FEMTOSECOND LASER MICROMACHINING OF A CONTACT LENS AND A CONTACT LENS MANUFACTURED THEREBY |
摘要 |
<p>A method of providing a feature on a contact lens including applying a femtosecond laser beam to ablate at least a portion of the contact lens to provide the feature on the contact lens. In one embodiment, the femtosecond laser beam has a pulse width between 10x10<SUP>-15 </SUP>seconds and 200x10<SUP>-15 </SUP>seconds, and has a wavelength between 100 nm and 1500 nm. A contact lens is also provided including at least one fenestration fluidically connecting the anterior surface and the posterior surface, the fenestration being formed using a femtosecond laser in a manner that areas surrounding the fenestration are substantially free of heat damage.</p> |
