To put things in perspective, when patients have been thoroughly checked and found to be suitable for LASIK, regression is an unusual thing to happen. And even if it happens, such regression is of a low degree, and is often low enough that glasses are usually not necessary.
The best method to prevent regression? This is to make sure the spectacle power is stable before going for the refractive surgery. It is also the reason why such surgery as LASIK is not performed on children, because their spectacle power is almost always not stable yet.
Besides this, there isn't really anything that you could say is proven beyond doubt in large studies to be particularly effective in preventing regression.
Perhaps for those at higher risk of regression, such as where the spectacle power to be treated is very high, LASIK with simultaneous corneal crosslinking treatment may help to keep the post LASIK spectacle power stable.
Also as a general rule of thumb, I would advise everyone in general (including those who have not had eye surgery) to refrain from rubbing the eyes hard.
And even though many worry that excessive near work after LASIK, such as with computer use, may cause regression, the good news is that there is no good evidence for this either. So no, you don't have to particularly curtail computer use in an effort to prevent regression, as long as the other things such as age and prior stability of spectacle power apply in your case.
And just a final thought. A little bit of myopic regression in one eye may even be a good thing for those approaching 40 years of age, since this could delay the need to wear reading glasses!

Regression refers to the eye returning back to its original state. Just to clarify, LASIK is a permanent surgery that removes tissue from your cornea thus the eyes technically will not revert to its original state. Although rare, it is still possible for your vision to change after a refractive surgery.+
Here are some ways to lessen the risk of regression after LASIK.
- Ensure your prescription has stabilised proceeding with surgery
- Using prescribed post operative medicated eyedrops diligently
- Studies have shown that patients with higher prescription or astigmatism have a higher risk of regression. You may be on medication longer post-lasers or your doctor may recommend you to go for collagen cross-linking to further strengthen your cornea. It is important to discuss with your ophthalmologist to find out your risk of regression before surgery
It is important to note that the eye is a living thing and that having LASIK does not make it less vulnerable to ageing and wear and tear.
