Abstract
A method of modifying a surface of an ophthalmic lens, includes the steps of: generating plasma at an atmospheric pressure between electrodes of a plasma generating device; and blowing the plasma from the plasma generating device by introducing a gas between the electrodes. The ophthalmic lens, which is located outside the plasma generating device, is irradiated with the plasma blown out from the plasma generating device to modify the surface of the ophthalmic lens to form a final ophthalmic lens product.
Claims31
A method of modifying a surface of an ophthalmic lens, comprising the steps of:
- positioning said ophthalmic lens in a flexible lens holder;
- generating plasma at an atmospheric pressure;
- and
- contacting said ophthalmic lens while positioned within said flexible lens holder with said plasma to modify the surface of said ophthalmic lens to form a final ophthalmic lens product.
A method of modifying a surface of an ophthalmic lens, comprising the steps of:
- generating plasma at an atmospheric pressure between electrodes of a plasma generating device;
- and
- blowing said plasma from said plasma generating device by introducing a gas between said electrodes, so as to irradiate said ophthalmic lens located in an ambient atmosphere outside said plasma generating device with said plasma blown out from said plasma generating device to modify the surface of said ophthalmic lens.
