ABSTRACT
This chapter is inspired by US Patent 9,681,945, Double Accommodating Intraocular Accordion Lens. It is also inspired by US000009681945B220170620 (https://www.pat2pdf.org" xmlns:xlink="https://www.w3.org/1999/xlink">pat2pdf.org) or pat9681945.pdf.
A double-accommodating intraocular lens (DAIOL) not only axially moves its flexible optic to accommodate but also peripherally compresses or decompresses the optic to change its convexity or power, thus double accommodating simultaneously upon contraction or expansion of the ciliary muscles and subsequently the lens capsule. The DAIOL includes a deployable semi-rigid or elastic haptic assembly and a flexible single optic. The DAIOL is further composed of three or four ring haptics and three or four deployable resilient lazy tongs, attached to a single elastically flexible 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 radial expansion of the capsular bag, backward axial movement, and decompression of the optic, due to the resilient lazy tongs action, for double accommodation.
