An opthalmologic lens insertion device that holds a lens between a pair of leaf springs and has a plunger that moves between the leaf springs to eject the lens onto the cornea or into a corneal pocket. The resultant gel is milled in a colloid mill, and if desired, diluted to a concentration of about 3% to about 8% with a diluent selected from the group consisting of low viscosity silicone oil, hydrocarbon oil, lower alkanol, or mixtures thereof. The retainer has a chamfered top flange along its top edge, a circumferential bulge area around its outer surface approximately in the middle of its length, and a base at the bottom. The connecting leads are arranged in a fan configuration. The dispenser may act as an electromechanical patch, capable of long term administration of drugs to the skin, to achieve local or systemic pharmaceutical effects. The nodes may communicate by emitting and receiving the data light, which may be analyzed by the controller.
