Surgical procedures for watery eyes include dacrocystorhinosotomy, or DCR, and eyelid surgery if entropion or ectropion is causing the tearing. In entropion, the eyelid turns inward, while it turns outward in ectropion.
During dacryocystorhinostomy, the surgeon removes a bit of bone from the side of the nose and inserts either a Jones or Crawford tube, which are types of drains. The doctor can also perform the operation through the nose. Unlike traditional dacryocystorhinostomy, the patient's tear sacs are involved. The surgeon makes an opening into one of the patient's tear sacs to allow drainage. This endoscopic surgery is generally not as effective as a traditional dacryocystorhinostomy but lowers the risk of complications and does not leave a visible scar.
During ectropion surgery, the surgeon removes a bit of the eyelid. Sutures tighten the muscles and tendons of the eyelid, which helps it to close correctly. The doctor takes the stitches out after about a week. If the ectropion is a result of trauma, the doctor may repair it with a skin graft.
Entropion treatment may involve a few stitches that help the eyelid turn outward. This is an outpatient procedure performed under local anesthesia. Full entropion surgery is much like ectropion surgery.
