Abstract: An intraocular lens (10) is provided for implantation into the posterior chamber of the eye following extracapsular cataract surgery. The lens body (12) includes a convex posterior surface having an optic area positioned in direct apposition to the posterior capsular membrane. The curvature of the posterior surface of the lens is fixed and power modifications are made by changing the curvature of the anterior optical surface of the lens body. The circumferential edge of the lens body is angled posteriorly to provide an annular space outside the optic area of the lens for laser or knife surgery frequently necessary after the lens implantation by extra capsular technique. In another embodiment, the intraocular lens is provided with a haptic (14,16) having a proximal portion extending anteriorly from the intraocular lens and a distal portion constructed to lie in substantially parallel relation to the iris. Upon contraction and relaxation of the ciliary muscle, the haptic urges the intraocular lens posteriorly or anteriorly rather than causing lateral movement of the lens on the posterior capsular membrane.

Abstract: On décrit une méthode pour sécher l'air à l'aide d'un rotor (6) qui tourne continuellement dans une enveloppe (2) et qui contient des moyens d'absorption d'humidité. L'enveloppe (2) contient un boîtier qui est situé sur le côté basse pression du rotor et muni de dispositifs d'émission de chaleur, par exemple, des éléments électriques (15) pour fournir de la chaleur radiante directement à l'intérieur du rotor. La chaleur nécessaire à la régénération est fournie à haute température à celui-ci, ce qui augmente le rendement de la chaleur. La partie du rotor (7) qui est normalement la plus difficile à régénérer est ainsi réchauffée à une température de 250-300°C. Puisque le volume d'air de régénération est beaucoup plus faible que la normale, l'air est chauffé à une température qui est beaucoup plus élevée que la normale dans toutes les parties du rotor, ce qui a pour effet d'éliminer de façon efficace l'humidité présente. L'invention concerne également un appareil pour sécher l'air au moyen duquel peut s'effectuer la réalisation de la méthode.
