manufacturers item name: barron vacuum punch 7.5mm; used for donor of cornea transplants; stainless steel blade permanently mounted in a nylon housing; four steel guide posts perfectly corresponding holes in the cutting block base, automatically centering the donor cornea; circular groove for aspirating the epithelial side of the cornea immobilizing it for cutting the button; cutting block base has four small holes which can be inked with a sterile marking pen (included) to identify the four quadrants of the cornea for cardinal suture alignment; one time use only; 1 each to a package
A surgical item which removes a circular piece from the cornea. It is used with a spring-loaded syringe connected to a vacuum chamber, which allows this to be attached to the cornea. This holds the patient's sight in a more natural state during trephining corneal transplant procedures.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
No known electrostatic discharge (esd) or electromagnetic interference (emi) sensitivity.
Represents items with no adp components

HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
