• Tissue Engineering

Background:

• Corneal blindness is a major global health issue, limited by donor tissue availability and inadequate in vitro models.
• Current treatment options for corneal blindness are insufficient due to these limitations.

Purpose of the Study:

• To review the current status of cornea chip technology for modeling the human cornea.
• To identify challenges and future directions in developing advanced cornea in vitro models.

Main Methods:

• Analysis of recent advancements in biomaterials and fabrication techniques for cornea chips.
• Examination of current cornea chip designs, their applications, and limitations.
• Exploration of strategies to overcome challenges like corneal curvature and basement membrane formation.

Main Results:

• Cornea chips show potential for revolutionizing ocular research, offering predictive models for drug screening and disease study.
• Existing models are being improved to better recapitulate corneal structure and function.
• Key challenges include replicating native corneal architecture, curvature, and innervation.

Conclusions:

• Cornea chips hold significant promise for accelerating therapeutic development for corneal diseases.
• Future directions involve incorporating corneal curvature, using patient-derived cells, and developing comprehensive disease models.
• These advanced models can reduce reliance on animal testing and improve personalized medicine approaches.
