Cataracts are the leading cause of preventable blindness worldwide, and intraocular lens (IOL) implantation is the standard treatment following cataract surgery. However, conventional IOLs cannot fully replicate the optical performance of the natural crystalline lens, limiting visual quality and patient outcomes. VISION3D will transform IOL design and manufacturing by harnessing holographic volumetric 3D printing to produce next-generation lenses with enhanced optical functionality. Enabled by Ireland's first Xolo Xube system, the project will establish a new manufacturing paradigm for high-performance ophthalmic devices.
The project will develop innovative fabrication methods for multifocal IOLs incorporating gradient refractive index (GRIN) profiles and diffractive optical structures. By precisely controlling polymerisation during printing, VISION3D will spatially modulate refractive index to more closely mimic the optics of the natural lens. Optical characterisation data will be integrated into an AI-driven design framework that predicts optimal printing parameters, enabling rapid optimisation of lens performance while reducing development time and manufacturing costs. This combination of advanced photonic manufacturing, artificial intelligence and biomedical engineering represents a step change in ophthalmic device development.
Working closely with industrial partners, including global ophthalmic leader Alcon, the project will ensure alignment with clinical and regulatory requirements while accelerating the pathway to commercialisation. Expected outcomes include a proof-of-concept 3D-printed multifocal IOL, an AI-enabled design and manufacturing platform, and a scalable workflow for next-generation ophthalmic devices. Beyond cataract treatment, the technology has the potential to establish a new class of precision-manufactured optical implants, positioning Ireland at the forefront of advanced medical device innovation.
