Saffie Sandford from Stevenage in Hertfordshire was diagnosed with Leber's Congenital Amaurosis (LCA), a rare inherited condition that inhibits the production of proteins essential for normal vision, according to multiple reports. The specific gene therapy used has not been disclosed, nor has the exact date of treatment. The extent of Saffie's vision loss before the procedure and any potential side effects or long-term outcomes remain unknown.
It is also unclear how many other children have received this therapy on the NHS.
