Summary

Participants will be invited to participate in this clinical study because they have a severe corneal melting. An eye disease characterized by the progressive loss of the transparent tissue that covers the eye (the cornea). This condition can cause pain, vision loss, and risk of eye perforation. Furthermore, in some cases, the response to standard treatments is inadequate. A piece of 3D-printed human collagen will be implanted on the affected surface of the eye in order to reinforce and protect it and prevent its progression to perforation. The collagen piece is biocompatible, flexible, and transparent, designed to integrate naturally with the eye's tissues. Since it does not require a complete transplant or a human donor at the time of surgery, it reduces the risks of rejection and complications associated with other more invasive techniques.

Detailed description

The 3D-printed collagen will be used in clinical research as a biocompatible graft for the treatment of severe corneal melting, providing structural support and promoting epithelial regeneration without the need for more invasive transplants.

Conditions

• Patients With Severe Corneal Melting

Interventions

Type	Name	Description
DEVICE	3D collagen implant printed under GMP conditions.	Given its exploratory nature, the study does not propose an equivalence threshold compared to standard treatments, but rather seeks to confirm the safety and clinical viability of the implant. It is expected that 3D-printed collagen will provide superior stromal support, with greater transparency and stability than other reconstructive techniques, such as amniotic membrane, conjunctival flaps, or tectonic grafts.
