Safe all-in-the-bag pseudophakia with a new lens design (the moustache lens).

A classification of intraocular lenses is given that does justice to their clinical merits. There is a significant difference between a lens supported by cellular tissue and one supported by the collagen capsule of the crystalline lens. A new design of a wholly retropupillary lens for placement in the capsular bag ('moustache lens') is presented. The surgical technique is described in detail. The most important features of this lens are the ease of insertion and the guaranteed intracapsular and central position of the lens.
