Two eyes - RK and Lasik

The 2 photos below are of eyes that underwent refractive surgeries. The eye in the first photo underwent Radial Keratotomy (RK) eye surgery over 30 years ago followed by LASIK about 15 years later. Several years after the LASIK this patient lost vision suddenly. Post-LASIK ectasia was the cause of the vision loss. Shortly after the ectasia was diagnosed, this eye developed a condition known as "hydrops". This is a condition where the most posterior corneal membrane ruptures allowing fluid from within the eye to enter the cornea creating a scarred appearance. In this photo, the white oval scar that you see is the result of the "hydrops". Also note the numerous blood vessels that have spread throughout the cornea. A healthy cornea is devoid of all blood vessels. This eye was fit with a scleral lens (seen in this photo) which has provided a significant amount of vision improvement. The 2nd photo seen below is of an eye that underwent Radial Keratotomy (RK) many years ago. About 20 years after undergoing this surgery, this patient's cornea became infected and inflamed and needed to be replaced with a new cornea. The end result was a total of 4 corneal transplant surgeries that were done on this eye. This is a photo of the 4th transplanted cornea which is failing and will need to be replaced. There is no functional vision in this eye.

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
