This case report demonstrates using one donor cornea for two corneal transplantations: deep anterior lamellar keratoplasty (DALK) and Descemet stripping with endothelial keratoplasty (DSEK). This innovative approach offers a viable solution for urgent cases and donor cornea shortages.

Area of Science:

  • Ophthalmology
  • Transplantation Surgery
  • Corneal Surgery

Background:

  • Corneal transplantation is a common procedure to restore vision.
  • Donor cornea scarcity presents a challenge for widespread treatment.
  • Lamellar keratoplasty techniques like DALK and DSEK offer alternatives to full-thickness grafts.

Observation:

  • A single donor cornea was utilized for two distinct procedures: DALK for herpetic stromal necrosis and DSEK for pseudophakic bullous keratopathy.
  • The DALK procedure involved dissecting a 400-450 micrometer lamellar graft from the donor cornea.
  • The remaining posterior corneal layers (100-150 micrometers) were successfully used for the DSEK procedure.

Findings:

  • The DALK procedure on the eye with imminent perforation resulted in preserved globe integrity and a best-corrected visual acuity (BCVA) of 20/40.

  • The DSEK procedure on the eye with pseudophakic bullous keratopathy achieved a clear graft, BCVA of 20/30, and good corneal function.
  • This dual-graft technique demonstrated successful outcomes for both anterior and posterior corneal pathologies using a single donor cornea.

    • Implications:

    • This case highlights the potential to maximize donor cornea utilization in lamellar keratoplasty.
    • The technique could be particularly valuable in situations with urgent DALK needs, long DSEK waiting lists, and limited donor tissue availability.
    • While challenges exist, this approach offers a promising strategy to address donor cornea shortages in ophthalmic surgery.
