Abstract

An intraocular lens (IOL) punch includes a handpiece having an opening at a first end, a jaw comprising a first leg and a second leg joined at a first rod end of a rod, the rod extending into the opening and moveable relative to the handpiece to operate the jaw between an open position and a closed position, and a post attached to the first leg and extending toward the second leg, wherein in the open position there is a gap between the post and the second leg and in the closed position the post extends to the second leg closing the gap.

Claims (29)

1 . A method comprising:

using a punch to create a hole in an intraocular lens (IOL), the punch comprising a jaw having a first leg and a second leg joined at a first rod end of a rod, the rod extending into an opening in a handpiece and moveable relative to the handpiece to operate the jaw between an open position and a closed position, and a post attached to the first leg and extending toward the second leg, wherein in the open position there is a gap between the post and the second leg and in the closed position the post extends to the second leg closing the gap;

placing a portion of the IOL in the gap;

moving the jaw to the closed position thereby creating the hole in the IOL;

opening the jaw; and

removing the IOL from the gap.

2 . The method of claim 1 , further comprising securing the IOL in an eye with a suture passing through the hole.

3 . The method of claim 1 , wherein the moving the jaw to the closed position comprises moving the jaw into the opening of the handpiece.

4 . The method of claim 1 , wherein the moving the jaw to the closed position comprises manually moving the jaw toward the handpiece.

5 . The method of claim 1 , comprising positioning the jaw through a corneal incision in an eye; and

creating the hole with the IOL located in the eye.

6 . The method of claim 5 , further comprising securing the IOL in the eye with a suture passing through the hole.

7 . The method of claim 6 , wherein the IOL is secured to a sclera with the suture.

8 . The method of claim 5 , wherein the hole is created in a haptic-optic junction of the IOL.

9 . The method of claim 8 , wherein the IOL is secured to a sclera with the suture.

10 . The method of claim 8 , wherein the moving the jaw to the closed position comprises manually moving the jaw toward the handpiece.

11 . The method of claim 1 , further comprising an actuator coupled with the handpiece and the rod, the actuator operable to move the rod relative to the handpiece.

12 . The method of claim 11 , wherein the actuator is an electric motor.

13 . The method of claim 11 , wherein the actuator is a handle manually operable to move the rod.

14 . The method of claim 1 , wherein the second leg comprises an aperture and the post extends into the aperture when the jaw is in the closed position.

15 . The method of claim 1 , further comprising an actuator coupled with the handpiece and the rod, the actuator operable to move the rod relative to the handpiece; and

the second leg comprising an aperture, wherein the post extends into the aperture when the jaw is in the closed position.

16 . The method of claim 15 , further comprising:

positioning the jaw through a corneal incision in an eye; and

creating the hole with the IOL located in the eye.

17 . The method of claim 16 , further comprising securing the IOL in the eye with a suture passing through the hole.

18 . The method of claim 17 , wherein the IOL is secured to a sclera with the suture.

19 . The method of claim 16 , wherein the hole is created in a haptic-optic junction of the IOL.

20 . The method of claim 19 , wherein the IOL is secured to a sclera with the suture.
