a, b: One suture can be seen under the inferonasal margin of the pupil without loosening (which was repaired at local hospital). The cornea was edematous with fluid accumulation in the lamellar interface in the eye (yellow arrows). c: AS-OCT showed the wound was not completely healed and communicated with the interface fluid accumulation (green arrows), the cornea had diffuse microcystic epithelial edema (blue arrow), a hyporreflection space between the cornea flap and the stromal bed was present (red arrow). d, e: Two hours postoperatively, corneal edema subsided significantly, microcystic epithelial edema and lamellar interface fluid disappear, the perforation was in good alignment. f: AS-OCT showed that the corneal stroma was still edema but there was no significant interface fluid. g, h: One month postoperatively, the cornea was transparent, the tissue infiltration and edema at the perforation port were further limited, the corneal surface was regular. i: The wound healed well and the corneal edema subsided, leaving an area of hyperreflection
