I have a very particular way of reading it where I try to space out the sounds of the letters that are on either side of the omega, so that that central absence is there, and it's formed by sounds rather than a visual shape on the page.
See if you have the poem by memory. Turn the light off while going to sleep and try to recite the poem. If you come to a part you don't have memorized, maybe that's the part you need to work on. Not reliably, but sometimes.
For me, the unique quality of poetry is that it is vocal. It's on a human scale. It comes out of one person's body one syllable at a time. There doesn't have to be anybody else around
I don't know if I revise towards a sound but I certainly read it out loud. It's certainly not just a visual thing. It may be conceptual, but it's not conceptual without reference to the other sensory modalities. So for sure it has to read right—in my mouth.
