Viscoelastics: Medical Device or Drug, Medizinproduktegesetz, 1994) are not drugs in the AMG sense of the word. MPG medicinal products, as defined in §3 are those substances whose main effect is neither pharmacological, immunological, nor metabolic.

group of substances has enlarged the field of ophthalmic surgery enormously. Many procedures have be- come safer and simpler and other techniques could only be developed because of the availability of visco elastics. Especially cataract surgery and implantation of intraocular lenses have benefitted.

Viscoelastic Substances,ular level, sodium hyaluronate is involved in intercellular interactions, cell matrix adhesions, cell mobility and extracellular organization. It also accelerates wound healing (Abatangelo, Martelli & Vecchia, 1983; Arzeno & Miller, 1982) and seems to function as a natural biological substance.

Complications Through the Use of Viscoelastics, by Davison in 1990. Miyake et al. proposed a new classification of capsular block syndrome and supposed viscoelastic material to cause early-postoperative capsular block syndrome (Miyake et al., 1999). Capsular bag distension after optic capture of a sulcus-fixated IOL was described by Basti et al. (1999).

Special Uses of Viscoelastics,hat aqueous is permitted to flow out.When using a paracentesis to inject viscoelastic (Fig. 59), it must be big enough toallow aqueous outflow. For complete aqueous exchange in the anterior chamber,it is advisable to inject the viscoelastic into the opposite chamber angle.

Overview,operations. The number of cataract operations has been rising steadily, worldwide, since the introduction of IOL implantation. In 1999, 430 000 cataract operations were performed in Germany alone, thus establishing cataract operations as the most frequently performed surgical procedure.

Basics,pany recommendations in their selection of a suitable agent. Manufacturer information is based on substance testing conducted by different institutes and sometimes reveals inconsistencies. The physicochemical characteristics must fulfill practical criteria which are essential for every-day operative use:
