What do I need to know before getting laser eye surgery?

Over deze aflevering

Shortsightedness or myopia affects long distance vision, preventing people from seeing objects over a few yards away. You may remember we covered the subject on Do You Really Know? a while back and that it has been labelled an epidemic due to ever increasing prevalence worldwide. It’s estimated that a third of all people suffer from myopia, and the World Health Organisation has suggested that half of all human beings in the world will be shortsighted by 2050, with excessive screen use and a lack of time spent outdoors largely to blame. If you simply can't stand contacts or glasses, laser surgery is another option. It's been in fashion since the turn of the century and according to Optegra, over 15,000 Brits choose to go down that route each year. Can all shortsighted people get laser eye surgery?
