Three Corneal Transplants in Three Years due to rejection

The 3 photos shown here were taken recently of the same eye. This eye underwent 3 corneal transplant surgeries over the past 3 years. The reason for 3 corneal transplants was rejection of the prior 2 transplanted corneas. The original underlying reason for these surgeries was keratoconus. The point of my showing these photos is to demonstrate the ripple effect of ocular surgeries.Corneal transplant surgery has also been done on many patients who developed post-LASIK corneal ectasia, which has a similar ocular presentation to keratoconus. For over 2 years this eye was subjected to topical steroid drops multiple times daily in order to prevent rejection of the transplanted corneas. As a result of the steroids, this eye developed glaucoma. The intra ocular pressure in this eye could not be lowered to a proper level to prevent damage to the internal ocular structures. As a result 2 glaucoma shunts were surgically implanted into this eye to allow the proper outflow of the intraocular fluid (aqueous). In the first photo you can see the corneal transplant. If you look carefully you can make out the faint shadows of the glaucoma shunts. In the 2nd and 3rd photos note the large bulbous areas on the white portions of this eye. These are due to the glaucoma shunts. This eye is being fit with a specialty scleral lens which will provide clear vision once again. For many years I have told patients to avoid all types of refractive surgeries. I have also told patients who did develop post-LASIK complications to avoid "enhancements" due to the risk of additional irreversible problems. I hope that these photos bring home this point.

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
