Abstract
An interior bag for a capsular bag of an eye comprises a discriminatingly permeable interior bag that selectively reduces fluid flow volume through the interior bag. The interior bag is secured inside the capsular bag. A structure, adapted to hold a refractive device, is attached to the interior bag.
Claims31
An apparatus to protect an eye, comprising:
- an interior bag having a non-uniform thickness forming a contoured outer surface having protrusions configured to engage an inner surface of a capsular bag of an eye and having portions configured to avoid engagement with the inner surface of the capsular bag that allow a reduced fluid flow between the inner surface of the capsular bag and the contoured outer surface of the interior bag in a manner reducing a probability of posterior capsular opacification in the eye, said interior bag optionally further configured to contain a refractive device.
An apparatus to support a capsular bag in an eye, comprising:
- an interior bag, configured to occupy a substantial portion of a volume of a capsular bag in the eye, defining an undivided main chamber and at least one secondary chamber between which fluid flows during accommodation within the eye, said main chamber being adapted to receive an injectable refractive device,
- wherein the undivided main chamber and the at least one secondary chamber are formed within the interior bag, and
- wherein the interior bag provides a contoured outer surface configured to inhibit a free flow of aqueous humor through the capsular bag.
An apparatus for placement in a capsular bag of an eye, comprising:
- an interior bag configured to occupy a substantial portion of a volume of a capsular bag in the eye, the interior bag having an exterior contour structurally biologically-compatible with the capsular bag of the eye, wherein the interior bag includes a contoured outer surface configured to inhibit a free flow of aqueous humor through the capsular bag;
- the interior bag comprising an undivided main chamber and at least one annular chamber having a semi-permeable wall section configured to provide a time-released passage of a fluid to the undivided main chamber of the capsular bag,
- wherein the undivided main chamber and the at least one annular chamber are formed within the interior bag.
An apparatus to protect a capsular bag in an eye, comprising:
- an interior bag having a non-uniform thickness forming a contoured outer surface having protrusions configured to engage an inner surface of a capsular bag of an eye and having portions configured to avoid engagement with the inner surface of the capsular bag that allow a reduced fluid flow between the inner surface of the capsular bag and the contoured outer surface of the interior bag, and
- defining an undivided main chamber and at least one secondary chamber between which fluid flows during accommodation within the eye, said main chamber being adapted to receive an injectable refractive device,
- wherein the undivided main chamber and the at least one secondary chamber are formed within the interior bag.
