“What are the disadvantages of laser eye surgery?”

First, it's important to make sure you're a good candidate for LASIK If you are then being close to 40 there are things you need to consider If you make both eyes perfect for distance vision then in the near future, you will need glasses for reading. This is because it is an eye muscle problem and lens problem that LASIK doesn't fix What some people do is get one eye great for distance and the other eye made for near activities. You can try this with contacts.

For you, your eyes are going to be presbyopic soon. If you're fully corrected for myopia, you will become presbyopic and unable to read without glasses after laser treatment. Think first. Unless you can adapt to reading glasses or try monovision.
