[The effect of UV radiation on Trevira threads].
The UV sensitivity of trevira threads, which are used as material of loops in intraocular lenses, was examined under different conditions. Severe changes of the thread surface were induced by direct UV radiation without absorbing media. The in vitro alterations of the surface were smaller. The in vivo changes were unimportant and not clearly distinguishable from biological changes. Nevertheless, it is advisable for people using intraocular lenses to provide with short-wavelength filtration devices, such as absorptive spectacles.
