RK Over Transplant Equals Constant Pain. Vision Clear and Comfortable with GVR Scleral Lens

The 3 images below are of the same eye. 20 years ago this eye underwent corneal transplant surgery. For many years this patient was unable to obtain functional vision with this eye due to a high degree of corneal distortion. 3 years ago, in an effort to make the corneal more spherical, her corneal surgeon decided to perform a modified RK surgery on the transplanted cornea. The result of this RK procedure was continuous pain along with a decrease in the patient's visual acuity. In the first image below, you can see the open RK incisions. A special green dye and filter were used to make this easier to see. In the 2nd photo, which is a profile view, you can see the open RK incision in the lower portion of the transplanted cornea. The 3rd image is a cross section of this cornea taken with a technology known as "Optical Coherence Tomography". The top 2 curved lines represent the front and back surfaces of the scleral lens. The thick curved grey structure below the scleral lens is the transplanted cornea. Look carefully to the left side of this image and you can see the open RK incision that extends half way through the cornea. With this scleral lens the patient is able to see clearly and comfortably for the first time in 20 years.

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
