Radial Keratotomy in 1998, Lasik in 2002, Followed by Ectasia, has Six Years Good Vision with GVR Scleral Lens

This patient underwent Radial Keratotomy (R-K) surgery in both eyes in 1988. Several years later her vision began to deteriorate and in the following years was not able to obtain satisfactory vision with either eyeglasses or contact lenses. In 2002, she visited another corneal surgeon who encouraged her to undergo LASIK surgery to correct her distorted corneas created by the R-K surgery. Shortly afterwards, a condition known as post-LASIK corneal ectasia took place. This condition is a risk factor in patients who have undergone LASIK surgery, however, the risk of this developing is much greater in patients who have undergone prior refractive surgeries such as R-K. Corneal Ectasia involves a protrusion of the front surface of the eye (the cornea). This patient's cornea was not only extremely distorted, she also suffered from chronic dry eyes and ocular pain. Due to the significant pain she had been experiencing and her inability to obtain functional vision with eyeglasses, this patient visited our office 6 years ago seeking help. 6 years ago we fit this patient with GVR Scleral lenses which have provided her with clear, stable vision. Today, this patient came in for her yearly comprehensive eye and lens evaluation. Both of her corneas have remained stable and she is seeing clearly and comfortably with all day lens wear. Below the photo of this patient with me can be seen photos of her right and left eye with her Scleral lenses over her scarred corneas. If you look carefully you can see the R-K incisions. Next to these photos is a photo of her right cornea without a lens in place. A dye was instilled onto the front surface of her eye to demonstrate the open R-K incisions along with the LASIK flap. The straight lines in the cornea are the R-K incisions which still remain open after all these years. One can tell they are open because the dye can be seen within the corneal incisions. The round circular line going around the periphery of the cornea is the LASIK flap incision. This patient will need to be seen at least once each year to make certain that infection does not occur and that her corneas remain clear and stable.

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
