A Comparison of PRK and LASIK for Correction of Myopia

November 24, 2006 updated by: University of Aarhus

A Prospective, Randomised Trial of Photo-Refractive Keratectomy (PRK) and Laser-in-Situ-Keratomileusis (LASIK) for Correction of Myopia

The study compares the precision and accuracy of two laser refractive techniques, PRK and LASIK, for correction of nearsightedness between -6 and -8 diopters.
