Superficial keratectomy
Superficial keratectomy, also known as "Super K" or "corneal epithelial debridement", is an ophthalmic surgical procedure takes place on the surface of the cornea to remove irregularities or scars.
SK involves removing the epithelial layer of the cornea leaving the bowman's membrane undisturbed. Often, the bowman's layer is polished and smoothed with a diamond tip burr or laser which encourages anchoring of the new epithelium as it grows back. Many doctors will use the antibiotic Mitomycin or an amniotic membrane transplant to improve surgical outcomes.
Common conditions that require SK
- Epithelial Basement Membrane Dystrophy
- Recurrent Corneal Erosion Syndrome
- Salzmann's Nodular degeneration
- Superficial corneal scar
- Removal of Band Keratopathy
Complications
There are a few risks to consider before performing or receiving SK. Although SK is considered a low risk procedure, some patients will experience complications such as:- infection of the cornea
- corneal haze
- delayed or failed epithelial healing
- corneal erosion
