My younger Brother had his done, last year, I think I'm right in saying laser treatment
is for less severe eye vision and Lasik which is where they actually cut the lens..........
( sorry if your eating your lunch !)
Please note I'm not an eye surgeon or specialist and may have this completely wrong DYOR
Before the op, he had to wear glass's or contact lenses all the time, he could read a newspaper ok, unaided, but anything of distance he needed to use glass's/contacts, but since the op
he can now see for miles unaided, but has to wear glasses to read close up ? but for him the op was 110% successful and he is really pleased with the result
I should perhaps add that he had the Lasik op, and is a health care professional , so it wasn't
a quick decision to have this done, he spent age's researching..................
Hope this is of use, and good luck
