PRK

History of PRK

As mentioned earlier in this book, PRK was introduced in 1987 and was approved by the U.S. FDA in 1995. Instead of a microkeratome being used to create a corneal flap, with PRK the surgeon uses the laser to accurately sculpt the cornea one microscopic layer at a time. As awareness of LASIK grew, PRK became less popular, because of the increased comfort and more rapid recovery of vision that LASIK offered.

In the last decade, a newer generation of excimer lasers, along with refined techniques, have minimized the risks of PRK. And patients today have an easier recovery. As a result, PRK has become a viable option for a variety of patients whose needs are not met by LASIK.
