RK followed by ALK

The 2 images below are of the same eye. This eye underwent Radial Keratotomy about 30 years ago followed by a form of LASIK surgery known as ALK (Automated Lamellar Keratoplasty). In the photo below a special dye (fluorescein) was instilled onto the ocular surface to highlight the defects and breaks on the cornea. The horizontal and oblique green lines are the open RK incisions. Look carefully and you can see a light green circular line going around the pupil. This is the outline of the ALK flap. ALK surgery is no longer being done in the U.S. The 2nd image was taken with a technology known as "Optical Coherence Tomography" or OCT. This image shows a scleral lens over this cornea. The thick curved grey structure is the cornea. Look carefully in the center of the cornea and you can see the outline of the ALK flap. This cornea is extremely dry and irregular. With a scleral lens this patient is able to see clearly and comfortably. In addition, the scleral lens protects the damaged cornea from the blinking action of the eyelids and the environment.

SMAP 3D Scleral Lens Design

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
