DYNAMIC RANGE OF FOCUS (DRoF), or the total range of clear vision in a natural system, is an important biomechanical function of the accommodative apparatus responsible for adjusting the crystalline lens from both far to near (accommodation) and near to far (disaccommodation). DRoF is defined by true accommodation, pseudoaccommodation, and pupillary diaphragmatic changes, which work together …

What other future treatments have promise? Laser scleral microporation is under investigation as a laser treatment for patients with emmetropic presbyopia. Four quadrants of the sclera are treated with an Er:YAG laser to uncrosslink the sclera and rejuvenate the accommodative mechanism (see video demonstration below). Treatment does not appear to affect the visual axis or …
