[Development of atraumatic microneedles for use in ophthalmology].
Measurement of the force interaction of the microneedle with the pierced material helps quantitatively estimate the microneedle functional characteristics and cut down the time for control. Flat microneedles with a trihedral point require the least pricking effort; the use of such needles is most desirable in suturing solid biological tissues (cornea, sclera, etc.). Experimental samples of Soviet ophthalmologic microneedles are not inferior to foreign ones. Employment of a mathematical model helps select the optimal combinations of the values of the geometrical parameters that will provide the least pricking effort.
