What are you looking at when your opponent strikes the ball?
While it might seem to go without saying that one should look at the opponent's racket striking the ball I've found better results, when I am at the baseline, to look through the net at the service line and peripherally see the ball struck.
The reason is that I then don't need to think about refocusing my eyes on the ball when it hits the ground - I need only focus once.
I find when I do this I can see the seams of the ball far more often.
As a result there's less mental confusion if it's blurry ("panic") and more likelihood to see the snapshot of your racket plowing through the ball.
