Robot saved my sight by blasting my eye with radiotherapy

Every month for more than a year, company chairman Michael Edwards went to a hospital miles from his home to have an injection into his eyeball. The treatment was painful and often inconvenient -- but he endured it for 15 months because it was saving his sight. 'However, while my sight didn't worsen, it didn't make any improvement,' says Michael. 'I still couldn't read.' Yet now, thanks to a robot and the type of treatment usually used for cancer, he can see more clearly -- and the same technique could one day improve the lives of countless others. Sixteen months ago, Michael, from Fawsley in Northamptonshire, was diagnosed with age-related macular degeneration (AMD), a leading cause of blindness in the over-60s.
