An elective procedure which very likely adds lifelong negative side-effects?
Doctors do no harm unless absolutely necessary. Lasik surgeons know of these life-altering negative symptoms and still happily take your money to give you your dream realized. As their industry exists right now, they serve consumers, not sick patients. Lasik surgeons must not consider themselves a doctor, so don't trust them like they are one.
It doesn't matter which eye surgery is used, ocular surgery destroys nerves in the surface of the eye which are essential for communicating to the rest of the body the needs of the eye, like adjustments to tear composition to ensure tear quality necessary for maintaining ocular health.
Negative side-effects may be just an inconvenience for a few decades, but they can easily turn into terrible complications should your body's general health degrade such that slightly inconvenient eye symptoms becomes chronic eye pain.
For dry eye pain, there is no known cure. Dry eye pain can only be mitigated, but never cured. Dry eye pain causes tension in the muscles in the head and neck which can be triggered to form severe headaches. The muscle tension caused by dry eye pain can trigger psychological changes such as anxiety, chronic bouts of drowsiness, decreased stress tolerance, and heart palpitations. Chronic pain, such as from dry eyes, can cause chronic physical exhaustion.
The Lasik/elective eye surgery industry is terribly wealthy, and its side-effects is not well understood and suspicious. More research is necessary to determine exactly the scope and severity of its long-term side effects -- there really is very little data here and that should be terribly concerning for a procedure which is sold as incredibly safe.
Be skeptical of it and support predicating its growth on further research of the scale, scope, and severity of its side-effects.
If you're considering having a Lasik-like procedure performed on your eyes, first join a Lasik complications group/forum on the internet. In addition seek third-party research which attempts to assess the true scale of complications and how to cure those complications should they arise in you. It's far more than 1-2% which have complications, think closer to 10-30%.
I'm guessing a JS-controlled framework, like React or Mithril, would be a better fit if you choose to use PureScript as a core piece of your app, as they are function-based, like PureScript.
