Description

Laser Ophthalmology Equipment

The present invention relates to a laser ophthalmology device.

In the structure of the eye, about two-thirds of the refractive power is determined by the curvature of the anterior surface of the cornea, therefore, the refractive error of the eye can be significantly improved or eliminated by changing the shape of the cornea. The cornea is a multi-layered constructed film, the anterior and posterior surfaces of which are nearly concentric, and have a central thickness of about 0.5 to 0.6 millimeters, and a peripheral thickness of about 0.6 to 0.8 millimeters. The multi-layered structure of the cornea consists of Epithelium, Bowman, Stroma, Descemet, and Endothelium in order from the anterior surface to the posterior surface. The central thickness of the epithelial cell layer is about 70 μm, and the thickness of the proelastic layer is about 12 μm. The thickness of the stromal layer accounts for about 90% of the total thickness of the cornea (about 500 μm), and is mainly composed of regularly arranged collagen fibers and interconnected corneal cells. The endothelial cell layer consists of a layer of hexagonal flat cells.

Based on the corneal architecture described above, since the stromal layer of the cornea has sufficient thickness, for corrective purposes, the anterior portion of the stromal layer can be resected to change its contour, thereby changing the power of the eye, while preserving most of the stromal tissue.

Various lasers are widely used in ophthalmic surgery, such as glaucoma, cataract, refractive surgery, etc. For example, ultraviolet (UV) lasers are used in refractive surgery (or corneal reshaping), where examples of UV lasers include 193 nm excimer lasers, fifth harmonic (213 nm) neodymium lasers Various lasers (Neodymium-Yttrium Aluminum Garnet; Nd-YAG laser), etc. Specifically, these UV Light lasers are widely used in laser refractive keratectomy (PRK) and laser in situ lamellar orthokeratology (LASIK). The effect of changing the diopter of the eye (correcting vision).

The laser ophthalmic devices currently on the market for performing LASIK all have a similar design, in which the optical axis of the patient's eye is aligned with the laser beam by moving the patient's operating table. Specifically, the patient will lie on an operating table that is precisely movable along the XYZ axes, by which the patient (ie, the surface of his cornea) is moved until the surface of the cornea reaches the surface of the laser ophthalmology device. the focus point of the microscope, and then set the laser beam transmission path. In the laser ophthalmology equipment, because the main cabinet with the laser light source is quite bulky and inconvenient to move, the laser beam is usually transmitted through the optical system, so that the laser beam is turned under the microscope after passing through the optical system. Downward orientation to align the optical axis of the microscope. During the use of this laser ophthalmic equipment, in order to align the visual axis of the patient's eyes with the laser beam, it is necessary to constantly move the operating table where the patient is located. It is inconvenient for operators (eg, doctors or surgical assistants) to use and lacks operational flexibility.

In addition, in the conventional laser ophthalmic equipment, as shown in Fig. 5B, when the laser beams L1'~L3' are incident on the patient's eye E, due to the large difference in the incident angle between the middle and the surrounding positions, it must be given Corresponding optical compensation avoids adverse effects on laser eye surgery due to excessive incident angle differences.

The purpose of the present invention is to provide a laser ophthalmic device with both convenience in use and flexibility in operation. Specifically, compared with the traditional laser ophthalmology device which achieves alignment between the two by moving the patient, the laser ophthalmology device provided by the present invention achieves the alignment between the two by moving the laser ophthalmology device separately. The components of the device are placed in separate cabinets and the laser scanning applicator therein is moved relative to the patient's eye to achieve alignment between the two, in which case there is no need to move the bulky procedure Instead of moving the patient table (that is, moving the patient), but only moving the laser scanning applicator disposed in one of the cabinets relative to the patient, the laser ophthalmic device of the present invention can simultaneously provide operation during laser eye surgery. User convenience and improved operational flexibility. In addition, the laser ophthalmic device provided by the present invention can convert the laser beam into a substantially parallel laser beam before the laser beam enters the patient's eyes, without additional optical compensation for laser beams with different incident angles. This can avoid adverse effects on the performance of laser eye surgery.

The laser ophthalmic equipment provided according to the present invention includes a first cabinet; a second cabinet provided separately from the first cabinet; a laser light source, which is arranged in the first cabinet and configured to generate a laser beam; a positioning device, disposed on the second cabinet and configured to locate the position of the patient's eye; a laser scanning applicator disposed on the second cabinet and configured to be moved to align the patient's eye based on the positioning result of the positioning device; actuated The device is arranged in the second cabinet and is configured to drive the positioning device and the laser scanning application device respectively to move along the X direction, the Y direction and the Z direction; the light guiding device is arranged between the laser light source and the laser scanning device between the applicators and configured to direct a laser beam generated by the laser light source toward the laser scanning applicator; and a controller disposed in the first cabinet and configured to electrically connect and control the laser light source, drive A device, and a laser scanning applicator, wherein the laser scanning applicator is configured to convert a laser beam from a light directing device into a substantially parallel laser beam and apply the substantially parallel laser beam to a patient's eye.

With the above-mentioned laser ophthalmic device of the present invention, since the alignment between the laser ophthalmic device and the patient's eye is achieved only by moving the laser scanning applicator disposed in the second cabinet, it does not need to be relative to the laser The ophthalmic device moves the patient's position (that is, does not need to move the patient In the process of operating the laser ophthalmic equipment for laser ophthalmic surgery, the laser ophthalmic equipment according to the present invention is more convenient to use, and can more flexibly move the laser scanning applicator to the opposite The exact position of the patient's eye to facilitate laser eye surgery with greater precision.

The movement of the positioning device 5 and the laser scanning applicator 6 will be described in detail in the following description, and will not be repeated here.

The controller 9 is configured to electrically connect and control various components of the laser ophthalmic apparatus 1 . In the laser ophthalmic apparatus 1 according to the present invention, the controller 9 electrically connects and controls the laser light source 4 , the driving device 7 , and the laser scanning applicator 6 .

In the embodiment according to the present invention, as shown in the first and second figures, the user interface 100 includes a screen and a keyboard for the operator to input relevant information required for performing laser eye surgery into the controller 9 In the storage device, the operation of the laser ophthalmic apparatus 1 is monitored, for example, the coarse positioning and the fine positioning of the laser scanning applicator 6 and the like. In addition, as shown in the second figure, the switch 200 is preferably a foot switch, which can issue a command under the operation of the user to make the laser light source 4 emit the laser beam L through the controller 9 . However, those skilled in the art should understand that the present invention is not limited to the above-mentioned types of user interfaces 100 and switches 200, and other types of user interfaces 100 and switches 200 can also be used as long as the above-mentioned functions can be achieved That's it.

Next, the process of operating the laser ophthalmology apparatus 1 according to the embodiment of the present invention to perform laser eye surgery will be described.

First, after the patient has been lying on the operating table 300 (ie, after the patient's eyes E have been in a fixed position), according to the predetermined position information pre-stored in the controller 9, the operator (eg, a doctor or a surgical assistant) The driving device 7 can be controlled by the controller 9 through the user interface 100, so that the driving device 7 drives the positioning device 5 to move it to a predetermined position. After the positioning device 5 is moved to this predetermined position, an operator (eg, a doctor or surgical assistant) can then position the patient's eye E by means of the positioning device 5 (ie, microscope and positioning beam).

Next, after the positioning device 5 has completed positioning the patient's eye E, similar to the driving device 7 driving the positioning device 5 , the driving device 7 will drive the laser scanning applicator according to the predetermined position information pre-stored in the controller 9 . 6 Move it to a predetermined position above the patient's eye E (this positioning may also be referred to as a coarse positioning). In addition to being driven according to the predetermined position information pre-stored in the controller 9, the laser scanning applicator 6 can be further moved to a more precise position with the patient's eye E according to the positioning result of the positioning device 5 on the patient's eye E. Aligned position (this positioning can also be called fine-tuned positioning). In detail, this fine adjustment position can be manually operated by the operator to the fine adjustment device (eg, the joystick 400 shown in the first and second figures) to control the driving device 7 to drive the laser scanning applicator 6 to move it to achieve.

It should be noted that, in the process that the laser scanning applicator 6 is moved to be aligned with the patient's eye E based on the positioning result of the positioning device 5, the positioning device 5 will continue to locate the position of the patient's eye E, thereby The position of the laser scanning applicator 6 is continuously adjusted to maintain the positioning accuracy.

After the laser scanning applicator 6 completes the above-mentioned coarse adjustment positioning and fine adjustment positioning, the user can operate the switch 200 to issue a command, and the command is transmitted to the laser light source 4 through the controller 9, so that the laser light source 4 emits corresponding The laser beam L is transmitted to the laser scanning applicator 6 through the light guide module 80 and the light guide arm 81 . At this time, the controller 9 controls the controller 9 according to the preset information stored in the controller 9 The laser scanning applicator 6 applies a laser beam L to the patient's eye E for laser eye surgery.

However, although the laser scanning applicator 6 has achieved alignment with the patient's eye E on the operating table 300 after the above-mentioned coarse and fine positioning, during laser eye surgery, due to the patient's eye E will still be rotated intentionally or unintentionally, so that its position deviates from the position when positioned by the positioning device 5, in this case, if the laser beam L applied to the patient's eye is not adjusted with the deviation of the position of the eye E The position of E may be distorted during laser eye surgery.

Therefore, in the laser ophthalmic apparatus 1 according to the present invention, the laser scanning applicator 6 preferably further comprises an eye tracking system 60 and a scanner 62 (see the third figure), and the eye tracking system 60 can be instantly and continuously reapplied The position of the patient's eye E (eg, the pupil) is located (tracked), and the scanner 62 can continuously fine-tune its center position according to the repositioning results of the eye tracking system 60 so that the laser scans the laser beam applied by the applicator 6 L enables more precise alignment of the patient's eye E.

Specifically, after the laser scanning applicator 6 has been moved to be aimed at the patient's eye E, the laser scanning applicator 6 is in the process of applying the laser beam L to the patient's eye E, the laser scanning applicator 6 The eye tracking system 60 relocates (tracks) the position of the patient's eye E (eg, the pupil) instantly and continuously under the control of the controller 9, and, according to the relocation result of the eye tracking system 60, the controller 9 controls The scanner 62 of the laser scanning applicator 6 makes it continuously fine-tune its center position to compensate for shifts in the position of the eye E caused by intentional or unintentional movement of the patient's eye E, so that the laser scanning applicator 6 applies The laser beam L of the is more precisely and instantly aimed at the patient's eye E, and the laser beam L is used to precisely perform laser eye surgery, such as LASIK surgery, on the patient's eye E (eg, cornea). In this way, during the laser eye surgery, it can be ensured that the distortion of the laser ablated cornea will not occur due to the deviation of the position of the patient's eye E.

Next, the travel path of the laser beam L when passing through the laser scanning applicator 6 will be described with reference to the fourth figure.

As shown in FIG. 4 , the laser scanning applicator 6 according to the present invention preferably further includes a lens 63 and a reflector 64 , wherein the lens 63 is arranged between the scanner 62 and the light guide arm 81 during the laser scanning at the distal side of the applicator 6 furthest away from the patient's eye E, and configured so that the laser beam L from the light guide arm 81 of the light guide 8 (third figure) is then passed through the scanner 62 and mirror 64 and converted into roughly parallel thunder beams (see laser beams L1-L3 in Figure 5A), the substantially parallel laser beams L1-L3 are then applied towards the eye E of the patient.

As shown in Fig. 5A and Fig. 5B, the laser beam L is not converted into a substantially parallel laser beam compared to the conventional laser ophthalmic equipment (see the laser beam L1'~ L3'), while the laser beams L1' to L3' incident on the patient's eye E at different incident angles (especially for the laser beam L1 with the largest difference in the incident angle between the middle and surrounding positions of the patient's eye E) are required. '~L3') to give corresponding optical compensation, so that the optical characteristics of the laser beams L1'~L3' incident on the patient's eye E at different incident angles should not be too different from each other, so as to avoid too large differences. The laser ophthalmology device of the present invention converts the laser beam L into substantially parallel laser beams L1-L3 and applies the substantially parallel laser beam L1 to the patient's eye E, which may adversely affect the performance of the ophthalmic surgery. ~L3 (see Fig. 5A), will effectively avoid the adverse effects on laser eye surgery caused by the difference between the laser beams L1'~L3' incident on the patient's eye E at different incident angles.

As shown in the first to third figures, in addition, in the laser ophthalmic apparatus 1 of the present invention, since the laser scanning applicator 6 can be independently driven to move to a desired position relative to the patient's eye E, Compared to conventionally moving the laser ophthalmic device almost entirely relative to the patient's eye E, the laser scanning applicator 6 of the present invention can be manipulated more flexibly or moved to a position closer to the patient's eye E, For example, the laser scanning applicator 6 of the present invention can preferably be moved to a position about three centimeters away from the eye E of the patient. In such a case, since the distance between the patient's eye E and the laser scanning applicator 6 applying the laser beam L is relatively short, the laser beam L applied by the laser scanning applicator 6 can be greatly reduced in reaching the The previous interference to the patient's eye E improves the precision of laser eye surgery.

To sum up, in the laser ophthalmic apparatus 1 of the present invention, since the laser beam L applied to the patient's eye E is substantially parallel laser beams L1 to L3 converted by the laser scanning applicator 6 (see See Fig. 5 A), the laser ophthalmic device of the present invention can effectively avoid the laser beams L1'˜L3' (see Fig. 5 B) that are incident on the patient's eyes due to the difference between the different incident angles. It is not necessary to give additional optical compensation, so the advantageous technical effect of improving the use efficiency of the laser ophthalmic device 1 can be achieved.

Furthermore, in the laser ophthalmic apparatus 1 of the present invention, since the laser scanning applicator 6 applying the laser beam L to the patient's eye E can be independently driven to move relative to the patient's eye E, it can be moved to At a position closer to the patient's eye E, the laser ophthalmic device 1 of the present invention can greatly reduce the interference of the laser beam L applied by the laser scanning applicator 6 before reaching the patient's eye E, so that the It can achieve a favorable technical effect of improving the accuracy of laser eye surgery.

Finally, in the laser ophthalmic apparatus 1 of the present invention, since the alignment between the laser ophthalmic apparatus 1 (the laser scanning applicator 6 ) and the patient's eye E is performed by moving the laser scanning applicator 6 , instead of moving the patient relative to the laser ophthalmic device, the operator (ie, the doctor or the surgical assistant) only needs to use the driving device 7 to make the laser in the process of operating the laser ophthalmic device 1 for laser eye surgery The scanning applicator 6 is moved to the position aligned with the patient's eye E, without the need to repeatedly move the relatively bulky operating table 300 where the patient is located. precision laser eye surgery.
