I made the lens implants for nine years. There are many styles and options, various optic choicest d kens materials. Not sure which models are FAA approved. The multifocal lenses are wonderful thingss, we used to get Thank You letters from patients (amazing, considering we made over 6 million lenses each year!).
BUT . . . most eye doctors do not recommend multifocal lenses to two population groups: pilots and engineers. I'm both . . . Our MF lenses had up to 12 different focal rings, and most people are spectacle free after surgery. There are models that correct for astigmatism, too. Talk to your eye doctor, and bounce it off your AME before doing anything.
LASIK, like RK before it, makes cuts on your cornea, the front of the eye, to compensate for poor focus. Cataracts form in your lens, in the middle of the eye, and in cataract surgery your natural lens is removed and an artificial lens is put in it's place. Takes a few days for everything to settle into permanent place. No stitches, though. It's an amazing process, we all had to watch an actual surgery video (taken through the surgeon's microscope) our first day in the job.
Good luck with whatever you decide to do. If your have any undesired optical effects afterwards, do your best to ignore them. Paying attention and getting aggravated will make them permanent. If you ignore them, your brain will compensate and they will "disappear" from your vision. As remarkable as the technology is, the adaptability of the human brain is even more amazing.
