Conjunctivodacryocystorhinostomy using a high-density porous polyethylene-coated tear drain tube

Area of Science:

• Ophthalmology
• Oculoplastics
• Medical Devices

Background:

• Epiphora, or excessive tearing, often results from blockages in the lacrimal drainage system.
• Traditional treatments may have limitations, necessitating innovative solutions for effective tear drainage.

Purpose of the Study:

• To assess the efficacy and outcomes of conjunctivodacryocystorhinostomy (CDCR) utilizing a novel high-density porous polyethylene (HDPP)-coated tear drain tube.
• To evaluate the patency and patient-reported relief from epiphora after lacrimal bypass surgery with the HDPP-coated tube.

Main Methods:

• A prospective interventional case study was conducted on patients experiencing epiphora due to proximal lacrimal system obstruction.
• Twenty-two eyes underwent lacrimal bypass surgery employing the HDPP-coated tear drain tube.
• Outcomes were evaluated over a follow-up period ranging from 12 to 41 months.

Main Results:

• A high success rate was observed, with 21 out of 22 eyes demonstrating a patent and well-positioned HDPP-coated tube.
• Subjective relief of epiphora was reported in the majority of treated eyes.
• One case involved a loose sleeve noted during surgery, leading to postoperative tube dislodgement and removal.

Conclusions:

• The HDPP-coated tear drain tube is a viable option for lacrimal bypass surgery, achieving a high success rate with minimal complications.
• Further long-term follow-up is recommended to monitor for potential tube blockage caused by conjunctival or nasal mucosal overgrowth.
