The two 'short' versions are designed to fit into smaller frames. This
involves a slight compromise in the usability of the multifocal lens.

The different indexes (indices?) (e.g 1.6 1.71 1.74) refer to how thin
the lens will be for a given frame (higher index = thinner).

Assuming the 'Panorama' is what we in Australia call the 'Panamic' I
have found it to be very good.

BUT... what's much more important than the lens type is the care taken
in the fitting measurements, the manufacturing, the checking/quality
control, the frame adjustment, and the after-sales service. If these
aren't all spot-on, then you could have the best multifocal in the world
and still be unhappy.

So I'd make your decision based on which outlet gave you the best
impression as being honest, thorough, knowledgable, caring, and
listening to your needs, rather than the quote for the lens.

This is a difficult Rx for progressive lenses. I would take a serious look
at Rodenstock Impression ILT 1.74.

I could name about a hundred more, along with at least ten more materials.

Peter,

This is a challenging Rx to get right the first time, especially in a
progressive addition lens. Watch out for lens materials that have low "Abbe"
numbers. With your Rx you might find the off-axis vision unacceptable. The worst
performers have an index of refraction of 1.59 (polycarbonate), 1.66, and 1.74.

Don't be too concerned about the lens brand and manufacturer. Lot's of marketing
hype.

Lenses that are properly positioned, even the cheapest and most low tech
designs, will out perform the most expensive designs  that are poorly fit.

The frame must allow the lenses to be and placed properly in front of your eyes.
Think function before fashion. You can usually have both, but a good optician
should be selecting the frame for you.

You should continue to learn all that you can about ophthalmic lenses so that
you can screen for knowledgable and thorough opticians. Ask tour doctor and
friends for a recommendation. Once you get a short list make an appointment  to
have your glasses adjusted for proper fit and vision. Ask questions, watch, and
listen.

Hope this helps
