Abstract
The present invention discloses the ophthalmic applications of mucin derived from mammalian milk or milk byproducts. This mucin has been found to be a MUC1 type mucin similar to the transmembrane mucin expressed on the surface of the human eye. The mucin-containing preparations described in this invention can be in the form of an aqueous formulation to be instilled into the eye, or in which to pre-soak or store an object to be inserted into the eye, such as a contact lens, an ointment, or a solid device to be inserted into the conjunctival sac. The preparations disclosed are utilized for the treatment of tear film and ocular surface disorders associated with the signs and symptoms of dry eye. Furthermore, mucin-based formulations are also effective for the relief of symptoms of eye irritation, such as those caused by environmental conditions or by contact lens wear.
