Scientists injected cells from womans leg into her eyes to help restore her vision: How 'world-first experiment' went & what doctors discovered

Scientists injected mitochondria taken from a womans leg into both of her eyes in an experimental attempt to boost energy production in damaged retinal cells. The treatment triggered temporary pupil responses to light after the injections, but her vision did not show any measurable improvement. The single-patient case suggests the procedure may be safe enough for further investigation, while opening up a potential new avenue for regenerative medicine.
