Scleral Lenses
Scleral Lenses
Scleral lenses are a type of contact lens that vaults over the cornea and lands on the sclera, the white part of the eye, without touching the cornea. These lenses have gained popularity in recent years as they offer a variety of vision and comfort benefits compared to traditional contact lens options. Continue reading to learn everything you need to know about scleral lenses, including what they are, who they are best suited for, their benefits, and how to care for them.
What are Scleral Lenses?
Scleral lenses are large contact lenses that vault over the cornea and land on the sclera, the white part of the eye. These lenses are made of rigid gas-permeable (RGP) material, which allows oxygen to pass through the lens and reach the cornea. Unlike traditional contact lenses, which rest on the cornea, scleral lenses create a tear-filled reservoir between the lens and the cornea. This liquid or fluid reservoir acts as a cushion, providing optimal vision and protecting the cornea.
Who Are Scleral Lenses Best Suited For?
Scleral lenses are best suited for people with certain eye conditions, or people who have been unhappy with their previous soft contact lenses or RGP lenses, including:
Irregular Astigmatism
- Keratoconus
- Intacs
- Traumatic corneal injuries/scarring
- Pellucid marginal degeneration
- Post corneal transplant
- Post radial keratectomy (RK)
- Post LASIK/PRK
- Corneal dystrophies
Ocular Surface Protection

Benefits of Scleral Lenses:
Scleral lenses offer several benefits including:
- Improved Visual Acuity: Scleral lenses can improve visual acuity by correcting irregular astigmatism and other vision problems.
- Comfort: Scleral lenses are more comfortable than traditional contact lenses.
- Protection: Scleral lenses create a tear-filled reservoir that protects the cornea from damage and irritation.
- Long-Lasting Wear: Scleral lenses can be worn for longer periods than traditional soft contact lenses, making them ideal for people with dry eye syndrome or those who have experienced dry eye with their previous soft contact lenses.
- Customizable: Scleral lenses are customized to fit the size and shape of each individual’s eye, providing a more precise fit and optimal vision correction.
