(Left) – Raw images of Figure 1. (Right) – The proposed image processing pipeline segments intrastromal lenticule and flap cuts by first enhancing the structures (a, b), then applying a segmentation algorithm to identify corneas (c, d) and consequently the domains of cuts (e, f). Panels in (e) illustrate the presence of sideband noise and its removal to achieve the correct flap geometry. Panel (f) demonstrates the optimization process for detecting the correct posterior (lenticule) cut (orange dots) using Algorithm 1.
