The Handpiece is a sterile single use ophthalmic knife. It consists of a pencil-like instrument with a graspable white ABS plastic outer shell (~1.5 cm diameter and ~13 cm length), and a stainless steel probe (protruding about 2.2 cm from the tip of the white outer shell and covered by a protective purge chamber). The diameter of the probe insertable into the eye is ~1.1 mm. The tip of the probe features a pointed footplate tip and dual sharpened edges fabricated of stainless steel.The Handpiece is intended to be used in ophthalmic surgery to manually cut Trabecular Meshwork (TM) in adult and infantile patients.
A sterile, hand-held manual ophthalmic surgical instrument designed to make precise incisions in the eye and surrounding tissues during ophthalmic surgery. It is typically designed as a one-piece instrument with a sharp, single-edged cutting blade at the distal tip and a handle at the proximal end. It can have a variety of blade edge shapes, e.g., phaco (blunt or sharp), crescent, straight, and micro-phaco (for micro incision cataract surgery). It is usually made of high-grade stainless steel and some types can employ silicon (i.e., a brittle metalloid material) blades. This is a single-use device.
