Abstract: The invention is related to the use of liquid, branch-chained fatty acid esters or hydrocarbons with about 20 to 30 C-atoms in the entire molecule as a surface analgesic and antiphlogistic, as well as the use of triglycerides of saturated fatty acids having 8 to 14 carbon atoms for such purposes.

Abstract: There is described a non-irritating method for obtaining lacrimal fluid in the form of resting secretion, in which a hydrophilic contact lens with a water content of 38% to 85% is brought into contact with the lacrimal fluid, the contact lens absorbing the lacrimal fluid which is then extracted by immersing the contact lens in an extractive solution with a 0.8% to 4% concentration of salts, at least one of which is sodium chloride. The extraction takes place at a temperature of 20.degree. to 24.degree. C., and lasts up to two hours during which the extractive solution is stirred or agitated.
