Membrane-tube-type glaucoma shunt device for refractory glaucoma surgery.

Area of Science:

• Ophthalmology
• Surgical Devices
• Glaucoma Research

Background:

• Refractory glaucoma requires advanced surgical solutions.
• Existing treatments may have limitations in efficacy or safety.
• Novel shunt devices aim to improve intraocular pressure control.

Purpose of the Study:

• To evaluate the safety and efficacy of the Finetube membrane-tube (MT)-type glaucoma shunt.
• Assess the performance of this novel device in patients with refractory glaucoma.
• Determine the device's potential for improving outcomes in challenging glaucoma cases.

Main Methods:

• Implantation of the Finetube MT shunt in 44 eyes with refractory glaucoma.
• The device features an expanded polytetrafluoroethylene reservoir and a silicone tube with a stent.
• Post-operative monitoring included intraocular pressure (IOP), medication use, and complications.

Main Results:

• Mean IOP reduced by 48.5% one year post-surgery (32.8 to 16.9 mmHg; p<0.01).
• The number of IOP-lowering medications decreased significantly (2.5 to 1.1; p<0.01).
• Success rates were 92.4% at 1 year and 85.0% at 3 years; no hypotony or tube exposure occurred.

Conclusions:

• The Finetube MT shunt shows promising outcomes for refractory glaucoma.
• The device offers a safe and effective treatment option.
• Minimal postoperative complications, including hypotony and tube issues, were observed.
