Abstract

A lens element and a one-piece contact apparatus having a lens element and a holding device for fixing a patient's eye to a laser applicator of an ophthalmological laser therapy system and a corresponding production method. The production method is conceptually simple and user-friendly and allows a high degree of automation while at the same time meeting the high requirements for mechanical and optical precision of the lens element. The lens element has an optically effective zone and a joining zone. The joining zone also has a functional zone for joining the lens element to a holding device which is arranged continuously circumferentially or interrupted circumferentially at the outer edge of the lens element. The contact apparatus includes a lens element and a holding device, which are permanently connected to one another, wherein the lens element and the holding device are not connected to one another by adhesive-bonding.
