• The bend of an anterior segment 30° bent infusion needle allows for ease of positioning over the nose or brow during surgical procedures. This instrument is easily used in bimanual surgical techniques with standard vitrectomy probes. Infusion into the anterior chamber of the eye during anterior segment vitrectomy procedures has the advantage of maintaining the depth of the anterior chamber and preventng its collapse during surgery. This technique is particularly useful in anterior membranectomy, capsulectomy, lensectomy, and other anterior segment procedures.
