Dialyzer and process of modification of a dialyzer with a laser are disclosed. Process for producing a dialyzer includes a medium IR pulsed laser surface treatment at least in place of the last precision cut. Process reduces standstill times during treatment of dialyzer ends to achieve a smooth surface of the dialyzer ends. Dialyzer hollow membrane ends in entrance and exit regions in the region of plastic embedding are funnel shaped, have rounded edges, and, along with the plastic, form a smooth, melted, and purified surface.
