KEY TAKEAWAY POINTS

Depth of focus extension elongates the focal region to provide a continuous range of vision from distance to intermediate, with some functional performance at near.

Small aperture IOLs increase the depth of focus of the eye, but dramatically reduce the amount of light entering the eye, and consequently are typically only implanted monocularly.

Low add diffractive multifocal IOLs can provide similar acuity to extended depth of focus lenses, but are associated with the same visual disturbances, like halos, that are associated with all diffractive lenses.

Wavefront shaping, a next generation optical principle, such as X-WAVE™ Technology, provides depth of focus extension that utilizes all of the light entering the eye while simultaneously reducing the halos and artifacts associated with diffractive lenses.
