ABSTRACT:
A device to be inserted within a lens capsule during ocular surgery to contain fluids, including therapeutic and optical materials, used for irrigation within the capsule is provided. The device includes a deformable membrane within a ring. One or more ports are provided for irrigation within the capsule. Reduced pressure in an area around the periphery of the membrane may be used for forming a sealing area between the device and the posterior surface of the capsule. Method for inserting the device into the capsule and performing irrigation or aspiration for polishing and for deforming the lens capsule is provided. The device may be placed in an eye for permanent isolation of fluids within the lens capsule from tissue and fluids outside the capsule.
