Objective To determine the clinical outcome of corneal grafting for the treatment of feline corneal sequestrum ( FCS ). Animal studied Domestic cats. Procedures A review of the medical records of cats that underwent keratoplasty as a treatment of FCS at the VTH ‐ UAB , from 2002 to 2012, was carried out. Results Thirteen cats (18 eyes) of different breed, age, and gender were included. Persian cats were overrepresented (12/13;92%). There were nine males and four females, of a mean age of 3.4 years (0.7–7.1). Ipsilateral chronic corneal ulceration was reported as the most common concurrent ocular disease (6/18;33%). Keratoplasty was performed bilaterally in 5 cats (5/13;38%) and unilaterally in 8 (8/13;62%). Lamellar keratoplasty was performed in 17 eyes (17/18;95%) and full‐thickness keratoplasty in 1 (1/18;5%). Mean graft size was 8.3 mm (4–11.5). Fresh homologous graft was performed in 2 eyes (2/18;11%) and frozen graft in 16 (16/18;89%). Of the latter group, homologous graft was performed in 6 eyes (6/16;37.5%) and heterologous in 10 (10/16;62.5%). In all the cats, postoperative treatment included topical antibiotics, corticosteroids, cycloplegics, and 0.2% cyclosporine A. Median follow‐up time was 18.2 months, and main postoperative complications were diffuse mild epithelial pigment formation (2/18;11%), graft malacia (1/18;5%), and sequestrum recurrence (1/18;5%). Mean epithelial healing time was 19.2 days. Good visual outcome was achieved in all the eyes (100%), the majority of them having faint or mild corneal opacity (15/18;83%). Conclusions Keratoplasty is an effective surgical treatment for FCS . The donor tissue provides excellent tectonic support to the affected corneas, with good visual and cosmetic outcome.
