Lasik Over RK Articles

Two RKs, Then Four Lasiks, then Ectasia, Neovascularization, and Epithelial Ingrowth.

The eyes seen here underwent 2 separate Radial Keratotomy surgeries in the 1980's. Beginning in 2000 and for several years after, each eye underwent 4 separate LASIK surgeries. Both eyes developed ectasia following these surgeries. In addition, over a period of years, both corneas became neo-vascularized (blood vessel growth onto the cornea) and developed epithelial ingrowth. Epithelial ingrowth is a condition where the cells from the outermost corneal layer (the epithelium) begins to grow under the LASIK flap where it does not belong creating a cloudy cornea. Look carefully at the first photo and you can see at 11:00 and 12:00 a cloudy inflamed appearance within the open RK incisions. These are epithelial cells that have gotten into the central cornea through the open RK incisions. In the 2nd photo, notice the grey haze opposite the pupil. This is epithelial ingrowth. Epithelial cells have gotten under the LASIK flap and are growing in an area where they do not belong. Note the blood vessels growing onto the cornea from 9:00 and 10:00. Again, blood vessels do not belong on the cornea. At the present time this patient has an appointment with a corneal specialist to determine if a corneal transplant in the left eye is the most appropriate course of action.

Epithelial Ingrowth After RK and Lasik Surgery

The top photo was taken in 2010. Note the blood vessels growing along the RK incision. In addition, if you look carefully you will notice a few milky-white deposits near the blood vessels close to the pupil. This was the first sign of epithelial cells ( the outer cellular layer of the cornea) getting underneath the LASIK flap. The lower photo was taken in 2013. Note how the milky white area has grown dramatically. The R-K surgery was done in 1988 and the LASIK surgery was done in 1999. At the present time this patient is having a consultation at a major university eye center for a corneal transplant.

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
