I've been tested at vista but haven't had it done due to the cost. I find it funny how they have radio ads comparing the costs of laser surgery to 10 years of contacts/glasses/optometrist visits etc. - If I could pay off the surgery over 10 years I'd have done it already.
I like how vista have the wavefront analysis, which gives a must more tailored result.
One thing I found out while I was there was that the flap that create using lasik never actually heals o.0
Based on that I'd want ASLA even if my eyes weren't more suited for it.
