PRK and TransPRK are similar to LASIK in that they use laser energy to reshape the cornea to treat refractive errors permanently.
PRK vs LASIK
One key difference is that LASIK involves the creation of a corneal flap, and PRK does not. With traditional PRK, an excimer laser is used to carefully reshape the cornea tissue and its curvature.
At VSON, we go one step further again with TransPRK (transepithelial photorefractive keratectomy) by SCHWIND.
Unlike with conventional surface laser methods like LASEK, Epi-LASIK and PRK, with TransPRK the eye is not touched with any instrument.
Instead, the SCHWIND AMARIS laser removes the epithelium (the outer layer of the cornea), without suction, flap, or blade, and without the use of blunt alcohol. This touch-free procedure is non-invasive, safe, and gentle to the eye. Discover more about TransPRK here.
