# EU-Supported Researchers Transform Eye Care with Advanced Digital Models
### By Sofia Sanchez Manzanaro
For 89-year-old Mercedes Alvarez, a resident of Gijón in northern Spain, cataract surgery not only restored her vision; it altered her life. Initially apprehensive due to her age, Alvarez now enjoys the simple pleasure of reading the newspaper each morning, astonished by the clarity of the fine print that she had previously found difficult to read.
“I spent many nights awake, worrying because, at my age, even a minor procedure seemed dangerous,” Alvarez reflects. However, with the encouragement of her doctors and significant improvements in eye care, Alvarez’s experience contributes to the increasing evidence showing that age should not hinder access to innovative medical technologies.
Alvarez is among the over four million individuals in the European Union who have cataract surgery annually, as reported by Eurostat. Her narrative mirrors the achievements of recent EU-funded research projects focused on transforming eye surgeries and vision care through advanced digital modeling and collaborative efforts.

### **Revealing the Mysteries of the Human Eye**
One of these cutting-edge research endeavors is the OBERON project, a four-year initiative set to conclude in 2025. Led by Dr. José Manuel González-Méijome, a prominent authority in optometry and vision science at the University of Minho in Braga, Portugal, OBERON unites scientists and non-academic specialists from eight institutions across Europe, including Belgium, Poland, Switzerland, Spain, the UK, and the Netherlands.
At the core of OBERON’s objective is the development of sophisticated computer models of the human eye. These models simulate the intricate optical and biomechanical characteristics of the eye’s delicate tissues, illuminating how these structures function under both normal and pathological states. The aim? To substantially enhance the safety and accuracy of surgical interventions on one of the body’s most complex and delicate organs.
“The human eye is astonishingly small and intricate,” remarks González-Méijome. “It weighs around 7.5 grams and has a diameter of about 2.3 centimeters, necessitating that surgeons navigate these fragile structures without harming the adjacent layers.”
Historically, eye surgeries, such as cataract extractions, have depended on generalized methods, often utilizing average anatomical models. However, OBERON’s computational simulations pave the way for precision surgeries customized to each patient’s specific anatomy. These innovations allow surgeons to prepare with mathematical precision, ensuring improved outcomes and reducing risks.

### **Transforming Cataract Surgery**
Cataract surgery, the most prevalent medical procedure in the EU, involves the removal of a cloudy natural lens and the insertion of a clear, artificial lens. OBERON’s research allows surgeons to move past a “one-size-fits-all” strategy, utilizing real-time data and personalized digital models to forecast how eye tissues will react to various surgical methods.
The implications extend far beyond cataract surgery. The researchers are also working to prevent or mitigate age-related eye disorders, such as lens malfunctions, which currently necessitate surgical intervention. With Europe’s aging population, preventative strategies like these will be vital in lessening the reliance on invasive procedures and preserving quality of life for millions.

### **A Short-Sighted World**
The OBERON team is not solely concentrating on age-related vision issues. Myopia, or nearsightedness, is increasingly becoming a significant concern, particularly among children in Europe. Recent studies indicate that environmental factors such as excessive screen time and intensive near-work practices (e.g., reading or studying) are contributing to a rapid increase in myopia.
“While we encourage children to pursue their studies, we must also enhance our understanding of how to manage the physical impacts on their developing visual systems,” states González-Méijome.
By incorporating their innovative modeling techniques into optometry and laser surgery, the research team seeks to mitigate the progression of myopia while alleviating its long-term consequences. Potential solutions may involve enhanced contact lenses or surgical approaches that address the underlying biomechanical triggers of excessive eye growth.

### **Where Mathematics Meets Biology**
An earlier EU-funded project, MOLEGRO (2014–2017), highlighted the increasing significance of interdisciplinary research in vision science. Directed by Professor Hrvoje Šikić from the University of Zagreb, Croatia, MOLEGRO produced the world’s first mathematical model of eye lens development. This pioneering effort fused mathematical accuracy with biological understanding to unravel the unique growth processes of the human eye lens.
Šikić explains that the lens develops differently from other tissues: new cells are continuously added throughout life, while older cells remain compressed at the center. “The challenge was to connect the theoretical realm of mathematics with the concrete realities of cell biology,” he describes.
Šikić’s findings influenced contemporary cataract surgery techniques by elucidating how these cellular growth patterns, together with risk factors like UV exposure, contribute to the formation of cataracts.
