Cornea: debridement

Synonym(s): Grid keratotomy

Contributor(s): Dennis E Brooks, Natasha Mitchell, Peter Renwick, David Williams

Introduction

  • Debriding the corneal epithelium removes non-attached epithelium and promotes healing by stimulating the release of inflammatory mediators and provides roughened surface for attachment of new epithelium.
    Recent opinion suggests that keratotomies in cats may predispose some cats to subsequent sequestrum formation.Gentle debridement may be a safer alternative to more aggressive grid, punctate or diamond burr keratotomies.

Uses

Disadvantages

  • Corneal sequestrum formation is more likely after a keratotomy, and after a chronic ulcer.
