ALK Complications addressed with GVR Scleral Lens

This patient (in center of photo) underwent a refractive surgical procedure known as Automated Lamellar Keratoplasty or ALK. The purpose of this surgery was to eliminate this patient's hyperopia (far sightedness) and astigmatism. For 8 years this patient was satisfied with his post-surgical vision. After 8 years during a 3 week period his vision deteriorated to the point where eyeglasses and contact lenses were unable to provide functional vision. For several years this patient visited a number of doctors who told him that his only option was to have corneal transplant surgery. 3 years ago we fit this patient with GVR Scleral lenses. With these lenses he is able to see clearly (20/20) and comfortably with all day lens wear. In the photo with the cornea immersed in dye you can see the outline of the ALK cornea flap. The lower photo to the right shows a cross section of the post-surgical cornea with the GVR Scleral lens over it. The scarring from the ALK surgery is visible in the center of the cornea. With the GVR Scleral lens, this patient will never need corneal transplant surgery. By the way, the young lady to the right is our student extern (soon to be eye doctor) Tina Cheung.

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
