Depending on the sequence and the field strength there can be artifacts that look like eye movement and are difficult to separate. To avoid eye movement should the patient not only close the eyes or fix a point, but also with closed eyes think about not to move the eyes.
Other artifacts (e.g. ghosting) can be reduced with fat suppression, reduction of the water fat shift, T1 with a long TE (to reduce the brightness of fat), and/or a higher matrix.
Also the perfect positioning of the coil and a homogeneity correction will improve the image quality. I do not know a post processing program that removes those artifacts.
