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.

This is a photo of an eye with an advanced keratoconus. Over this cornea there is a GVR Scleral lens. The milky-white haze
in the center of the cornea is a condition known as hydrops. This occurs when the cornea is so profound that the
most posterior layer of the cornea tears as a result of the pressures within the eye. Conventional contact lenses or
eyeglasses will not allow this eye to see clearly. With the GVR Scleral lens, this eye has 20/30 vision. Without this
lens, this eye has less than 20/800 vision.

This is a photo of a GVR Scleral lens on an eye with advanced keratoconus. With this lens, this eye can see clearly (20/20) with all day lens wear. Without this lens, the best vision that this eye can attain is less than 20/800.
