Systems and methods for providing enhanced image quality across a wide and extended range of foci encompass vision treatment techniques and ophthalmic lenses such as contact lenses and intraocular lenses (IOLs). Exemplary IOL optics can include a circular surface structure which acts as a diffractive or phase shifting profile. In some cases, a single ring IOL includes an anterior face and a posterior face, where a profile can be imposed on the anterior or posterior surface or face. The profile can have an inner portion such as a microstructure or central echelette, and an outer portion. Between the inner portion and the outer portion, there may be a transition zone that connects the inner and outer portions.
