Photorefractive keratectomy (PRK) was first introduced to ophthalmology back in 1988, and it’s the laser refractive surgical technique that our field has the greatest clinical experience with.
In PRK, individual laser pulses reshape the cornea. Each laser pulse is about 0.2 µm in diameter (one five-thousandth of a millimetre) and 1000 of them can be produced in one second. This computer-controlled precision makes the eye surgeon a sculptor with the most precise “chisel” available: the excimer laser.

Today’s PRK is considerably more advanced than the PRK of a decade ago. Today, we can perform “Touchless” SmartSurface TransPRK – the eye is not touched at all. The laser incorporates “SmartPulse” technology, in which a precise 3D model of the cornea is generated and allows the laser to provide better, closer and more even spacing of laser pulses on the cornea, leaving a smoother cornea afterwards, resulting in faster healing times and visual recovery times far faster than with traditional PRK.
TransPRK non-invasive, gentle, stress-free and the result is clear vision.
The procedure is completely non-contact. The eye is not touched. No flap. No suction. No blades. No incisions. Just laser.
The laser treatment takes place entirely on the surface of the cornea. No incisions and no flaps mean no incision-related or flap-related complications.
The laser correction is performed in a single step – and, unlike femto-LASIK, with a single laser. This ensures a short treatment time and less stress for the patient.
Procedure explained
SmartSurf technology ensures a particularly smooth cornea – meaning a shorter healing process and a significantly faster increase in visual performance than patients experience with conventional treatments.
No flap plus SmartSurf smoothness means that tear film production of the tear film is hardly altered at all. That’s why SmartSurf is also ideal for patients with dry eyes or who have contact lens intolerance.
Compared with eyes treated with LASIK, those treated with non-invasive SCHWIND AMARIS Trans-PRK leaves patients with a stronger cornea, making it safer in the long-term for the patient.
