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 for identifying a time for capturing eye refraction data, the method comprising:
(a) continuously sensing a waveform of light passing through a patient's eye over a period of time, wherein the waveform is affected by an optical property of the patient's eye;
(b) continuously calculating a refractive state of the patient's eye with the sensed waveform;
(c) continuously displaying an indication of a current refractive state of the patient's eye, the displayed indication of the current refractive state being continuously variable with time;
(d) while displaying the indication of the current refractive state of the patient's eye, receiving a task request from a user or the patient via an interface device; and
(e) in response to the received task request, displaying a target with a changing property and an indicator of a patient task to be performed by the patient, while continuously displaying the indication of a current refractive state of the patient's eye.

2. The method of claim 1 , wherein the changing property of the target includes one of:
brightness of the target;
a color of the target;
clarity of the target;
an image of the target; and
a size of the target.

3. The method of claim 1 , wherein the indicator of the patient task includes a request for a patient input in response to the changing property of the target.

4. The method of claim 3 , further comprising:
(f) receiving the patient input corresponding to the patient task.

5. The method of claim 4 , further comprising:
while displaying the indication of the current refractive state of the patient's eye, receiving, from a user or the patient via an interface device, a command to capture eye refraction data of the patient's eye; and
capturing eye refraction data in response to the received command.

6. The method of claim 4 , further comprising:
repeating steps (d), (e) and (f) for additional patient tasks;
aggregating data indicative of the refractive state of the patient's eye; and
correlating the data indicative of the refractive states of the patient's eye with the tasks.

7. The method of claim 6 , further comprising:
identifying maximums and minimums in the aggregated data indicative of the refractive state of the patient's eye; and
identifying tasks associated with the minimums and maximums in the aggregated data.

8. The method of claim 6 , further comprising:
providing an indicator of one or several tasks associated with desired refractive states of the patient's eye.

9. A system for identifying a time for capturing eye refraction data, the system comprising:
a patient interface configured to display a target to a patient and to sense the properties of a waveform passing through the patient's eye; and
a processor configured to:
(a) direct the patient interface to continuously sense the waveform of light passing through the patient's eye over a period of time, wherein the waveform is affected by an optical property of the patient's eye;
(b) continuously calculate a refractive state of the patient's eye;
(c) continuously provide an indication of a current refractive state of the patient's eye, the indication of the current refractive state being continuously variable with time;
(d) while displaying the indication of the current refractive state of the patient's eye, receive a task request from a user or the patient via an interface device; and
(e) in response to the received task request, display a target with a changing property and an indicator of a patient task to be performed by the patient, while continuously displaying the indication of a current refractive state of the patient's eye.

10. The system of claim 9 , wherein the changing property of the target includes one of:
brightness of the target;
a color of the target;
clarity of the target;
an image of the target; and
a size of the target.

11. The system of claim 9 , wherein the indicator of the patient task includes a request for a patient input in response to the changing property of the target.

12. The system of claim 11 , wherein the processor is further configured to:
(f) receive the patient input corresponding to the patient task.

13. The system of claim 12 , wherein the processor is further configured to:
while displaying the indication of the current refractive state of the patient's eye, receive, from a user or the patient via an interface device, a command to capture eye refraction data of the patient's eye; and
capture eye refraction data in response to the received command.

14. The system of claim 9 , wherein the processor is further configured to:
repeat steps (d), (e) and (f) for additional patient tasks;
aggregate data indicative of the refractive state of the patient's eye; and
correlate the data indicative of the refractive states of the patient's eye with the tasks.

15. The system of claim 9 , wherein the processor is further configured to:
identify maximums and minimums in the aggregated data indicative of the refractive state of the patient's eye; and
identify tasks associated with the minimums and maximums in the aggregated data.

16. The system of claim 9 , wherein the processor is further configured to:
provide an indicator of one or several tasks associated with desired refractive states of the patient's eye.
