Embodiment 1

[0035] Please refer to the attached Figure 4 , attached Figure 4 It is a structural block diagram of an intelligent prediction system for high myopia cataract surgery prognosis of the present invention. The high myopia cataract operation prognosis intelligent prediction system includes a storage device 1 , an evaluation module 2 , an examination module 3 and a test evaluation adjustment module 4 .

[0036] Storage device 1: used to store the information in the training set, including basic information of the patient, preoperative best corrected visual acuity, axial length, corneal astigmatism, anterior segment photos, fundus photos, fundus OCT and postoperative best corrected visual acuity;

[0037] Evaluation module 2: According to the degree of lens opacity in the anterior segment image, make LOCSIII classification, build a deep learning model for the degree of lens opacity, and evaluate the degree of fundus lesions according to the results of fundus photography and OCT; ...

Embodiment 2

[0046] Construct the deep learning model of the intelligent prediction system, which is composed of two networks: evaluation and prediction; the evaluation network makes LOCSIII classification according to the degree of lens opacity in the anterior segment image, and builds a deep learning model for the degree of lens opacity. Evaluate the degree of fundus lesions and build a fundus evaluation model; the deep learning model of lens turbidity is a hierarchical regression algorithm based on convolutional neural network (CNN). The deep learning framework adopted is based on VGG, Inception, ResNet, etc. Since postoperative visual acuity prediction is closely related to the degree of fundus lesions, the system features image enhancement algorithms in the fundus evaluation model to reduce the impact of refractive media turbidity on image quality, and identify and grade all fundus lesions as much as possible. At the same time, according to the fundus photo and the corresponding image ...

Embodiment 3

[0051] The female patient, 46 years old, had blurred vision in the right eye for 1 year. She was treated in our hospital and denied diabetes, hypertension, other eye diseases or surgery history. Ophthalmological examination showed that the best corrected visual acuity of the right eye was 0.4, the axial length of the eye was 27.1mm, and the corneal astigmatism was -0.58D. The doctor entered the patient information and clinical data into the high myopia cataract surgery prognosis intelligent prediction system, and the system evaluation result was: high myopia cataract in the right eye (LOCSIII grade N3, no obvious abnormality in the fundus), and the estimated postoperative best corrected visual acuity range was 0.8 -1.0. The patient agreed to the operation, and the best corrected visual acuity of the right eye was 1.0 one day after the operation, and the patient was satisfied.

Abstract

The invention relates to a high myopia cataract surgery prognosis intelligent pre-judging system. The system can evaluate the cataract turbidity degree of ocular anterior segment photos, the fundus condiction is evaluated according to fundus photos and fundus OCT images, and then other clinical data of a patient is integrated to provide prediction for the optimal corrected visual range of the patient suffering from high myopia cataract. The system has the advantages that high accuracy is achieved through repeated tests and parameter adjustment, problems that clinical doctors and the patient concern most are solved, the clinical doctors can be helped to accurately estimate the postoperative visual acuity of the patient, visual postoperative result prediction is provided for the patient, thedifference between expectation of the patient and results is reduced, and the satisfaction degree of the patient is improved.

Description

technical field [0001] The invention relates to the technical field of medical artificial intelligence, in particular to an intelligent prediction system for the prognosis of highly myopic cataract surgery. Background technique [0002] High myopia cataract refers to cataract patients whose axial length is greater than or equal to 26mm. Such patients usually have myopia exceeding -6.0D or even -30.0D before surgery, and high myopia is not only a change in diopter, but may be combined with a series of pathological changes , including leopard-like fundus, posterior staphyloma, lacquer cracks, peri-optic disc atrophy, chorioretinal atrophy, choroidal neovascularization, retinoschisis, and macular hole. For cataract patients and surgeons, postoperative visual acuity and visual quality are the most important concerns. However, due to the complexity of fundus lesions in patients with high myopia and the opacity of the refractive medium caused by cataract, the details of fundus les...
