Ocular Health Implications of the Loss of Dynamic Range of Focus Function in Presbyopia
Presbyopia is defined as the eye’s loss of ability to focus on objects at near distances, and it is the most common cause of age-related vision impairment. Presbyopia is a significant global health issue that is underdiagnosed. It affects all people in their 40s and older: an estimated 90 million people in the United States and more than 1 billion people worldwide, are affected.1 Of these, half a billion have no or inadequate spectacles, and 410 million are unable to perform important near tasks.1–3 Thus, presbyopia is both widespread and undertreated.

ASCRS 2025: AnnMarie Hipsley, DPT, PhD, presents AI-driven digital twin for simulation of aging eye
The Virtual Eye Simulation Analyzer is an AI-driven digital twin of the human eye designed to model aging and personalize presbyopia treatment across the lifecycle. AnnMarie Hipsley, DPT, PhD, presented a transformative concept in ophthalmic innovation: the “digital twin” of the human eye, embodied in the Virtual Eye Simulation Analyzer (VESA)—a virtual, AI-driven model capable …

CARLSBAD, Calif. — In this Healio Video Perspective from the Women in Ophthalmology Summer Symposium, Dagny Zhu, MD, and AnnMarie Hipsley, DPT, PhD, discuss laser scleral microporation for presbyopia. Hipsley said it is important to understand that presbyopia is an aging disease rather than a refractive disorder. Catching it early and treating it can be beneficial for patients. Zhu said laser …

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 …
