In 60 to 70 percent of cases it will actually begin to flat the cornea. In some cases immediately and in others it will take as long as a year.
The sad thing is it can stabilize for months if not years, and in a matter of weeks change drastically. (what happened to me)
You have had lasik and now have Keratoconus?
Feel free to give me a call and I can give you all the info ya need.
