Invention embodiment
Ophthalmologic device for laser therapy comprises (Fig. 1) optical unit 1, it is with two lasing light emitters 2 (semiconductor laser), each lasing light emitter is furnished with optical forming device 3 (lens, be installed on the axis of this emitter), supply laser emission to act on the position (on Fig. 1, not marking) of a correspondence in calibration district (schematically illustrating).Optical unit 1 also includes location visual field limiter (for example, diaphragm) generation and watches passage 5, provides the direction of patient's sight line.Diaphragm 4 (3 millimeters in aperture) is positioned on the axis 6 of optical unit 1, and 25 millimeters apart from the ingate, the purposes of this unitary ingate 7 (duck eye or eyepiece) is to watch in therapeutic process for the patient.In order to shine the position at 3 o'clock of calibration district and 9 o'clock, generating laser 2 is arranged in the both sides of diaphragm 4, is symmetrical in the axis 6 of optical unit 1.The laser irradiation direction of at this moment watching passage and acting on eyes is conllinear not.
In addition, optical unit 1 can comprise to be used to shine the foveal region of retina district has the visible light lasing light emitter 8 (He-Ne laser instrument) of optical coupling with the passage 5 of watching unit 1.Realize coupling with half-mirror 9, reflecting mirror is installed in source 8 and watches on the axis of passage 5, constitutes suitable angle.The condition of choosing of the penetrating coefficient of reflecting mirror 9 is not hinder the patient to watch the target in a distant place by the outlet opening 10 of optical unit 1 with it.In order to make the patient watch laser spot figure, on the axis in source 8, diffuse scattering mechanism (clouded glass) can be installed between source and reflecting mirror 9 from source 8.
Device can be made into the monocular structure, also can be the binocular structure.Different with the monocular device that Fig. 1 shows, in the binocular device of Fig. 2, each eyepiece respectively has the laser emitting source 2 of a band optical forming device 3.In addition, source 8 is whole device service, by means of half-mirror 9, watches passage 5 that optical coupling is arranged for two of it and the first and second two optical units.Patient's eyes are through ingate 7, diaphragm 4, reflecting mirror 9, outlet 10 distant place targets of watching the visual field of being limited by passage 5 that is arranged in optical unit 1.Fig. 2 apparatus features is that to watch the light path of passage 5 are broken lines, has dislocation between the outlet 10 relative ingates 1 of optical unit 1.Two reflecting mirrors 12,13 that above characteristics rely on relative unit axis 6 to tilt realize that their mutually countershaft 6 directions are laterally placed, and one of them is towards the ingate 7, and another is towards outlet opening 10.
In the binocular acting device, the outlet opening 10 of optical unit 1 may have displacement each other, that is to say, the distance between them may be less than the interpupillary distance of patient's eye.Above measure makes and might reduce to the above-mentioned untoward reaction of patient minimum.
The binocular acting device can add adjustment mechanism in addition, and the optical unit of band visual field delimiter is housed thereon.Optical unit can move (as opera glass) each other at the horizontal direction perpendicular to their axis makes the distance of watching passage of two optical units consistent with patient's interpupillary distance.
On Fig. 3, adopt generating laser 2 as source 8 (referring to Fig. 1), for this reason it by diverter and with these unitary passage 5 optical coupled of watching, diverter also is in order to act on the foveal region of retina district.This radiation diverter is made of two half-mirrors 14 and 15, and one of them (14) towards the ingate 7 of optical unit 1, another is towards lasing light emitter 2.
Can be made into plate shape on diaphragm 4 structures, for example, stripe board with holes, the hole is positioned on the above-mentioned axle of optical unit, in its one or both sides (be fixed on the cell enclosure, diaphragm is as the same) one or two lasing light emitter (for example laser diode) is installed, each emitter all is with an optical forming device.If the use circular iris can shine the position by the quilt that arrives eye in order to make the radiation from lasing light emitter, (in case of necessity) opens via hole on it.Diaphragm 4 can be installed on the shell of unit 1, can move (in order to provide the channel direction of watching of demand) and be fixed on selected position on the plane of diaphragm.Certainly may be with other scheme limits vision, for example with lens or the telescopic system be made up of mirror, corresponding its amplification patient's visual field reduces.Adopt this visual field limiter scheme, the inlet of optical unit is on the axis of visual field limiter system, and the axis of visual field limiter system is the axis of optical unit just.The aperture of telescopic system, its determining positions in the unit guarantee that in the visual field visual field is the 3-6 degree.
Can exceed above-mentioned field-of-view angle scope.Lower limit is not require great effort especially the minimum angles patient to differentiate object.The upper limit is that pupil is moving within sweep of the eye, and the ray of lasing light emitter can not got to pupil.
Can see visual field limiter importantly being arranged from above discussion, and not lie in its specific embodiments for this invention.In order to affact amphiblestroid center, implement to watch the scheme of passage to have multiple.Each optical unit 1 of the first has an infrared ray or visible radiation source (for example laser) 8, and with this unitary passage of watching optical coupling is arranged.Another program is to carry out optical coupling for the passage (the monocular instrumnent device is, and the binocular device is two) of watching that whole device adds one or several such source and they and all optical unit.As such source, can in each optical unit, utilize among the generating laser, interpolation is with this unitary optical coupling of watching passage, send a part of radiant light to the foveal region of retina part through the overshoot diverter, the radiant intensity of telling should be than low 3 magnitudes of generating laser radiant intensity.Therefore, the radiation diverter can be made up of two coupled thin glass of plane parallel optics or piezoid.One of them inclination is installed on the Laser emission body axis, and another is installed on the axis of optical unit in a similar fashion.Replace above-mentioned thin slice and also can use translucent optical coupling reflecting mirror (the same magnitude of penetrating coefficient), one of them is towards the inlet of optical unit, and another is towards generating laser.Such diverter does not hinder device to finish the basic function of oneself-with watching the passage patient sight line to be remained on laser stimulation ciliary muscle under the condition of desired direction.
The schematic diagram shows of describing source and the optical coupling of watching passage.For above-mentioned invention embodiment important only be to exist optical coupling to guarantee that laser emission acts on the calibration district that the foveal region of retina district acts on eye simultaneously, rather than concrete form of implementation.
Utilize the visible light lasing light emitter fascinating especially,, realize the optical coupling of watching passage of radiation and optical unit by means of generating in order or the device of interference image at random as the above-mentioned source that acts on the foveal region of retina district.Can utilize for example suitable diffraction grating or diffuse scattering device (for example clouded glass) as such device.The laser spot point diagram that the medium diffuse scattering generates under latter event itself is the object of watching for the patient.The state of interferogram clearly that at this moment generates on retina and eyes optics organ and condition of illness are irrelevant.The patient accepts the organ of adjusting of so visual eyes can be nervous, loosens fully.In order to watch laser irradiation speckle figure in therapeutic process, above-mentioned scattering mechanism can be placed on the source and as the source with watch between the tilting mirror of passage optical coupling.Should emphasize once more, watch the observed speckle figure of passage can play immobilized patients sight line object.Other device design also is feasible, and independently unit is made in the additional laser source that acts on the foveal region of retina district, and it watches the optical coupling of passage to realize by means of the diffuser screen that is arranged in the patient visual field of additional introducing device with optical unit.
Device is running in the following manner.The suggestion patient 7 watches the distant place object (not shown on Fig. 1) that is positioned at outlet opening 10 back from the ingate, the speckle figure that perhaps watches diffuse scattering mechanism 11 to generate.At this moment the so fixing sight line of patient: make and watch object or speckle to be positioned at center, the visual field.After this, connect generating laser 2.With watching passage 5, the direction of patient's sight line that shaping diaphragm 4 is given, two positions at 3 o'clock of calibration district and 9 o'clock 4, about 14 millimeters apart from the center of speckles are delivered in the radiation of the emitter 2 that is shaped through optical forming device 3 simultaneously.The duration of a laser therapy, was generally 2 to 5 minutes by timer given (not shown on Fig. 1) as the way of [1].The treatment retina also inserts source 8 when needing, its radiation with reflecting mirror 9 along watching passage 5 to pass 7 directive foveal region of retina districts, ingate.The work (not shown on Fig. 1) in independent timer control source 8.After the scheduled time had arrived, timer was turned off generating laser 2 and source 8.The work of several timers is independently of one another.The frame mode of Fig. 3 is preferably adopted in their work synchronously if desired, and 8 effect simultaneously originates from source 2 here.With the work of timer by power supply and control device (not shown on Fig. 1) control source 2 and source 8 is not characteristics of the present invention, so it is not limited.Can utilize suitable shutter (for example electric light formula) to cut off the conveying of radiation to eyes calibration district and foveal region of retina district at emitter 2 and source 8 outputs place.When using binocular constructional device (Fig. 2), the working method of opticator is similar.Difference is before every treatment, watches the position of passage to put and own interpupillary distance consistent location for handle, and the patient need move the opticator 1 that links together with diaphragm 4 with the horizontal direction of adjustment mechanism (not shown on Fig. 2) mutually countershaft 6.Whether the patient is integrated according to two observed targets of eyes makes a decision.At this moment the optic axis 6 of watching axle and unit 1 of eyes should overlap fully.After this, above-described synergism can be realized simultaneously at patient's eyes.
In order to confirm to invent the probability of realization and the high efficiency that provides the laser therapy eye to adjust organ lesion, enumerate the example that uses apparatus of the present invention.
Patient K diagnoses 10 years progressivity myopia.Do not have the binocular vision 0.1 of correction, astigmatism-2.5Dptr is 0.9.Adjusting reserves relatively is-2.0Dptr.Patient carries out 10 days one courses of treatment of laser therapy.Act on 3 o'clock of calibration district and 9 o'clock place with 1.3 micron wave length iraser radiation monocular instrumnents.Accumulated dose 0.2J/cm
2Shine the calibration district and observe the combination of LASER SPECKLE structure by the passage of watching that collimates out with diaphragm simultaneously.
