ALK on Hyperopic Cornea

The 3 images below are of the same eye. This eye underwent a refractive surgical procedure known as Automated Lamellar Keratoplasty or ALK. This procedure was abandoned about 15 years ago and as far as I know is not being done any longer. This eye was about +4.00 of hyperopia before the surgery. In order the improve this patient's distance vision this surgery created a cornea that looked like a keratoconic cornea or a cornea with post-LASIK ectasia. It was thought that by doing this the light rays would focus directly onto the retina without the need for spectacles. This did not happen. This surgery is done in a similar manner to LASIK except that the treatment zone is small and in the central area of the cornea. In the first photo, note the grey rings around the periphery of the pupil. This is the edge of treatment zone. The 2nd photo was taken after a special dye was instilled onto the ocular surface. In this photo you can see the small elevated treatment zone. The last image was taken with a technology known as "optical coherence tomography" or "OCT". This is a cross sectional image of this patient's cornea. Note the cuts created by the laser. After this patient underwent this needless, harmful surgery, the best corrected visual acuity in this eye was less than 20/200. He is now wearing a scleral lens on this eye which is providing him with 20/30 corrected vision without distortions.

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
