well yes, there's "hope". but you're right...you're not a great candidate. the lasik & prk (and lasek, yadda yadda) procedures for that type of Rx are less predictable. not more DANGEROUS...not likely to blind you or anything. just less likely to be 20/20 after the surgery.
are there any new types of machine that might be coming out that could help
the ones that would help are already out. VISX wavescan, etc.
if you're really interested, go back to the surgeon or to a different surgeon.
