Lasik over RK with haze and dryness

The images below are of the same eye. In the 1980's this eye underwent 3 separate Radial Keratotomy (RK) procedures followed by 2 separate LASIK procedures about 25 years later. The photo below was taken through a bio-microscope (slit lamp). Notice the dull grey spike like figures going from the corneal periphery towards the center. These are the open, scarred RK incisions. Again, look carefully and you will see a dull, grey "smile-like" image in the lower portion of this photo. This is "epithelial ingrowth". This is due to the cells on the surface of the cornea (epithelial cells) getting under the LASIK flap where they do not belong. It is quite possible for these cells to proliferate years later below the LASIK flap leading to vision loss. The 2nd image was taken with a technology known at "Optical Coherence Tomography" or "OCT". This is a cross section of the cornea with a scleral lens over it. The top 2 curved lines represent the front and back surfaces of the scleral lens. The thick grey curved structure is the cornea. Look carefully and you can see a curved white haze in the center of the cornea toward the right side of the image. This is another view of the epithelial ingrowth. This patient will have to be seen at regular intervals to make sure that the cornea remains stable. This cornea is extremely irregular and has a very dry ocular surface. The scleral lens is the only technology that will allow this patient to see clearly and comfortably with this eye.

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
