What is a scleral contact lens?
A scleral lens is a large diameter gas permeable lens that is designed to bridge the entire cornea and sit on the sclera of the eye. Due to the large size, it is more comfortable and stable than a traditional rigid gas permeable (RGP) lens. By bridging the cornea, they create a large, smooth surface and can improve the vision of those with corneal irregularities such as Keratoconus, astigmatism, Corneal Ectasia or corneal problems after lasik surgery.
What are the benefits of Scleral contact lenses?
Scleral lenses are large, stable, lenses that can provide the most stable and excellent vision. Because they vault over the cornea, there is a layer of tear film over the corneal surface, which bathes the eye in fluid. This fluid keeps the eye lubricated and comfortable. The large size of the lens maintains balance and little movement of the lens on the blink. Consistently clear vision is possible. Scleral lenses can be custom designed and personalized for each patient. Many aspects of the lens can be tweaked to improve both vision and comfort. While the process can be long and time-consuming, the end result is worthwhile.
Who would benefit from Scleral contact lenses? Those with irregular corneas.
Scleral lenses are the best for patients with Keratoconus, High distance prescriptions, lots of astigmatism, corneal problems after transplant or after Lasik surgery. Patients with extreme dry eye or hard-to-fit prescriptions can be successful scleral lens wearers. Additionally, Those who have previously worn rigid gas permeable (RGP) lenses love the crisp vision and significantly improved comfort from scleral contact lenses. Athletes who need precision in their sports such as baseball pitchers may also benefit. Lastly, patients who have previously been unsuccessful in contacts due to either comfort or vision may be successful scleral lens wearers.
Many insurances plans may also cover scleral contact lenses for the right candidate.
