[Laser treatment of the eyes of microsurgical needles].

Experimental results of studies on ability to treat by laser beam holes into needles by 0.15-1.0 mm diameter made of steel are presented.

[Optimal coefficient of overlap of light spots during laser hardening of medical instruments].

The optimum coefficient of light spot intercepts in the course of laser hardening medical instruments is determined for the case when there are no unirradiated sites on the surface under treatment. The increase in the light spot diameter during irradiation has been shown to be followed by more rapid expansion of the hardened area in comparison with the one of the tempered zone.
