What Are Scleral Lenses?
Though most patients can comfortably and successfully wear conventional contact lenses to correct their vision, there are a significant number of patients that require specialty customized contact lenses. If you have complex eyes due to an eye condition or injury, or you have been told that you are not a good candidate for conventional contact lenses, scleral contact lenses may be the right choice for you.
Scleral contact lenses are able to improve vision with exceptional comfort while also reducing dryness, pain and glare for patients suffering from various ocular disorders or injuries to the eye. Scleral lenses have been highly successful in patients with Keratoconus, corneal degenerations, Dry Eye Syndrome, post-LASIK/PRK/RK and corneal transplants.
So, what are Scleral Lenses?
Scleral lenses are custom-designed, large-diameter, rigid gas-permeable lenses that completely cover the corneal surface (clear layer covering the colored part of the eye) and extend onto the scleral conjunctiva (white part of the eye).
Who would Benefit from Scleral Contact Lenses?
Patients diagnosed with any of the following conditions may benefit from Specialty Scleral Contact Lenses:
Pellucid marginal degeneration
Post-LASIK, post-PRK, post-RK
Graft versus host disease
Moderate to Severe dry eyes syndrome (Keratoconjunctivitis Sicca)
Corneal ectasia and scarring
High or irregular astigmatism
Other corneal degenerations and dystrophies
What are the Benefits of Scleral Contact Lenses?
1. Clear Vision
The design of these Scleral contact lenses allows the lens to maintain its uniform and regular curvature as it lies over the cornea without touching or conforming to the existing corneal shape as soft contact lenses do. Therefore, the corneal surface, as well as any irregularity that it may have, is masked by the dome-shaped even surface of the lens allowing the light to enter the eye and focus images clearly instead of in a distorted manner.
2. Unprecedented Comfort
Scleral contact lenses offer better comfort than corneal rigid contact lenses because Scleral lenses land on a much less sensitive layer of the eye and thus decrease lens awareness and sensation. The Scleral contact lens edge is tucked underneath the eyelids allowing the eyelids to glide over the smooth surface of the Scleral contact lens during every blink instead of bumping into the edge of the contact lens. Scleral contacts also have greater stability than corneal rigid lenses, allowing for less movement of the contact lens and better comfort.
3. Dry Eyes
It can be common to have dryness with contact lens wear, especially if you are already diagnosed with chronic dry eye syndrome or keratoconjunctivitis sicca. In the case of Scleral contact lens wear, there is a fluid layer in between your cornea and the lens that serves as a liquid reservoir or a cushion layer. This allows your cornea to be constantly protected and hydrated decreasing the symptoms associated with dry eyes.
4. Reduced Glare
Scleral lenses dedicate a large central area of the lens to your prescription that remains in a stable position over the pupil (central black part of the eye). The stability and the size of the area containing your prescription reduces the amount of glare that is experienced. This is a beneficial feature especially for those who have issues with night time driving glare as well as athletes. Corneal lenses, however, are smaller than Scleral lenses. This means there is less surface area devoted to your prescription and the lens is more likely to move around with every blink, thus causing less stability of clear vision and increased glare.
Many individuals who are wearing Scleral contact lenses have damaged corneal tissue. Scleral lenses do not make any contact with the cornea and instead have a fluid barrier in between the lens and the corneal tissue, providing a source of protection.
