Verfahren zur Befestigung einer Haptik mit dem optischem Teil einer Intraokularlinse.

摘要

A method for attaching a polymethylmethacrylate haptic (20) having a colored core to an optic (10) of an intraocular lens, containing the steps of providing the periphery of the optic with a pair of intersecting holes (303,304), inserting an end of the haptic (20) into one hole (303), inserting an end of an polymethylmethacrylate anchor strand (25) having a colored core into the second hole (304) so that the end of the anchor strand and the end of the haptic (20) intersect, aiming a laser capable of a transmitting energy of a visible wavelength at the intersection of the first and second holes (303,304), firing the laser through the optic at the point of intersection of the end of the haptic (20) and the end of the anchor strand (25), wherein the optic transmits, but essentially does not absorb, the laser energy and the core of the anchor strand (25) and the core of the haptic (20) absorb a portion of the laser energy sufficient to fuse the end of the anchor strand and the end of the haptic at their point of intersection.
