A research team sent 135 artificial lenses without packaging to the International Space Station, where they remained for about six months exposed to low Earth orbit conditions before returning for analysis. The study's goal is to test how these eye implants withstand extreme space conditions, which is relevant for future Mars missions. Space radiation and the absence of an atmosphere represent significant challenges for the materials used in medical implants. The results of this research could inform the development of more resilient eye implants for astronauts on long space missions.
