In the Effect Controls panel:

Matte scales the distortion per pixel, read where the pixel lands: white bends at the full Field of view, grey less, black not at all. Invert reads that matte inverted.

Field of view changes how wide the lens is.
Reverse, when off, adds the bow. On, it removes the bow instead, giving a pincushion effect.
Orientation picks which side of the frame the angle spans.
Centre X and Centre Y place the optical centre to bend around.
Edges adjusts what to fill resulting transparent pixels with. Transparent is the default. Repeat smears the border pixel outward. Mirror folds the picture back on itself.
Mix: how much of the result replaces the original.
Matte and Invert drive the strength of the effect from another layer’s brightness; see Effects.
