VERFAHREN ZUM MARKIEREN INTRAOKULARER LINSEN |
摘要 |
Nondestructive marking of plastic artificial intraocular lenses for coding purposes. Exposure with ultraviolet radiation of portions of a lens surface forming boundaries of desired coding characters or similar exposure only of areas forming the characters themselves produces a differential in refractive index of the material of the lens wherewith detection and reading of the coding may be accomplished before and/or after intraocular implantation. |
