Abstract

Claims (50)

1 . A device configured for insertion into an eye, the device comprising:

a base including:

an anterior portion having an anterior rim and an anterior opening, wherein the anterior rim includes a plurality of notches,

a posterior portion having a posterior rim and a posterior opening, and

an intermediate portion between the anterior and the posterior portions, wherein the intermediate portion is wider than the anterior and the posterior portions and protrudes from the anterior and the posterior portions, wherein the intermediate portion has an exterior that includes an anterior facing surface extending radially outward from the anterior portion and a posterior facing surface extending radially outward from the posterior portion, and wherein the intermediate portion has a recess therein,

wherein the recess is formed by an anterior ledge, a posterior ledge, and a sidewall extending in an anterior-posterior direction, and wherein the recess extends continuously around a circumference of the base,

wherein the posterior portion extends axially and circumferentially as a one piece continuous structure away from the intermediate portion to a proximalmost end of the posterior portion, and wherein a peripheral face of the posterior portion extends continuously around the posterior opening.

2 . The device of claim 1 , wherein the anterior portion further comprises:

an anterior wall; and

an anterior chamber posterior to the anterior rim and the anterior opening and radially surrounded by the anterior wall, wherein a width of the anterior chamber is greater than a diameter of the anterior opening.

3 . The device of claim 1 , wherein the posterior portion further comprises:

a posterior wall; and

a posterior chamber anterior to the posterior rim and the posterior opening and radially surrounded by the posterior wall, wherein a width of the posterior chamber is greater than a diameter of the posterior opening, and wherein the recess is spaced apart from the posterior opening by the posterior chamber.

4 . The device of claim 1 , wherein each of the anterior portion, the posterior portion, and the intermediate portion is annular.

5 . The device of claim 1 , wherein the recess is annular.

6 . The device of claim 1 , wherein the recess is wider than the anterior portion and the posterior portion.

7 . The device of claim 1 , further including a lens configured for receipt in the recess.

8 . The device of claim 1 , further comprising a pair of haptics extending radially outward from the intermediate portion.

9 . The device of claim 1 , wherein an outer diameter of the intermediate portion is about 8.5 mm.

10 . The device of claim 1 , wherein an inner diameter of the intermediate portion is about 7 mm.

11 . A device configured for insertion into an eye, the device comprising:

a base including:

a first portion including:

a first wall,

a first rim extending around an anterior side of the base, the first rim including a first opening at a first end of the first wall and a plurality of notches, and

a first chamber adjacent to the first opening, wherein a width of the first chamber is greater than a width of the first opening,

a second portion including a second rim extending around a posterior side of the base, the second rim including a second opening, and

an intermediate portion extending between the first and the second portions, wherein the intermediate portion is wider than the first and the second portions, wherein the intermediate portion has an exterior that includes an anterior facing surface extending radially outward from the first portion and a posterior facing surface extending radially outward from the second portion, and wherein the intermediate portion has a recess therein adjacent to the first chamber,

wherein the recess is formed by an anterior ledge, a posterior ledge, and a sidewall extending in an anterior-posterior direction, wherein the second portion extends axially and circumferentially as a one piece continuous structure away from the intermediate portion to a proximalmost end of the second portion, and wherein a peripheral face of the second portion extends continuously around the second opening.

12 . The device of claim 11 , wherein the first wall is angled radially inward, wherein a diameter of the first wall increases as the first opening approaches the intermediate portion.

13 . The device of claim 11 , wherein the second portion further includes:

a second wall; and

a second chamber adjacent to the second opening and radially surrounded by the second wall, wherein a diameter of the second chamber is greater than a diameter of the second opening.

14 . The device of claim 11 , wherein a radial wall thickness of the intermediate portion is less than an axial height of the base.

15 . The device of claim 11 , wherein the second portion further includes:

a second wall; and

a second chamber adjacent to the second opening and radially surrounded by the second wall, wherein a width of the second chamber is greater than a width of the second opening, and wherein the recess is spaced apart from the second opening by the second chamber.

16 . The device of claim 11 , wherein a width of the first wall increases as the first wall approaches the intermediate portion.

17 . The device of claim 11 , further including a lens configured for receipt in the recess.

18 . A device configured for insertion into an eye, the device comprising:

a base including:

an anterior housing portion having an anterior rim and an anterior opening, wherein the anterior rim includes a plurality of notches that provide access to a probe;

a posterior housing portion having a posterior rim and a posterior opening;

an intermediate housing portion between the anterior and the posterior housing portions, the intermediate housing portion having an exterior that includes an anterior facing surface extending radially outward from the anterior housing portion and a posterior facing surface extending radially outward from the posterior housing portion, the intermediate housing portion having a recess, wherein the recess is formed by an anterior ledge, a posterior ledge, and a sidewall extending in an anterior-posterior direction, wherein the recess extends continuously around a circumference of the base, wherein the posterior housing portion extends axially and circumferentially as a one piece continuous structure away from the intermediate housing portion to a proximalmost end of the posterior housing portion, and wherein a peripheral face of the posterior rim extends continuously around the posterior opening; and

a passage extending through the anterior housing portion, the posterior housing portion, and the intermediate housing portions; and

a lens configured for receipt in the intermediate housing portion, the lens including:

a central optic; and

a pair of tabs protruding radially outwardly from the central optic, wherein the tabs are configured to engage one or more surfaces of the intermediate housing portion.

19 . The device of claim 18 , wherein the pair of tabs includes a first fixed tab and a second actuatable tab.

20 . The device of claim 18 , wherein the tabs protrude from diametrically opposite locations of the central optic.
