Figure 4

In vivo confocal microscopy evaluation at 4 days and 4 weeks postoperatively at the planes anterior (A) and posterior (B) to the lenticule plane (SMILE and SMILE-W groups) or flap interface (LASIK group). Activated keratocytes with high intensity of reflectivity were seen at day 4 in the post-SMILE and post-LASIK eyes for both refractive corrections. At week 4, the keratocyte nuclei became more quiescent.
