Hydrogen Peroxide solutions kill the most disease-causing microorganisms and have no preservatives, because after the 6 hour storage it becomes just water. Multipurpose disinfecting solutions (MPDS) while killing most pathological microorganism have preservatives that often irritate the eye.
I do recommend daily disposable contact lenses although they are not available for all prescriptions (high astigmats/toric wearers, and bifocal contact lenses). The manufacturers are working on more options, though! You can insert with sterile saline.
LASIK is good if you have good results, which is not anybody. Some are better candidates then others.
LASIK will not correct for your reading glasses (and later computer glasses), because that linearly declines with age.
I know a young healthy 26 year old patient with no medical history have 20/60 best corrected vision with glasses after LASIK in the USA which means they are no longer legal to drive even with glasses.
If you do LASIK, do Custom LASIK (costs more, but better results) and find a good surgeon. Don't go cheap for a procedure that could have bad effects!
Dry eyes and glare tend to get worse with age (esp. after age 40) in both sexes, regardless of LASIK (but it tends to make it worse).
Some LASIK patients that were fine when young find as they approach their 40's and 50's they have difficulty with night driving because of glares and optical aberrations. Anytime you cut the eye in refractive surgery you get some optical changes.
Also one of the things we learned the hard way after the wars in Iraq and Afghanistan is that LASIK eyes are more like to explode or have damage when trauma hits the eye.
Even airbags and car accidents are more likely to cause retinal detachments in LASIK eyes.
Retinal detachments if not fixed in time (usually 24-72 hours) can often cause permanent vision loss.
