Wow! Seems like Lasik is so much cheaper nowadays! I had mine done back in 2001 at SNEC, but Dr Lim-Li, paid $2.5k each eye. Was playing a lot of sports then, and I was always paranoid abt what'd happen if I'd sustained an eye injury and would have to go to the hospital, and they have a hard time removing. Anyway, it did happen to me and cos my eye closed up due to the swelling, and it was a nightmare forcing it open to get to the contact.
Anyway, my myopia was abt 700* with 300* astig, a nightmare case, properly just borderline to qualify. My eyes were rather dry too. The first one done by Dr Lim was smooth, barring the usual post op scratchiness and tearing, but almost immediately, I could see rather clearly oredi. But the next morning, I was ok. The second op wasn't so good, done by another doctor whose name I shan't mention cos it's not fair to him (might be an anamoly). It was painful, plus they left an eyelash in under the flap!
It's been quite a number of years now since I had it done, and unfortunately, my astig has returned and my myopia is now up to 100*. Frankly, I dunno whether it was because they under corrected it, but I do need to wear glasses in darker areas and driving at night. Do I regret it? Depends. If you're talking abt going from 700* down to 100*, then I'm grateful that I'm not totally dependent on my glasses. My disappointment stems from my unmoderated sense of optimism, meaning that I'd expected too much from it. But overall, I'm still glad I went for it, although it wasn't perfect.
Hope this helps!
