GVR Scleral Lens over Highly Irregular Cornea

This cornea is so profound and it’s corneal surface so irregular that eyeglasses and conventional contact lenses cannot provide this eye with functional vision. The only lens technology that will provide this eye with functional vision is a 20 mm gas permeable GVR Scleral lens. With the GVR Scleral lens this eye has 20/25 vision. Without this lens, this eye has less than
20/800 vision.
