## Abstract

The present disclosure provides a system and method for managing patient data during ophthalmic surgery. The systems and methods include an ophthalmic surgical device operable to receive data from a RFID chip. Data from the RFID chip is transmitted to a RFID read-write module operably coupled to the ophthalmic surgical system. A processor identifies the RFID chip based on the received data and determines whether the data stored to the RFID chip varies from data received from a surgical microscope by more than a predetermined percentage. The processor can generate a warning when the data stored to the RFID chip varies from data received from a surgical microscope by more than a predetermined percentage.

## Claims

### Claim 1

An ophthalmic surgical device comprising:
a surgical microscope;
a user interface;
an RFID read-write module operable read an RFID chip and write patient data to an RFID chip associated with a patient;
surgical instrumentation;
a warning system; and
a processor operable to:
receive data from the RFID chip associated with a patient, the data from the RFID chip comprising a first measurement of an eye;
receive data from the surgical microscope associated with the patient, the data from the surgical microscope comprising a second measurement of the eye;
compare the data from the RFID chip to the data from the surgical microscope;
determine whether the eye has changed by determining whether the data from the RFID chip varies from the data from the surgical microscope by more than a predetermined percentage;
generate a warning, if the data from the RFID chip and the data from the surgical microscope vary by more than the predetermined percentage; and
transmit the warning to the warning system, causing the warning system to present a warning.

### Claim 2 (depends on 1)

The ophthalmic surgical device of claim 1, further comprising:
an RFID chip associated with the ophthalmic surgical system.

### Claim 3 (depends on 1)

The ophthalmic surgical device of claim 1, further comprising:
a control device associated with the ophthalmic surgical system, wherein the RFID chip is connected to the ophthalmic surgical device, the RFID chip operable to transmit data to the processor, and wherein the processor is further configured to generate and transmit a control signal to a control device, the control signal operable to pause the surgical instrumentation, when a warning is generated.

### Claim 4 (depends on 1)

The ophthalmic surgical device of claim 1, further comprising:
a control device associated with the ophthalmic surgical system, wherein:
the RFID chip is connected to the ophthalmic surgical device, the RFID chip operable to transmit data to the processor; and
the processor is further configured to generate and transmit a control signal to a control device, the control signal operable to render the ophthalmic surgical system inoperable of continuing a surgical operation, when a warning is generated.

### Claim 5 (depends on 3)

The ophthalmic surgical device of claim 3, wherein the processor is further configured to require receipt of a manual confirmation input before permitting a user to continue a surgical operation when a warning is generated.

### Claim 6 (depends on 4)

The ophthalmic surgical device of claim 4, wherein the processor is further configured to require receipt of a manual confirmation input before permitting a user to continue a surgical operation when a warning is generated.

### Claim 7 (depends on 3)

The ophthalmic surgical device of claim 3, wherein the device for manual confirmation of an adjustment is selected from at least one of: a button, a switch, a key, and a joystick.

### Claim 8 (depends on 4)

The ophthalmic surgical device of claim 4, wherein the device for manual confirmation of an adjustment is selected from at least one of: a button, a switch, a key, and a joystick.

### Claim 9 (depends on 1)

The ophthalmic surgical device of claim 1, wherein:
the warning system comprises a display operable to present a pictorial representation; and
the processor is further configured to generate the pictorial representation to indicate the warning generated, when a warning is generated.

### Claim 10 (depends on 1)

The ophthalmic surgical device of claim 1, wherein the warning system comprises at least one of: a speaker, a light indicator, and a haptic feedback device, to indicate that a warning was generated.

### Claim 11 (depends on 1)

The ophthalmic surgical device of claim 1, wherein the data from the RFID chip includes a first image of the eye of the patient.

### Claim 12 (depends on 11)

The ophthalmic surgical device of claim 11, wherein:
the data from the surgical microscope includes a second image of the eye of the patient, the second image being acquired using the surgical microscope; and
the processor operable to compare the data from the RFID chip to the data from the surgical microscope further comprises the processor operable to compare the first image to the second image.

### Claim 13

A method for performing ophthalmic surgery, comprising:
receiving first data representing a patient eye from an RFID chip associated with the patient, the data from the RFID chip comprising a first measurement of the eye;
receiving second data representing the patient eye from a surgical microscope, the data from the surgical microscope comprising a second measurement of the eye;
comparing the first data and the second data;
determining whether the eye has changed by determining whether the first data varies from the second data by more than a predetermined percentage;
generating a warning, if the first data and the second data vary by more than the predetermined percentage; and
transmitting the warning to a warning system, causing the warning system to present a warning.

### Claim 14 (depends on 13)

The method of claim 13, further comprising:
pausing the surgical instrumentation, when a warning is generated.

### Claim 15 (depends on 13)

The method of claim 13, further comprising:
rendering the ophthalmic surgical system inoperable of continuing a surgical operation, when a warning is generated.

### Claim 16 (depends on 14)

The method of claim 14, further comprising:
requiring receipt of a manual confirmation input before permitting a user to continue a surgical operation, when a warning is generated.

### Claim 17 (depends on 15)

The method of claim 15, further comprising:
requiring receipt of a manual confirmation input before permitting a user to continue a surgical operation, when a warning is generated.

### Claim 18 (depends on 13)

The method of claim 13, wherein the first data includes a first image of the patient eye.

### Claim 19 (depends on 18)

The method of claim 18, wherein the second data includes a second image of the patient eye, and wherein comparing the first data and the second data includes comparing the first image and the second image.
