Abstract

Embodiments of this invention generally relate to systems and methods for wavefront interactive refraction display and more particularly to systems and methods for capturing and displaying eye wavefront interactive refraction data based on the desired refractive state of the patient's eye.

First claim

What is claimed is:

1. A method, comprising:
a scanning engine repeatedly collecting data, at a first resolution, indicative of a refractive state of a patient's eye over a period of time;
repeatedly ascertaining a current refractive state of the patient's eye from the repeatedly collected data indicative of the refractive state of the patient's eye;
continuously displaying an indication of the current refractive state of the patient's eye, the displayed indication of the current refractive state being continuously variable with time;
while displaying the indication of the current refractive state of the patient's eye, receiving from a user or the patient a command to capture additional data indicative of the refractive state of the patient's eye; and
in response to the command, the scanning engine capturing additional data, at a second resolution, indicative of the refractive state of the patient's eye, wherein the second resolution is greater than the first resolution; and
ascertaining a final refractive state of the patient's eye from the captured additional data indicative of the refractive state of the patient's eye.

2. The method of claim 1 , wherein the data indicative of the refractive state of the patient's eye is wavefront data sensed by a Shack-Hartmann wavefront sensor.

3. The method of claim 1 , further comprising providing an accommodation aid to the patient while the scanning engine repeatedly collects, at the first resolution, data indicative of the refractive state of the patient's eye.

4. The method of claim 1 , further comprising, while displaying the indication of the current refractive state of the patient's eye:
receiving a task request from the user or the patient; and
in response to the received task request, providing an indicator of a first patient task to be performed by the patient.

5. The method of claim 4 , further comprising receiving a patient input in response to the first patient task to be performed.

6. The method of claim 4 , further comprising displaying to the patient a target with a changing property.

7. The method of claim 6 , wherein the indicator of the first patient task includes a request for a patient input in response to the changing property of the target.

8. The method of claim 6 , wherein the changing property includes one of:
changing a brightness of at least a portion of the target;
changing a color of at least a portion of the target;
changing a clarity of at least a portion of the target;
changing an image of the target; and
changing a size of the target.

9. The method of claim 4 , further comprising:
receiving a second task request from the user or the patient; and
in response to the received second task request, providing an indicator of a second patient task to be performed by the patient, the second patient task being different than the first patient task.

10. The method of claim 1 , wherein the final refractive state of the patient's eye is ascertained with greater accuracy from the captured additional data indicative of the refractive state of the patient's eye than the current refractive state of the patient's eye is ascertained from the collected data indicative of the refractive state of a patient's eye.

11. A system, comprising:
a patient interface configured to display a target to a patient;
a scanning engine configured to obtain data indicative of a refractive state of a patient's eye;
a display device; and
a processor configured to:
cause the scanning engine to repeatedly collect data, at a first resolution, indicative of the refractive state of the patient's eye over a period of time;
repeatedly ascertain a current refractive state of the patient's eye from the repeatedly collected data indicative of the refractive state of the patient's eye;
cause the display device to continuously display an indication of the current refractive state of the patient's eye, the displayed indication of the current refractive state being continuously variable with time;
while displaying the indication of the current refractive state of the patient's eye, receive from a user or the patient a command to capture additional data indicative of the refractive state of the patient's eye; and
in response to the command, cause the scanning engine to capture additional data, at a second resolution, indicative of the refractive state of the patient's eye, wherein the second resolution is greater than the first resolution; and
ascertain a final refractive state of the patient's eye from the captured additional data indicative of the refractive state of the patient's eye.

12. The system of claim 11 , wherein the display device is included in the patient interface.

13. The system of claim 11 , further comprising a user interface distinct from the patient interface, wherein the display device is included in the user interface.

14. The system of claim 11 , wherein the processor is configured to receive the command to capture additional data indicative of the refractive state of the patient's eye via the patient interface.

15. The system of claim 11 , further comprising a user interface distinct from the patient interface, wherein the processor is configured to receive the command to capture additional data indicative of the refractive state of the patient's eye via the user interface.

16. The system of claim 11 , wherein the scanning engine includes a Shack-Hartmann wavefront sensor.

17. The system of claim 11 , wherein the processor is further configured to cause the patient interface to provide an accommodation aid to the patient while the scanning engine repeatedly collects, at the first resolution, data indicative of the refractive state of the patient's eye.

18. The system of claim 11 , wherein the processor is further configured to, while the display device displays the indication of the current refractive state of the patient's eye:
receive a task request from the user or the patient; and
in response to the received task request, provide an indicator of a patient task to be performed by the patient.

19. The system of claim 18 , wherein the processor is further configured to cause the patient interface to display to the patient the target with a changing property.

20. The system of claim 19 , wherein the indicator of the patient task includes a request for a patient input in response to the changing property of the target.
