title: [The use of a viscous substance (Healon) to improve tactility (author's transl)].
abstract: Now that a clinically suitable viscous substance (Healon) has become available for use in ophthalmic surgery, it is worthwhile to examine in greater depth the problems of tactility and methods of resolving them with viscous substances. These are not simple substitutes for aqueous humor which, once introduced, may be left in the eye. It is more appropriate to compare them with mechanical instruments employed for a specific purpose and subsequently removed. Thanks to their stabilizing effect, viscous substances increase safety in many types of manipulation. However, their use calls for a thorough knowledge of their side-effects. This has to be learned, as is the case with any new instrument.
