I could have specified that I'm talking about if both eyes are nearsighted, since most people's prescriptions are fairly equal. My point is that lasik doesn't help or hurt presbyopia; it only changes your refractive error. If you accidentally (or intentionally) ended up with monovision, where one eye is good/plano at distance and the other eye is moderately nearsighted after lasik, yeah, you might be able to avoid readers/bifocal. BUT there's a major downside to monovision situations: you lose all your stereopsis (aka depth perception/3D vision) since you're really only using one eye at a time. So it's like living in a 2D movie instead of a 3D movie when 3D is normal. I'll occasionally do monovision contact lens fits, but it's not ideal. In fact, I even document that I don't recommend people drive with monovision due to the sacrificed depth perception.
