🧬 A 3D-printed retina is bringing sight restoration one step closer Imagine a tiny artificial retina that can actually mimic the complex layers of the human eye. That is exactly what researchers in South Korea are working toward. Scientists at POSTECH and partner institutions have created a 3D-bioprinted retina-on-a-chip using specialized retinal bioink. The model contains both blood-vessel and nerve-like layers, allowing researchers to recreate retinal vein occlusion — a condition that can lead to severe and irreversible vision loss. But there’s an important detail hidden behind the viral headlines… 🚫 They have not printed an entire human eye or restored sight in a blind patient. Instead, they have created a sophisticated laboratory model that behaves more like real retinal tissue. This could give scientists a powerful new way to study eye diseases and test potential treatments before moving to human trials. And that may be the most exciting part. Today, damaged retinal tissue is extremely difficult to repair. Tomorrow, technologies like this could help scientists understand how to replace, repair, or regenerate the cells responsible for vision. We’re not at artificial sight yet — but the road toward regenerative eye medicine is becoming much more real. Source: Postech, & partner institutions.
