Japan Atomic Energy Research Institute, Christensen O Connor Johnson & Kindness, October 29, 1991: US05061057 (3 worldwide citation)

In order to make hard and soft contact lenses having a pore diameter and a pore density optimum for use as oxygen permeable contact lenses, the contact lens after molding is subjected to irradiation of a polyvalent heavy ion beam having a mass number of 2 to 100 (preferably 10 to 80) and an ion ener ...
