Laser confocal microscopy examination findings. Laser confocal microscopy examination showed that corneal epithelial cells was edematous, the boundary was not clear, and the connection was loose at post-operative month 6 (A). The boundary of the epithelial cells of cornea were clearly recovered (B), but the nerve fibers were still not found in the Bowman’s layer of cornea (C) at post-operative month 12. Nerve fiber and scar tissue can be found in the Bowman’s layer of cornea at post-operative month 24 (D).
