Abstract

Modular IOL systems including a base and a lens, wherein the lens includes fixed and actuatable tabs for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or post-operatively. Drug delivery capabilities and/or sensing capabilities may be incorporated into the base. Injector devices may be used to facilitate placement of the base and the lens sequentially or simultaneously into the eye.

First claim

We claim:

1. A device configured for insertion into an eye, the device comprising:
a base comprising:
an anterior section surrounding an anterior opening, wherein the anterior section has a posterior surface;
a posterior section surrounding a posterior opening, wherein the posterior section has an anterior surface;
an in-ward facing lateral wall extending between the anterior and the posterior sections; and
a passage extending through the device from the anterior opening to the posterior opening;

wherein a first angle is formed by an anterior end of the in-ward facing lateral wall and the posterior surface of the anterior section and a second angle is formed by a posterior end of the in-ward facing lateral wall and the anterior surface of the posterior section; and a lens including at least one tab configured to be received between the first angle and the second angle of the base, wherein the at least one tab has a thickness that corresponds to an anterior-posterior dimension defined by a distance between the anterior end and the posterior end of the in-ward facing lateral wall of the base.

2. The device of claim 1 , wherein the first angle is an obtuse angle.

3. The device of claim 1 , wherein the anterior opening is wider than the posterior opening.

4. The device of claim 1 , wherein an equatorial diameter of the base is about 8.5 mm.

5. The device of claim 1 , wherein an axial thickness measured between an anterior surface of the anterior section and a posterior surface of the posterior section is between approximately 1 mm and 2.5 mm.

6. The device of claim 1 , wherein the anterior section includes a radially inner surface extending from an anterior surface to the posterior surface of the anterior section.

7. The device of claim 1 , wherein the at least one tab includes a fixed tab.

8. The device of claim 7 , wherein the in-ward facing lateral wall has a linear geometry that matches an outer-most wall of the at least one tab.

9. A device configured for insertion into an eye, the device comprising:
a base, the base comprising:
an anterior section surrounding an anterior opening, wherein the anterior section has a posterior surface;
a posterior section surrounding a posterior opening, wherein the posterior section has an anterior surface;
an in-ward facing lateral wall extending between the anterior and the posterior sections; and
a passage extending through the device from the anterior opening to the posterior opening;

wherein a first angle is formed by an anterior end of the in-ward facing lateral wall and the posterior surface of the anterior section and a second angle is formed by a posterior end of the in-ward facing lateral wall and the anterior surface of the posterior section; and
a lens configured for insertion into and removal from the base, the lens comprising:
an optic portion; and
at least one tab, wherein the at least one tab has a thickness that corresponds to an anterior-posterior dimension defined by a distance between the anterior end and the posterior end of the in-ward facing lateral wall of the base.

10. The device of claim 9 , wherein the in-ward facing lateral wall of the base has a linear geometry that matches an outer-most wall of the at least one tab.

11. The device of claim 9 , wherein the base is annular.

12. The device of claim 9 , wherein a ratio of an axial thickness of the base to a diameter of the base is between approximately 0.12 and 0.29.

13. The device of claim 9 , wherein an axial thickness of the base is at least approximately 1 mm.

14. The device of claim 13 , wherein an axial thickness of the base is between approximately 1 mm and 2.5 mm, and wherein a diameter of the base is approximately 8.5 mm.

15. The device of claim 9 , wherein an overall volume of the device is approximately 67 mm 3 .

16. A device configured for insertion into an eye, the device comprising:
a base, the base comprising:
a pair of haptics;
an anterior section surrounding an anterior opening, wherein the anterior section has a posterior surface;
a posterior section surrounding a posterior opening, wherein the posterior section has an anterior surface;
an in-ward facing lateral wall extending between the anterior and the posterior sections;
a passage extending through the device from the anterior opening to the posterior opening; and
an intermediate section surrounding the passage,
wherein the intermediate section comprises a first angle formed by an anterior end of the in-ward facing lateral wall and the posterior surface of the anterior section and a second angle formed by a posterior end of the in-ward facing lateral wall and the anterior surface of the posterior section; and a lens configured for insertion into the base, the lens including at least one tab received in the intermediate section of the base, wherein the at least one tab has a thickness that corresponds to an anterior-posterior dimension defined by a distance between the anterior end and the posterior end of the in-ward facing lateral wall.

17. The device of claim 16 , wherein the intermediate section has an opening dimension defined by a distance between the anterior section and the posterior section along an inner diameter of each of the anterior section and the posterior section, and wherein the opening dimension of the intermediate section is greater than a thickness of the at least one tab.

18. The device of claim 17 , wherein the opening dimension of the intermediate section is at least 1.5 times greater than thickness of the at least one tab.

19. The device of claim 17 , wherein the at least one tab has an outside curvature configured to conform to a surface of the intermediate section.

20. The device of claim 1 , wherein the at least one tab includes a tab having a hole.
