RGP fitting method for post-LASIK and irregular corneas
RGP fitting method for post-LASIK and irregular corneas
In 1996 I had PRK on both eyes. At the time, LASIK was not available
in Canada, and lasers did not have eye-tracking systems. In my left
eye, I ended up with a decentered ablation. In my right eye, I ended
up with a small ablation zone. The result was that I had severe
diplopia (double images) in the left eye and haloes and some ghosting
in the right. I suffered severe eyestrain and headaches for several
years.
Over the years I had two additional surgeries in my left eye (one was
wavefront, the other topographically-guided) and did get some
improvement. I've also tried almost every type of soft and RGP contact
available. A few years ago, I was fitted with WAVE RGPs, and wore them
off and on for two years, but because my left cornea was so irregular,
despite several attempts, I wasn't ever able to obtain a lens that
fitted properly and was comfortable.
Back in December, I was successfully fitted with semi-scleral lenses
by Dr. Gemoules in Dallas. At the time, he had just started working
with an optical coherence tomographer that allowed him to accurately
measure the cornea and sclera and use that data to manufacture custom
RGP lenses. For me, the comfort of the lenses has been excellent and
I've enjoyed a huge improvement in the quality of my vision.
I'm definitely not interested in having any more surgery, even if it's
wavefront or topographically-guided!
