Cylindrical Zernike Surface

Is there a way to simulate the Zernike polynomials on a cylindrical lens? I have a cylindrical lens that is quite long, and with some Zernike terms, it gives a weird shape.
This is the basic cylindrical array:

But with a Zernike term, it becomes:

It seems that the Zernike is applied in X and Y, but I only want it in one of these directions.

Some more digging into the problem, might the normalization radius be of importance here? How does that one work exactly?

As I put the normalization radius bigger, the array seems to get a ‘normal’ layout again.
