[Repair of corneal defects using tissue engineering].

Area of Science:

• Ophthalmology
• Regenerative Medicine
• Biomaterials Science

Context:

• Deep corneal burns cause significant vision loss due to keratocyte death and stromal destruction.
• Current treatments for severe corneal damage have limitations in restoring tissue integrity and transparency.
• The need for advanced therapeutic strategies to address severe ocular surface disease is critical.

Purpose:

• To develop and evaluate a novel therapeutic approach for deep corneal burns using a living stromal equivalent graft.
• To assess the efficacy and safety of this regenerative treatment in patients with severe corneal defects.
• To investigate the potential of restoring corneal structure and function through bioengineered tissue grafting.

Summary:

• A technique for isolating and grafting a living stromal equivalent was developed and applied to 21 patients with deep corneal defects.
• The treatment demonstrated a stable therapeutic effect in 95% of the treated patients.
• A key advantage observed was the partial recovery of corneal transparency in the affected eyes.

Impact:

• This living stromal equivalent grafting offers a promising therapeutic option for deep corneal burns, potentially improving visual outcomes.
• The study highlights the potential of regenerative medicine in treating severe ocular injuries.
• Successful partial restoration of corneal transparency suggests a viable alternative to traditional corneal transplantation for certain conditions.
