S mm. A silicone ring, with a diameter Of 14 mm and with the same curve as the contact lens, provides a perfect fixation on the eye and prevents the air bubbles between lens and eye (Fig. 12). The membrane peeler (Fig. 13) is a blunt instrument which, among other things, is therefore suitable for explorative work among retinal folds, where one often has to separate the retina from the membranes without good visibility.

A PDMS with an average MW of 30,000 and a viscosity of 5,000 mPa's. Another way of varying viscosity is to mix two different PD MSs; this results in an intermediate viscosity corresponding to the newly created average MW. This is reflected in a quite asymmetrical distribution ofMWs (Fig. 4), meaning that PDMSs of equal viscosity are fully capable of having different MW distributions. The polymerization of SO is a chemical process which leads to a statistical distribution of the length of the polymerized molecules and in that way their MW.
