Many thanks. Does this mean that -2.75 without astimatism (my left eye) will be enough for me not to need reading glasses after my second operation even if I go for say, -1.75 in the next operation. Of course right now I am too unbalanced (right eye is -5.5 and left eye is -2.75). When I am less unbalanced (say at -2.75 in left and -1.75 in right) will I be able to read well without glasses? Right now it does not matter which eye I close, I still cannot read well with the other unclosed eye!
Most people chose to go the other way with the second eye. That is to leave is LESS than -2.75 planning a refraction of -1.50 to -1.75 would allow you to read with the first operated eye and with the second one to see the computer, shave or apply make up and shop all without glasses.
