Abstract
An optical device for imaging an interior of an eye, especially a retina of the human eye, with the optical device including a front element which acts as an objective and which is adapted to be brought in proximity to the eye, and a single- or multi-element field lens disposed in a common mount. The mount and field lens each include a flattened surface portion extending substantially parallel to a common optical axis of the front element and field lens. The flattened surface portions are disposed so as to permit an introduction of a surgical instrument into the eye during eye surgery such as, for example, vitrectomy.
