This retrospective study was designed to evaluate the efficacy and safety of simultaneous topography-guided PRK plus cross linking for patients with mild to moderate keratoconus and to evaluate the stability of the cone. The patients were evaluated over two years for the progression and stability of the cone by the Allegro Pentacam Oculyzer to assess the changes of corneal curvatures (K readings) and the stability of the cone after the surgery and evaluating uncorrected distance (UDVA) and best corrected (CDVA) visual acuities. The follow-up results showed that UDVA improved from 0.4±0.3 to 0.7±0.1 and CDVA changed from 0.6±0.1 to 0.8±0.1 (P < 0.001). The keratometry value decreased from 44.1±2.2 to 41.4±1.6 D for K1, and from 46.4±2.6 to 43.5±1.7 for K2 (P < 0.001). This combined procedure offers a promising method to stabilize the corneal surface with reducing higher order aberrations so enhancing quality of vision in keratoconus patients.
