SP 3000
The SP 3000 is a Specular Microscope, which uses a technique based on projecting a narrow beam of light onto the cornea, with a certain angle of incidence; A small fraction of the light is reflected at the interface between corneal endothelium and the aqueous humor, as if it were a mirror, and is collected by the microscope objective, forming an amplified image of the area. On this image, a computer program analyzes the cells, in their shape, size, distribution and quantity per unit surface.
The endothelial cell count is a test that allows the assessment of the density, size and shape of endothelial cells. Endothelial cells are the cells that form the deepest layer of the cornea, known as the endothelium. It is the innermost layer of the cornea, in contact with the aqueous humor, and is made up of very fine flat cells, arranged in a mosaic pattern. Its mission is essential to keep the cornea completely dry. That is the condition for it to be transparent. It acts as a pumping system so that water molecules always pass from the cornea to the aqueous humor and not the other way around. The variations in the density, shape or size of the cells that can be seen thanks to this test help us diagnose different corneal pathologies, whether dystrophies or degenerations, and to make a pre- and post-operative assessment, among other uses.
