in dry or windy environments.
Clearer, More Stable Vision
Scleral lenses create a smooth, uniform surface over the cornea, correcting irregularities that can distort vision and improve overall visual acuity. They can be particularly effective for patients whose vision can’t be corrected with glasses or soft lenses.
Increased Lens Stability
Their larger size means they’re more stable on the eye compared to smaller contact lenses. This helps reduce shifting or dislodging, leaving you with reliable vision from morning to night.
Extra Eye Protection
Scleral lenses cover a larger portion of the eye’s surface, providing an additional layer of protection from dust, allergens, and wind. This is particularly beneficial for people with outdoor jobs or hobbies.
