    Silastic tubing offers a pliable and less irritating option for canalicular intubation compared to Teflon. This method shows promise for obstructed canaliculi, with good to improved results in most patients.

    Area of Science:

    • Ophthalmology
    • Oculoplastic Surgery

    Background:

    • Canalicular intubation is a common procedure for managing nasolacrimal duct obstruction.
    • Previous materials like Teflon and polyethylene have been used, but may cause irritation.

    Purpose of the Study:

    • To evaluate the efficacy and patient outcomes of canalicular intubation using Silastic tubing.
    • To compare the characteristics of Silastic tubing with other materials like Teflon.

    Main Methods:

    • A series of ten patients underwent canalicular intubation using Silastic tubing.
    • Patients were assessed for outcomes, including success rates and complications.

    Main Results:

    • Silastic tubing demonstrated good pliability and capillary action with reduced irritation.

  • Five patients achieved very good results, three showed improvement, and two experienced failures.

    • Conclusions:

    • Silastic tubing is a viable and potentially superior material for canalicular intubation.
    • The technique is most effective in cases of canalicular obstruction near the sac with minimal scarring.
