Trying to shorten an eyeball is like shortening a finger. Wont happen.
I know an enlongated eye can sometimes led to a burst/detached retina.
That can often be fixed and in the future there will be labatory grown
retinas to replace damaged ones. There is also talk of making retinas
with higher density rods/cones for vision in the 20/5 to 20/2(!) range!

I have news for you, presbyopes once they get to age 55+ have no
accomodation and report that things are blurry out to 6+ feet or 2
meters! Anyone can easily simulate this by overcorrecting themselves
with glasses. I was shocked how blurry everything was at 3, 5, even 8
feet away but way, way out in the distance, like looking at the trees
20+ feet away they were so clear I could see every leaf and branch! An
overcorrection does NOT improve BCVA, its the same as the proper
correction that makes me plano, it just blurs things that arent far
away. With even *more* overcorrection, even distance vision gets
blurry. Presbyopes that end overcorrected at *all* will need bifocals
or better yet progressive glasses. If they end exactly plano, they will
see fine from 2 meters, 6-7+ feet away.
I can show you a couple stories on the net of presbyopes with low
myopia who regretted it. I also know in person several low myopic
presbyopes who consider their myopia a blessing and they smile when
they brag how they can read and see from near without those danged
readers!

Its the opposite from what ive seen. A presbyope that is -2 sees as
well as someone who is plano wearing +2 readers. Readers isnt the real
problem, not seeing clearly at 2 meters or less is. Youd need
progressives all the time for anything 2 meters and closer. Lasik can
help if they spend most of their time playing sports, fishing, hunting.
But many people spend time on the computer, reading or stuff like
knitting. Presbyopic people with low myopia have the least to gain.

I disagree, myopia compenstates for presbyopia in the same way readers
do. Next time you see an old myope, let him/her demostrate his/her
ability to read without any glasses! Any myopia of -1.5 or more will
counteract presbyopia enough to eliminate dependancy on readers. Myope
of -.5 to -1 will reduce dependancy on readers. You are forgetting the
fact mild myopia does NOT blur distance vision much. You, for example
can do most things without minus glasses, yet you dont need readers and
wont for a long time if you keep your myopia(which you wont if you get
enhanced) I think slightly blurred distance vision is a "fair" price
and "worth" it in order to keep out of readers, but thats my opinion.
You can always wear minus glasses for driving or watching movies but
its nice not to need readers for everything or carry them like a
necklace, see pictures below. I see old people everywhere that wear
their readers like a necklace!

ill take the thick full figured ones with wonderful ample curves which
for some reason, not everyone finds attractive. You can keep the skinny
ones, dont want em.

Nah, my accomodation is improving or rather, I am accepting less minus.
I have tonic accomodation, pseudomyopia, accomodative spasms, etc. This
means I may be a -3 in axial myopia under cycloplegia but a -5 if you
include pseudomyopia under manifest. some of my accomodation is "tied
up" or "stuck"

They wont go back if I learn to relax my accomodation. Whatever myopia
I have under a 4 day regime of atropine is my real myopia. Because I
can see quite well from near with my -3.25 glasses, I may only be
around a -3 in real myopia. Right now I do need -5 to see perfect in
distance but they "overcorrect" me for near.

not the entire eye, just the ciliary muscles. You know when you look at
something up close, it becomes clear in a split second then if you look
away quickly, its blurry for a split second? Ive looked at near so much
my muscles have become overworked and too tense so they dont relax
fully and I am stuck in accomodation. Optometrists have been telling me
this for a while now and that I have little or no presbyopia, but tonic
accomodation's symptoms include "presbyopia" that will go away once I
relax it. I know what presbyopia is because of this and realize how
useful myopia is in counteracting presbyopia.

Then they are lying. Even if they are happy in spite of their
complications, they still wished their lasik went perfect then they
would be ten times happier.
