The uvea-touch syndrome and how to avoid it. Personal thoughts about lens implantation.

For successful lens implantation, the quality of the cataract extraction needed to be improved. The debate whether to perform extracapsular or intracapsular extraction has not yet come to an end. For better understanding a classification of lenses is necessary in view of the clinical consequences. The contact of the lens with the eye (read: the site of lens support) determines the long-term fate of an eye with a lens. All lenses in contact with uveal tissue may cause symptoms that together constitute the uvea-touch syndrome. Capsular support is to be preferred over uvea-support. The all-in-the-bag position of a lens is superior. This can be achieved with so-called inter-capsular surgery. A new lens design that is adapted to inter-capsular surgery is presented and its use described in detail (the 'Moustache' lens). There are few restrictions to its use.
