Small Incision Lenticule Extraction (SMILE) for Hyperopia: Optical Zone Diameter and Spherical Aberration Induction
CONCLUSIONS:</span><p>The mean achieved optical zone diameter of hyperopic SMILE was found to be larger than the mean achieved optical zone diameter of hyperopic LASIK. Consequently, spherical aberration induction was similar for 6.37-mm SMILE and 7-mm LASIK.</p><p><b>[<i>J Refract Surg.</i> 2017;33(6):370 –376.]</b></p></div> (Source: Journal of Refractive Surgery)

Comparative Analysis of the Clinical Outcomes of SMILE and Wavefront-Guided LASIK in Low and Moderate Myopia
CONCLUSIONS:</span><p>SMILE and WFG LASIK are efficacious and safe procedures for the correction of low and moderate myopia, but WFG LASIK allows a more predictable outcome and better aberrometric control.<b>[<i>J Refract Surg.</i> 2017;33(5):298 –304.]</b></p></div> (Source: Journal of Refractive Surgery)

Regeneration of Defective Epithelial Basement Membrane and Restoration of Corneal Transparency After Photorefractive Keratectomy
CONCLUSIONS:</span><p>In the rabbit model, spontaneous resolution of corneal fibrosis (haze) after high correction PRK is triggered by regeneration of EBM with normal ultrastructure in the excimer laser-ablated zone. Conversely, incisional wounds heal in rabbit corneas without the development of myofibroblasts because the EBM regenerates normally by 1 month after surgery.</p><p><b>[<i>J Refract Surg.</i> 2017:33(5):337 –346.]</b></p></div> (Source: Journal of Refractive Surgery)

Topography-Guided LASIK Versus Small Incision Lenticule Extraction (SMILE) for Myopia and Myopic Astigmatism: A Randomized, Prospective, Contralateral Eye Study
CONCLUSIONS:</span><p>Topography-guided LASIK was superior in all visual performance parameters studied, both subjective and objective. The main difference between the two techniques likely derives from the eye tracking, cyclorotation compensation, and active centration control in the LASIK technology studied in contrast to the current technology available with SMILE-like procedures. This difference appears to affect refractive and visual aberration performance outcomes.</p><p><b>[<i>J Refract Surg.</i> 2017;33(5):306 –312.]</b></p></div> (Source: Journal of Refractive Surgery)

CONCLUSIONS:</span><p>Interface fluid syndrome can develop many years after LASIK as a result of corneal endothelial decompensation and can be effectively treated with DMEK.
