It consists of several layers of cells. The cells of the deepest layer are columnar; then follow two or three layers of polyhedral cells, the majority of which are prickle cells similar to those found in the [[stratum mucosum]] of the cuticle. Lastly, there are three or four layers of [[squamous]] cells, with flattened [[cell nucleus|nuclei]]. == Cornea Cell LASIK Complication == Epithelial ingrowth is a LASIK complication in which cells from the cornea surface layer (epithelial cells) begin to grow underneath the corneal flap. Epithelial ingrowth is a rarely occurring [[LASIK]] complication, appearing in less than one percent of LASIK procedures. However, the incidence of epithelial ingrowth appears to be higher after subsequent enhancement LASIK procedures. This complication is not present in [[PRK]] or other non-flap vision correction procedures. ==See also== * [[Stratified squamous epithelium]] == Disorders == *[[Recurrent corneal erosion]] == External links == [http://www.lasikbenefitsusa.com/lasik-facts/corneaingrowth.html Epithelium Ingrowth After LASIK] {{Eye}} [[Category:Eye]]
