Embodiment 1

[0038] The establishment process of the high myopia cataract intraocular lens accurate selection system of the present invention is as follows figure 1 As shown, the details are as follows:

[0039]1. Construct a deep learning model for the calculation of high myopia cataract intraocular lens diopters; provide the machine with a large amount of clinical data and corresponding postoperative diopters for learning, each data includes the patient's age, gender, refractive surgery status, vitreous body State, preoperative diopter, axial length, depth of anterior chamber, lens thickness, white-to-white distance, corneal curvature radius, implanted intraocular lens type, power and postoperative diopter, the machine constructs based on different artificial The power calculation model of the lens type, through repeated training and debugging of large samples in the training set, and through the test set test to meet the prediction accuracy requirements, and finally successfully build a...

Embodiment 2

[0051] A 58-year-old male patient with blurred vision in his right eye for 1 year. He was highly myopic in the past and wore -10.0D glasses. He visited our hospital and was diagnosed with high myopia in the right eye complicated with cataract. He denied any history of eye surgery. Ophthalmological examination showed that the axial length of the right eye was 27.82mm, the corneal refractive power K1=41.83D, K2=42.44D, the anterior chamber depth was 2.78mm, the white-to-white distance was 11.70mm, and the lens thickness was 3.25mm. The patient usually likes to read, and close-up eye time accounts for 60% of daily life. After inputting the information into the highly myopic cataract intraocular lens precision selection system, the system judges that the reserved diopter of the patient after surgery is -3.5D, which is suitable for implantation of ZCB0015.5D artificial lens lens. One day after the operation, the uncorrected distance visual acuity of the right eye was 0.3, the uncor...

Embodiment 3

[0053] A 75-year-old female patient had blurred vision in her left eye for 10 years. She was highly myopic in the past but never received glasses. She visited our hospital and was diagnosed with high myopia in the left eye complicated by cataract. She denied any history of eye surgery. Ophthalmological examination showed that the axial length of the left eye was 31.32mm, the corneal refractive power K1=41.44D, K2=41.86D, the anterior chamber depth was 3.46mm, the white-to-white distance was 12.95mm, and the lens thickness was 3.46mm. The patient used to be a farmer, but now he spends more time watching TV at home, and basically has no need for close-up eyesight. After inputting the information into the highly myopic cataract intraocular lens precise selection system, the system judged that the reserved diopter of the patient after surgery was -1.0D, which was suitable for implanting the HumanOptics MC X11ASP 3.0D intraocular lens. One day after the operation, the uncorrected d...

Abstract

The invention relates to an accurate selecting system for a high myopia cataract artificial crystalline lens. The selecting system is characterized by comprising the components of a data module whichsuccessively constructs a high myopia cataract artificial crystalline lens number calculating model; an evaluating module which determines the target diopter of a patient; a matching module which determines a most suitable artificial crystalline lens type; and a selecting module which quickly and accurately calculates the required artificial crystalline lens diopter. The system has advantages of improving artificial crystalline lens selecting accuracy, improving artificial crystalline lens selecting efficiency in a cataract surgery; realizing high accordance for patient requirements, selectingthe most suitable target diopter according to the time distribution of different daily eyes utilizing distances of the patient, satisfying the daily life requirement of the patient, satisfying the individualized requirement for selecting the artificial crystalline lens, and realizing wide service objects and high social value.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a high-myopia cataract intraocular lens precision selection system. Background technique [0002] With the development of cataract surgery technology, cataract surgery has changed from vision restoration surgery to refractive surgery. Patients' requirements for surgical effects are not only the improvement of postoperative visual acuity, but also the postoperative visual quality and removal of glasses. At present, various intraocular lenses and calculation formulas on the market have achieved good results in patients with emmetropia. The proportion of postoperative diopter errors predicted by the formulas within the range of ±0.5D can reach 90% or more, while for cataract patients with high myopia said that due to the elongation of the eye axis, the existence of posterior staphyloma and various fundus lesions, the accuracy of biometrics is poor, and the existing c...
