RK about 15 years ago, then Lasik, Open Incisions

The images below are of the same eye. This eye underwent Radial Keratotomy (RK) 30 years ago. 15 years later this same eye underwent LASIK surgery. A special dye was used to highlight the corneal defects created by these surgeries. In the first photo, note the lite up radial lines. These are the still open RK cuts or incisions. Note the circular yellow green line going around the periphery of the cornea. This is the border of the LASIK flap. The bright green horizontal line going across the lower portion of the cornea is known as a "cross cut incision" intended to eliminate any astigmatic error. The fact that these defects "lite up" tell you that these incisions are still open and subject to infection from opportunistic organisms entering these defects. The 2nd image was taken with a computerized corneal topographer. This technology involves casting lit concentric rings at the cornea. These rings reflect back into the computer-camera so that a photo can be taken. If the cornea had a smooth undistorted surface, the rings would appear to be perfectly round. Note how distorted these rings are. It is for this reason that eyeglasses and regular contact lenses cannot correct the vision in this eye. A scleral lens, however, will replace this cornea as an optical surface and allow the patient to see clearly once again.

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
