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.

A 15-year-old, spayed, female American shorthair cat presented with recurrent corneal sequestrum in the right eye. The cat had undergone superficial keratectomy twice for corneal sequestrum treatment 5 and 11 months previously. Two layers of porcine small intestinal submucosa (SIS; Vetrix BioSIS®) were applied to the surgical corneal defect after keratectomy. Thereafter, clinical signs, such as lacrimation, blepharospasm, and corneal ulcer, disappeared 50 days postoperatively. Moreover, the application of SIS with keratectomy prevented recurrence until 651 days after surgery. SIS could be applied as an additional bioscaffold for surgical repair of corneal sequestrum recurring after superficial keratectomy alone in cats.
