Method for applying a coating onto a silicone hydrogel lens
Abstract:
The present invention generally relates to a method for applying a coating of hydrophilic polymers onto silicone hydrogel contact lenses to improve hydrophilicity and lubricity. In particular, the present invention is directed to a method for forming a coating on a contact lens, preferably a silicone hydrogel contact lens, directly in the primary package and maintaining the coated contact lens within said primary package until insertion of the coated contact lens in the eye of the contact lens user. The resultant silicone hydrogel contact lens has a coating with good hydrophilicity, improved lubricity and good durability and also can be used directly from the lens package by a patient without washing and/or rising.
