Lamellar Keratoplasty (LK)
Educational only: videos on MedicalVideos.com are for general information and are not medical advice. Always consult your own doctor about your health.
Most corneal transplants performed in the U.S. involve replacing the entire thickness of the diseased cornea with a healthy donor cornea (called penetrating keratoplasty or PK). In partial-thickness corneal transplants (LK), only the anterior (surface) layers of the cornea are removed. The donor cornea is then attached to the host corneal bed, containing only posterior (deeper) layers. LK is less risky, but tends to result in somewhat inferior vision vs. PK and cannot be performed if the disease process (e.g. scar) involves the deeper layers of the cornea.

The video explains lamellar keratoplasty, a partial-thickness corneal transplant. It contrasts this approach with penetrating keratoplasty, in which the full thickness of the cornea is replaced, and notes the situations and limitations described for the partial-thickness procedure.
Key points
- Explains replacement of only the anterior layers of the cornea in lamellar keratoplasty
- Contrasts lamellar keratoplasty with full-thickness penetrating keratoplasty
- Covers attachment of donor tissue to the remaining deeper host corneal bed
- Notes that disease involving deeper layers cannot be treated this way as described
