[Overview of the clinical use of the specular reflex in intraocular lenses].

On both surfaces of the intraocular lens, due to its physical properties, an intense and homogenous reflex develops suitable for retrograde illumination of the cornea, anterior chamber, the remainder of the lenticular capsule, for examination of amorphous, cellular and fibrinous membranes on the surface of the intraocular lens and visualization of defects of the intraocular lens. Based on experience from specular routine microscopic examinations the author considers that visualization of defects of the Descemet's membrane is most useful as well as of precipitates on the endothelium in opaque structures of the cornea, evaluation of the immunological reaction on the surface of the intraocular lens as a picture of the dynamics of the reaction and biocompatibility of the material of the intraocular lens, detection of defects which occur during manufacture and manipulation in the operation theatre in vivo and defects during YAG-laser therapy with possible subsequent adjustment of the intensity and focusing.
