FIELD: ophthalmology.
SUBSTANCE: invention relates to an ophthalmic product. An ophthalmic product that comprises a sealed and autoclaved lens package containing (1) an autoclaved packaging solution containing a polymeric surfactant having an HLB value of about 11 to about 16 and a Mn of about 800 to about 20,000 dalton, and (2) an easy-to-use silicone hydrogel (SiHy) contact lens immersed in the packaging solution is provided.
EFFECT: easy-to-use SiHy contact lens contains a polymeric surfactant that provides excellent wettability of the easy-to-use SiHy contact lens immediately after opening the lens package, as well as a leachable polymeric surfactant that is physically dispersed in the polymer matrix of the SiHy contact lens and which can be released into the patient's eye for at least 7 days of daily wear; and replenish the polymeric surfactant associated with the lens surface to provide sustained wettability of the contact lens and the eye.
