Lasik in 2000 and 2003. Emergency Corneal Transplant due to Intacs, now 20/25 with GVR Scleral Lens

These are photos of the right and left eye of a patient that underwent LASIK surgery in 2000 and once again in 2003 in each eye. Shortly after the 2nd LASIK procedure, this patient developed ectasia in her left eye. Her corneal surgeon attempted to insert Intacs (corneal rings) into her left cornea intending to smooth out the corneal surface. During the Intacs surgery the cornea got damaged forcing this patient to undergo an emergency corneal transplant. About 8 years later ectasia developed in this patient's right eye. A different corneal surgeon in Central America suggested that Ferrara Rings be inserted in her right cornea. Ferrara rings are very similar to Intacs except that they do not have FDA approval in the United States. In addition, the separation of the Ferrara rings within the cornea is much closer than seen with Intacs and can interfere with night vision. Look carefully at the first photo. This shows the right cornea with the Ferrara rings. Note that these rings are along the pupillary border and are affecting this patient's night vision. The 2nd photo shows this patient's left cornea with the transplant. The white-gray ring circling the peripheral cornea is the junction between the host and donor cornea. Look carefully and you can see new blood vessel growth onto the donor cornea at 12:00 and 1:00. Rarely do these blood vessels traverse the host-donor interface. This condition will have to be monitored indefinitely This patient had not been able to tolerate any form of contact lens correction. In addition, eyeglasses did not provide her with functional vision. For the past 2 years this patient has been wearing scleral lenses which are allowing her to see clearly (20/25) in each eye with excellent comfort.

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
