Minimally invasive external mini-glaucoma shunt implantation without conjunctival dissection

Area of Science:

• Ophthalmology
• Surgical Innovation
• Glaucoma Management

Background:

• Traditional Ex-PRESS Glaucoma Filtration Device implantation involves conjunctival peritomy, scleral flap creation, and suture closure.
• This established technique carries risks of conjunctival wound leaks and significant scarring.

Purpose of the Study:

• To introduce and evaluate a novel, minimally invasive technique for Ex-PRESS shunt implantation.
• To assess the safety and efficacy of this new approach compared to the conventional method.

Main Methods:

• The new technique utilizes a scleral tunnel approach originating from a grooved clear corneal incision.
• This method bypasses the need for conjunctival dissection and subsequent closure.

Main Results:

• The minimally invasive technique eliminates the requirement for conjunctival dissection and closure.
• It inherently prevents conjunctival wound leaks by design.
• The procedure maintains partial thickness scleral coverage for the shunt.

Conclusions:

• This novel technique offers a potentially faster and safer alternative for Ex-PRESS shunt implantation.
• It may lead to reduced conjunctival scarring and improved patient outcomes in glaucoma surgery.
