Vision correction surgery has come a long way since then. But it wasn't until this year that I felt comfortable with the state of the art. Think of slicing through a thin layer of an apple but not all the way. Lift up the small slice, take a small bite out of the apple, then lay the cover slice back down in the original position. The slice is then repositioned and the tiny thin line of the cut heals quickly.
Most people can go back to work in a day or so.
The results for astronomy have been fantastic. Whereas I previously could only detect six of the Pleides, I was able to see eight at the last Explore the Stars program. The ten brightest stars in the Pleiades are under 6th magnitude and are in theory visible to the naked eye. However most amateur astronomers can only see six or seven due to the congestion of stars in the cluster. Next month I am going to work real hard and see if I can pick up number nine and ten.
