  Description
Glycerin Eye Drop / PEG 400 and Propylene Glycol Eye Drop One eye will randomly receive a single instillation of one drop of a new formulation of an artificial tear containing glycerin 1% as an active with polylysine-graft-polyethylene glycol as an excipient. The other eye will receive a single instillation of one drop of an artificial tear with propylene glycol (0.3%) and polyethylene glycol (0.4%) as active ingredients with hydroxypropyl-guar as a gelling agent.
