Chung B, Kang DSY, Arba-Mosquera S, et al. - In the present study, the researchers sought to explain the surgical outcomes following transepithelial photorefractive keratectomy (PRK) for a case of retained intrastromal lenticule fragment after small incision lenticule extraction (SMILE). Transepithelial PRK was conducted to reduce corneal irregularity and to correct residual refractive errors in a patient who had undergone failed lenticule extraction, resulting in a refractive lenticule fragment being retained for 14 months after primary SMILE. According to results, corneal higher order aberrations, including coma, trefoil, and spherical aberration, were significantly reduced. After primary SMILE, transepithelial PRK is a possible alternative for managing a retained lenticule fragment.
