ABSTRACT
This chapter is inspired by the US Patent Application 20170071728, Double Accommodating Intraocular Accordion Lens. It is also inspired by the published patent application US020170071728A120170316 (https://www.pat2pdf.org" xmlns:xlink="https://www.w3.org/1999/xlink">pat2pdf.org).
A double-accommodating intraocular lens (DAIOL) axially moves its flexible optic to accommodate and peripherally compresses or decompresses the optic to change its convexity or power, thus simultaneously double accommodating upon contraction or expansion of the ciliary muscles and subsequently the lens capsule. A DAIOL includes a deployable semirigid or elastic haptic assembly and a flexible single optic. It is further composed of three or four ring haptics as well as deployable resilient lazy tongs, attached to a single elastic plate encompassing a flexible optic. Accordingly, the radial compression of the capsular bag by the contraction of the ciliary muscles axially moves and radially compresses the flexible optic in the lens and vice versa upon the radial expansion of the capsular bag, backward axial movement, and decompression of the optic, due to the action of the resilient lazy tongs, for double accommodation.
