Breakthrough in ocular device technology could revolutionise treatment for cataracts

An artificial intraocular lens (IOL) is primarily required for people with cataracts, a condition where the eye’s natural lens becomes cloudy, obscuring vision.

They can also be also used to correct refractive errors such as myopia (near-sightedness), hyperopia (far-sightedness) and presbyopia (when eyes gradually lose the ability to see things clearly up close, as a normal part of aging).

“For the first time, we have developed a resin that can be used to print ocular devices directly,” said lead author Dr Aram Saeed, Associate Professor in Healthcare Technologies at UEA's School of Pharmacy, in a statement.

“While still in the early stages, the ability to 3D print these lenses could significantly enhance eye care for patients by offering unprecedented levels of customisation and design precision, potentially leading to better clinical outcomes.”

Historically, IOLs have been made from a variety of materials, including glass and silicone, although more recently the industry has significantly evolved to predominantly use acrylic materials.
