Evaluation of the Retinal Nerve Fiber Layer and Ganglion Cell Layer After Laser-Assisted in situ Keratomileusis, Femtosecond-Laser in-situ Keratomileusis, and Small Incision Lenticule Extraction Using Optical Coherence Tomography

All three procedures resulted in a transient increase in RNFL and GCL thicknesses. This increase was rapid, limited, transient, and reversible. It peaked for a week and returned to baseline by the end of this three-month study. At day one and day seven post-operatively, the Lasik group exhibited statistically significantly higher values than the Fs-Lasik and Fe-Smile groups.
