<p>Carboxymethylcellulose binds to the surface of corneal epithelial cells via its glucopyranose subunits binding to glucose receptors GLUT-1. The residence time of carboxymethylcellulose bound to corneal cells is approximately 2 hours as indicated by a short-term binding assay. Binding of carboxymethylcellulose to the matrix proteins stimulated corneal epithelial cell attachment, migration, and re-epithelialization of corneal wounds.<br />

This eye drop contains Carboxymethylcellulose Sodium similar to normal tears which acts as an ocular lubricant. It provides a lubricating and hydrating protective shield on the ocular surface.</p>
