Title (EN) EXPANDABLE LENS REPLACEMENT
(FR) REMPLACEMENT DE LENTILLE OCULAIRE
Abstract:
(EN) A method and apparatus for implanting synthetic lenses into a human eye (E) in which the capsular bag (AC, PC) is first evacuated of the natural lens substance (LS) and thereafter a peripheral spreader (55, 155, 156) is inserted into the evacuated capsular bag (AC, PC) within which an expandable lens sack (50, 165) is received. In one alternative the spreader (55) forms the exterior position of the lens and is thus inserted as a collapsed structure into the capsular bag (AC, PC) and in the other alternative the spreader (155, 156) comprises a plurality of arcuate segments (155, 156) expelled through a needle into the lens capsule (AC, PC).
(FR) Un procédé et un dispositif d'implantation de lentilles synthétiques dans l'÷il humain (E) où le sac capsulaire (AC, PC) est d'abord évacué de la substance naturelle formant lentille (LS) et, ensuite, un dilatateur périphérique (55, 155, 156) est inséré dans le sac capsulaire évacué (AC, PC) qui reçoit une lentille expansible (50, 165). Dans l'une des variantes, le dilatateur (55) forme la position extérieure de la lentille et est ainsi inséré en tant que structure comprimée dans le sac capsulaire (AC, PC) et, dans l'autre variante, le dilatateur (155, 156) comprend une pluralité de segments en forme d'arc (155, 156) expulsés par une aiguille dans la lentille capsulaire (AC, PC).
