Robot manipulator for eye surgery tool

1. An eye surgery apparatus, comprising:

an eye surgery tool having a distal end for insertion into an eye of a patient through an incision in the eye;

an imaging system, which is configured to acquire images showing the incision and at least part of the eye surgery tool;

a robotic arm coupled with the eye surgery tool, which is configured to move the distal end of the eye surgery tool inside the eye according to one or more commands issued during an eye surgery; and

a processor, which is configured to, during the eye surgery:

receive the images from the imaging system;

monitor the commands issued to the robotic arm;

detect, by analyzing the images, that a monitored command is expected to enlarge the incision; and

initiate a responsive action with respect to the detected command.

2. The eye surgery apparatus according to claim 1 , wherein the one or more commands are issued by one of a surgeon and an algorithm that the robotic arm executes.

3. The eye surgery apparatus according to claim 1 , wherein the processor is configured to identify a position of the at least part of the eye surgery tool, relative to the incision, by analyzing the images, and to detect, based on the identified position, that the command is expected to enlarge the incision.

4. The eye surgery apparatus according to claim 1 , wherein the processor is configured to block the detected command from being executed by the robotic arm.

5. The eye surgery apparatus according to claim 1 , wherein the processor is configured to output an alert to a surgeon with respect to the detected command.

6. The eye surgery apparatus according to claim 1 , wherein the eye surgery is a phacoemulsification procedure, the eye surgery tool is a phacoemulsification probe, and the imaging system is configured to image a tip of the phacoemulsification probe.

7. The eye surgery apparatus according to claim 1 , wherein the imaging system comprises a video camera, and wherein the images comprise video images.

8. An eye surgery method, comprising:

inserting a distal end of an eye surgery tool into an eye of a patient through an incision in the eye;

using an imaging system, acquiring images showing the incision and at least part of the eye surgery tool;

using a robotic arm, moving the distal end of the eye surgery tool inside the eye according to one or more commands issued to the robotic arm;

receiving the images from the imaging system;

monitoring the commands issued to the robotic arm;

detecting, by analyzing the images, that a monitored command is expected to enlarge the incision; and

initiating a responsive action with respect to the detected command.

9. The eye surgery method according to claim 8 , wherein the one or more of commands are issued by one of a surgeon and an algorithm that the robotic arm executes.

10. The eye surgery method according to claim 8 , wherein detecting that the monitored command is expected to enlarge the incision comprises identifying a position of the at least part of the eye surgery tool, relative to the incision, by analyzing the images, and detecting, based on the identified positions, that the command is expected to enlarge the incision.

11. The eye surgery method according to claim 8 , wherein initiating the responsive action comprises blocking the detected command from being executed by the robotic arm.

12. The eye surgery method according to claim 8 , wherein initiating the responsive action comprises outputting an alert to the surgeon with respect to the detected command.

13. The eye surgery method according to claim 8 , wherein the eye surgery is a phacoemulsification procedure, the eye surgery tool is a phacoemulsification probe, and the imaging system is configured to image a tip of the phacoemulsification probe.

14. The eye surgery method according to claim 8 , wherein the imaging system comprises a video camera, and wherein the images comprise video images.
