Tear Bypass Tube
Tear Bypass Tubes - Lester Jones Tubes
When the canaliculi are scarred, absent or non-functional, a bypass tube is inserted to allow tears to drain through to the nose, bypassing the abnormal canaliculi. These tubes are called Lester Jones tubes and are made of medical grade Pyrex.
Dr Ye Chen may place the tube at the time of your DCR surgery or at a subsequent procedure.
Lester Jones tubes are placed through a narrow tract which contracts around the tube while it heals. A suture is temporarily placed around the tube to secure it while the tract is healing.
