Surgery
When stents are developed, various organic materials are tested on living organisms to establish the technical suitability and tolerability of the materials. Since bioresorbable polymers are extremely heat sensitive, femtosecond lasers are the only tool that can be used to manufacture these finely textured implants without damaging them.

Metrology
A new method of laser metrology for analyzing blood values is currently undergoing tests. Blood is passed through a micropipette that is subjected to lateral illumination by laser radiation. Introducing measurement windows into the surface of the glass pipette presents a considerable challenge, because it is important not to impair the optical quality of the pipette surface.
Because the materials of the pipette and the coating have different machining thresholds, the femtosecond laser is able to uncover small measurement windows without damaging the material of the pipette.

Optometrics
Lasering micropores into contact lenses increases their comfort and convenience in wear. The pores enable fluids to be exchanged between the cornea and the surface of the lens, thus preventing the surface from drying out and enabling the eyelid to slide over the eye more easily and without discomfort. The openings also allow oxygen to reach the cornea.
