I’m also going to have this surgery at some later time, basically I was told that it’s a very common procedure and you’re awake, they can do it manually which the government usually pays for but you have to pay for new lenses that go into your eyes. The other option is having laser surgery which is probably easier but not covered by the government and less messy, they will also provide you with paperwork that will answer all your concerns, it’s a common procedure and occurs more often with seniors.
