Longitudinal Evaluation of Posterior Corneal Elevation after Laser Refractive Surgery Using Swept-Source Optical Coherence Tomography

The findings of our study suggested that there was a mild but significant forward protrusion of the posterior cornea after femtosecond laser-assisted LASIK and PRK. The posterior cornea fluctuated during the first postoperative year after LASIK, whereas it stabilized as early as 3 months after PRK.
