Lasik over RK, then Cystalline Keratopathy

The 2 images below are of the same eye that underwent both Radial Keratotomy and LASIK surgery. I have been taking care of this patient for over 10 years. 2 years ago this opacity appeared in the center of one eye. I referred this patient to a major eye institution where a diagnosis of "Crystalline Keratopathy" was made. This condition is a very rare LASIK complication. This patient was prescribed fortified antibiotics to use over a year. Over the past year this opacity has become more pronounced. This week this patient visited a corneal specialist at another world class eye facility where a recommendation of removal the LASIK flap was recommended. The purpose of this procedure is to culture the tissue to determine what organism (bacteria, fungus etc.) has caused this opacity to occur. Today this patient and I went back and forth texting each other. She told me that this lesion was thickening and the visual haze was more severe. She also wrote " if left untreated it can literally explode in bacteria creating a much worse condition...." " ultimately I will likely need a corneal transplant". she continued " I am at the end of my rope". The first photo was taken 2 years ago. You can see that the opacity is in the line of vision. The 2nd image was taken with a technology known as "optical coherence tomography". This image was also taken 2 years ago. The curved thick grey structure is the cornea. The white streak going through the center of the cornea are the crystalline formations.

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
