A four-year-old, intact male, Greyhound presented with a large corneal perforation in the right eye (OD). There were many eye-worms in both of the patient’s eyes. Ophthalmic examination revealed conjunctival hyperemia, corneal edema, corneal perforation and iris prolapse, and menace response and pupillary light reflex were absent whereas the dazzle reflex was present in the OD. Ophthalmic examination of the left eye (OS) revealed conjunctival hyperemia, keratitis, mild corneal edema, and the neuro-ophthalmic examination confirmed menace response, palpebral reflex, dazzle reflex, and pupillary light reflexes were present. Adult eye-worms were removed with forceps from both eyes under general anesthesia. Then allogeneic lamellar keratoplasty and equine amniotic membrane transplantation were planned for treatment. At 112 days after surgery, the patient’s vision had recovered sufficient vision to do outdoor activities though there was slight scarring. This case demonstrates the potential for good visual recovery following allogenous tectonic lamellar keratoplasty.
