Lee MD, Chen LY, Tran EM, et al. - Researchers conducted this prospective study to compare the results of retreatment with wavefront-guided LASIK vs wavefront-guided PRK for residual refractive error following previous myopic keratorefractive surgery. After prior myopic keratorefractive surgery, 32 eyes of 28 patients underwent retreatment with flap-lift wavefront-guided LASIK (n = 12) or wavefront-guided PRK (n = 20) for residual refractive error. Following previous keratorefractive surgery, wavefront-guided LASIK and wavefront-guided PRK show comparable safety, efficacy, and predictability with comparable wavefront outcomes.
