The document discusses the Synchrony Dual-Optic IOL, an accommodating intraocular lens. It has a single-piece design with a +32D anterior optic and a variable negative posterior optic connected by spring haptics. When the ciliary body contracts, the anterior lens moves forward to change focus for near and intermediate vision. Key features include aqueous channels, a tenting design, posterior wings for positioning, and spacers to prevent adhesion.
