Tel: 0191 519 0111 E. Mail: admin@altomed.com or quality@altomed.com Processing, Handling and Care These devices can go through a standard validated washer /disinfector cycle, and the standard 134°C - 137°C autoclave cycle with a 3 to 3 ½ minute holding time. For full details, please see Instruction Sheet ALT I013 Altomed Limited – Reprocessing Reusable Stainless Steel and Titanium Devices available from Altomed Limited either at the above contact details or on-line at www.altomed.com/resources. Inspection It is very important after decontamination that the tips of these devices are inspected for any signs of damage prior to being released for sterilization. The devices must also be inspected under the microscope prior to insertion in to the eye to ensure no physical damage has occurred during the packaging and sterilization, and the handling and unpacking procedure prior to the operation. Check for signs of any physical damage such as cracks, chips, bends, dents, scratches, jagged edges, snapped tips or any other physical defomormity. Ensure the device is clean with no unwanted debris, fibres etc attached. The device tips are very delicate as they are designed to function inside the eye and as such need to be very small. If they are dropped, knocked against a hard surface or come into direct contact with the tip of a Phacoemulsification (Ultrasonic) Handpiece they can become damaged and may snap during use. Warnings In order to prevent accdiental trauma, ensure the patient’s head is unable to move during the procedure. Do not let the tip of the manipulators contact the Phacoemulsification (Ultrasonic) Handpiece as this causes physical damage to the tip of the manipulator and may cause it to break off during use. We would recommend care to avoid inadvertent contact between instruments within the anterior chamber during phacoemulsification. Tears of Descemet’s membrane are common operative occurrences. Small tears typically do not result in major complications. Larger tears, however, can result in significant and persistent postoperative corneal edema with a severe reduction in the patient’s visual acuity. Tears of Descemet’s membrane are commonly caused by improper insertion of an instrument through the incision. Because most corneal incisions are triplanar, the instrument tip should be introduced in a similar fashion. It is particularly important to push the tip posterior when entering the anterior chamber. A second recommendation to help avoid Descemet’s tears is to avoid forcing an instrument or the intraocular lens through a tight incision. It is better to enlarge the incision. Additionally, care should be taken to avoid mechanical trauma to the iris by intraocular instruments. Proper incision placement and construction will minimize the risk of iris prolapse with subsequent damage to the iris sphincter and stroma. Sudden pressure and volume changes will induce vitreous prolapse. Thus, it is imperative to gently stabilize and replace volume in the anterior chamber with balanced salt solution or viscoelastic before withdrawing instruments from the anterior chamber. Intended Purpose and Use: Used for manipulating the natural and artificial lens and surrounding tissue. These are reusable devices.
