Accommodating intraocular lens to restore vision lost by presbyopia

Research

Presbyopia affects 100% of the population over 45 years old. Moreover, 70% of the population will develop cataracts after the age of 70.

Aim

  • To restore the accommodating capability of the crystalline lens, lost with presbyopia, therefore restoring dynamic and clear vision, both near and at a distance. Also, to improve the quality of life in the aging population, eliminating the use of glasses.

Problem to Solve

Presbyopia and cataracts are age-related visual conditions that invariably affect everyone beyond a certain age. Presbyopia occurs after age 45, when the crystalline lens loses elasticity and the capacity to dynamically focus, affecting 1.3 billion worldwide. Every year more than 28 million people undergo cataract surgery, whereby the natural lens is replaced with an artificial lens. Intraocular lenses (IOLs) have evolved to eliminate opacification, correct refraction, and provide some functional near vision (multifocal IOLs). However, there is no working solution that provides patients with the dynamic focusing of the young crystalline lens.

Innovation

The VioBioLab has developed and experimentally demonstrated LightLens, a surface reshaping Accommodating Intraocular Lens (AIOL). LightLens is inspired by the natural accommodation mechanism of the eye and is enabled by photobonding, a new method to capture the available forces from the ciliary muscle. Such developments are needed to revolutionize the treatment of presbyopia and cataracts.
