Abstract

A system and method for performing an ocular surgical procedure is provided. The design maintains IOL temperature prior to implantation by assessing a desired IOL temperature, sensing existing IOL temperature, and maintaining the IOL substantially at the desired IOL temperature based at least in part on said existing IOL temperature. The method of maintaining desired IOL temperature involves comparing current IOL temperature with pre-established desired temperature conditions to determine a temperature change. The IOL is maintained substantially at the desired temperature based at least in part on the existing IOL temperature.

First claim

What is claimed is:

1. A method for regulating a temperature of an intra-ocular lens (IOL) during an ocular surgical procedure, said method accomplished using a computing device and comprising:
receiving desired IOL temperature information;
sensing IOL temperature conditions using a sensor, wherein said sensing comprises measuring actual temperature values associated with a fluid, wherein the IOL is contained in a wet fixture containing the fluid and the sensor;
comparing the first sensed IOL temperature conditions measured by the sensor with the desired IOL temperature, wherein said comparing results in a desired temperature change;
calculating a heating level for transferring an amount of heat required to achieve the desired temperature change; and
controlling an ocular surgical handpiece to transfer, via the fluid, heat to the IOL or to an IOL cartridge or an IOL insertion system containing the IOL, based on at least one operating parameter associated with the fluid,
wherein the ocular surgical handpiece comprises a needle, wherein the ocular surgical handpiece is positioned outside of the wet fixture and the needle is positioned within the wet fixture, and
wherein the IOL is maintained substantially at the desired temperature.

2. The method of claim 1 , wherein the IOL is maintained within a sterile field.

3. The method of claim 1 , wherein the ocular surgical handpiece comprises an electric diathermy connector using high frequency alternating electric or magnetic fields.

4. The method of claim 1 , wherein the receiving temperature information includes at least one selected from the group consisting of an IOL temperature profile and an IOL warming parameter.

5. The method of claim 1 further comprising:
displaying a system operating characteristic on a graphical user interface (GUI).

6. The method of claim 1 further comprising:
deriving a temperature setting based on the comparing results; and
storing the derived temperature setting.

7. The method of claim 6 , wherein the derived temperature setting includes a time parameter.

8. The method of claim 1 , wherein controlling heat transfer to the IOL is further based on the calculated heating level.

9. A method for regulating a temperature of an intra-ocular lens (IOL) during an IOL implantation procedure, said method accomplished using a computing device and comprising:
assessing a desired IOL temperature;
sensing an existing IOL temperature with a sensor, wherein the sensor is contained in a wet fixture and said sensing comprises measuring actual temperature values associated with a fluid contained in the wet fixture, the IOL being suspended in the fluid contained in the wet fixture;
comparing at least said assessed desired IOL temperature with said sensed existing IOL temperature to determine a desired temperature change;
calculating a heating level for transferring an amount of heat required to achieve the desired temperature change, wherein the calculated heating level is based on an operating room personnel selected input parameter associated with the fluid; and
applying the calculated heating level to regulate the IOL, via the fluid contained in the wet fixture, substantially at the desired IOL temperature by controlling heat transfer from an ocular surgical handpiece to the IOL, wherein the ocular surgical handpiece comprises a needle, wherein the ocular surgical handpiece is positioned outside of the wet fixture and the needle is positioned within the wet fixture.

10. The method of claim 9 , wherein said comparing comprises comparing one or more IOL temperature conditions measured by a sensor with pre-established desired temperature conditions.

11. The method of claim 9 , wherein said applying further comprises selectively controlling the ocular surgical handpiece to transfer heat from the ocular surgical handpiece to the IOL.

12. The method of claim 11 , wherein said ocular surgical handpiece employs a heating element to heat the fluid contained in the wet fixture.

13. The method of claim 9 , wherein said applying further comprises selectively refraining from transferring heat to the IOL when the desired temperature change is within predefined parameters.

14. The method of claim 9 , wherein the IOL is maintained within a sterile field.

15. The method of claim 9 , wherein heat is transferred from an electric diathermy connector using high frequency alternating electric or magnetic fields.

16. The method of claim 9 , wherein the ocular surgical handpiece is an ultrasonically driven phacoemulsification handpiece.

17. The method of claim 9 further comprising:
displaying a system operating characteristic on a graphical user interface (GUI).

18. The method of claim 9 further comprising:
deriving a temperature setting based on the comparing results; and
storing the derived temperature setting.

19. The method of claim 18 , wherein the derived temperature
setting includes a time parameter.
