Parotid duct transposition is a specialized surgical procedure offered at Eye Clinic, aimed at pets facing issues with inadequate tear production. This surgical technique diverts the parotid salivary gland duct toward the eye, allowing saliva to substitute for tears and keep the eye lubricated.

This procedure is recommended for patients who have not responded to conventional dry eye treatment or for those in whom other surgical techniques have failed. While saliva is not identical to tears, it has proven to be an effective substitute in many cases for maintaining the ocular surface hydrated and comfortable.
