Troeltsch Paracentesis Needle 18cm

Clinical Application

Designed for controlled entry into the anterior chamber, this instrument is used to perform paracentesis for decompression, removal or sampling of aqueous, and to facilitate intraocular procedures where a small, precise entry is required. Common applications include cataract and glaucoma procedures, management of elevated intraocular pressure, and limited emergency anterior chamber decompression.

Design & Configuration

The straight 18 cm shaft provides a balance of reach and tactile feedback, enabling the surgeon to maintain fine control while working in the restricted anterior chamber environment. The hand-held hub allows single-handed manipulation and precise depth control; the fine beveled tip minimizes tissue disruption at entry and supports a smooth, predictable penetration of the corneal or limbal tissue. The slender profile reduces corneal distortion and facilitates concurrent use of fixation forceps or a second instrument.
