Abstract

An artificial eye can include a body defining a cavity; a lens element disposed within the cavity; a cornea element positioned anteriorly of the lens element; and a liquid disposed within the cavity such that the liquid is positioned between the lens element and the cornea element. A method of simulating an ophthalmic procedure can include providing an artificial eye positioned in an optical path of light transmitted by an ophthalmic device and at least one of calibrating the ophthalmic device using the artificial eye; and operating on the artificial eye using the ophthalmic device.

First claim

The invention claimed is:

1. An artificial eye, comprising:
a body defining a cavity;
a lens element disposed within the cavity;
a cornea element positioned anteriorly of the lens element;
a liquid disposed within the cavity such that the liquid is positioned between the lens element and the cornea element; and
an attachment element coupled to the body, the attachment element configured to removably couple the body to an ophthalmic device.

2. The artificial eye of claim 1 , wherein:
the cornea element comprises a material selected to match at least one of the light scattering properties and the refractive index of a human cornea.

3. The artificial eye of claim 2 , wherein: the material includes at least one of hydrogel, silicone, glass, and clear plastic.

4. The artificial eye of claim 1 , wherein:
the attachment element includes an engagement feature to releasably retain the cornea element within the attachment element.

5. The artificial eye of claim 1 , further comprising:
a contact element coupled to the attachment element and disposed anteriorly of the cornea element.

6. The artificial eye of claim 1 , further comprising:
a sealing element disposed between the attachment element and the body.

7. The artificial eye of claim 1 , wherein:
the lens element comprises a material selected to match at least one of the light scattering properties and the refractive index of a human lens.

8. The artificial eye of claim 7 , wherein:
the second material includes at least one of hydrogel, silicone, glass, and clear plastic.

9. The artificial eye of claim 1 , wherein:
the lens element is coupled to a pedestal, wherein the pedestal is selectively movable relative to the body to selectively move the lens element relative to the cornea element.

10. The artificial eye of claim 9 , wherein:
the pedestal includes an engagement feature to releasably retain the lens element within the pedestal.

11. The artificial eye of claim 9 , further comprising:
a sealing element disposed between the pedestal and the body.

12. The artificial eye of claim 10 , further comprising:
an iris image disposed on an anterior surface of the engagement feature.

13. The artificial eye of claim 1 , further comprising:
a valve element configured to allow the liquid to flow into or out of the cavity.

14. The artificial eye of claim 13 , wherein the valve element includes at least one of:
a check valve and a soft membrane.

15. A method of simulating an ophthalmic procedure, comprising:
providing an artificial eye positioned in an optical path of light transmitted by an ophthalmic device, the artificial eye comprising
a body defining a cavity;
a lens element disposed within the cavity;
a cornea element positioned anteriorly of the lens element;
a liquid disposed within the cavity such that the liquid is positioned between the lens element and the cornea element; and
an attachment element coupled to the body, the attachment element configured to removably couple the body to the ophthalmic device; and

at least one of calibrating the ophthalmic device using the artificial eye; and operating on the artificial eye using the ophthalmic device.

16. The method of claim 15 , wherein calibrating the ophthalmic device includes:
calibrating an optical coherence tomography (OCT) system.

17. The method of claim 16 , wherein calibrating the ophthalmic device includes:
calibrating image characteristics of OCT images generated by the OCT system.

18. The method of claim 16 , wherein calibrating the ophthalmic device includes:
calibrating a depth of anatomy in OCT images generated by the OCT system.

19. The method of claim 15 , wherein operating on the artificial eye includes:
operating on the artificial eye using a laser system.

20. The method of claim 19 , wherein operating on the artificial eye includes:
making an incision in at least one of the lens element and the cornea element using the laser system.

21. The method of claim 20 , wherein making an incision includes:
applying a laser pulse to at least one of the lens element and the cornea element such that bubbles are formed in the liquid.

22. The method of claim 20 , further comprising:
removing at least one of the lens element and the cornea element from the artificial eye after the incision has been made such that the at least one of the lens element and the cornea element can be examined.

23. The method of claim 22 , further comprising:
installing at least one of a further lens element and a further cornea element in the artificial eye after removing the at least one of the lens element and the cornea element.
