AI Technical Summary
Existing surgical procedures for treating glaucoma, such as goniotomy and ab interno trabeculectomy, face challenges in completely removing trabecular meshwork (TM) without leaving residual leaflets, leading to potential obstruction and elevated intraocular pressure, and require costly and complex equipment with a steep learning curve.
A dual-blade ophthalmic knife designed to conform to the Schlemm's canal anatomy, featuring a ramp-like blade configuration that elevates TM away from the canal's inner wall for precise cutting, minimizing residual leaflets and adjacent tissue damage, and is cost-effective with no moving parts or cautery.
The dual-blade knife achieves complete TM removal with reduced scarring and tissue damage, offering a cost-effective, minimally invasive solution suitable for widespread access, particularly in underserved areas, with improved IOP-lowering efficacy.
