  • Patent number: 10010502
    Abstract: A non-degradable topical ocular drug delivery device includes about 0.001% to about 10% w/w of at least one myopia-suppressing agent complexed with an immobile acid within a crosslinked polymer matrix. The cross-linked polymer matrix is configured to deliver the least one myopia-suppressing agent over an extended period of time at a concentration and rate that controls myopia progression while preserving pupillary function and accommodation.

  • Publication number: 20040220089
    Abstract: The present invention relates to 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 a tear film and ocular surface disorder known as keratoconjunctivitis sicca or dry eye syndrome. In general, the preparations of this invention are also effective for the relief of symptoms of eye irritation, such as those caused by dry environmental conditions or by contact lens wear. In accordance with the present invention, the ophthalmic preparation includes a glycoprotein component, similar to that found at the normal human ocular surface and in one exemplary and preferred embodiment, the glycoproteins are derived from mammalian milk, preferably bovine.

  • Patent number: 6281192
    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.
