Suggestions preventing hook through the eye of smaller trout

[astael]

I am new to fishing, and have a standard style pole, though I think I will get a fly fishing pole soon. The thing that keeps happening that is really upsetting to me is more often than none when I hook a small trout, the hook goes through their eye...  again I am using regular hooks, not the small fly fishing ones. I am guessing that if I were to use the small types used in fly fishing this would not happen?
And I also have filed off the barbs  from my hooks I don't want to harm the fish I would like to release again.  Any suggestions?

Just unfortunate don't think you can do much to stop hooking fish in certain parts
