OCT of Cornea

This is a cross-sectional OCT (Optical Coherence Tomography) image of a scleral lens over a cornea with "Hydrops" that underwent 4 separate LASIK procedures followed by a PRK procedure. These surgeries ultimately led to the destruction of the LASIK flap. In this image, the top 2 curved lines represent the front and back surfaces of the scleral lens. The thick curved gray structure is the cornea. Look carefully at the torn membrane on the left aspect of the back corneal surface. This membrane torn due to the pressures and forces within the eye against the weakened cornea. When this membrane tore, fluid from within the eye (aqueous) entered the cornea causing it to become cloudy. This entire scenario is called "Hydrops". Look carefully at the very top of this image. Note the curved gray white line along the corneal surface. This is the area where the LASIK flap once existed. What you see now is a form of scar tissue. This cornea is extremely distorted and dry. In addition, the ocular damage caused by these surgeries has made this eye very painful for this patient. This scleral lens has not only provided clear vision to this eye, but has also created an ocular environment where the eye is now moist and free of virtually all pain. Without the scleral lens this patient has less than 20/800 vision with this eye. With the scleral lens the patient is now able to see 20/30 with all day lens wear.

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
