Epi-LASIK: histological findings of separated epithelial sheets 24 hours after treatment.

PURPOSE: To report the histological findings of four eyes of three patients who underwent epi-LASIK treatment for the correction of low myopia. METHODS: The epithelial sheets were harvested either immediately after separation (one eye) or were accidentally dislocated and harvested from [he operative eyes 24 hours after treatment (three eyes). All sheets underwent optical and transmission electron microscopy. RESULTS: Histological evaluation showed that the majority of the epithelial cells were morphologically normal in all examined specimens. CONCLUSIONS: Histological examination of specimens in four eyes showed that 24 hours after mechanical separation the epithelial cells' morphology was close to normal.
