@kitenski, OK, my prescription is quite low so should be OK. I will raise it though, cheers.

@MorningGory, I think a decent specialist will tell you what your options are just like a good boots specialist

@MorningGory,
Typical complaints for lenses: "I can't see as well as I thought" "they rattle around" "I still need reading glasses". These aren't common but do happen.
For laser: People often get mild dry eye for up to a couple of years. It tends to get better quite quickly but there is some variation in vision with the tear film, which effects vision, for a while then it sorts itself out.
FWIW I got distance laser and will get reading glasses as and when. I'm fortunate in having thick corneas and they can do it again later if needed!
Opthalmologists typically don't get these procedures (unless absolutely needed) as if they do go wrong you typically can't correct them fully with lenses and they need to be able to get "neutral" with their eyes and be able to focus through a slit lamp. So I'm told by my ophthalmologist buddy anyway.

Can be simulated with contact lens

This is reassuring. When I wore contact lenses, relatively briefly, I had different lenses right eye (for distance) and left eye (for closer) and found them fine. Once they were in - it was getting them in and out which I found a hassle because I have little piggy eyes. |
I believe the simulation works best (most realistic) for older folks. For spring chickens like me, I still have some focusing power left. So the difference between the 2 lens got "accommodated" away. That is, my distance eye can still refocus to see medium distance, can even read without reading glasses (at arms length). So my two eyes always work together up to some distance. But that's when I felt the difference and didn't quite like it...
But once one changed to artificial lens, that accommodation will not be there. At least not the same way the natural lens work.

I think the ophthalmologist may have been pulling your leg! Our slit lamps have lovely adjustable eyepieces for focussing! If the laser/lens implant has gone that drastically wrong that you can't see through a slit lamp then you can't see anything else, either.

Just got back from my consultation. My eyes are in good nick although have slight cataract which didn't surprise me as things aren't that sharp even which contacts/glasses.
A perfect candidate for trifocal implants, so booked in for 2 weeks time

You pretty well have to give up driving at night with monovision lenses. I was sure that was the way to go until a friend of a friend had their old lens crumble during a cataract op (this does happen with advanced cataracts a fair bit apparently) which left them blind with no lens and with bits of broken lens floating around in one eye. Imagine that? So I'm having a rethink and holding things further away to see them for the time being.

Not true in my case, I can drive at night no problem after a monovision solution.

How do laser / lens options allow for your eyes changing over time? I didn't need glasses until my mid-40s, but after that my prescription slowly changed every few years; perhaps a littles less after 60 (now 65).
Surgery doesn't seem a good option if your eyes are still going to change afterwards; it's not something you are going to want to repeat every few years!

@ecureuil, lenses are a future proof option, and also mean no cataracts. Laser can need repeating if your eyes change.

@22 dropout, monovision lenses shouldn't affect night vision (think how many cataract ops have been done). My trifocals may have short term night issues until the brain sorts itself out, with a small chance of halos round lights etc which most people are OK with.

Dead right. I meant multi-vision, and to be fair it's what a user tells me as i do not have them myself but, if I was going that way that is what I would have as there must be other corrections available for night light defraction. In their case they just minimised their night driving and found it a small price to pay for the amazing improvement in vision.

Sounds like a case that earlier surgery would actually be a better option than waiting till the cataract got more "advanced"?

You know it makes sense.

@ecureuil, The variables are the thickness/curvature of the crystalline lens within the eye, the axial length of the eye and the curvature of the cornea. The former is removed and replaced with a constant - the artificial lens the strength of which is calculated according to the desired outcome (not necessarily zero prescription as many life long myopes prefer to remain myopic so they have clear near vision without glasses.)
Ageing changes continue with the latter two leading to development of refractive error which is only corrected by glasses. You don't really get a second go at lens implant. It is feasible but the more you bug about the greater the risk of serious complications.
The bigger issue - not everybody is the same and different people have different tolerances, expectations and needs. the outcome that suits one person will not suit another. Some people, post operatively, will complain that their distance/near/night driving is awful with a tiny refractive error whilst others with the same parameters will be delighted with the outcome as they can get away without glasses. Some people will put up with incredibly crap vision as the have had the surgery so they must be fine, even when you demonstrate how much their vision could be improved. Much like senior citizens and driving glasses but that's another subject.
For those clients unhappy with the outcome or if/when they develop a spectacle prescription then they're back to glasses.

How do those changes occur? Something to do with the muscles around the eye or IOP?
|

Nope. The extrinsic ocular muscles only affect the direction of the eyes and the IOP has no real affect on refractive error. The mechanism isn't well understood but, let's face it - we all sag as we age and it only takes a small change in the axial length of the eye or the curvature of the cornea to bring about a significant change in spectacle prescription.
We change shape as we age.

Thanks. I wasn't aware that the axial length might change with age, but as one of those lifelong myopes who still wears glasses after cataract surgery it shouldn't be a problem

Well, had them done yesterday. The procedure was very quick, 5-10 mins per eye.
Things are a bit blurry today but I'm typing this on my Macbook with no glasses (although it's far from perfect!) which is a good sign!

@MorningGory, nice. Mine took a few days to settle down. Surgeon waited 3 months before doing a final eye test for acuity. Now have annual follow-ups.

@pam w, Ta. Getting very good vibes so far - can read the small print on a packet of rice  No halos (from house lights, haven't seen any car headlights yet...). Wrote a document on the PC yesterday - vision was far from perfect but good enough. So I seem to have full range of focus, but the quality needs improving. Given that the eyes are still recovering from the surgery and it can take weeks for the brain to fully work it out, I'll live with that!
Got a follow-up appt on Wed. and can't see him finding anything wrong.

Had a checkup on Wednesday. All looking good and I already had 20/20 vision 5 days after the op 
Improving every day (can improve over a 3 month period) so still very happy.
