Cross-sectional Study on Corneal Denervation in Contralateral Eyes Following SMILE Versus LASIK.

Purpose: To compare long-term corneal nerve status following small incision lenticule extraction (SMILE) versus laser in situ keratomileusis (LASIK).

Methods: Twenty-four patients were randomized to receive SMILE in one eye and LASIK in the other eye. In vivo confocal microscopy examination and dry eye assessments were performed at a mean of 4.
