## Abstract

A voice control system for ophthalmologic laser treatment systems sets parameters for delivering laser energy based on voice commands and prevents potentially harmful parameters due to operator mistakes and misunderstood voice commands by providing incremental parameter adjustment and restricting the amount by which the parameters can be adjusted for each executed voice command. Valid voice commands include indications of which parameter to set, a value for the parameter, and whether to increase or decrease the value of the parameter. In one example, parameter values can only be increased or decreased by a certain percentage with respect to the current value. In another example, the parameters are adjusted by selecting the next highest or lowest value with respect to the current parameter value from a predetermined sequence of possible values for particular parameters. Voice control functionality can also be deactivated under certain conditions such as when it is determined that a parameter was not set.

## Claims

### Claim 1

A system for delivering laser energy to an eye of a patient, the system comprising:
a microphone for capturing audio data;
a voice control module for receiving the captured audio data and generating voice command information based on the captured audio data by recognizing spoken language indicating whether current values for parameters should be incrementally increased or decreased;
a parameter regulation module for generating parameter information based on the voice command information; and
a control module for receiving the parameter information and setting parameters for the delivered laser energy based on the parameter information.

### Claim 2 (depends on 1)

The system of claim 1, wherein the voice control module generates the voice command information by recognizing spoken language identifying the parameters for which the current values should be incrementally increased or decreased.

### Claim 3 (depends on 1)

The system of claim 1, wherein the microphone captures the audio data in response to detecting a predetermined wake word.

### Claim 4 (depends on 1)

The system of claim 1, further comprising speakers for providing audible feedback confirming the parameter information and/or the voice command information.

### Claim 5 (depends on 1)

The system of claim 1, wherein the laser energy is delivered to the eye of the patient by a body-mounted laser-indirect ophthalmoscope (LIO) system, a table-top LIO system, or a slit-lamp device.

### Claim 6 (depends on 1)

The system of claim 1, wherein the parameter regulation module generates the parameter information based on the current values for the parameters and a predetermined safety policy.

### Claim 7 (depends on 1)

The system of claim 1, wherein the voice control module generates the voice command information by recognizing spoken language indicating whether a power level should be incrementally increased or decreased.

### Claim 8 (depends on 1)

The system of claim 1, wherein the voice control module generates the voice command information by recognizing spoken language indicating whether a pulse duration should be incrementally increased or decreased.

### Claim 9

A method for delivering laser energy to an eye of a patient using an ophthalmic laser treatment system, the method comprising:
capturing audio data;
generating voice command information based on the captured audio data by recognizing spoken language indicating whether current values for parameters should be incrementally increased or decreased;
generating parameter information based on the voice command information; and
setting parameters for the delivered laser energy based on the parameter information.

### Claim 10 (depends on 9)

The method of claim 9, further comprising generating the voice command information by recognizing spoken language identifying the parameters for which the current values should be incrementally increased or decreased.

### Claim 11 (depends on 9)

The method of claim 9, further comprising capturing the audio data in response to detecting a predetermined wake word.

### Claim 12 (depends on 9)

The method of claim 9, further comprising providing audible feedback confirming the parameter information and/or the voice command information.

### Claim 13 (depends on 9)

The method of claim 9, wherein the laser energy is delivered to the eye of the patient by a body-mounted laser-indirect ophthalmoscope (LIO) system, a table-top LIO system, or a slit-lamp device.

### Claim 14 (depends on 9)

The method of claim 9, further comprising generating the parameter information based on the current values for the parameters and a predetermined safety policy.

### Claim 15 (depends on 9)

The method of claim 9, further comprising generating the voice command information by recognizing spoken language indicating whether a power level should be incrementally increased or decreased.

### Claim 16 (depends on 9)

The method of claim 9, further comprising generating the voice command information by recognizing spoken language indicating whether a pulse duration should be incrementally increased or decreased.

### Claim 17

A system for delivering laser energy to an eye of a patient, the system comprising:
a microphone for capturing audio data;
a voice control module for receiving the captured audio data and generating voice command information based on the captured audio data by recognizing spoken language indicating whether the system should be placed in a standby mode or placed in a treat mode; and
a control module for controlling the delivery of the laser energy based on the voice command information.

### Claim 18 (depends on 17)

The system of claim 17, wherein parameters for the laser energy can be adjusted and/or the laser energy can be delivered while the system is in the treat mode.

### Claim 19

A method for delivering laser energy to an eye of a patient using an ophthalmic laser treatment system, the method comprising:
capturing audio data;
generating voice command information based on the captured audio data by recognizing spoken language indicating whether the system should be placed in a standby mode or placed in a treat mode; and
controlling the delivery of the laser energy based on the voice command information.

### Claim 20 (depends on 19)

The method of claim 19, wherein parameters for the laser energy can be adjusted and/or the laser energy can be delivered while the system is in the treat mode.

### Claim 21 (depends on 1)

The system of claim 1, wherein incremental increase or decrease of the current values for the parameters is restricted to 20% or less of the current values.

### Claim 22 (depends on 1)

The system of claim 1, wherein one of the parameters is power of the delivered laser energy and the voice command information recognized by the voice control module includes one command to incrementally increase and another command to incrementally decrease the power.

### Claim 23 (depends on 1)

The system of claim 1, wherein one of the parameters is duration of the delivered laser energy and the voice command information recognized by the voice control module includes one command to incrementally increase and another command to incrementally decrease the duration.

### Claim 24 (depends on 1)

The system of claim 1, wherein one of the parameters is pulse duration of the delivered laser energy and the voice command information recognized by the voice control module includes one command to incrementally increase and another command to incrementally decrease the pulse duration.
