Background: Descemetocele is a lesion on the descemets membrane most often caused by very deep ulcerations in the cornea, where the epithelium, basement membrane and stroma layers are exposed, leading to a distortion of the corneal structure. Because it is an injury whose evolution can lead to loss of vision, Descemetocele is considered a surgical emergency because, within the various techniques adopted, there is always an attempt to preserve the ocular bulb. Thus, the adoption of various reconstructive keratoplasty procedures have been described in descemets membrane repair and ocular perforations of varying degrees of extension. In this surgical technique, tissue fragments (autogenous, autologous or xenologous) are usually used, the surgical method being defined according to the degree of injury (partial or total) and the amount of tissue required to be replaced. The aim of this study was to report a case of Keratoplasty with a third eyelid covering for descemetocele correction with corneal perforation in a domestic cat. Case: A 2-year-old feline female was treated at the Veterinary Hospital of the University of Amazonia (UNAMA), presenting a traumatic ocular lesion with evolution of more than 25 days, refractory to treatment as eye drops. The ophthalmologic examination revealed presence of extravasated polymerized necrotic tissue in the cornea of the left eye, with Descemetocele as diagnosis. The treatment indicated was Reconstructive Keratoplasty without graft with third eyelid coating. As an anesthetic protocol, MPA was used with acepromazine, ketamine hydrochloride as the inducing agent and isoflurane in mask vaporization for the maintenance of the anesthetic plane. After preparation of the patient, the surgical procedure consisted of excision with a scalpel blade of the necrotic tissue, exposure of the endothelial layer and suture of the cornea with Vincryl®, in a simple discontinuous pattern.
