Embodiment Construction

[0028]The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the ophthalmic surgery navigation system 2 of the present invention provides eye position, rotation and other information for the doctor during the operation through the integration with the surgical microscope 20, and assists the doctor to perform the operation. Wherein, the operating microscope 20 is a standard microscope system currently used clinically, and mainly includes an eyepiece system 21 , a spectroscopic system 22 and an objective system 23 . The objective lens system 23 focuses the light beam on the patient's eye 24 to realize clear imaging. The beam splitter system 22 divides the beam into two or more paths, one of which leads to the eyepiece, and the other leads to the video recording system 3 of the surgical navigation system. This path is the path of the pres...

Abstract

The invention provides an ophthalmic surgery navigation system. The ophthalmic surgery navigation system provides eye position and rotation information for an intraoperative doctor through integrationwith a surgical microscope, and assists a doctor in performing surgery. According to the system, surgery video is obtained in real time based on an artificial intelligent image processing algorithm,the current frame of image is tracked based on extraction of a plurality of target areas or features, accumulated errors are corrected according to reference images, and finally, information such as eye scaling, displacement, rotation and non-rigid deformation is determined. Eye position information is projected into a surgical microscope, real-time, continuous, automatic and accurate navigation of surgery is achieved, manual marking is avoided, personalized ophthalmic surgery is achieved, surgical quality is improved, and postoperative visual recovery of patients is improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence image processing, in particular to an ophthalmic surgery navigation system. Background technique [0002] Eye surgery is a common method for treating eye diseases. For example, cataract surgery removes the cataract in the diseased eye and completes the replacement of the intraocular lens through steps such as incision, capsulorhexis, and phacoemulsification. Refractive cataract surgery corrects corneal astigmatism by replacing the astigmatic intraocular lens while removing the cataract, improving postoperative uncorrected visual acuity. Astigmatic intraocular lenses have directionality, especially multifocal intraocular lenses. It is necessary to ensure that the lens is centered and the astigmatism axis is consistent with the preoperative calculation direction during surgery. However, the measurement of the patient's eye biological parameters (including astigmatism) is generally completed ...
