The following products have recently been introduced by VISITEC
The 5153 Cortex Aspirator/Hydrodissector (angled left) [Alpern] and the 5154 Cortex Aspirator/Hydrodissector (angled right) [Alpern] have recently become available. The two aspiratorlhydrodissector cannulas were developed for aspiration of cortical debris and/or hydrodissection at the difficult to reach 10 to 2 o'clock position. The end of these 25 g cannulas have a j-shaped curve to reach around the superior lip of the capsular bag through a smaller capsulorhexis opening. The 5153 cannula is angled 45° to the left for easier access to the 12 to 2 o'clock position and the 5154 is angled 45° to the right for easier access to the 10 to 12 o'clock position. These cannulas are designed to be used with irrigation to 'fluff up' cortical debris. The cannulas are then connected to a syringe for aspiration. The 5153 and 5154 cannulas may also be used for hydrodissection at the 12 o'clock position. Both the 5153 and 5154 cannulas are double sterile packed for ease of aseptic transfer in the operating room.
The 1089 VISI-SPEAR™ for use in all types of eye surgery for the absorption of blood and fluids from the operative area is also now available. The flat tip allows precise application at the surgical site and facilitates fast wicking offluids. VISI-SPEARS are made with a highly absorbent sponge material enabling fluids to be quickly and efficiently drawn away from the surgical site. VISI-SPEARS are packaged in an easy-to-peel, Tyvek®-backed blister containing five sterile spears. The five pack is more economical and eliminates the waste of unused spears which are discarded at the end of each surgical case. Each box of VISI-SPEARS contains 100 spears (20 packs of five).
The 5167 Nucleus Hydrodissector [Bobbitt] was developed for hydrodissection and hydrodelination in cataract procedures. The double-bend feature of the 5167 prevents the nucleus from rising in the capsular bag during hydrodissection. Also, the angled tip facilitates placement under the anterior capsule for hydrodissection and between the nucleus and epinucleus for hydrodelineation. A video demonstrating the use of the cannula is available from VISITEC. Packaged ten per box.
The 5176 Sub-Tenon Anesthesia Cannula for administering anesthesia prior to ophthalmic surgery has recently been introduced.
The 19 g cannula delivers an efficacous eye block that allows for rapid onset of anesthesia and akinesia without the use of a needle and its associated risks. The cannula is flattened to facilitate advancement into Sub-Tenon's

tissue plane for injection. Also, the cannula features a gentle curve that allows for movement along the contour of the globe, minimizing distortion to the surrounding tissue. The cannula is made for use after a 2 to 3 mm incision is made in the eye's conjunctiva and Tenon's fascia. Then, the 5176 cannula is placed along the globe into the Sub-Tenon's space. Anesthetic is injected, resulting in rapid pupil dilation. The 5176 is provided in a protective sheath and sterile packed with a blister sealed Tyvek® lid to protect the product. Packaged 10 per box.
Three new microsurgical knives for use in ophthalmic procedures have recently become available. The 1112 EdgeAhead Circular Knife was designed to create a scleral tunnel incision for a more precise flap in small incision surgery. The 1128 and 1129 EdgeAhead Phaco Slit knives have been designed to create or enlarge initial stab incision, to accommodate a micro phaco handpiece. The 1112 features a circular blade with a 260° cutting edge for even incision and reduced post-op astigmatism. The narrow 2.25 mm blade provides more control when creating a precise scleral tunnel. The knife is angled 60° 3 mm from the blade tip for easier maneuvering, especially in patients with deep set eyes. This shorter distance decreases surface area and pressure exerted on the eye during tunneling procedures. The 1112 may also be used for trabeculotomy procedures. The circular blade facilitates scleral dissection and incision into the trabecular meshwork.
The 1128 and 1129 EdgeAhead Phaco Slit knives feature a thin profile and super sharp edges for smoother penetration and less tissue distortion. The 1128 is straight and the 1129 is angled 40°; both knives are 2.5 mm wide. The knives have parallel sides for safer removal from the eye. They also feature a matte finish to reduce glare from microscope light. All knives have a sure-grip, no slip handle with a ridge indicating the position of the knife edge. Also, the blade width or product number is inscribed on the knife handle for easy identification. These sterile ready-to-use instruments are packaged with a Tyvek® lid to resist moisture, tearing and puncturing. Individual knife carriers protect each blade until use. Packaged three to a box.

New developments from Katena
A new arcuate incision marker has recently been introduced. Developed by Dr Hugo Nano, Jr. of San Miguel, Argentina, this marker is used to impress a clearly delineated pattern on the cornea, even without marking ink, for placement of arcuate keratotomy incisions. The marking head is designed to fit perfectly into the Mendez Degree Gauge for exact alignment in the axis ofastigma-
