Dilators, Surgical, Eye, Lacrimal Canal

Definition : Surgical dilators designed for mechanically augmenting the diameter of the lacrimal canal during ophthalmic surgery. These surgical dilators typically consist of a handheld instrument with a very fine, blunt, tapered distal end to facilitate placement; some are double-ended instruments. Lacrimal canal dilators vary according to the surgical procedure to be performed; some smooth tapered end lacrimal canal dilators typically made of stainless steel are used for dilation of the lacrimal canal punctum, frequently followed by irrigation of the nasolacrimal system. Lacrimal canal dilators are used during ophthalmic procedures (e.g., to release mucous plugs or concretions, to produce temporary relief in a case of stenosis of the punctum and/or prior to inserting punctum plugs and syringes).
