  Tissue banking alludes to the movement of gathering, stockpiling, handling, and circulation of transplantable human tissues. This industry fills in as a store of disposed of tissue and organs, both legitimately and wrongfully. These organs are here and there taken from criminal bodies or the dead groups of lawbreakers. Some of the time they may come from individuals who kick the bucket in emergency clinics. Whatever they are, every one of the organs are normally taken to a focal tissue bank which at that point discards them as indicated by neighborhood enactment. This interaction of collecting organs happens both when passing. There are numerous elements that decide when organs come from dead bodies. The fundamental one is that the organ must be dead and not yet deteriorating. Numerous organs must be eliminated from individuals who have passed on of sicknesses and ailments as these organs are not, at this point valuable. Some are even too harmed to possibly be helpful any longer. N

  Corneal topographers, more commonly known as Photokeratoscopy, are a non-surgical medical imaging method used in regions such as the U.S., U.K. and Italy among others, for non-intravenous mapping of the corneal surface. Unlike conventional corneal topography, laser peripheral iridotomy is used to treat patients with myopia, hypermetropia, or astigmatism. The procedure involves the insertion of a thin fiber-optic laser into the central area of a cornea called the iris. The resulting corneal flap is used as a guide for treating the affected areas to improve vision. In conventional corneal topographers (x-ray or tomography), light is emitted on the corneal surface from the focused laser beam. As the light passes through the corneal tissue, the irregularities in the corneal surface are observed by reflected light. This image provides information about the internal microcosm and the optical properties of the corneal layer. The main advantage of corneal topographers is that they can pro
