The most important thing to remember is-the only person who can ultimately decide whether LASIK is worthwhile, is yourself.
And in the process of making your decision, you should try to understand and imagine what you are in for, in all the various possible scenarios.
To start off, presbyopia/Lao Hua does not entirely or necessarily defeat the purpose of LASIK. But let's consider the various scenarios first.
1. You decide to stick with glasses. In this case, without glasses, you can only see clearly out to about 11cm from your face (for most of your life until eventually you have cataract surgery done in old age). When you get to 40 years old and Lao Hua kicks in, you will need to get progressive glasses (where the top part is for far and the bottom is for near). All the inconvenience of glasses apply, eg fogging, blur vision outside the frames etc.
2. You decide to wear contact lenses. Without the lenses, you can only see right in front of your face, like glasses. When you get to 40 years old, you will either have to wear reading glasses on top of your contact lenses, or purposely undercorrect the lens on one side, so that one eye sees clearly in the distance and the other eye sees clearly for near. Contact lenses can give very good quality vision but can be a hassle to maintain and also can be a problem for people who are into eg watersports.
3. You decide to have refractive surgery (LASIK or ICL if cornea is not thick enough). Most people who do LASIK at 35 will aim to correct both eyes to have good vision in the distance, and for the next ~5 years everything will be clear both far and near. After that, reading glasses will become necessary for near, but far vision will still be clear without glasses.
If you consider the different scenarios, you will see that each has its pros and cons. No matter what option you choose, you will have to make an adjustment once Lao Hua kicks in.
But which scenario would you like? Would you like to be eg 50 and have to wear progressive spectacles all the time, or would you like to be 50 and be spectacle free except when looking at near things?
There is no right or wrong answer, and it's very much each to his or her own, depending on things like individual preferences, hobbies, occupation, and so on.
