Effect of 60 kHz and 150 kHz Femtosecond Lasers on Corneal Stromal Bed Surfaces: A Comparative Study
Figure 1
IntraLase FS laser reading site and cut site. The IntraLase FS laser measures the cut site from epithelium. Thus a standard depth of 400 μm was maintained both for anterior and posterior cuts. (a) Since the FS laser begins the cut from the endothelium, anterior lamellar graft was prepared by applying lamellar cut first followed by the vertical or side cut. The thickness was maintained at 400 μm from the anterior reading site. (b) In posterior lamellar graft the side cut is performed first followed by the lamellar cut. The thickness was maintained at 400 μm from the anterior reading site. The posterior lenticule retains its thickness in the range of μm depending on initial corneal thickness.
