DALK
DALK
When the keratoconus is in a very advanced stage, a replacement of the cornea is indicated.Since the disease touches only the anterior 2 ⁄ 3 of the cornea ,it becomes obvious that there is no need to replace the posterior 1 ⁄ 3,that’s what Deep anterior Lamellar Keratoplasty is about !DALK is a modern technique whereby the outer two layers of the cornea are removed and replaced with the outer two layers from a donor cornea to give a partial-thickness transplant.
Advantage :
- Closed eye surgery
- No chance of blinding Endothelial rejection (by retaining the recipient’s own endothelial layer)
- Can always perform a Penetrating Keratoplasty if visual results are not satisfactory
