- Clinical features:
- Symptoms: decreased best-corrected vision.
- Signs: corneal epithelial cells invade and grow under the corneal
flap.
- Possible causes: implantation of epithelial cells during surgery,
poor-quality blade, improper repositioning of the flap or gap between
stromal bed and flap.
- Complication:
- Irregular astigmatism
- Flap melting
- Treatment: re-elevating the flap and irrigation with scraping of
the stromal bed as well as the flap undersurface.
