Surgical Treatment of Corneal Sequestrum with Porcine Urinary Bladder Submucosa Extracellular Matrix (acell Vet® Corneal Disc) in Two Cats

Two cats were presented to the Dana Animal Hospital Eye Center and were diagnosed with corneal sequestrum through full ophthalmic examination.After lamellar keratectomy using a reusable corneal trephine blade and a crescent microsurgical knife, porcine urinary bladder submucosa extracellular matrix (UBM, ACeLL Vet ® corneal disc) was applied to the corneal defects.In both cases, no corneal sequestrum recurrences were observed until 119 days and 253 days after the surgery, respectively.Porcine UBM could be recommended as a surgical scaffold for treatment of corneal sequestrum in cats.
