It is basically the same approach as using the Televue Dioptrx adapters (but probably cheaper!)
With regard to eye-relief, the Long Perng planetary eyepieces have 20mm eye-relief, as do the Orion "edge-on" and Williams "super planetary" (they are all the same, just different branding: but the Long Perng are a lot cheaper), so if you want to replace your plossls they are a good place to start.
I have moderate astigmatism as well: Venus goes from two "Eiffel towers" inverted on each other (hollow in the middle!), with 18 spikes and covering about 1/2 degree naked eye to a little ball when I wear glasses; and all of a sudden there are twice as many stars in the sky as well! However, I find that when the exit pupil is around 2mm or less I really don't need the glasses.
I echo the comment about taking care when you first get the glasses. I didn't run off the road, but I had to be vary careful when using stars as my feet weren't in the same spot as they used to be! It was fine after a few days though.
All the best,
Dean
