Abstract

A method and apparatus is provided for an intraocular device adapted for adjustment via a laser after implantation into an eye. The intraocular device is inserted into an eye, and one or more optical characteristics of the eye, including the intraocular device, are measured. Then, a groove configuration is determined for the intraocular device, and the configuration is ablated into the intraocular device with a short pulse laser.

Claims

1. A method of altering the optical characteristics of an intraocular device, said method comprising:

inserting said intraocular device into an eye;

measuring one or more optical characteristics of said eye, wherein said eye includes said intraocular device;

determining a groove configuration for said intraocular device; and

ablating with a short pulse laser said groove configuration into said intraocular device.

2. The method of claim 1, further comprising:

waiting for said eye to heal after inserting said intraocular device into said eye before measuring said one or more optical characteristics.

3. The method of claim 1, wherein said short pulse laser is selected from the group consisting of a picosecond laser, a femtosecond laser and an attosecond laser.

4. The method of claim 1, wherein said intraocular device is selected from the group consisting of a foldable lens and a hard lens.

5. The method of claim 1, wherein said intraocular device includes a material selected from the group consisting of a polymer, silicone and acrylic.

6. A method of altering the optical characteristics of a contact lens, said method comprising:

placing said contact lens on an eye;

measuring one or more optical characteristics of said eye and said contact lens;

determining a groove configuration for said contact lens; and

ablating with a short pulse laser said groove configuration into said contact lens.

7. The method of claim 6, wherein said short pulse laser is selected from the group consisting of a picosecond laser, a femtosecond laser and an attosecond laser.

8. The method of claim 6, wherein said contact lens is selected from the group consisting of a soft lens and a gas permeable lens.

9. The method of claim 6, wherein said contact lens includes a material selected from the group consisting of a polymer, silicone and acrylic.

10. A method of changing the optical properties of an optical system, said method comprising:

determining a groove configuration for a portion of said optical system, wherein said groove configuration causes a diffractive effect that improves the optical performance of said optical system; and

ablating with a short pulse laser said groove configuration into said portion.

11. The method of claim 11, wherein said portion is selected from the group consisting of an intraocular device, an intraocular lens, a natural lens, a contact lens, an eyeglass lens and a corrective lens.

12. A system for correcting the refractive error in an eye comprising:

an intraocular device suitable for insertion into the eye;

a short pulse laser; and

one or more grooves, wherein said one or more grooves are ablated into said intraocular device by said short pulse laser, and wherein said one or more grooves are configured to improve one or more optical characteristics of said eye.

13. The system of claim 12, wherein said short pulse laser is selected from the group consisting of a picosecond laser, a femtosecond laser and an attosecond laser.

14. The system of claim 12, wherein said intraocular device is selected from the group consisting of a foldable lens and a hard lens.

15. The system of claim 12, wherein said one or more grooves are positioned on said intraocular device such that at least some light passing through said pupil is diffracted by said one or more grooves.

16. The system of claim 12, wherein said grooves form substantially concentric circles.

17. The system of claim 12, wherein said intraocular device includes a material selected from the group consisting of a polymer, silicone and acrylic.

18. A system for correcting vision in an eye comprising:

a contact lens suitable for placement onto the eye;

a short pulse laser; and

one or more grooves, wherein said one or more grooves are ablated into said contact lens by said short pulse laser, and wherein said one or more grooves are configured to improve one or more optical characteristics of said eye and said contact lens.

19. The system of claim 18, wherein said short pulse laser is selected from the group consisting of a picosecond laser, a femtosecond laser and an attosecond laser.

20. The system of claim 18, wherein said contact lens is selected from the group consisting of a soft lens and a gas permeable lens.
