RK in 1995 now have fluctuation in vision

Postby debrany » Thu Mar 11, 2010 8:59 pm

I am one of the many individuals who had Radial Keratotomy (RK) in 1995 and I am now experiencing fluctuation in my vision quality throughout the day.
I would like to find a doctor in the NY/LI area who specializes in this issue. I need computer/reading glasses and have gone to a doctor but the lenses were too strong and hurt my eyes.
I have gone to specialist in NYC in 2007 that said there was nothing they could do but there was research being done.
Thanks,
Debra

Radial Keratotomy (RK) was a popular technique to reduce myopia (nearsighted, shortsighted) vision by making radial incisions through 90% of the cornea to cause a collapse of the corneal center, thereby reducing myopia. Many people who had RK with more than 8 incisions are experiencing vision fluctuation now that 10-20-30 years have passed. The fluctuation is primarily because the cornea has become too weak and fluctuating intraocular pressure (IOP) raises and lowers the height of the cornea.

Although laser vision correction can correct refractive error on a patient who had RK, it cannot stop the fluctuations. In fact, laser vision correction removes corneal tissue and can make matters worse.

A very promising procedure to stabilize a fluctuating RK cornea is Corneal Collagen Crosslinking (CxL). CxL is currently going through clinical trials and is not generally available in the US, however there are several providers in Canada. It may be valuable to research this emerging technology.

In the interim, Rigid Gas Permeable (RGP) contact lenses may provide the needed stability. It may also be appropriate to lower IOP.
