Jones tubes, a type of canalicular bypass tube, can last for decades. Some patients maintain their original Jones tube for over 30 years with proper care, offering insights into long-term device expectations.

Area of Science:

  • Ophthalmology
  • Oculoplastics
  • Tear Drainage Surgery

Background:

  • Canalicular bypass tubes, such as Jones tubes, are used to treat nasolacrimal duct obstruction.
  • Lester Jones described these tubes approximately 50 years ago.

Purpose of the Study:

  • To evaluate the long-term outcomes and durability of Jones tubes placed decades ago.
  • To provide data for counseling patients on the expected lifespan of bypass tubes.

Main Methods:

  • Retrospective review of living patients who had Jones tube placement between 1969 and 1989.
  • Analysis of tube duration, replacement frequency, and patient outcomes at last follow-up within the last 15 years.

Main Results:

  • 33 eyes from 29 patients with Jones tubes placed before 1990 were reviewed, with an average follow-up of 29.5 years.

  • The original Jones tube remained functional in 24% of eyes at a mean of 34 years.
  • 11% of eyes lost their tubes, with most experiencing minimal symptoms.

    • Conclusions:

    • Jones tubes can be tolerated for over four decades, demonstrating significant long-term efficacy.
    • Some patients can retain their originally placed Jones tube for life with appropriate maintenance.
    • This study offers valuable data for patient counseling regarding the longevity of canalicular bypass devices.
