    I am considering LASIK sometime in the not-to-distant future. I have been wearing glasses since the 4th grade, I am 56 now, and I am sick of dealing with them. When I am at the EP they become even more of a hassle. on, off, on, off ad nauseum and it really takes away from the pleasure of the hobby.

    Same here... I tried contact lenses but found that the aberrations they induced at the scope were unsatisfactory. I would be devastated if I got LASIK and got stuck with the same aberrations, but without any recourse to correct it.

    Luckily I don't have much astigmatism (.25 diopter) so I don't need to wear my glasses at the eyepiece. But the on-off-on-off is really irritating.

    There is another non invasive procedure available to some where they will reshape the eye slowly over a period of one to two years using hard conacts. Once the procedure is done one only has to wear a retainer (hard contact) at night one or two nights a week to maintain fully corrected or close to fully corrected vision. Some eye doctors specialize in this method and I would recommend to shop around fully if one had interest. My brother went this path a bit over 10 years ago with great success. Not for everyone, but this is an option and non invasive.

    Had it done about 5 years ago. Did have the halo for a few months, but it finally went away. My problem now is floaters,,,lots and lots of floaters. Also, I don't see as well in dim/darkness as I used too...

    Interesting thread - I wondered about it some years back, but at the time it looked as though it was basically aimed at correcting daytime vision - I.e. the central part of the lens, rather than the larger area you'd need for night vision, so the potential adverse effects at night put me off... The wife of a friend of mine had eye surgery a while back - lens replacement, rather than LASIK - which didn't go too well - apparently, the lens didn't stay where it was supposed to. and it's going to be several months before the eye heals enough for them to try and correct it. For me, I'd rather stay with glasses - which fix things nicely - instead of risking unfixable side effects -- especially since I'm mainly short sighted, so I can just refocus without the glasses without astigmatism being a significant problem.

    I've had LASIK, and did a whole lot of research before having it done. I can share some of that, plus my own experience:

    First, you have to be realistic about the risks with respect to astronomy. The most common reported side-effect of LASIK is reduced night vision. This is usually reported with respect to driving, so it may be not so much a reduction in sensitivity, but a higher sensitivity to glare and/or more difficulty with dark adaptation. My own experience is that i definitely found night driving to be a bit more challenging, and make sure my vehicles now have HID headlights. However, if I go out to a dark zone and let my eyes adapt I can see the things you're supposed to see at that level of darkness - milky way, faint DSO's, etc. So maybe it's just a glare or adaptation thing. It's possible though that your absolute sensitivity to light will be reduced somewhat.

    Another risk from LASIK is that you will wind up with some scarring that will manifest itself as halos around point sources of light or diffraction patterns. For most people this goes away completely after a few months to a couple of years, but I still have it from time to time. If I look at a star field through an eyepiece I do see some diffraction-type aberrations around the brightest stars. The amount of this varies from day to day. However, I'm not sure I'd trade that for glasses, because when I had thick glasses it was very difficult to look through most eyepieces at all, and if my glasses weren't perfectly clean I'd get halos and aberration anyway.

    Another very common side effect is dry eyes. I still have this problem today, and I had LASIK more than 5 years ago. I carry little eyedrop ampules with me in my pocket. Usually it's only first thing in the morning that I need eyedrops, but sometimes if I'm doing something that causes me to forget to blink for a while (like staring in an eyepiece) I can feel the dryness and I'll put a drop or two in. Not everyone has this issue. But if you're considering LASIK, be very honest with yourself if you already have dry eyes.

    Another potential issue with LASIK is vision instability. My vision is often 20/15 uncorrected - way better than I had with my glasses. But there are days when it feels like they are 20/30, and distant objects are slightly out of focus. I had to get a new vision test for a motorcycle license last year, and almost failed it. Then a couple of days later I felt like I had laser-beam acuity.

    Yet another risk is an increase in 'floaters'. This isn't due to the LASIK burning, but the result of the suction device they put on your eye to hold it in place. This can dislodge material stuck to the inside of the eyeball and cause it to float around in your ocular fluid. That's what floaters are. You can get the same thing from getting hit in the eye or in the head, or even rubbing your eye vigorously. I think it's more common in older people. I have quite a few floaters, but I'm not sure how much is due to LASIK and how much is due to other activities I do that are hard on the eyes.

    A lot of the risks of LASIK are the result of pre-existing eye conditions. If you have dry eyes, you may have a problem. If you have abnormally large pupils you are more likely to get halos. If you're considering it, get an evaluation from someone who doesn't have an incentive to shade the truth (i.e. not from the people trying to sell you the procedure).

    Be aware that there are different kinds of LASIK machines out there. The very cheapest places may be using old hardware that has already been amortized. The biggest cost for LASIK companies is the cost of the very expensive computerized machines that do this procedure, and my understanding is that the cheaper companies will sometimes buy the older machines from the more upscale places as they themselves upgrade to the latest stuff. The best machines will have automatic eye tracking and do everything by laser with no physical knives involved. They generally work to a higher precision and have fewer complications.

    The procedure itself is no big deal. It's completely painless and only takes a few minutes. Don't be scared of that at all. Basically they freeze your eye with some drops, then they put a suction device on your eye to hold it in place. The pressure will cause your eye to 'black out' so you can't see anything. That's the most uncomfortable part of the whole procedure. Then you just hold still and you'll hear a few 'zip' sounds from the laser - and that's it. The worst part of the whole thing for me was having to wear eye shields to bed for a few days.

    The bottom line for me is that LASIK hasn't been a panacea, but I'm glad I had it done. Even with the limitations and small side effects I have, it beats the hell out of being nearly blind without glasses on. I can play sports I never used to be able to play, I don't have to pay for new glasses every year, and my overall vision is better. If I were a professional astronomer, I might have come to a different conclusion. Only you can decide if the risks are worth the benefits, but for me it's worked out okay.

    My grandmother had LASIK, and she hasn't complained about looking through my scope. At first she had a lot of problems though. It takes a long time for your eyes to get back to normal after the surgery.

    I had Lasik in 2002. There are halos around car headlights, but not too annoying. I never had any issues looking at stars though since they are so much fainter than headlights.

    I have known over a dozen people over the last 10 years to get LASIK on their eyes. Only one person's wrong.... my aunt had to go in 3 times over a year and a half to get her vision how they intended in the first place. She is still significantly more photo sensitive as a permanent side effect.

    I would not recommend any pure elective surgery on the eyes, as I have family in the medical profession and know of some nasty outcomes. Cataract surgery if you need it, is a must. But like boardtrackbob says, there are side effects that take getting used to.

    For any surgery my rule is to follow at least two doctors (preferably specialists) advice. Do not lead them into your opinion, and if you can help it do not let them know they are the second opinion you are seeking. Try to give a level playing field to see what their own opinion is.

    Always get at least a second opinion when it is something that cannot be easily fixed (if ever) when it goes bad.

    All good advice. In two weeks I am going for my first consulation to find out if I am suitable for Lasik surgery. If I go ahead it will be for the Wavefront 3D process which is expensive. There is a lot of info on the net about the pros and cons of Lasik surgery but not too much around for telescope users like us.
