摘要：
In one aspect, the present invention provides anoph-thalmic lens (e g, an IOL) that includes an optic having an anteriorsurface and a posterior surface disposed about an optical axis At leastone of the surfaces (e g, the anterior surface) has a profilecharacter-ized by superposition of a base profile and an auxiliary profile Theauxiliary profile can include an inner region, an outer region and atransition region between the inner and the outer regions, where anoptical path difference across the transtion region (i e, the opticalpath difference between the inner and the outer radial boundaries ofthe transition region) corresponds to a non-integer fraction (e g, 1/2)of a design wavelength (e g , a wavelength of about 550 nm)
