[The use of viscoelastic compounds in cataract surgery].
The viscoelastic substances are very useful generally in cataract surgery, but absolutely useful in phacoemulsification. In present is used for viscoelastic compounds two terms that assemble the rheologic and physics-chemical properties: is said about the viscoelastic substance that is cohesive and dispersive (respective cohesivity or dispersivity property). Thus both types of viscoelastic substances--cohesive and dispersive--is used, sequentially, in one system. This double technique provides a fluid, heterogeneous work environment, which differ from the other techniques that use only one viscoelastic substance and provide a fluid, homogeneous work environment.
