Enhancement After Myopic Small Incision Lenticule Extraction (SMILE) Using Surface Ablation
CONCLUSIONS:</span><p>Combined with the intraoperative application of mitomycin C, surface ablation seems to be a safe and effective method of secondary enhancement after SMILE. Due to the usually low residual myopia, the ASA profile is not recommended in these cases.</p><p><b>[<i>J Refract Surg.</i> 2017;33(8):513 –518.]</b></p></div> (Source: Journal of Refractive Surgery)

The Effects of Distance Between the Corneal Apex and the Inner and Outer Corneal Wound Edges on Corneal Astigmatism After Cataract Surgery
CONCLUSIONS:</span><p>Corneal astigmatism was affected more by inner incision distance than outer incision distance, and a larger change in the posterior SIA was noted with decreasing inner incision distance. During cataract surgery, the position of the inner corneal incision should be considered rather than the outer incision.</p><p><b>[<i>J Refract Surg.</i> 2017;33(7):460 –468.]</b></p></div> (Source: Journal of Refractive Surgery)

Comparing the Zeiss Callisto Eye and the Alcon Verion Image Guided System Toric Lens Alignment Technologies
CONCLUSIONS:</span><p>The authors found that small deviations were frequent when comparing two sophisticated technologies. Although deviations greater than 3 ° occurred in less than 47% of captured images from 16 eyes, smaller but significant variations of less than 3° occurred in 53% of captured images from 16 eyes. It was rare to identify a large deviation. However, the authors identified “drift” in the same eye when measurements were taken at di fferent times. The results indicate that the two systems are not currently interchangeable. Superiority of one system over the other was not determined.</p&...

Integration of Scheimpflug-Based Corneal Tomography and Biomechanical Assessments for Enhancing Ectasia Detection
CONCLUSIONS:</span><p>The TBI generated by the RF/LOOCV provided greater accuracy for detecting ectasia than other techniques. The TBI was sensitive for detecting subclinical (fruste) ectasia among eyes with normal topography in very asymmetric patients. The TBI may also confirm unilateral ectasia, potentially characterizing the inherent ectasia susceptibility of the cornea, which should be the subject of future studies.</p><p><b>[<i>J Refract Surg.</i> 2017;33(7):434 –443.]</b></p></div> (Source: Journal of Refractive Surgery)

Refractive Changes Induced by Spherical Aberration in Laser Correction Procedures: An Adaptive Optics Study
CONCLUSIONS:</span><p>An inverse linear correlation exists between the refractive state of the eye and spherical aberration induced within the range of laser vision correction. Small values of spherical aberration do not worsen visual acuity or depth of focus, but positive spherical aberration may induce night myopia. In addition, the changes in spherical refraction when the pupil constricts may worsen near vision when positive spherical aberration is induced or improve it when spherical aberration is negative.</p><p><b>[<i>J Refract Surg.</i> 2017;33(7):470 –474.]</b></...

Contralateral Eye Comparison of SMILE and Flap-Based Corneal Refractive Surgery: Computational Analysis of Biomechanical Impact
CONCLUSIONS:</span><p>Intrastromal flapless procedures had less impact on anterior stromal collagen mechanics and resulted in lower stromal bed displacements and stresses than flap-based procedures in contralateral eyes. However, biomechanical impact varied widely between individuals and this reinforces the need for individualized assessment of ectasia risk.</p><p><b>[<i>J Refract Surg.</i> 2017;33(7):444 –453].</b></p></div> (Source: Journal of Refractive Surgery)

Biomechanical Changes After LASIK Flap Creation Combined With Rapid Cross-Linking Measured With Brillouin Microscopy
CONCLUSIONS:</span><p>LASIK flap creation significantly reduced Brillouin shift in the anterior third of the stroma in porcine eyes. Rapid corneal cross-linking had no significant effect on Brillouin shift after LASIK flap creation in porcine eyes. With further validation, non-contact, non-perturbative Brillouin microscopy could become a useful monitoring tool to evaluate the biomechanical impact of corneal refractive procedures and corneal cross-linking protocols.</p><p><b>[<i>J Refract Surg.</i> 2017;33(6):408 –414.]</b></p></div> (Source: Journal of Refractive Surgery)

A New Extended Depth of Focus Intraocular Lens Based on Spherical Aberration
