Epiphora is a very common ocular pathology in the small animal practice affecting mainly the brachycephalic breeds of dogs and cats. The material used for manufacturing the device utilized in the procedure is a 3 ½ French “Tom Cat” urethral cannula and a 40 x 16 G needle or 16 G intravenous catheter. After the patient is under anesthesia the device is driven from the puncta and conjunctival nasal fornix (cul-de-sac) through the subcutaneous space just by the nasal bone and exiting the ipsilateral nostril. The device is pulled out till it gets firmly attached and the wider back part of it is cut out just adjacent to the conjunctival tissue. There is no need for stitches, but in some cases one can put a nylon suture that goes through the cannula and embraces the conjunctival tissue. Postoperatively topical antibiotics and steroids are used for 30 days. Results: The new drainage system starts working right after the procedure and the device is very well tolerated and can be left in place in most cases and it is only removed if there is migration. The success rate of this procedure is very high and the tear staining is resolved very fast. Authors: Kleiner, JA. Wouk AF. Vetweb Oftalmologia Veterinária. Website: www.vetweb.com.br..
