title: [Corneal epithelium implantation under corneal flap after excimer laser in situ keratomileusis: a clinical pathological and cytological study and management].
abstract: OBJECTIVE
  To study the clinical pathological and cytological characteristics of corneal epithelial cells implanted under the cap of laser in situ keratomileusis and the method of management.
  
  
  METHODS
  For 4 eyes with epithelial cell implantation, the corneal cap was torn from temporal side to nasal, and the implanted material was removed from the flap and the stromal base. After washing between the interface, the cap was repositioned.
  
  
  RESULTS
  No epithelial implantation occurred again in these 4 cases after follow-up for 1 similar 12 months. The clinical pathological and cytological studies showed the material removed was degenerated and necrotic epithelial cells mixed with some unknown materials.
  
  
  CONCLUSIONS
  Clinically, the material formed under the cap white and yellow in color should be removed as soon as it happens. The material consists mainly of non-structural material with necrotic and degenerated epithelial cells.
