I used to be able to focus my 28x110 binocular at 100m distance before lasik. After lasik, I cannot focus anymore as I have turned the knob to the extreme already. Anyone recommend me a way to fix this problem?
If I understand this right, you run out of close focus after lasik at 100m. You can still focus at longer distance.
What was your old eye lens prescription? Do you still have your old glasses, try them. I might be thinking backwards on this.

As far as I can see, there are only two possible reasons that you cannot focus them anymore:
1) The binoculars have become faulty
2) Your eye surgery has made you hyperopic, I assume you were myopic before.
If you went through the treatment recently, the corneae need some time to stabilize, and hopefully the blur will cease.
100 meters at 28x equals 3.6 meters with the naked eye. Do you find your TV set sharp at that distance?
