Abstract
There is described a method for the removal of a contact lens (30) from a container (10), with a contact lens (30) being immersed in a liquid (20) which is held in a container (10), and the contact lens (30) being removed from the container (10) together with at least a portion of the liquid (20) through a removal tube (3) which is dipped into the liquid (20) within the container (10). First the container (10) containing the liquid (20) and the immersed contact lens (30) is closed pressure-tight with a lid (2), which comprises the removal tube (3) and a pressure tube (5). Both, the removal tube (3) and the pressure tube (5), are guided through the lid (2). After the closing of the container (10) with the lid (2) an overpressure is applied to the interior of the closed container (10) through the pressure tube (5). The overpressure is applied such that the contact lens (30) and the liquid (20) are pressed into the removal tube (3) and removed together therethrough. There is also described a device (1) for carrying out the method.
