We study the long-time behaviour of the solutions to a nonlinear damped anisotropic sixth-order Schrödinger type equation in $ \mathbb{R}^2 $ that reads
$ u_t+i\Delta u-i \left(\partial_y^4 u-\partial_y^6 u\right)+ig(|u|^2)u+\gamma u = f\,,\;\;(t,(x,y))\in \mathbb{R}\times \mathbb{R}^2\,. $
We prove that this behaviour is described by the existence of regular global attractor in an anisotropic Sobolev space with finite fractal dimension.
