A sleeve apparatus (25) for use in combination with a surgical instrument for the removal of a cataract through an incision in a patient's eye. The sleeve apparatus includes a first sleeve member (30) having an interior longitudinal bore through which at least a portion of the surgical instrument is insertable. A second sleeve member (40), substantially concentric to and operatively attached to an outer surface of the first sleeve member, substantially surrounds a portion of the first sleeve member to create a chamber (42) for receipt of expansion material therebetween. The second sleeve member is resilient and expansile in circumference due to the presence of expansion material within the chamber, so as to substantially conform to the shape of the incision and/or the interior of the wound and substantially seal the incision and reduce the loss of fluid from the patient's eye during surgery.

Manchon (25) destiné à être utilisé conjointement avec un instrument chirurgical pour ôter un cristallin cataracté par une incision dans l'oeil d'un patient. Le manchon comprend un premier élément de manchon (30) présentant un orifice longitudinal intérieur à travers lequel on peut insérer au moins une partie de l'instrument chirurgical. Un second élément de manchon (40), sensiblement concentrique par rapport à une surface extérieure du premier élément de manchon et fixé fonctionnellement à celle-ci, entoure sensiblement une partie du premier élément de manchon afin de créer une chambre (42) destinée à recevoir une matière de dilation entre lesdits éléments. Le second élément de manchon est souple et dilatable en circonférence du fait de la présence d'une matière de dilation à l'intérieur de la chambre, de manière à s'adapter sensiblement à la forme de l'incision et/ou à l'intérieur de la lésion, d'obturer sensiblement l'incision et de réduire les pertes de fluide depuis l'oeil du patient pendant l'opération chirurgicale.
