Keratoconus Patient Diagnosed 40 years ago Receives GVR Scleral Lens

This patient was diagnosed with keratoconus in the early 1960's. 40 years ago he received a corneal transplant in his right eye and 20 years ago received a corneal transplant in his left eye. For 32 years he wore gas permeable lenses. While he was able to see relatively well with these lenses, they were painful to wear and would pop out of his eyes numerous times each day. Notice the profile photos of his corneas below. His transplanted corneas are so profound and the center of gravity is so far out that any gas permeable contact lens will not be stable on his eyes. 8 years ago we provided this patient with GVR Scleral lenses. These lenses are able to vault over the transplanted corneas and come to rest on the white portion of his eyes (the sclera). Because these lenses fit nicely under his eyelids and don't move, they are unable to be dislodged with normal eye movements. The interface between the back surface of the lenses and the front surface of the corneas is filled with sterile saline solution. In other words, his corneas are always in a liquid environment. This patient has been able to wear his lenses all day comfortably for over 8 years with excellent vision. Over these years, his corneas have remained clear and stable and have maintained their integrity.

Optimum Infinite Gas Permeable Material

I am happy to announce that our Global Vision Rehabilitation Center will be designing and fitting all of our “high need” patients with the Optimum Infinite gas permeable contact lens material. The Optimum Infinite material is the most oxygen permeable material ever to be approved by the FDA. In addition, this newly FDA approved material includes a UV lens blocker. Now for the first time, with certain patients, wearing a scleral lens made with the Infinite material under extended wear conditions can be considered.

SMAP 3D Scleral Lens Design

NEW: Powerpoint presentation on SMAP 3D

Last year we introduced an exciting piece of technology that has allowed us to custom design a scleral lens much more accurately. It is the SMAP 3D, which is a computer attached to a dedicated camera that allows us to obtain a 3 dimensional image of the entire front surface of the eye, including the cornea and the surrounding white portion of the eye (the sclera). Up until now there has not been any technology that would allow us to measure the ocular curvatures outside the cornea. The SMAP allows us to do this. Read More

Blurred Vision, Burning Eyes: This Is a Lasik Success?

EyePrint Pro

EyePrintPro technology creates a scleral lens based on a mold of the cornea. The molding is accurate to 1 or 2 microns and fits perfectly because it exactly mirrors the irregularities of the individual corneal surface. The technology is well suited for post-Lasik, Keratoconus, RK, eye injury, and corneal transplant patients. Read More in this PDF about EyePrintPro Scleral Lens Technology
