Hayom, Israel, reports that a 78-year-old legally blind is the first patient to regain his vision after receiving a new corneal implant. developed by a company called CorNeat, KPro is the first implant that can be integrated directly into the eye wall, replacing scarred or deformed corneas without any donor tissue. Immediately after the procedure, patients are able to identify Family members and read numbers on their vision chart.

The Cornea is the clear layer that covers and protects the front of the eye. It can degenerate or be scarred for a variety of reasons, including diseases such as pseudophakic macular keratopathy, cone corneas and trauma.

Artificial corneal implants already exist in patients with corneal degeneration, but because of the complexity of the procedure, they are often a last resort when grafts or corneal ring implants don’t work. In contrast, inserting a CorNeat graft is a relatively simple procedure that requires minimal suturing and cutting, according to CorNeat. Most importantly, it uses bionic materials to “stimulate cell proliferation, leading to progressive tissue integration.

CorNeat added, “Fibroblasts and collagen gradually form next to each other and achieve full integration within a few weeks, permanently embedding the device in the patient’s eye. “This improves visual acuity and “unusually fast recovery Time ” and looks natural.

The company even said that 10 more patients have been approved for trials in Israel. It plans to open two more in Canada this month, with six more in France, the U.S. and the Netherlands in the approval process. Although the implant does not contain any electronics, it could help more people than any robotic eye.

After years of hard work, it was exhilarating and emotional to see a colleague easily implanted with the CorNeat KPro and to see his vision return the next day,” said Dr. Gilad Litvin, co-founder of CorNeat Vision. , and the room was filled with tears. “
