Had LASIK done 8 years ago, best money I've ever spent...came out with 20/10 vision and still have it to this day, only minor halos at night and very occassional dry eyes, rarely needing eye drops...having the exams done by techs isn't such an issue, if they notice anything questionable an optometrist comes in and the convenience of having it so close would be worth it if you did have problems...if you were in pain and needed to be checked out would you want to drive the 4 hours, or rather would you be able to find someone to drive you the 4 hours? Yes there has been some problems over the years but it's a mature procedure now with fewer complications than ever...I mean people can still die having their appendix removed so everything has it's risks, the payoff for it is soo worth it though.
