Recommended replacement: Every 2 to 4 years.
Scleral Lenses are large diameter (over 15.5mm) gas permeable lenses.
They are custom made lenses that vault over the cornea to rest on the sclera (the white part of your eyes), creating a smooth spherical refractive surface.
These lenses are very stable on the eyes with better initial comfort.
They are suitable for patients with corneal irregularities, Keratoconus, Post Graft, surgery induced ectasia and dry eyes.
