Plain-English summary
A group of 13 domestic cats, mostly Persian, underwent corneal graft surgery to treat corneal sequestrum, a condition where part of the cornea dies and can cause vision problems. After the surgery, which involved either a partial or full-thickness graft, all cats showed good visual improvement, with most having only mild cloudiness in their corneas. They received post-surgery care that included antibiotics and anti-inflammatory medications. The average healing time for the corneas was about 19 days, and complications were minimal. Overall, the surgery was successful in restoring vision and improving the appearance of the affected eyes.

Abstract
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.
