Microscopes with a noncontact wide-angle viewing scope are used during surgeries on the eye, wherein an electromotively adjustable optic is provided between the lens and the eye. In order to prevent the surgeon from interrupting the surgery in order to refocus and to allow the electromotive drive to be maintained in a sterile condition, the drive is provided above the lens and is rotatably connected to an adjusting gear for the optic by means of a flexible drive shaft which can be released from the drive.
