Glaucoma surgical intervention is experiencing a renaissance of innovation and growing clinical adoption in 2026, with minimally invasive glaucoma surgery devices and techniques complementing and increasingly replacing traditional trabeculectomy and tube shunt procedures across a widening spectrum of glaucoma severity presentations, and this surgical evolution is creating new ophthalmic knife and instrument requirements that are driving product development across the glaucoma surgical instrument landscape. The Ophthalmic Knives Market glaucoma surgery instrument segment encompasses the paracentesis blades and keratomes used for cataract surgery incision creation when combined glaucoma-cataract procedures are performed, the ab-interno goniotomy knives used for Schlemm's canal and trabecular meshwork procedures, the conjunctival dissection instruments required for traditional filtration surgery, and the specialty access instruments used for suprachoroidal and subconjunctival MIGS device implantation. Minimally invasive glaucoma surgery has expanded the population of glaucoma patients considered appropriate surgical candidates beyond the advanced disease patients traditionally referred for trabeculectomy, as the favorable safety profile of MIGS procedures enables earlier surgical intervention for mild-to-moderate glaucoma patients inadequately controlled by medications who would not previously have been considered appropriate trabeculectomy candidates given its higher complication risk. Ab-interno goniotomy using the Kahook Dual Blade and similar purpose-designed goniotomy instruments provides targeted trabecular meshwork excision through a temporal paracentesis approach, representing a premium ophthalmic knife category with growing adoption among glaucoma surgeons incorporating trabecular bypass as a cataract surgery adjunct.
Traditional trabeculectomy surgery retains an important role for advanced glaucoma requiring the lowest achievable intraocular pressures, and the precision conjunctival dissection, scleral flap construction, and sclerotomy creation that trabeculectomy requires generates demand for the specialty blades, microsurgical scissors, and access instruments that experienced glaucoma surgeons depend on for consistent filtration surgery outcomes. Cyclodestructive procedures using micropulse transscleral laser and endoscopic cyclophotocoagulation are expanding glaucoma surgical options for refractory cases where filtering surgery has failed, reducing but not eliminating the surgical knife requirements for cyclodestructive procedures that require conjunctival and scleral access instrumentation. The integration of intraoperative optical coherence tomography guidance into glaucoma surgery is improving the precision of Schlemm's canal cannulation, trabecular bypass stent placement, and suprachoroidal device delivery, supporting the development of more standardized and reproducible glaucoma surgical techniques that could expand the surgeon base performing these procedures beyond current early adopter subspecialists.
Will the minimally invasive glaucoma surgery revolution, by expanding the population of glaucoma patients receiving surgical intervention and creating new specialized instrument categories, generate net growth in the glaucoma surgical instrument market that more than offsets any reduction in traditional trabeculectomy instrument demand?
FAQ
- What are the most important ophthalmic knife innovations specifically designed for minimally invasive glaucoma surgery? Purpose-designed ab-interno goniotomy instruments including the Kahook Dual Blade for trabecular meshwork excision, gonioscopy-assisted transluminal trabeculotomy sutures and probes for Schlemm's canal expansion, and suprachoroidal MIGS device implantation access systems represent the most commercially significant ophthalmic knife and instrument innovations developed specifically for minimally invasive glaucoma surgery approaches that have expanded glaucoma surgical treatment options.
- How does combined glaucoma-cataract surgery affect ophthalmic knife demand? Combined phacoemulsification cataract surgery with concurrent MIGS glaucoma procedure is the most rapidly growing glaucoma surgical category, performed through the same temporal paracentesis and keratome incisions used for standalone cataract surgery with the addition of gonioscopy-guided trabecular or canal instruments introduced through the existing paracentesis, creating incremental demand for the specialized MIGS instruments added to the existing cataract surgery instrument set rather than requiring a completely separate surgical setup.
