Abstract: The invention provides a method producing contact lenses, comprising the step of: separating the mold into the male and female mold halves, with the silicone hydrogel contact lens adhered on one of the male and female mold halves; bring a shaped ultrasonic horn in direct contact with at least one area of a non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon; and applying a ultrasonic vibrational energy to the at least one area of the non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon so as to separate the molded silicone hydrogel contact lens from the mold half attached thereon.

Abstract: Certain embodiments provide an intraocular lens (IOL) including a lens body having an anterior lens element and a posterior lens element, and an optical fluid in a cavity formed between the anterior lens element and the posterior lens element. The anterior lens element and the posterior lens element each comprise a lens material having a first Abbe number, and the optical fluid has a second Abbe number that is less than the first Abbe number.

Abstract: Certain aspects provide an intraocular lens (IOL) including a monolithic lens body having an anterior nanostructure assembly on an anterior outer surface of the monolithic lens body and a posterior nanostructure assembly on a posterior outer surface of the monolithic lens body, and one or more haptics coupled to the monolithic lens body.
