Abstract:

Wettable surfaces of a permanent nature can be produced on contact lenses by means of the technic of chemical deposition of an inorganic film on the lens surface. The process is simpler, both in apparatus and procedure, than the vacuum deposition technic designed earlier for producing wettable surfaces on plastic lenses the new process should have wide application. This report summarizes the factors involved in the process of coating a polymethyl methacrylate substrate with a thin film of titanium dioxide which has the properties desired-that is, transparency, wettability, adhesion, and immersion resistance. Stepwise instructions are given for the preparation of hydrophilic surfaces on contact lenses. The equipment developed for this work is relatively simple and inexpensive. Author
