How safe is lasik surgery these days?!

Complications vary quite substantially, because they're dependent on the individual surgeon, the model of laser being used, and the post-operative care (what type of antibiotics, frequency of steroid dosing, etc.) Generally speaking, things are less risky than they were five years ago, because everyone in the field is constantly striving for improvement. Off the top of my head, I'd say the big risks are visual disturbances (haloes, glare, etc), infection, and loss of best-corrected visual acuity. The first one is fairly common, probably around 10%, but in many cases improves 6-12 months after surgery. The second should be next to nothing at any surgical centre, provided you follow their directions for drops afterwards. (When I went for my procedure, I was quoted a rate of less than 1/100,000, because they'd done 100,000 procedures and hadn't had one yet.) Loss of BCVA is more troubling, I'd estimate it's probably under 1%, and is certainly better with wavefront technology and aberration measurements, which are more or less standard nowadays. A lot of people complain about needing glasses or contacts afterwards; I think it's important to remember that wherever you go, they can't stop your eyes from changing or aging, and realize that the goal of laser surgery generally is to improve your vision and decrease your dependence on glasses.
The safest procedure to correct astigmatism (with or without myopia or hyperopia) is custom / wavefront-guided refractive surgery. I'm not convinced that LASIK (with bladeless technology, aka IntraLase) or PRK is better; visual outcomes tend to be the same. LASIK is much more comfortable during healing than PRK, so it's generally the preferred procedure. I'd never recommend the microkeratome-based (non-bladeless) procedure to anyone; many of the flap-related complications are much more common with this older method.
TLC has a good reputation, but so do many other centres, including smaller regional ones. Surgical outcome is really more dependent on the surgeon than the centre, whereas price and warranty and so on are centre-dependent.

I'm an optometrist. I had LASIK done by a Toronto-based surgeon at a Toronto-based centre a couple months ago. Generally, regardless of where people go, they are pleased with the results and service, and we see very few complications, regardless of surgeon, centre, or procedure.

hmmm. i've been waiting for somebody to answer b/c i want lasik surgery too... guess, you're just gonna have to luck it out and hope for the best =/
