Abstract

PURPOSE: To longitudinally compare the visual and refractive outcomes and changes in corneal thickness between femtosecond-assisted sub-Bowmen keratomileusis (SBK) and photorefractive keratectomy (PRK) with mitomycin C in eyes with high myopia. METHODS: Patients with spherical equivalent ≥6 dioptres (D) who underwent femtosecond-assisted SBK or PRK with mitomycin C were recruited. All patients were examined preoperatively and after 1 week, and, 1, 3, 6 and 12 months postoperatively. Assessments included uncorrected and best-corrected distance visual acuity , and manifest refraction spherical equivalent. Corneal thickness was measured using swept source optical coherence tomography. RESULTS: ..
