jj, I had cataracts removed about five eyars ago. I don't know if it was by laser or not as I requested a general anaesthetic (no way do I want to be in the same room as someone messing with my eyes). But last year's was just a minor adjustment as my vision seemed to be weakening slightly. It was basically sitting with my chin resting on a machine like they use in eye tests while he fiddled with a bright light. I didn't feel a thing.
I'm just assuming removal of cataracts is a more major job than the little adjustment (which seems to have worked).
I was alerted to both of these by Specsavers, who then notified my GP that I needed work done; it was done on the NHS both times.
