An intraocular lens for insertion into a capsular bag of an eye comprises: an optic; and at least one plate haptic coupled to the optic by one or more flexible connecting members. The plate haptic with flexible finger extensions is designed to engage the periphery of the capsular bag. An increase in radial pressure upon constriction of the ciliary muscle causes the rigid posteriorly vaulted plate haptics to move centrally to further increase the vitreous cavity pressure with constriction of the ciliary muscle: the optic with its thin stretchable hinge across the connecting member is then displaced anteriorly along the axis of the eye. The haptic includes a longitudinally rigid frame to restrict deformation of the haptic in a longitudinal direction while permitting deformation in a transverse direction. Furthermore, the flexible connecting members include one or more hinged straps that extend radially and/or longitudinally from the optic. The optic can move forwards and backwards, relative to both the distal and proximal ends of the plate haptics, in response to ciliary muscle contraction and relaxation with an increase and decrease of vitreous cavity pressure. Finger-like projection extends from the plate haptic to engage the capsular bag to center and fixate the accommodating lens within the capsular bag.

Finger extensions for astronaut gloves are disposed in sleeves on digits of the gloves. Different embodiments for the extensions are illustrated and discussed. The sleeves are secured to the tops of the digits. The extension elements include bases disposed in the sleeves and tips at outer ends of the bases. The tips may include pads which contact elements desired to be manipulated. The extensions are pivotal with the movement of the astronaut's digits in a glove. Only a slight movement of the astronaut's digits is required to provide the required dexterity for the astronaut user to grasp, pick up, move, etc., desired elements with the extensions. Inflexible rings about the extensions are fixed to the gloves prevent reverse bending of the extensions and maintain the extensions generally parallel to the users fingers. The extensions may be fixed or extendable and retractable, as desired. Particular designs for the extensions may depend on the desired task for the astronaut or astronauts and the elements with which the astronaut(s) will be working.

The invention discloses a prosthesis mechanical arm, a robot and a robot control method.
