OPHTHALMIC DEVICES FOR HYDROPHOBIC COMFORT-MAINTAINING AGENT DELIVERY Russian patent published in 2014 - IPC B29D11/00 C07F7/02 C08G77/00 G02B1/04 

Abstract RU 2527976 C2

FIELD: medicine.

SUBSTANCE: invention refers to ophthalmic devices and methods for preparing them. What is presented is a soft silicone hydrogel contact lens which possesses an ability to deliver a hydrophobic comfort-maintaining agent (phospholipid, glycolipid, glyceroglycolipid, sphingolipid, sphingoglycolipid, fatty alcohol containing 8 to 36 carbon atoms, or a mixture thereof) into the user's eye gradually releasing it from a polymer matrix consisting of hydrophobic chains formed of a silicon monomer or macromere, and hydrophilic chains formed of a hydrophilic monomer or macromere when in use. What is also presented is a method for making the above contact lens.

EFFECT: in the presented soft silicone contact lens, the hydrophobic comfort-maintaining agent is not covalently bond to the polymer matrix wherein it is distributed and can be released from the soft hydrogel contact lens into the user's eye when in use reliably for a long period of time and thereby reinforcing and stabilising a lipid layer of the lachrymal fluid film and reducing eye dryness.
