Abstract
A process for making lipid-coated substrates including the steps of a. providing a lipid solution (A) of phospholipids in a water miscible organic solvent at a phospholipid concentration between 25 and 450 mg/ml; b. provide an aqueous solution (B) having pH between 4 and 8; c. agitate the aqueous solution (B) and dispense the lipid solution (A) into the aqueous solution (B) to prepare an aqueous dispersion including lipid vesicles (C) having a number average size between 80 and 120 nm (measured according to dynamic light scattering) at a phospholipid concentration between 0.05 mg/ml and 2 mg/ml; and d. applying the aqueous dispersion (C) to a substrate and formation of a lipid-based coating; wherein aqueous dispersion (C) contains at least 95 wt. % water. Medical devices including a lipid-based coating, for example contact lenses and catheters.
