A partial-thickness 'scleral belt loop' for MicroShunt implant

Area of Science:

• Ophthalmology
• Surgical Innovation

Background:

• Glaucoma drainage devices like the PreserFlo MicroShunt aim to reduce intraocular pressure.
• Standard implantation techniques can sometimes lead to complications such as conjunctival erosion and inflammation.

Purpose of the Study:

• To introduce and describe a new surgical technique for PreserFlo MicroShunt implantation.
• To enhance the adherence of the MicroShunt to the scleral profile and minimize postoperative complications.

Main Methods:

• A partial-thickness scleral belt loop is created prior to Tenon's capsule and conjunctiva repositioning.
• The MicroShunt's distal end is passed under the scleral belt, leaving the tip uncovered by the loop.

Main Results:

• The technique ensures perfect adherence of the MicroShunt to the scleral profile in all cases.
• The uncovered tip avoids stressing the conjunctival flap during eye movements, reducing erosion and inflammation.

Conclusions:

• This modified technique is efficient and easily integrated into standard procedures without additional cost.
• It effectively minimizes conjunctival complications and may reduce the need for filtration bleb surgical revisions.
