What is Transepithelial PRK?

Reviewed by Jung Sub Kim, MD.

Similarly, you may ask, what is TransPRK?

TransPRK is a laser vision correction that is safe and minimally-invasive as it is surface-based.

Furthermore, which is better Lasik or PRK eye surgery? The difference is that #LASIK reshapes your cornea underneath a flap (think of the flap as being like a trap door on your cornea) whereas #PRK reshapes your eye on the surface. LASIK offers the advantage of quicker healing. Most patients with LASIK have excellent vision the day after surgery.

Similarly, you may ask, is PRK more expensive than Lasik?

It is very similar to LASIK, although PRK was developed before LASIK was approved. Because this process is older and less time-consuming, PRK is typically less expensive than LASIK; however, it can still be costly because insurance is not likely to cover it.

The Success Rates of PRK Surgery

PRK is highly successful at treating refractive errors, which you may know better as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Studies of PRK patients have found that 70 percent achieve 20/20 vision or better; 92 percent will achieve 20/40 vision or better.

Is PRK permanent?

PRK remains a common option for laser eye surgery. PRK and LASIK both permanently reshape the cornea to improve vision by using a laser (an excimer laser to be exact) to remove part of the tissue underneath the corneal epithelium.

Does PRK surgery hurt?
