PRK, then Ectasia

This is the right and left eye of a patient that underwent photo refractive keratotomy (PRK) surgery about 8 years ago. Several years later the patient's vision began to deteriorate. When he visited another corneal surgeon, a diagnosis of Corneal Ectasia was made. In an effort to improve his vision, this patient underwent Intacs surgery in both eyes. Intacs are plastic rings that are inserted into the cornea in an effort to make the cornea more spherical. These 2 surgeries resulted in 2 severely distorted corneas. We recently fit this patients eyes with scleral lenses. In these photos, a special dye was used to highlight the defects in the cornea. The "horseshoe" shaped structures are the plastic rings that were surgically inserted into the corneas. Note the green spots concentrated over these plastic rings. These represent dry areas along the corneal surface. I feel that this patient's scleral lenses will create a corneal surface that will have a healthier and more moist appearance.

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
