Definitions

  • the invention relates to a work station for the examination and treatment of the anterior segments of the eye and in particular for carrying out cataract operations according to the preamble of patent claim 1.
  • Cataract operations and in particular the insertion of lenses are usually carried out on a patient lying on an operating table or a couch.
  • the doctor uses an operating microscope both when removing the old lens and when inserting and "sewing in" the replacement lens.
  • the actual operation is not checked to determine whether the sewn-in lens has the correct effect.
  • the control of whether the sewn-in lens has the correct effect rather takes place only after the end of the surgical procedure at another ophthalmic workplace.
  • the known workplaces for the treatment of the anterior segments of the eye and in particular for performing cataract operations therefore exist diglich from an operating table or a couch for the patient and an operating microscope, which on a stand, a stand on the floor or a ceiling stand or the like. is held.
  • the invention has for its object to provide a workplace for the examination and treatment of the anterior eye sections and in particular for performing cataract surgery, which allows the attending physician to check during the operation whether the lens that he used instead of original eye lens that has the right optical effect.
  • the work station has a refraction measuring device which can be arranged in front of the eye to be examined or treated instead of the surgical microscope.
  • the attending doctor can thus bring the refraction measuring device briefly in front of the eye to be treated during the actual operation and so check whether the lens that he is replacing the original lens in the eye is suitable in terms of its optical effect that the patient can see clearly without a visual aid can.
  • the surgical microscope and the refraction measuring device can, for example, be attached to a displacement device which translates the two devices. However, it is particularly preferred if the surgical microscope can be pivoted about an axis or column in a manner known per se and the refraction measuring device is pivotably articulated on the same axis or column.
  • the column can be part of a floor stand or a ceiling stand.
  • the refraction measuring device can be attached to a conventional column, which is available for conventional surgical microscopes, as an additional element. It is possible to couple the surgical microscope and the refraction measuring device with one another in such a way that the refraction measuring device is brought exactly into the optical axis of the surgical microscope by a pivoting movement of the surgical microscope against a stop or the like. The operating microscope is then pivoted in front of the eye again in such a way that the eye can be observed.
  • any refraction measuring device can be used as the refraction measuring device.
  • an objective refraction measuring device in which it is not the patient but the treating doctor who decides whether the projected optotypes or the like are sharply imaged on the fundus.
  • Refraction measuring devices can be used, in which the doctor manually shifts an optometer lens or the like and determines the spherical refractive index and the astigmatism from the shift or rotation of a cylindrical lens.
  • autorefractor is particularly advantageous.
  • Commercially available devices can be used which, in particular, automatically determine the refractive index of the lens used, based on the focus of a measurement figure projected onto the fundus of the eye, and thus determine whether the lens used has a suitable effect.
  • the workplace according to the invention can be set up for the treatment of seated patients. However, it is particularly advantageous to design it such that the patient lies on an operating table or the like during treatment.
  • the refraction measuring device is provided with a deflection device which directs the beam path into the eye of the lying patient Redirects patient.
  • the deflection device is included Prisms or the like are preferably designed such that the values determined for the astigmatism axis also apply to the lying patient without conversion.
  • Fig. 1 shows an embodiment for a work station according to the invention.
  • Fig.l shows an embodiment for a workplace according to the invention for the examination and treatment of the anterior eye sections.
  • a column 1 is attached by means of a plate 2 on the floor, not shown.
  • On the column 1 there is a swivel joint 3, which carries two arms 31 and 32.
  • a surgical microscope 4 with a binocular view 41 for the doctor is attached to the arm 31.
  • a refraction measuring device 5 is attached to the arm 32, likewise with binocular insight for the doctor.
  • the refraction measuring device 5 can be any type of subjective or objective refraction measuring device, but it is particularly preferred if the refraction measuring device is an objective measuring device in which a measuring figure, such as a test mark is projected onto the back of the eye and the focusing of the test mark on the back of the eye is monitored by a sensor and / or by the doctor.
  • the test mark can in particular be designed such that it allows not only the determination of the so-called spherical ametropia, but also a possible eye astigmatism according to amount and axis position.
  • FIG. 1 Not shown in FIG. 1 is a couch or an operating table on which the patient lies and any other devices.
  • an examination and treatment of the anterior eye sections such as, for example, a cataract operation on a patient lying on the operating table or a couch, can be carried out as follows:
  • the attending doctor uses the surgical microscope 4 to carry out the examination and the operation on the eye.
  • the success of the operation is checked in that the doctor "swings away" the surgical microscope during the operation - for example after inserting and before sewing the lens.
  • the surgical microscope 4 and the refraction measuring device 5 are attached to the same pivot joint 3, the Refraction measuring device, in particular when stops (not shown) are provided, are transferred exactly to the location of the operating microscope 4, so that the orientation of the patient lying on the operating table or the couch with the optical axis of the operating microscope is maintained when the refraction measuring device 5 is used instead of the surgical microscope 4.
  • the adjustment of the devices held on the column 1 relative to the patient lying on the not shown couch or the operating table can be done in a known manner by a corresponding adjustment of the operating table and / or the column 1.
  • a commercially available refraction measuring device such as is usually used for refractioning a seated patient, can in particular be used as the refraction measuring device 5.
  • a deflection mirror 51 which is shown in broken lines in FIG. 1, into the beam path of the refraction measuring device 5. If necessary, measures must be taken to correct the measured values shown on the basis of the changed optical path length.

Abstract

L'invention concerne un poste de travail pour l'examen et le traitement des parties antérieures de l'oeil, qui peut notamment être utilisé pour réaliser des opérations de la cataracte sur des patients allongés sur une table d'opération, à l'aide d'un microscope d'opération. A la place dudit microscope d'opération, on peut placer un dispositif de mesure de la réfraction, devant l'oeil à examiner et/ou à traiter.
