Abstract:
A process for the preparation of storage-stable hydrogel mouldings which comprises the following steps:a) transferring a hydrogel moulding that contains hydrolytically removable side groups to a container,b) filling up the container containing the hydrogel moulding with a basic buffer solution,c) closing the container, ande) autoclaving the container containing the hydrogel moulding and the basic buffer solution at a temperature of at least 100.degree. C.,wherein, during the autoclaving, the hydrolytically removable side groups are essentially completely removed, the container contents are sterilised, and the basic buffer solution is converted into a physiologically acceptable aqueous solution that is substantially isotonic and pH-compatible with the lacrimal fluid of the human eye.
