Abstract

Purpose

To describe and report long-term outcomes of a surgical technique in advanced pellucid marginal degeneration (PMD) combining conventional central penetrating keratoplasty (PK) with an additional crescentic inferior keratoplasty, using a single corneal transplant.

Results

We report the case of a 55-year-old male patient, who underwent a customized sizing PK in his right eye for an advanced PMD, which combined a central PK with an additional crescentic inferior keratoplasty. The 1 year postoperative results show very good clinical outcomes, including visual acuity and biomechanical parameters, as well as tectonic outcomes, documented with high resolution optical coherence tomography (OCT) at the junction site between the two grafts.

Conclusion

Advanced PMD is a specifically challenging condition for keratoplasty due to an extreme peripheral corneal thinning. This surgical technique may facilitate inferior suturing and optimize the postoperative tectonic outcomes.
