Description

FIELD OF THE DISCLOSURE The present disclosure relates generally to eye surgery systems, and particularly to user interfaces and algorithms to manage user defined phacoemulsification protocols. BACKGROUND OF THE DISCLOSURE A cataract is a clouding and hardening of the eye's natural lens, a structure which is positioned behind the cornea, iris and pupil. The lens is mostly made up of water and protein and as people age these proteins change and may begin to clump together obscuring portions of the lens. To correct this, a physician may recommend phacoemulsification cataract surgery. In the procedure, the surgeon makes a small incision in the sclera or cornea of the eye. Then a portion of the anterior surface of the lens capsule is removed to gain access to the cataract. The surgeon then uses a phacoemulsification probe, which has an ultrasonic handpiece with a needle. The tip of the needle vibrates at ultrasonic frequency to sculpt and emulsify the cataract while a pump aspirates particles and fluid from the eye through the tip. Aspirated fluids are replaced with irrigation of a balanced salt solution to maintain the anterior chamber of the eye. After removing the cataract with phacoemulsification, the softer outer lens cortex is removed with suction. An intraocular lens (IOL) is then introduced into the empty lens capsule restoring the patient's vision. The disclosure of US2014/114296A1 provides methods and systems for planning and forming incisions in a cornea, lens capsule, and/or crystalline lens nucleus. A method includes measuring spatial dispositions, relative to a laser surgery system, of at least portions of the corneal anterior and posterior surfaces. A spatial disposition of an incision of the cornea is generated based at least in part on the measured corneal anterior and posterior spatial dispositions and at least one corneal incision parameter. A composite image is displayed that includes an image representative of the measured corneal anterior and posterior surfaces and an image representing the corneal incision. The present disclosure will be more fully understood from the following detailed description of the examples thereof, taken together with the drawings in which: BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a pictorial view of a phacoemulsification system constructed to operate in accordance with an example of the present disclosure;Figs. 2A and 2B are schematic illustrations of a graphical user interface (GUI) of the system of Fig. 1, the GUI displaying two predefined user protocols, in accordance with an example of the present disclosure; andFig. 3 is a flow chart describing steps providing a physician with a predefined phacoemulsification protocol on a GUI and means to modify the protocol and verify protocol compatibility, in accordance with examples of the present disclosure. SUMMARY OF THE INVENTION The invention is defined in the independent claims. Further embodiments are defined in the dependent claims. Surgical methods disclosed herein, whilst not encompassed by the wording of the claims, are considered as useful for understanding the invention. DETAILED DESCRIPTION OF EXAMPLES OVERVIEW A phacoemulsification system typically includes a graphical user interface (GUI), presented on a suitable Input/Output (I/O) device such as on a touchscreen, to enable a user to define a phacoemulsification protocol and modify its parameters. It is customary for an eye surgeon, just before a procedure is conducted, to customize protocol parameters using, for example, multiple tabs of the GUI displayed on such a touchscreen. However, given that an eye surgery system may be used by many surgeons, such repeated customizations are time consuming and prone to errors. As an example of protocol customization, a phacoemulsification I/O may define needle vibration, including a number of possible different trajectories, e.g., longitudinal, planar (e.g., elliptical, circular), torsional, as well as in combinations and sub-combinations of such trajectories. In addition, the user may desire to use sequences of such trajectories. Another example of customization includes vibration driving waveform and power, and, as other examples, aspiration rate and vacuum level. Examples of the present disclosure that are described herein provide methods and apparatus that enable defining (e.g., generating) one or more eye surgery protocols on an eye surgery system and/or uploading one or more user defined eye surgery protocols to the eye surgery system, and compatibility testing of the defined (e.g., generated) and/or predefined protocols with the system, as well as testing compatibility among the parameters of each user protocol. The disclosed techniques retest such compatibilities subsequent to user modification of one or more parameters of a predefined protocol, e.g., after a protocol is uploaded to the system and/or GUI. The one or more user defined eye surgery protocols can be uploaded to an eye surgery system from a
