Patient Diagnosed with Keratoconus 60 Years Ago Receives GVR Scleral Lens

This is a photo of me with Guillermo, who suffers from an advanced case of keratoconus in both eyes but with a left eye with an extremely steep and thinned out cornea. Guillermo was diagnosed with keratoconus over 60 years ago. Over these many years he was fit with many different types of hard and soft contact lenses, "piggy back" lenses and hybrid lens designs both in this country and elsewhere. For 50 years, Guillermo suffered from discomfort, often pain, along with blurred vision with all of these lenses. About 10 years ago, we fit Guillermo with GVR Scleral lenses which have allowed him to see clearly (20/25 with his right eye and 20/40 with his left eye) and comfortably with all day lens wear. For the past 10 years, Guillermo's vision and eyes have remained stable. The first image below our photograph was taken with a technology known as "Optical Coherence Tomography" or simply "OCT". In this OCT image, the top 2 curved lines are the front and back surfaces of the scleral lens. The space between the back surface of the lens and the front surface of the cornea is filled with saline solution. The large curved gray structure is the keratoconic cornea. Note how steep the cornea is and how thin it is at the apex. A "normal" cornea is about 550 microns think. This cornea at the apex is about 120 microns thick. Prior to visiting our office, for about 40 years, Guillermo visited 7 world famous eye institutions seeking treatment for his eyes and vision. All of the doctors at these institutions suggested that he receive a corneal transplant on this eye. The last image is a profile photo of Guillermo's left cornea. Because this cornea is so steep, the center of gravity is too far out for this eye to support a conventional gas permeable lens. A scleral lens is the only lens technology that will allow a patient with an eye like Guillermo's to function with clear and comfortable vision once again. This technology is explained at: www.sclerallens.com.

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
