Trans Epithelium

 

 With the SCHWIND AMARIS laser systems it is possible to carry out no-touch, all-laser surface ablations. The so-called TransPRK (Trans epithelial Photorefractive Keratectomy) is an advanced version of surface treatments as LASEK, Epi-LASIK and PRK. Thereby the epithelium, which is the regenerative surface of the eye, is ablated by the laser system. The TransPRK is a Transepithelial single-step treatment that avoids the eye coming into contact with any instrument.

TransPRK applies an epithelial thickness profile that is thinner in the centre than in the periphery. Because TransPRK applies the laser beam directly over the epithelium, it acts as a smoothing agent for the residual stromal bed
