The Mayo stand is used to hold instruments that are used frequently during the procedure. It is draped with a bacterial barrier, and the placed directly over, but not in contract with, the patient once the patient drapes are applied. It is adjustable in height, and is totally portable, since it moves on wheels.

The microkeratome blade is reusable and is made up of sapphire. It is used for the removal of the epithelial layer and underlying basement membrane while leaving a smooth and undisturbed bowman's membrane in preparation for a laser refractive surgical procedure. The blade is capable of cutting through the epithelial layer and basement membrane, but not capable of cutting through bowman's membrane.

The Maddox rod is a device used in the diagnosis of extraocular muscle imbalance. It consists of a series of powerful convex cylindrical lenses mounted side by side in a trial lens. The patient views a distant white point source of light through the Maddox rod, which is placed close to the eye. It consists of a row of such cylinders, and thus a row of foci are formed on the retina. These foci join up and are seen as a line of light, which lies at 90° to the axis of the Maddox rod.

Manual refractor is a set of lenses of various dioptric powers intended to measure the refractive error of the eye.

Medpor sheet implants are commonly used for orbital floor reconstruction and other craniofacial applications. It is designed to provide the surgeon with greater flexibility and to provide a smoother surface for easy insertion into the orbit. It is ideally suited for the repair of small orbital fractures.

Magnesium is an essential mineral for human nutrition. Magnesium in the body serves several important metabolic functions. It plays a role in the production and transport of energy. It is also important for the contraction and relaxation of muscles. It is involved in the synthesis of protein, and assists in the functioning of certain enzymes in the body.

Microbial detection system is a non-radiometric, colorimetric system consisting of a culture bottle with a growth sensor for detecting mycobacterial growth. This instrument incubates and scans the bottles for positivity and a computerized data management system records and reports results. The MB/BacT susceptibility test is performed using the MB/BacT process bottles, MB/BacT antibiotic supplement reconstitution fluid and antimicrobial drugs.

A micro curette consists of an indented scoop with sharp edges. It is used for scraping or cleaning. It can also be used for separating and transporting, inoculating plates, or transferring small amounts of chemicals.

Micro recording system is designed for functional neurosurgery centers investigating and treating single- and multi-target movement disorders. Its versatile capabilities provide support for the use of up to ten microelectrodes simultaneously. An additional four auxiliary analog input channels and two auxiliary digital input channels are also available. Each microelectrode channel features optimized analog signal conditioning circuitry and a dedicated high speed digital signal processor allowing sophisticated real time analysis of the microelectrode signal.
