A hand-held manual ophthalmic surgical instrument intended to be used to perform a trabeculotomy [surgical opening of the sinus venosus sclerae (Schlemm’s canal)] to reduce intraocular pressure (IOP) for the prevention/treatment of glaucoma. It is typically made of high-grade stainless steel, having a two-pronged fork at the distal end and a handle at the proximal end. It enables guided unroofing of Schlemm's canal (an endothelium-lined tube) through insertion of one of the prongs via incisions and flaps made in the eye. This is a reusable device.
