WebBy removing the lenticule, the cornea’s shape is changed, thereby achieving the desired refractive correction. The laser procedure lasts for about 25 seconds and the extraction of the lenticule for another couple of minutes. The corneal cap thickness is of 120 microns, the residual stroma of 250 microns and the lenticule diameter is of 6,5 mm. WebWhen light, e.g. a laser beam, propagates from one transparent homogeneous medium into another, its propagation direction will generally change (see Figure 1).
