That's a very tough correction(prescription) to get good results with
lasik.
Not so much with the hyperopia but with the added moderate astigmatism
the results could be shakey. If you're still doing well with your cl's
I'd stay with what you have.

Since he has a decent chunk of cyl, how about using wavefront LASIK to
zap the astigmatism, leaving him in straight sphere contact lenses?  

Might give more stable vision with the contacts, no?

. . . or . . . to follow up on my own post . . . zap the cyl AND a
diopter or two of sphere . . . then put him in straight sphere CL's.

Just a thought....

The FDA studies on the original Autonomous Laser with LADAR tracking were
brand new about five years ago.  The maximum achievable successfully on that
instrument was +6.00 sph with -6.00 astig.  My own Rx was +2.50 -3.00 back
then and I had to wait for this new technology to be approved before I had
my own eyes LASIK'd.  Corneal shape and thickness will play a role in
obtaining the maximum Rx.  Also, the Intralase laser can create the thinnest
possible flap to coax more prescription out of the cornea.  Find the most
experienced doctor you can find.
