<Overview>
The ophthalmic information processing apparatus exemplified in the present disclosure includes a control unit that controls various processes. The control unit acquires patient eye information. The patient eye information is information created before the surgery is performed, and is information in which a plurality of information including the medical device information to be inserted and the preoperative image information are associated with each other. The information on the medical device to be inserted is information for identifying the medical device to be inserted into the eye (for example, an intraocular lens) to be inserted into the patient's eye. The preoperative image information is the anterior segment image information of the patient's eye before the operation. In addition, the control unit acquires the image information at the time of surgery, which is the image information of the anterior segment of the patient's eye at the time of surgery. The control unit acquires the preparatory medical device information that identifies the intraocular insertion medical device prepared at the time of surgery. The control unit collates the preoperative image information with the surgical image information, and also collates the information on the medical device to be inserted with the information on the preparatory medical device to determine the suitability of the preparation for the surgery. Therefore, the ophthalmic information processing device can reduce the possibility that the patient's eye is mistaken, and also greatly reduce the possibility that an unscheduled intraocular insertion medical device is accidentally inserted into the patient's eye. Can be done.

An intraocular lens (IOL) having a predetermined refractive power can be mentioned as an example of an intraocular insertion medical device. Intraocular insertion medical devices are medical devices other than intraocular lenses (for example, medical devices having specific optical characteristics and inserted into the cornea, or medical devices inserted behind the corneal flap, etc.). It may be.

The control unit may collate the preoperative image information with the intraoperative image information by using at least a portion of the image outside the iris (for example, a blood vessel of the sclera or conjunctiva). Surgery to insert an intraocular insertion medical device into the patient's eye is often performed with mydriasis (widening the pupil). When mydriasis occurs, the iris is difficult to appear in the anterior segment image. However, by collating the images using at least the portion outside the iris, even mydriatic eyes can be collated appropriately.

However, it is also possible to change the collation method between the preoperative image information and the postoperative image information. For example, the image information may be collated by using at least the iris pattern in the vicinity of the outer peripheral portion of the iris. Further, the image information may be collated by using both the portion outside the iris and the iris pattern in the vicinity of the outer peripheral portion of the iris. In this case, the accuracy of collation is improved.

When the control unit determines that the preparation for surgery is inappropriate, the control unit may notify that the preparation is inappropriate. In this case, the surgeon can take appropriate measures such as changing the intraocular insertion medical device. Therefore, it is less likely that the patient's eye is mistakenly mistaken, or that an inappropriate intraocular insertion medical device is mistakenly inserted into the patient's eye. In addition, the control unit may prohibit subsequent surgery when it determines that the preparation for surgery is inappropriate.

The control unit obtains the identification information obtained by reading the identifier (for example, IC tag, QR code (registered trademark), bar code, etc.) provided with the intraocular insertion medical device with a reader, and prepares the medical device information. May be obtained as. In this case, the possibility that an inappropriate intraocular insertion medical device is inserted into the patient's eye is further reduced as compared with the case where the operator or an assistant manually inputs the preparatory medical device information. However, the control unit may acquire information on preparatory medical equipment by having an assistant or the like operate the operation unit. Even in this case, the possibility of error is reduced as compared with the case where the intraocular insertion medical device is not identified. The "identifier provided accompanying the intraocular insertion medical device" may be, for example, an identifier attached to the package of the intraocular insertion medical device. Further, when the intraocular insertion medical device is preset in the insertion device for inserting the intraocular insertion medical device into the eye, the insertion device may be given an identifier. The identifier may be directly attached to the intraocular insertion medical device.

In the anterior segment information, when the intraocular insertion medical device is inserted into both the left eye and the right eye of the same patient, the medical device information to be inserted and the preoperative image information are obtained for each of the left eye and the right eye. They may be associated separately. In this case, even when the intraocular insertion medical device is inserted into both the left eye and the right eye of the same patient, the possibility of mistaking the left and right eyes is reduced.

<Embodiment>
Hereinafter, one of the typical embodiments in the present disclosure will be described with reference to the drawings. In the present embodiment, a case where the surgical device 1 used for cataract surgery or the like also serves as an ophthalmic information processing device that processes information about the patient's eye is illustrated. That is, in the present embodiment, the control unit 10 of the surgical apparatus 1 processes the ophthalmic information acquired from an external device or the like to determine the suitability of the surgical preparation. However, a device other than the surgical device 1 may function as an ophthalmic information processing device (details will be described later).

The ophthalmic surgery system 100 illustrated in this embodiment will be described with reference to FIG. The ophthalmologic surgery system 100 of the present embodiment includes a surgical device 1. The surgical device 1 is used by the surgeon at least in performing cataract surgery on the patient's eye. As an example, the surgical apparatus 1 of the present embodiment has a function of crushing and emulsifying the crystalline lens nucleus of the patient's eye, a function of supplying a perfusate to the patient's eye and sucking a substance from the patient's eye, and an intraocular lens of the patient's eye. It has a function to automatically insert an intraocular lens (hereinafter, may be referred to as "IOL"). However, the function of the surgical apparatus 1 can be appropriately selected. For example, the surgical apparatus 1 may not have a function of automatically inserting an intraocular lens.

The surgical apparatus 1 includes a control unit 10 that controls the surgical apparatus 1. The control unit 10 includes a CPU 11, a RAM 12, a ROM 13, and a non-volatile memory 14. The CPU 11 is a controller that performs various controls. The RAM 12 temporarily stores various information. The ROM 13 stores a program executed by the CPU 11 and various initial values. The non-volatile memory 14 is a non-transient storage medium capable of retaining the stored contents even when the power supply is cut off. The ophthalmic information processing program for executing the preparation suitability determination process (see FIG. 3) described later may be stored in the non-volatile memory 14.

The control unit 10 includes a display unit 16, an operation unit 17, a handpiece drive unit 21, an automatic insertion drive unit 23, a pole drive motor 25, a foot switch 26, an identifier reader 27, a memory interface 28, and an external communication interface 29. It is connected via a bus.

The display unit 16 displays various images. The operation unit 17 receives input of various instructions by being operated by a user (for example, an operator, an assistant, etc.). The handpiece driving unit 21 drives the connected handpiece 22. As the handpiece 22, for example, at least one of an ultrasonic handpiece that crushes and emulsifies the crystalline lens nucleus by ultrasonic vibration, a handpiece for perfusion suction that supplies and sucks the perfusion solution, and the like can be used. The handpiece drive unit 21 may include, for example, at least one of a peristaltic pump (peristaltic pump), a Venturi pump, a valve, and the like. The automatic insertion drive unit 23 drives the connected IOL automatic insertion machine 24. Various powers (for example, motor power, air pressure, oil pressure, magnetic force, etc.) can be used as the power of the IOL automatic insertion machine 24. The pole drive motor 25 changes the pressure of the perfusate supplied to the patient's eye by moving the pole supporting the container of the perfusate up and down. The foot switch 26 is operated by the user's foot in order for the user to input various operation instructions and the like.

The identifier reader 27 reads an identifier (for example, an IC tag, a QR code (registered trademark), a barcode, etc.) provided attached to the intraocular lens. The identifier may be affixed to, for example, the package of the intraocular lens. Further, when the intraocular lens is preset in the intraocular lens insertion device (injector), the identifier may be attached to the intraocular lens insertion device. In the present embodiment, the identification information (prepared lens information) read by the identifier reader 27 is acquired by the control unit 10 as one of the ophthalmic information. The memory I / F 28 reads various information from the mounted removable memory (for example, USB memory, memory card, etc.) 31.

The external communication I / F29 controls communication with an external device (either wired communication or wireless communication). The surgical device 1 of the present embodiment can communicate with, for example, a surgical microscope 41, an axial length measuring device 42, a corneal shape measuring device 43, a personal computer (hereinafter referred to as “PC”) 44, and the like. The surgical microscope 41 photographs the patient's eye from the front during the operation, and shows the photographed image (anterior eye portion image) to the operator. The axial length measuring device 42 measures the condition of the patient's eye including the axial length of the patient's eye. The corneal shape measuring device 43 measures the condition of the patient's eye including the corneal shape of the patient's eye. The PC 44 can perform various types of information processing. The axial length measuring device 42 and the corneal shape measuring device 43 can also acquire an anterior segment image by photographing the patient's eye from the front.

The patient eye information used in the ophthalmologic surgery system 100 of the present embodiment will be described with reference to FIG. The patient eye information is information in which a plurality of information including the lens information to be inserted and the preoperative image information are associated with each one or a plurality of patient eyes. Patient eye information is created prior to surgery. As an example, the patient eye information in the present embodiment includes "patient name", "left and right eye information", "lens information to be inserted", "astigmatism axis direction", "corneal port position", and "preoperative image information". Is included.

The "patient name" may be substituted by a patient ID or the like that identifies the patient. Further, when the patient eye identification code information for identifying the patient eye is generated from the preoperative image by performing image processing on the preoperative image, the patient name, the patient ID, and the like may be omitted. "Left and right eye information" indicates whether the eye to be operated on is the patient's left eye or right eye. The “lens information to be inserted” is information for identifying an intraocular lens to be inserted into the patient's eye. As an example, in the present embodiment, the manufacturer name, product name, power, and the like of the lens to be inserted are used as the lens information to be inserted. However, the lens ID or the like for identifying the lens to be inserted may be used as the lens information to be inserted.

The "astigmatism axis direction" is information indicating an appropriate direction of the astigmatism axis when the intraocular lens is installed in the eye when the lens to be inserted is an intraocular lens for correcting astigmatism. The "corneal port position" is information indicating an appropriate position of an incision formed in the cornea when the intraocular lens is inserted into the eye. As an example, in this embodiment, the "astigmatic axis direction" and the "corneal port position" are indicated by angles. "Preoperative image information" is information on the anterior segment image of the patient's eye before surgery. In addition to the pupil and iris of the patient's eye, the anterior segment image in the present embodiment also includes portions located outside these (for example, sclera and conjunctiva). The "pre-surgery" may be, for example, an examination performed prior to the surgery to determine the intraocular lens to be inserted into the patient's eye. In this case, the preoperative image is taken by an ophthalmologic examination device (for example, at least one of an axial length measuring device 42, a corneal shape measuring device 43, and an ocular refractive power measuring device for measuring the refractive power of the eye). You may.

As illustrated in FIG. 2, in the present embodiment, when the intraocular lens is inserted into both the left eye and the right eye of the same patient (patient “A” in FIG. 2), it is scheduled to be inserted in the left eye. The lens information and the preoperative image information, and the lens information to be inserted in the right eye and the preoperative image information are associated separately. Therefore, even if the intraocular lens is inserted into both the left eye and the right eye of the same patient, the possibility of mistaking the left and right eyes is reduced.

In the present embodiment, at least one of the axial length measuring device 42 and the corneal shape measuring device 43 has a function of calculating the power of an intraocular lens suitable for the patient's eye by an intraocular lens power calculation formula. In addition, at least one of the axial length measuring device 42 and the corneal shape measuring device 43 has a function of photographing the anterior segment of the patient's eye before surgery. In the present embodiment, the patient eye information is created by at least one of the axial length measuring device 42 and the corneal shape measuring device 43, and then the surgical device 1 is controlled via the memory I / F28 or the external communication I / F29. Acquired by part 10. However, the device for creating the patient's eye information and the method for creating the patient's eye information can be appropriately changed. For example, the control unit 10 of the surgical device 1 may acquire the lens information to be inserted, the preoperative image information, the astigmatic axis direction, and the like from an external device, and create patient eye information using the acquired information. Further, the PC 10 acquires the measurement result of the patient's eye and the anterior segment image information by the axial length measuring device 42 and the corneal shape measuring device 43, and determines the intraocular lens to be inserted based on the acquired measurement result and the like. Patient eye information may be created.

The preparation suitability determination process executed by the ophthalmic information processing apparatus (as an example, the surgical apparatus 1) of the present embodiment will be described with reference to FIGS. 3 and 4. In the preparation suitability determination process, whether or not the preparation for surgery on the patient's eye is appropriate is determined based on the patient's eye information. The preparation suitability determination process is executed by the CPU 11 of the control unit 10 when the start instruction is given. The CPU 11 executes the preparation suitability determination process illustrated in FIG. 3 according to the ophthalmic information processing program stored in the non-volatile memory 14.

First, the CPU 11 acquires patient eye information (see FIG. 2) (S1). As mentioned above, the patient eye information may be created on any device. As an example, the CPU 11 of the present embodiment acquires patient eye information created by the axial length measuring device 42 or the corneal shape measuring device 43 by communication or a removable memory 31.

Next, the CPU 11 acquires image information at the time of surgery (S2). The surgical image information is information on the anterior segment image of the patient's eye at the time of surgery. That is, the image information at the time of surgery is the information of the image taken from the front of the patient's eye performing the surgery. The image information at the time of surgery may be, for example, information of an image of the patient's eye of a patient lying on an operating table in an operating room. Surgical images are taken at least after the intraocular lens to be inserted into the patient's eye is determined based on the test results. As an example, the control unit 10 of the surgical apparatus 1 of the present embodiment inputs the information of the anterior segment image at the time of surgery (more precisely, immediately before the surgery) taken by the surgical microscope 41 to the external communication I / F29 or the memory I. Obtained via / F28. However, the method by which the control unit 10 acquires image information during surgery can be appropriately changed. For example, the control unit 10 may acquire information on the anterior segment image taken by the camera included in the surgical apparatus 1 itself, or acquire information on the anterior segment image captured by a device other than the operating microscope 41. You may.

Next, the CPU 11 collates whether or not the surgical image acquired in S2 and the preoperative image included in the patient's eye information match (S4). As an example, in the present embodiment, the operator, an assistant, or the like operates the operation unit 17, and the patient name and the information of the left and right eyes of the patient who is going to perform the operation are specified in advance. The CPU 11 of the present embodiment collates the preoperative image associated with the specified patient name and left and right eye information with the surgical image acquired in S2, so that the patient's eye performing the operation can perform the operation. Determine if it is correct. However, the method of identifying the patient's eye undergoing surgery can be changed as appropriate. For example, the CPU 11 collates each of one or a plurality of preoperative images included in the patient's eye information with the preoperative image, and performs surgery on the patient's eye associated with the preoperative image matching the surgical image. It may be identified as the patient's eye being attempted. In this case, it is not necessary for the surgeon or assistant to identify the patient's eye by himself / herself. Therefore, the possibility of human error or the like is further reduced.

The method of collating the surgical image with the preoperative image can be appropriately selected. As an example, the CPU 11 of the present embodiment extracts a feature portion included in each of the images at the time of surgery and the image before surgery by performing well-known image processing. Next, the CPU 11 collates the extracted characteristic portions to determine whether or not the surgical image and the preoperative image are the same patient eye image.

The image collation method in the present embodiment will be described in detail with reference to FIG. As shown in FIG. 4, the preoperative image is often taken in a state where mydriasis (expanding the pupil 51) by a drug is not performed. On the other hand, surgical images are often taken with mydriasis in order to facilitate insertion of an intraocular lens. When mydriasis is performed, the area of the iris 52 of the patient's eye included in the image is reduced. Therefore, in the surgery of inserting an intraocular lens, unlike the case of corneal surgery using an excimer laser or the like, if two images are collated using only the pattern of the iris 52, the collation accuracy may decrease. ..

Therefore, in the present embodiment, the CPU 11 collates the preoperative image and the postoperative image by at least extracting and collating the characteristic portion of the image outside the iris 52 (for example, sclera or conjunctiva). To do. As a result, even the image of the patient's eye with mydriasis is appropriately collated. The characteristic portion that can be used for collation may be at least one of, for example, a blood vessel, a blood pool, a shape of an outer peripheral portion of the iris 52, and the like. It is also possible to use the iris pattern in the vicinity of the outer peripheral portion of the iris 52 for collation.

When the surgical image and the preoperative image do not match (S4: NO), the CPU 11 notifies at least one of the surgeon and the assistant that the preparation for the surgery is inappropriate (S11). The process returns to S1. In this case, the surgeon, the assistant, and the like can confirm in advance whether or not the preparation for the surgery is appropriate, and if the preparation is inappropriate, the preparation can be redone. Note that the notification in S11 may be appropriately performed by at least one method such as image, voice, and lighting of a lamp.

When the image at the time of surgery and the image before surgery match (S4: YES), the CPU 11 acquires the preparatory lens information (S5). The prepared lens information is information for identifying an intraocular lens prepared at the time of surgery (specifically, immediately before surgery). As described above, in the present embodiment, an identifier is provided in association with the intraocular lens. The CPU 11 acquires the intraocular lens identification information read by the identifier reader 27 (see FIG. 1) as the preparatory lens information. Therefore, the possibility of human error is reduced as compared with the case where the surgeon or an assistant manually inputs the prepared lens information. The CPU 11 may acquire the preparatory lens information read by another device (for example, PC44 or the like) via communication or the removable memory 31 or the like. Further, the preparation lens information may be input by the operator, the assistant, or the like operating the operation unit.

Next, the CPU 11 collates whether or not the prepared lens information and the lens information to be inserted match (S7). That is, the CPU 11 determines whether or not the lens to be inserted associated with the specified patient eye matches the lens prepared at the time of surgery. If they do not match (S7: NO), the CPU 11 notifies that the preparation for surgery is inappropriate (S11), and the process returns to S1.

When the prepared lens information and the lens information to be inserted match (S7: YES), the CPU 11 determines at least one of the "astigmatic axis direction" and the "corneal port position" associated with the specified patient eye. , Guide the surgeon (S8). For example, the CPU 11 may display at least one of the "astigmatism axis direction" and the "corneal port position" on the display unit 16. Next, the CPU 11 finishes the preparation suitability determination process in a state where the operation can be executed (S9).

The techniques disclosed in the above embodiments are merely examples. Therefore, it is possible to modify the techniques exemplified in the above embodiments. For example, in the above embodiment, the surgical device 1 used for cataract surgery or the like functions as an ophthalmic information processing device that executes a preparation suitability determination process (see FIG. 3). However, a device other than the surgical device 1 may function as an ophthalmic information processing device. For example, the operating microscope 41, the axial length measuring device 42, the corneal shape measuring device 43, or the PC 44 may function as an ophthalmic information processing device. Further, an ophthalmic laser surgical apparatus or the like that crushes the crystalline lens nucleus by condensing an ultrashort pulse laser in the crystalline lens may function as an ophthalmic information processing apparatus.

In addition, the specific processing method of the preparation suitability determination process can be changed as appropriate. For example, the determination of whether or not the lenses match (S7) may be performed before the determination of whether or not the images match (S4), or these determinations may be performed at the same time. Good.
