    摘要: A diffractive multifocal lens is disclosed, comprising an optical element having at least one diffractive surface, the surface profile comprising a plurality of annular concentric zones. The optical thickness of the surface profile changes monotonically with radius within each zone, while a distinct step in optical thickness at the junction between adjacent zones defines a step height. The step heights for respective zones may differ from one zone to another periodically so as to tailor diffraction order efficiencies of the optical element. In one example of a trifocal lens, step heights alternate between two values, the even-numbered step heights being lower than the odd-numbered step heights. By plotting a topographical representation of the diffraction efficiencies resulting from such a surface profile, step heights may be optimized to direct a desired level oflight power into the diffraction orders corresponding to near, intermediate, and distance vision, thereby optimizing the performance of the multifocal lens.

    摘要: The invention features methods of treating visceral pain in humans by administering an effective amount of a 5HTIB or 5HTID receptor agonist, (e.g., a triptan). These methods can be used, for example, to treat a human suffering from visceral pain secondary to an underlying disease of a visceral organ, such as pancreatitis. Visceral pain treatable by the methods of the invention may also be secondary to a disease of the liver, kidney, ovary, uterus, bladder, bowel, stomach, esophagus, duodenum, intestine, colon, spleen, pancreas, appendix, heart, or peritoneum.
