ИСТИНА

The cornea is of the great importance among the other eye refractive structures. The cornea maintains the most eye’s refractive power and provides the visual function. The clarity of corneal tissue is vitally important for this function and strongly dependent on its tissue hydration level. This level is regulated by internal eye mechanisms and in the most cases varies from 78% to 80% by volume. The change of hydration level even for a few percents may indicate various possible corneal diseases related to the restructuring and swelling of the various cornea layers, tear film and epithelium / endothelial integrity.
