then u havent done enought research yet. laser surgery attempts to "distort"/ modify the natural form of the cornea to "correct" vision.

there are other vision improvements methods around but with slower improvement rate and much more effort.

its like slimming down.. you do it the easy way by liposuction, or the more time consuming way like exercise and joggings... same goes for vision improvement.

How long u've been using it?try to relax urself.Trust me..i've use it before and it works(its take times too).....use the chart that is provided in the website too.....
If possible try to join their seminar too  but  have to pay lar!!!

here's part of the manual

eer.. i didnt say its good. i've just bought it... whether it can "heal" my eyesight are still to be seen. but it IS clearer when i use it.

kornea tak rata , I think is called astigmatism.
