Deep lamellar keratoplasty (DLKP) offers superior outcomes compared to penetrating keratoplasty (PK), with no rejection episodes and faster visual recovery. DLKP preserves endothelial cells and reduces astigmatism, making it a preferred corneal transplant method.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Transplantation

Background:

  • Deep lamellar keratoplasty (DLKP) involves removing the entire corneal stroma down to Descemet membrane.
  • DLKP offers a distinct anatomical cleavage plane for clear stromal separation.

Purpose of the Study:

  • To compare the outcomes of 200 deep lamellar keratoplasty (DLKP) cases with 200 penetrating keratoplasty (PK) cases.
  • Evaluate the efficacy and safety of DLKP versus PK in corneal transplantation.

Main Methods:

  • Comparative study of 200 DLKP and 200 PK procedures.
  • Assessment of rejection episodes and endothelial cell count post-surgery.

Main Results:

  • No rejection episodes observed in DLKP group, compared to 4% in PK group.

Related Experiment Videos

  • Endothelial cell count was double in DLKP patients versus PK patients one month post-surgery.
  • DLKP demonstrated significantly reduced astigmatism and faster functional recovery.

    • Conclusions:

    • DLKP preserves endothelial cells, unlike PK which causes substantial reduction.
    • DLKP is a superior corneal transplantation technique due to reduced astigmatism and faster recovery.
    • DLKP is recommended as the preferred procedure when endothelial damage is absent.
