3D Printing Strategies for Bioengineering Human Cornea

Over 4.2 million people worldwide suffer from vision impairment related to corneal diseases due to a shortage of donor corneas.

• 3D printing may offer a viable solution for corneal tissue engineering by providing precise control over structure and cell interactions.
• The choice of biomaterials and printing methods is critical for achieving desired properties in 3D-printed corneal constructs.
• Current research has not adequately addressed cornea-specific benchmarks such as transparency, curvature, and mechanical strength.
• Advancements in 3D bioprinting technologies could enable the production of multilayered corneal constructs with enhanced features.
• 3D printing is associated with the potential to create scalable solutions to address the global shortage of donor corneas.
