Here's what I got over several exams:

stereo
O.D. Sph +1.75 Cyl +0.25 Axis 17 Prism 2^1 Base BO
O.S. Sph +0.50 Cyl +0.50 Axis 110  "    "    "   "
============
1999 perscription
SPHERE-CYLINDER-AXIS  eye size 55/16
DIST R -1.00 +.25 15
DIST L -1.25 +.25 125

Of course, I don't know enough about the terminology to
know what it's telling me! I presume the Prism figure
