Trabectome

A trabectome is a surgical device that can be used for ab interno trabeculotomy, a minimally invasive glaucoma surgery for the surgical management of adult, juvenile and infantile glaucoma. The Ttrabecular meshwork is a major site of resistance to aqueous humor outflow. As angle surgeries such as Trabectome follow the physiologic outflow pathway, the risk of complications are significantly lower than filtering surgeries. Hypotony with damage to the macula (hypotony maculopathy), that can occur with pressures below 5 mmHg for instance after traditional trabeculectomy, because of the episcleral venous pressure limit. The Trabectome handpiece is inserted into the anterior chamber, its tip positioned into Schlemm's canal and advanced to the left and to the right. Different from cautery, the tip generates plasma to molecularize the trabecular meshwork and remove it drag-free and with minimal thermal effect. Active irrigation of trabectome surgery system helps to keep anterior chamber formed during the procedure and precludes the need for ophthalmic viscoelastic devices. Viscoelastics tend to trap produced debris or gas bubbles and diminish visualization. The Trabectome decreases the intra-ocular pressure typically to a mid-teen range and reduces patient's requirement to take glaucoma eye drops and glaucoma medications (see references). The theoretically lowest pressure that can be achieved is equal to 8 mmHg in the episcleral veins. This procedure is performed through a small incision and can be done on an outpatient basis.
