Lasik, then Ectasia, then PRK, then Haze

The 2 images below are of the same eye. This patient's eye underwent LASIK surgery 5 years ago. Several years later this eye developed post-LASIK corneal ectasia. After this diagnosis was made, it was suggested that this patient undergo PRK (photo refractive keratectomy) surgery to make this cornea more spherical. The first photo shows this cornea after the LASIK-PRK surgeries were done. Look carefully and note the circular line at 6:00 and 5:00 o'clock. This is the seam of the LASIK flap. Note the cloudy areas below the pupil. This is the corneal haze created by the PRK surgery. The 2nd image is a 3-D computer enhanced model of this cornea showing the extreme corneal distortion. If this was a "normal" cornea, the front corneal curve would be smooth and spherical. This patient is wearing a scleral lens over this eye which is allowing him to see clearly (20/25) without distortions. The bottom line is that the PRK surgery created additional problems for this patient. In my opinion, he would have been better off not getting involved with any additional procedures.

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
