Innovative resin for 3D printing intraocular lens (IOL) devices, developed by University of East Anglia researchers, could revolutionize cataract and refractive surgeries. This breakthrough enhances the production of eye implants, which are essential for people with cataracts whose natural lenses have clouded, affecting vision.
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.
Currently hydrophilic and hydrophobic acrylic are the most commonly used materials due to their excellent optical clarity, flexibility, biocompatibility with the body and for their stability and safety within the eye.
Current methods of making IOLs use lathing and molding techniques. While these methods offer the production of well-engineered and high-optical quality devices, they also come with inherent limitations, particularly in terms of design complexity and customisation.
Dr. Aram Saeed said: “3D printing could significantly enhance the production of ocular devices, not only improving speed and precision in manufacturing but also enabling greater complexity and customization in design. Our proof-of-concept paper is the first in a series that will detail our developments in this area and set the stage for transforming eye care practices globally. Our work combines material science with healthcare technology and requires extensive know-how in developing these types of ocular devices. As we continue to publish our findings and share our advancements, we aim to be at the forefront of the industry, working with industrial partners and researchers worldwide to refine and enhance the technology.”
The study found that the 3D-printed lenses have good optical clarity, can be folded, and can be implanted into a human capsular bag.
Co-author Michael Wormstone, Emeritus Professor at UEA’s School of Biological Sciences, said: “If successful in further developments, this new technology could transform the industry by enabling portable manufacturing solutions, especially beneficial in remote and economically disadvantaged areas. It also has the potential to support the production of premium, customized lenses that could enhance surgical outcomes in more advanced healthcare settings.”
The team’s efforts have been recognized with the awarding of a United States patent assigned to UEA Enterprise Limited, a business entity of the university focused on fostering innovation and commercializing research.
The UEA researchers continue to work closely with industry partners to refine the technology. It is hoped that clinical trials could start in the next few years.
