Abstract

The invention discloses a cataract surgical navigation system. The cataract surgical navigation system is characterized by comprising the following steps of S1, preoperative measurement: performing data measurement with a corneal topography instrument; S2, formulating an optimized surgical scheme; S3, comparing eyeball information during operation; S4, locating an eyeball through iris or scleroticblood vessels during the operation; S5, importing the data into an operating room microscope; S6, finishing each step of the operation according to image data by a surgeon. By adopting the cataract surgical navigation system, an eye image of a patient is collected before the operation, data such as a position suitable for implanting an artificial lens, an incision position and the axial positionof an implanted astigmatism-correcting artificial lens of the patient can be calculated, and are then imported into the operation room microscope, so that the surgeon can finish each step of the operation according to the image data, thereby achieving an optimized postoperative visual effect.

Description

Technical field [0001] The invention relates to the technical field of cataract surgery, in particular to a navigation system for cataract surgery. Background technique [0002] Common methods or traditional practices in the industry and detailed steps: [0003] 1. Intracapsular cataract extraction (ICCE): a large incision cuts the limbus of the cornea and sclera, freezes the lens with a freezing head after entering, and pulls it outwards to break the suspensory ligament and deliver the lens. [0004] 2. Extracapsular cataract extraction (ECCE): switch-type capsulotomy to deliver the lens. [0005] 3. Phacoemulsification lens extraction (Phaco): continuous ring capsulorhexis, phacoemulsification of lens nucleus, perfusion and suction of lens cortex, implantation of intraocular lens. [0006] The main disadvantages of existing methods: [0007] 1. Existing cataract surgery may not be suitable for everyone. Senile cataract develops to a visual acuity of less than 0.3, lens opacity in the ...
