Embodiment Construction

[0024] Such as figure 1 As shown, the embodiment of the present invention provides a full femtosecond laser system for eyeball spin correction, which includes an anterior segment biometric unit, a spin control unit, a patient posture adjustment unit, a horizontal axis position marking unit, a negative pressure suction unit and a femtosecond laser system. second laser unit,

[0025] The anterior segment biometric unit collects eyeball position information when the patient is sitting, and sends the collected eyeball position information to the spin control unit. The eyeball position information includes eyeball pupil, iris, corneoscleral limbus and bulbar conjunctival vascular network image information;

[0026] The spin control unit collects the eyeball position information of the patient in the supine position, compares the eyeball position information in the supine position with the eyeball position information in the sitting position, obtains the eyeball spin information an...

Abstract

The invention discloses a full femtosecond laser system for eyeball spin correction. The full femtosecond laser system for eyeball spin correction comprises an eye anterior segment biological measurement unit, a spin control unit, a patient posture adjusting unit, a horizontal axial position marking unit, a negative pressure suction unit and a femtosecond laser unit, wherein the eye anterior segment biological measurement unit is used for collecting eyeball position information when a patient sits and sending the eyeball position information to the spin control unit; the spin control unit is used for collecting the eyeball position information of the patient in the supine position, comparing the eyeball position information of the patient in the supine position with the eyeball position information of the patient in the sitting position so as to obtain the eyeball spin information, and sending the eyeball spin information to the patient posture adjusting unit; the patient posture adjusting unit is used for adjusting the posture of the patient in the supine position according to the eyeball spin information, so that an absolute value of an eyeball spin angle is smaller than 1 degree; the horizontal axial position marking unit is used for completing horizontal axis marking of an operative eye in the sitting position according to a horizontal projection line; the negative pressuresuction unit is used for carrying out negative pressure suction and adjustment on the eyeball, so that a horizontal axis mark of the operative eye in the sitting position is parallel to a horizontalline of a cross mesh of an eyepiece; the femtosecond laser unit is used for carrying out femtosecond laser cutting. The full femtosecond laser system for eyeball spin correction solves the problem that an existing full femtosecond laser system fails to correct eyeball spin.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a full femtosecond laser system for correcting eyeball spin. Background technique [0002] When the existing German Zeiss VisuMax femtosecond laser system performs SMILE surgery (femtosecond laser small incision corneal stromal lens extraction), only the negative pressure suction disc is used to attract and fix the eyeball to prevent eye movement during the operation. The device does not have eye recognition The positioning system cannot actively compensate the spin angle (rotation along the visual axis) of the eyeball after the conversion from the sitting position to the supine position, resulting in a deviation of the astigmatism cutting axis and affecting the quality of the operation. Faced with this problem, a full femtosecond laser system that can correct the eyeball spin and compensate for the spin of the eyeball after the transition from sitting to supine is needed in prac...
