With Trans-PRK (also known as SmartSight), the correction is performed on the surface of the cornea under local anesthesia and after an eyelid retractor holds the eye open, without any contact or incisions. The epithelium (the cells of the corneal surface that are constantly regenerating) is also automatically removed with the laser. Previously, these were removed manually by the surgeon (PRK method).

At the end, antibiotic eye drops are applied and a contact lens, which remains on the cornea until the epithelium regenerates and is removed by the doctor after about 4 days, is put on. The contact lens reduces the expected pain.
