I'm researching on the topic.
Bad night vision (halo, startbusting and ghosting) is
very common.
Much more common if you have larger pupils than usual, as I seem to have.
Dry eye is also quite common, another thing that worries me as I get red eyes after contact lenses (but no other dry eyes symptoms without).
I really wanna do it as i have -4.75 so my lenses are quite thick but at the same time I'm scared about dry eyes and
very bad night vision (seems weird but I would gladly accept a bit of haloing if I'd be assured that was all).
I've also been to the doctor whom talked me out of ICL (implantable contacts) and says I'm a perfect candidate for LASIK but what irks me is that it feels like I'm getting a sales pitch rather than the unadulterated truth, which would would make you feel safer (good salesmen should understand when to stop selling!).
Here's our mail convo after the check up (stupid me I didn't have too many LASIK questions as I went in with the idea of doing ICL):
Quote:
1. 20/20 chances
What are the chances for a subject like me to get a result of 20/20 6 months after the operation?
And what are the chances of a vision as good as eyeglasses and contacts?
99%, 99%
2. Unresolved issues
What percentage of your patients report unresolved complications six months after surgery and what are my chances of not developing any (includes objective and subjective complications such as halos, starbursts, dry eyes) ?
01%, 0.1%
3. Large pupils and dim light
As I have large pupils, what are my chances of not getting any halos or difficulties in dim light conditions?
0.1%
3. Laser or microkeratome
Will you use a laser to create the flap or a mechanical microkeratome?
Femtolaser!!! It is every so much more safe!
4. Machine and experience
What kind of machine are you using, and what's your experience with that particular one?
Wavelight Allegretto. 10 Years. Excellent.
5. Wearing contacts before check up
I was actually wearing soft contact lenses this Saturday 29.03.2014, 4 days before the check up. Is it an issue?
We need to see you 2 weeks out of Contacts before your SPAM.
I forwarded this mail to the lovely person who started the website "LASIK complication", here's his/her reply:

Sales pitch.
1. Chances of 20/20 visual acuity initially are very high, probably over 95% (results tend to decline over time). Chances of visual quality as good as with glasses, probably less than 50%. Visual acuity and visual quality are not the same. See:
http://lasikcomplications.com/mythof2020.htm
2. Clearly he does not count chronic dry eyes and night vision problems. Clinical trials show that roughly 20% of patients report dry eyes and night vision problems at the 6-month end point of the study. Consumer Reports conducted an independent survey of laser eye surgery patients and found similar numbers -- 22% of patients reporting problems six months after surgery. See:
http://www.lasikcomplications.com/consumerreports.htm
3. If your pupils are larger than the laser optical zone, not including the blend zone, then your chances for night vision problems is 99%. Remember, LASIK surgeons don't consider debilitating night vision problems as complications -- they dismiss it as an "expected temporary side effect". So naturally he's going to say that there's no chance of a problem. Apparently many patients with minor night vision problems get used to it over time, so maybe that's why they call it "temporary". Patients with severe night vision problems are unable to adapt.

3. (You have two 3's). There are pluses and minuses to femtosecond. I have a page on that.

4. 10 years experience on the laser he uses? Then how can it be the "latest technology"? (I'm being sarcastic -- they talk out of both sides of their mouths). Here's the Wavelight Allegretto Patient Information Booklet.

5. Soft lenses are not a big factor, and 2 weeks sounds about right for being out of them before the pre-op exam. (Different story for hard lenses).
6. Since you didn't ask, read Top Ten Reasons Not To Have LASIK:
http://lasikcomplications.com/TopTenReasons.htm
There is no sound medical reason to risk your eyesight. If you have problems (and I believe you will have problems with dry eyes and night vision), you will have to live with profound regret for not following your instincts.
I am not a doctor.
