Management of Laser Settings for Better SMILE Surgery
As a physiological principle, single gas bubbles join to form fewer, but bigger gas bubbles if they are close enough. These big bubbles are deforming the surrounding tissue. Consequently the…
SMILE for Correction of Very High Myopia (Higher than −10 D)
Fig. 18.1 (a) Preoperative Pentacam image of an eye with the manifest refraction of −12.0 −1.0 @ 165°. (b) Same eye 1 week postoperatively. The manifest refraction (MR) is +0.25…

Brief Historical Overview of the Clinical Development of ReLEx® Surgical Procedure
Fig. 4.1 The treatment pack During this period of time in 2005, a series of studies by Blum and Sekundo (unpublished data) on animals, blind and amblyopic eyes, underwent a…
Refining Results with SMILE: Tips and Tricks

Femtosecond Laser Keratomes for Small Incision Lenticule Extraction (SMILE)
Fig. 1.1 Contour deviation and roughness are useful parameters for characterizing a cut surface. They measure deviations of the intended shape with very low and very high spatial frequency. Deviations…
