The lens is unique in that it is designed to change its true power during accommodation rather than changing its position in the eye.
Current single- and dual-optic accommodative IOLs work through pseudoaccommodative mechanisms. These mechanisms involve a forward axial movement of the optic or one of the optics (dual-optic design) during accommodative effort, which has the ultimate result of increasing the effective power of the lens in relation to its pre-accommodative position. This relative increase in effective power results in induced myopia during accommodation and improved ability for near activities.
