The Percent Volume Altered in Correction of Myopia and Myopic Astigmatism With PRK, LASIK, and SMILE. Gatinel D, Weyhausen A, Bischoff M. Journal of Refractive Surgery. 2020;36(12):844-850
In this study, we compare the volumes of tissue removed and Percent of Volume Altered (PVA) values of different treatment modalities: photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), and small incision lenticule extraction (SMILE) for the correction of myopia and myopic astigmatism. This may give clinicians an improved understanding of the potential influence of geometrical parameters of those methods on the biomechanics of the cornea.
