Epithelial Ingrowth

Epithelial ingrowth post LASIK surgery 

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.
