Not much of Liebesträume No. 3 is easy per se, but these specific jumps starting just after the modulation to E major are really stymying me. In these spots, the right hand jumps up by more than a full octave, and the left hand jumps down by more than a full octave. You only have an eighth note's worth of timing to get into position. I can consistently land either jump if I'm looking at it, but if I'm not looking at it sometimes I'm off by a whole step (which sounds awful), and due to the tight timing and the wide span, it's infeasible to look at both hands at once.
Here is the score in question, with red highlights over the places that I find most difficult, and yellow highlights over "honorable mentions" that have an extra eighth note or so of preceding rest in the right hand, allowing me to quickly look right before looking left:

Or, for a video performance, here's Khatia Buniatishvili:
I've tried to "just get good" at the jumps, and I've gotten better, but I've been practicing this piece off and on for a year and I'm still not near a consistency that I'm satisfied with. What kind of techniques can I use to land these jumps more precisely?
