Eye cannulae, polymer-metal, sterile, of different standard sizes, for injection of solution into the anterior chamber, hydrodissection, probing of lacrimal passages, anaesthesia and aspiration, a hole diameter from 0.4mm to 1.2mm and a length from 22mm to 36mm.
Suction-irrigation eye cannula (double-channel) is used to aspirate the lens masses when simultaneous irrigation with the humor substituting fluids at extracapsular cataract extraction. Reusable cannula is highly resistant to treatment cycle consisting of disinfection, presterilizing clearing under the OST 42-21-2-85 standard. The suction and irrigation tubes contacting with the tissues of the body are made by electroforming of electrolytic nickel. The cannula is equipped with silicone tubing to connect the system to Luer and Record syringes. Eye cannula is used in eye surgeries. After removal of the body of the eye lens the cannula is attached to the suction-irrigation system and inserted into the posterior chamber of the eye. The curved end of the cannula is parallel to the rear side of the phacocyst. Irrigation fluid flowing from the side opening of the irrigation tube is directed along the back surface of the phacocyst irrigating lenticular mass. Reaching the equator of crystalline lens, the irrigation liquid is returned toward the front of the phacocyst, and is sucked into the oval suction opening located at the end of the irrigation tube. Liquid vortex flow cleans the phacocyst very carefully.
Eye cannula is packed into an impact-protected plastic case.
