Intacs and X-Linking Patient Now 20/20 in Each Eye with GVR Scleral Lens

This patient has very advanced keratoconus in both eyes. 4 years ago he visited us from Mexico seeking a solution to his vision loss and to avoid a scheduled corneal transplant operation. When he first came into our office his corrected visual acuity with his eyeglasses was very poor. He had been unable to see clearly with any type of contact lenses. The gas permeable lenses given to him were very uncomfortable and unstable and would often pop out of his eyes. We fit this patient with GVR Scleral lenses which provided him with clear (20/20 in each eye) and comfortable vision with all day lens wear. Over 2 years ago, this patient visited another doctor for Intacs surgery and Collagen Cross-linking therapy. He was under the impression that these 2 procedures would "cure" his keratoconus and eliminate his need to wear the scleral lenses we provided him. Last month this patient returned to our office for a comprehensive eye and lens evaluation. Both of his corneas were clear and healthy. The shape and contour of his corneas were essentially the same as they were 4 years ago as was the status of his keratoconus. The GVR scleral lens design was changed slightly and dispensed to him last week. With his new lenses this patient is still seeing clearly and comfortably. Next to the photo of me and this patient, I posted a photo of the scleral lens over his cornea with the Intacs. Note the "horse-shoe" shape structure just below the pupil. This is a plastic ring (Intacs) that was surgically inserted into the center of the cornea. Both of his corneas look the same. The principle behind this technology is to make the distorted cornea smoother and less irregular. Unfortunately, Intacs does not provide the same therapeutic benefit to every patient. As long as this patient wears his GVR Scleral lenses he will never need to undergo corneal transplant surgery.

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
