Take-home: According to recent study results, transepithelial photorefractive keratectomy is a better alternative procedure than other refractive methods when treating myopia that involves epithelium mechanical manipulation.
Seoul, South Korea—Transepithelial photorefractive keratectomy (TransPRK) is a safe and effective alternative to other refractive procedures to treat myopia that involve mechanical manipulation of the epithelium, according to 12-month data from a South Korean prospective study.
This all-laser version of PRK showed similar visual and predictive results compared to LASEK and types of PRK that involve mechanical or alcohol-based removal of epithelium, however, it offered faster operative times, faster healing, less haze, and less postoperative pain than the more conventional and more invasive procedures.
“Transepithelial PRK with the Amaris laser platform is a modified no-touch, continuous single step technique for combined epithelial and stromal ablation,” said Jung Sub Kim, MD, B&VIIT Eye Center, Seoul, Korea. “The Amaris platform removes corneal epithelium with a modified PTK mode, which is different from other surface ablation refractive surgical techniques that use a brush, alcohol and other methods."
