Abstract: Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for providing improved extended depth of focus lenses. Exemplary ophthalmic lenses can include an optic including a diffractive profile including at least one set of echelettes, each echelette of the set having a different width in r-squared space than any other echelette of the set and the at least one set of echelettes repeating at least once upon the optic.

Abstract: A protective encasement or wrap for a pet carrier for helping prevent drafts and to provide water resistance, includes a cover member which can be of one piece of material, that when laid out on a flat surface, and with the animal carrier placed in its center, will wrap around the carrier, overlapping at the carrier top. The ends that overlap at the top, and along the side border each has a cutout for providing for the insertion of a handle of a carrier. The material is sized such that there is sufficient overhang at either end of the carrier to close off either end. A drawstring, or elastic at the ends, when not completely closed, provides an opening into the interior, permitting opening of the carrier door, and insertion of a hand to pet the animal, provides air circulation, insertion of items, or to remove the pet, without the need to remove the wrap.
