Purpose: To report a 10-year follow-up case of the first lamellar keratoplasty treatment with acellular porcine corneal stroma (APCS).
Methods: A 62-year-old woman was diagnosed with a fungal corneal ulcer and received lamellar keratoplasty treatment with APCS in 2010. The 10-year follow-up results were evaluated by slit lamp biomicroscopy, anterior segment optical coherence tomography, in vivo confocal microscopy, and corneal biomechanics analysis.
Results: The APCS graft maintained good biocompatibility and physical properties in transparency, stromal regeneration, elasticity, and deformation resistance. However, some disadvantages were observed, including a protracted course to eventual clearing, a decreased thickness, corneal depositions, sparsely distributed neural fibers, and low stiffness.
Conclusions: This case indicated that APCS remains stable over a 10-year follow-up period. APCS can serve as a functional stromal surrogate where donor human corneal tissue is unavailable.
