Keratomileusis by Barraquer, Followed by RK

These 2 photos were taken of the same right cornea but with different optical systems. In the early 1970's this eye underwent a refractive surgical procedure known as "Keratomileusis". This refractive surgery was the "grandfather" of all refractive surgeries and was developed by Dr. Jose Barraquer in the 1960's. Keratomileusis is a surgical procedure in which a slice of the patient's cornea is removed, frozen and reshaped on a lathe and then sutured back on the remaining cornea to correct the refractive error of the eye. Dr. Barraquer was the only doctor in the world to do this procedure and when he passed away many years ago, this surgery ceased to be done. Note the circular outline going around the inner portion of the cornea. This represents the portion of the cornea that was removed, reshaped and sutured back onto the underlying corneal tissue. About 15 years later, this same eye underwent Radial Keratotomy (RK) surgery. Note the 8 horizontal and vertical incisions extending from the periphery of the cornea onto the central cornea. Needless to say, the vision in this eye has been severely reduced for over 40 years. This eye was fit with a scleral lens which is allowing this patient to see clearly and comfortably once again after all these 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
