Abstract
To report a 10-year follow-up case of the first lamellar keratoplasty treatment with acellular porcine corneal stroma (APCS). 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. 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. 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.
