Cornea: superficial keratectomy

Synonym(s): Superficial keratectomy

Contributor(s): Paul Gerding, Natasha Mitchell

Introduction

  • Surgical excision of the outermost portion of the cornea aims to remove diseased or abnormal superficial corneal tissue.

Uses

Disadvantages

  • The depth of the sequestrum can be difficult to determine. During surgery, it may become apparent that a deeper keratectomy is required. If so, the surgeon needs to be prepared to do a grafting procedure such as a conjunctival pedicle graft Conjunctival graft or sliding corneo-conjunctival transposition.

Procedure

  • Depends on extent of cornea being removed + skill of surgeon (including availability of fine instruments and magnification).
