摘要:
A foldable lens comprises an outer refractive surface portion comprising a first plurality of convexly curved refractive profile regions having positive optical power to converge light energy with refraction toward a focus on the retina. The convexly curved refractive profile regions of the outer region may correspond to at least about a quarter of the refractive power of the lens, such that the lens thickness is decreased substantially and the folded lens can fit through a small incision. The outer refractive surface portion focuses light with refraction, in focus images viewed through the outer portion of the lens can appear sharp to the patient. The outer refractive surface portion also comprises a second plurality of concavely curved refractive profile regions having negative optical power disposed between the first plurality, so as to diverge the light energy substantially away from the focus on the retina, such that visual artifacts are inhibited.
