Leather Covered Desk - imprints/dent

I have a desk covered in leather that now has an imprint from keeping a computer on it for too long (see attached photos). It is black leather with a Crypton finish. I would now like to use the desk without a computer on it but it looks very unsightly. Is there anything that I can do to make the leather imprints disappear?
