Last night, the Apple Store pushed back the despatch date of the Mac Pro by another 6 days, to 13th Feb, meaning that I almost certainlyu wouldn't see it till w/c 18th. Enough is enough.

I asked a mate of mine if his distributors had any in stock, They do. So one is ordered for a Saturday delivery, and Apple have been cancelled. Lets just hope they process the refund promptly ...

In other news, I am considering (just considering) laser surgery on my eyes. I have obtained a copy of my last prescription, from May 06, and that indicates it's possible, even with my myopia and astigmatism, so I've booked an eye test for Monday to see what the current deterioration is. I expect when push comes to shove, I'll be too squeamish to do it, and too mean to pay out £2k, but it's nice to have the facts before I dismiss the idea.

Not that I want to put you off, as I've friends who had great success with the surgery but ...

... have they reduced the incidence of night vision damage? At one time I seem to recall that 1 in 3 people ended up with night vision sufficiently diminished that it should have stopped them driving at night (halos and glare primarily)

Yes, I've heard this from other people. It's something I shall be asking about. My night vision is not great now, mind you - Pete generally does the night driving.

It looks like it's because of the scar tissue where they do the cutting and lasing ... there's at least one other form of eye surgery I'm keeping an eye on (where they insert a lens into the cornea or thereabouts, or put in a ring of some kind) but that really requires you to have a small to average pupil size and I don't know if I do ... a friend was about to get it a year ago so I did a chunk of reading up on it.

I suppose if you already have poor night vision and don't drive at night, then you don't have much to worry about.

Best of luck and let me know how it works out!

As I understand it, it depends on the amount of correction they need to do and the internal eye pressure. They are therefore limited by the thickness of corneal wall they can take off, and for heavier prescriptions, you then end up with a smaller burn diameter. This means that, when your eyes dilate, you get a clear image from the middle bit, and not on the un-affected areas: Hence the starry image.

Go for the assessment, and they'll advise what's likely. In fact, go for several with different companies, and see if they agree... Once they've measured your corneal wall thickness vs internal eye pressure (blow a puff of air on the air surface and measure deflection) they can see how much they can take off, and whether it's viable.

In my case, I have next to no effect at all. My eyes don't dilate that much, and my corneal walls were on the thick side in the first place...
