On December 7, 2021, the MIOK keratoprosthesis was approved by the NMPA, the Chinese Medicines and Medical Devices Regulatory Authority. The MIOK keratoprosthesis is the world’s first approved artificial cornea that does not require co-implantation of donor corneas. It is of great importance for the 60 million patients with corneal blindness worldwide, since the MIOK keratoprosthesis no longer makes it impossible to restore their vision and thus also relieves the relatives.

Corneal transplantation is one of the most important means of restoring the vision of patients with corneal blindness. However, there is a high risk of corneal transplant failure and postoperative complications, usually due to the complex immunological reactions due to incompatibility of a transplanted organ. Such risks are also unavoidable with other artificial corneas that require the co-implantation of donor corneas. The MIOK keratoprosthesis, an artificial cornea made of 100% non-biological materials and which does not require the co-implantation of donor corneas, is therefore an ideal option for the treatment of patients with corneal blindness.

The MIOK keratoprosthesis is mainly made of clear PMMA plastic with excellent optical properties and tissue compatibility. It is designed to restore sight to patients with corneal blindness by creating a transparent optical path through a clouded cornea in the treated eye.

Thanks to its special design and processing, the MIOK keratoprosthesis offers excellent performance in terms of transparency, translucency and durability, as well as high biocompatibility and ease of use in surgical interventions, allowing it to be quickly integrated into the surrounding tissue. Compared with conventional corneal transplantation and other artificial corneas, MIOK keratoprosthesis does not require co-implantation of donor corneas, which counteracts the global shortage of donor corneas and effectively reduces the risk of serious postoperative complications and immune rejection. In addition, the MIOK keratoprosthesis is indicated for patients with corneal blindness when corneal transplantation has failed or is at high risk of failure, particularly patients with corneal graft failure, corneal scarring/vascularization, chemical/thermal burns, autoimmune diseases (Stevens- Johnson syndrome, pemphigoid, etc.), symblepharon and severely dry eyes, etc. Therefore, MIOK keratoprosthesis enables effective treatment for patients with corneal blindness caused by a wide range of corneal injuries.
