Sklar Barkan Goniotomy Knife, 4-1/2 Inch
A 4-1/2 inch ophthalmic knife used to incise the trabecular meshwork precisely during goniotomy, most often performed for congenital glaucoma. It is supplied for repeated sterilization and reuse in hospital and clinic settings.
The Sklar Barkan Goniotomy Knife is a 4-1/2 inch ophthalmic surgical knife used to make a precise incision into the trabecular meshwork during goniotomy, a procedure performed most often to treat congenital or early childhood glaucoma by improving the drainage of aqueous humour from the eye. The knife's fine blade is designed for controlled, shallow incisions under gonioscopic visualisation, where the surgeon views the anterior chamber angle through a special lens while advancing the blade with great precision, since the anatomical structures involved are extremely delicate and closely packed.
This is a highly specialised instrument used almost exclusively by pediatric ophthalmologists and glaucoma specialists performing goniotomy, a procedure that differs from the more commonly known trabeculectomy in both technique and the patient population it typically serves. Because of its specialised role, this knife is kept in a dedicated pediatric glaucoma or goniotomy surgical tray rather than a general ophthalmic set, and it is reprocessed and sterilized with the same care applied to other fine ophthalmic cutting instruments.
