Trans-PRK Lasersoft no-touch

TRANS-PRK (T-PRK) with the LASERSOFT NO-TOUCH TECHNIQUE

Standard PRK has been performed since 1992. With that technique the surface membrane of the cornea, the epithelium, is removed mechanically with either a brush or a blade, with or without alcohol to soften the epithelium beforehand. After epithelial removal, the laser is applied to the underlying corneal surface and a bandage contact lens is applied to the eye to prevent the lid from rubbing on the cornea. The epithelium heals in about 7 days and the contact lens is removed.

TRANS-PRK (T-PRK) with the Schwind Amaris laser is a revolutionary new procedure that is a no-touch technique. The only excimer laser on the market that can perform T-PRK is Laservue’s Schwind Amaris laser with its unique SmartSurface software. In this procedure, no flap is created as with lasik. The laser is applied directly to the surface of the eye and lasts anywhere between 20 and 40 seconds depending on your prescription. It removes the epithelium and does the refractive correction all in one laser application. No instrument touches the eye. The Schwind software creates an extremely smooth surface on the cornea because of its proprietary SmartPulse pattern of finely spaced pulses on the cornea

At Laservue we have perfected this technique and call it the LaserSoftTM no-touch technique. The advantages of the LaserSoftTM no-touch technique are twofold: much faster healing of the corneal surface (3 days as opposed to 7 days with standard PRK), and greatly enhanced laser precision and more accurate results.

T-PRK with Laservue’s
LaserSoftTM no-touch technique gives equivalent results to lasik, but the visual recovery is slightly longer. Some patients prefer surgery where no instrument touches the eye, and T-PRK is perfectly indicated for these people. In some rare cases (thin or irregular corneas) T-PRK is preferred over lasik because of the absence of a flap.
