Radial Keratotomy Corrected to 20/100 with Glasses, now 20/20 with GVR Scleral Lens

This is a photo of me with my patient Ricardo, who has been visiting our practice from Guatemala for the past 10 years on a yearly basis for his annual eye examinations. About 30 years ago, Ricardo underwent Radial Keratotomy surgery in both eyes. While his vision at first was quite good for the first few years, his vision gradually started to deteriorate. When I first met Ricardo, he was wearing eyeglasses which were providing him with 20/100 vision with a lot of visual distortions. He tried to wear various contact lens designs which were either uncomfortable or were unable to provide him with functional vision. 10 years ago, we fit Ricardo with GVR Scleral lenses. With these lenses Ricardo has clear (20/20) vision both at distance and close up and is able wear his lenses all day comfortably. Over the past 10 years we have only had to make a few changes to his scleral lenses. The 2nd photo seen below shows a close up view of Ricardo's open RK incisions. Note the blood vessel growth along the incisions. The last image was taken with a technology known as "Optical Coherence Tomography" or OCT. In this image the top 2 curves lines represent the front and back surfaces of the scleral lens. The large grey structure going left to right is the cornea. Note the wide, open break in the cornea on the right side of the image. This is an open RK incision that will never heal. Ricardo's scleral lens protects this eye from the blinking action of the eyelids and from the environment. In addition, because of the liquid reservoir between the back surface of the lens and the front surface of the cornea, Ricardo's eye is always in a moist environment. I expect Ricardo to be able to wear his scleral lenses for many years with excellent comfort and vision.

The Wavefront Scleral Lens

The corneal irregularities created by refractive surgeries, such as LASIK and RK, are responsible for ghosting, halos, starbursting, and loss of contrast sensitivity. These "higher order aberrations" may exist on both the anterior and posterior. With aberrometry, the defects of the entire optical system can now be corrected by a scleral lens.

Autologous Serum for Dry Eyes

Dry eye conditions are among the most challenging conditions faced by refractive surgery patients. With autologous serum, blood is spun down to plasma, forming an eye drop that helps rehabilitate the cornea.

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
