Patient’s own mitochondria injected into eyes in attempt to restore vision

TL;DR - Researchers injected patients’ own mitochondria into the retina in an attempt to restore vision. The procedure appeared safe, but any visual improvement was temporary.

• The treatment used autologous mitochondria, meaning they came from the patient.
• Mitochondria were delivered directly into the retina.
• The reported effect on vision was temporary rather than sustained.
• The limited information provided does not specify the trial size, condition treated, or magnitude of improvement.
