Yu M, et al. - Researchers assessed 32 subjects in the small incision lenticule extraction (SMILE) group and 32 cases in the laser-assisted subepithelial keratomileusis (LASEK) group to examine the outcomes of posterior corneal elevation and biomechanics after SMILE and LASEK for myopia. They observed a decline in corneal hysteresis (CH), corneal resistance factor (CRF), and intraocular pressure (IOP) with shifting backward of central posterior surface in both groups, 3 months postoperatively. They recorded a lesser impact of SMILE in terms of per unit corneal tissue removed on corneal biomechanics as compared to LASEK at an early stage post-operative. They also noticed flattened corneal back power (Kb) and shallower anterior chamber depth (ACD) in both groups.
