Yes, a clear center is very good.
People have asked my where all the burn marks from the 3,000 zaps are and whether those black marks were hemmhorrages.
These pics are of the macular region. There are large areas not shown. I managed to sneak into my opto's office to get these, and it took a few minutes to figure out how to export and burn them. I didn't get copies of the peripheral images as he had a patient waiting and my time was gone.
Compare to this image.

This pic shows large areas of lasered tissue. You can see the untouched macula in the center. Mine are similar.
The blackened areas are scarring. All doc said was they can turn that color over time.
I think the most difficult part is the realization that these burned areas are dead and the vision is gone. It will never come back. It's sacrificed for that little plot of rich land in the middle.
