Granjura that is effectively what my surgeon did when he operated on my cataracts. In my case this wasn't perfect, because I was so short sighted to begin with but, legally, my eyes, without glasses now meet the standard required for driving, although I do prefer to wear glasses when driving for my own peace of mind - I would hate to have an accident and have even a scintilla of suspicion that my eye sight might have contributed to it. However I do not need glasses for reading and close work -and never will.
It is not as disorientating as you might think as the difference in prescription between the two eyes is not that large. My uncorrected eyes showed a far bigger difference. My left eye was nearly twice as shortsighted as my right(-9 and -5) and the difference now is +/- 2.
Personally, cataracts apart, if I was going to fiddle with my eyes to improve my sight, particularly as an older woman, I would prefer to go down the lens replacement route, which is what a cataract operation is, than have laser treatment. The range of corrective lenses that can be inserted in such an operation is immense and if you develop cataracts after the operation the laser operation will only have been effective for the time between the two operations, which could be as little as a couple of years.
