Regaining Sight: Stem Cell Transplants Repair Corneal Damage
2025-03-09
A new clinical trial offers hope for patients with corneal injuries. Scientists have successfully repaired severe corneal damage using a transplant of stem cells from the patients' healthy eyes. The treatment, called cultivated autologous limbal epithelial cells (CALEC), involves harvesting stem cells from the patient's uninjured eye, culturing them in a lab for several weeks, and then transplanting them into the injured eye. An 18-month follow-up showed a 92% success rate, with significant vision improvement in many patients, some even progressing from legally blind to low vision. This breakthrough offers new hope for treating corneal injuries and paves the way for larger-scale clinical trials.
