Advanced Keratoconus 20/20 with GVR scleral lens

This is a photo of me with Anthony, a patient with a very advanced case of keratoconus. Anthony was diagnosed with keratoconus many years ago. Over the years he was unable to wear any type of contact lens comfortably. With all of the lenses that Anthony was given prior to visiting our office, he was either able to see clearly but with great discomfort, or have excellent comfort but with poor vision. None of Anthony's prior lenses gave him excellent vision while at the same time giving him good comfort. 7 years ago we fit Anthony with GVR lenses. For about 4 years he was able to see clearly and comfortably. Several years ago, Anthony's left eye developed a condition known as "hydrops". This is a condition that develops when the most posterior corneal membrane ruptures allowing fluid within the eye to enter the cornea creating a cloudy appearance. This condition can occur when the pressures within the eye against the weakened cornea causes a break in Descemet's membrane, the most posterior corneal membrane. When this condition occurred, Anthony's visual acuity decreased from 20/20 to 20/70. About 8 months ago, Anthony received a corneal transplant in this eye. We refit Anthony's eye with a GVR Scleral lens which is now providing Anthony with clear (20/20) comfortable vision once again. In the first photo below, note the cloudy appearance in Anthony's cornea. This is how his left cornea appeared prior to corneal transplant surgery. The grey-white dagger shaped appearance in the center of the cornea is the torn membrane mentioned above. The last photo shows Anthony's transplanted cornea.

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
