What are Scleral Lenses?

We welcome you to call us at 770-409-8977 to discuss your needs and assess whether scleral lenses are right for you.
Scleral contact lenses are an extra-large type of rigid gas permeable lenses. Unlike traditional contacts, scleral lenses vault over the entire cornea, leaving a gap between the lens and the corneal surface. They rest on the white part of your eye (your sclera).
Their unique design makes scleral lenses among the most comfortable contacts around, providing excellent vision for people of all ages
They are particularly useful for managing eye conditions such as:
-
Keratoconus
-
Astigmatism
-
Dry Eyes
-
Giant papillary conjunctivitis (GPC)
-
Post-refractive surgery (i.e. LASIK, PRK)
-
Presbyopia
Advantages Of Wearing Scleral Lenses
With scleral lenses, you’ll experience consistently clear vision—even if you have an irregular cornea. Here are some of the benefits provided by scleral lenses:
-
Super-size diameter: This helps them stay centered and stable on your eye, and prevents them from popping out easily.
-
Made from high-quality materials: This means they'll last for the long haul.
-
Protects against allergies: The large size of the lens blocks debris, dust, and allergens.
-
Highly breathable: Gas permeable material ensures ample oxygen reaches the eye.
-
Lubricating Cushion: They have a pocket that fills with moisturizing tears, for a very comfortable wearing experience, and healthier eyes.
Ready to say goodbye to all those contact lenses that felt uncomfortable and didn’t give you sharp vision? Call Us in Atlanta for more info.

Scleral Lenses for Keratoconus Treatment in Atlanta
One of the most common conditions that scleral lenses help to address is keratoconus. This condition occurs when the normally round, clear part at the front of the eye, the cornea, begins to thin and bulge into a cone or football-like shape. This can severely harm your vision. Symptoms include:
-
Blurred or distorted vision
-
Sudden worsening or clouding of vision
-
Increased light sensitivity
How Do Scleral Contact Lenses Help With Keratoconus?
Before putting them in, scleral lenses are filled with a preservative-free saline solution that creates a fluid reservoir that helps mask many of the irregularities on the cornea, which helps to improve vision.
The scleral lens also corrects vision by vaulting over the cornea and resting on the white part of the eye known as the sclera. This allows the lens to form a smooth refracting surface over the uneven or warped cornea, focusing light more accurately at the back of the eye.
Vision With Keratoconus: Glasses or Soft Contacts vs. Sclerals
Patients with milder keratoconus can actually do quite well in very specific soft contact lenses and glasses. But for the most part the optics of hard contact lenses like scleral lenses and gas permeable (RGP) lenses are typically superior to glasses or soft contact lenses because they help mask a lot of the irregularities on the surface of the cornea.
So, typically if a patient with moderate to severe keratoconus wears normal soft contact lenses or glasses, they’d experience a lot of visual distortion, glare and halos around lights, specifically at night time, and double vision. Scleral lenses help reduce these and other vision issues that can severely impact the clarity of their vision.
