ABSTRACT An intraocular lens loop, with an eyelet formed on the loop, and a method of forming the eyelet employing ultrasound energy. There is also disclosed a special fixture for use in manufacturing the eyelet loop. In the present invention, loop material is formed into a desired shape with a portion of the material coiled in overlapping relationship providing an overlapping portion and an overlapped portion of the loop to form an eyelet wherein the confronting surfaces of the overlapped loop material define an overlapped region for providing a bonding site. At least the overlapped region of the loop is placed on an anvil of an ultrasonic bonder where it is contacted with the horn of the bonder. The overlapped region is compressed with the horn so that the resulting thickness of the compressed overlapped region is not less than the thickness of the loop material in the region of the loop that is not overlapped. The ultra- sonic bonder is then energized to bond the confronting surface of the overlapped region.
