Problems solved by technology

[0010] 1) For patients with high myopia, due to the axial growth of the eye axis, posterior staphyloma is common, which will cause large errors in the measurement of eyeball biological parameters, and then lead to inaccurate calculations;
[0011] 2) The postoperative reserved diopter of high myopia is often different from that of emmetropia or low myopia. The target diopter of emmetropia or low myopia is 0, while high myopia often reserves low myopia after surgery to assist For nearsightedness, most of the existing formulas are optimized based on the target diopter being 0 or near 0. For patients...

Embodiment 1

[0036]Among the latest generation of intraocular lens calculation formulas, the Barrett Universal II formula is recognized as the most accurate calculation formula. Therefore, based on the Barrett Universal II formula, we calculate the intraocular lens diopter and predict the diopter after operation, as well as high myopia cataract Multiple biometric parameters of 1450 eyes in the database, machine learning using artificial intelligence XGBoost algorithm. The included learning features include: age, eye axis, anterior chamber depth, corneal steep axis curvature and axial position, corneal flat axis curvature and axial position, intraocular lens implantation power and A constant, and the prediction of Barrett Universal II formula back calculation Diopters. The learning goal is the real diopter of the patient more than one month after surgery. The model building process is divided into data cleaning, preprocessing, consideration of whether each learning feature is included in t...

[0040] A 55-year-old female patient with right eye high myopia complicated with cataract, right eye axis 31.31mm, anterior chamber depth 3.78mm, corneal flat axis curvature 43.51D, axial position 10°, corneal steep axis curvature 45.01D, axial position 100°, proposed Implanted intraocular lens MCX 11ASP, A constant 119.4, planned to reserve -2.50D after operation, substituted into Barrett Universal II formula, obtained +4.0D predicted diopter of intraocular lens was -2.94D, and substituted into the artificial intelligence assisted optimization height of the present invention Myopia intraocular lens diopter calculator, obtained the predicted diopter of +4.0D intraocular lens to be -2.56D, then implanted +4D intraocular lens after intraoperative cataract suction, and subjective optometry one month after operation to get the actual postoperative The diopter is -2.50D. Patients have good vision, quick recovery and high satisfaction. This calculator is more accurate in predicting ...

[0042] A 56-year-old male patient with left eye high myopia complicated with cataract, left eye axis 27.87mm, anterior chamber depth 3.42mm, corneal flat axis curvature 41.93D, axial position 3°, corneal steep axis curvature 43.32D, axial position 93°, proposed Implanted intraocular lens Rayner 920H A, A constant 118.6, reserved -3.5D after the planned operation, substituted into Barrett Universal II formula, obtained +14.0D predicted diopter of intraocular lens is -3.11D, and substituted into the artificial intelligence assisted optimization of the present invention The intraocular lens diopter calculator for highly myopic eyes obtained the predicted diopter of +14.0D intraocular lens as -3.65D, so a +14.0D intraocular lens was implanted after intraoperative cataract extraction, and the actual optometry was obtained one month after the operation. The postoperative diopter was -4.25D. The prediction error of this calculator for the postoperative reserved diopter of high myopia...

Abstract

The invention relates to an artificial intelligence-assisted optimized highly myopia intraocular lens degree calculator using method, which comprises the following steps: S1, inputting basic information of a patient, and substituting the basic information into a Barrett calculation formula to obtain an IOL degree and a corresponding predicted diopter; s2, inputting the obtained IOL degree and diopter into XGBoost model carrying software; s3, outputting the optimized predicted diopter based on the long eye axis; and S4, comparing the optimized predicted diopter with the target diopter. The method has the advantages that the degree of the intraocular lens can be accurately calculated and the postoperative reserved diopter can be predicted before the high-myopia intraocular lens implantation operation, myopia drift or hyperopia drift occurring after the operation can be effectively reduced, and the visual effect after the intraocular lens implantation operation is improved; the postoperative refraction state of a patient with high myopia can be accurately predicted, and the satisfaction degree of the patient is increased.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an artificial intelligence-assisted and optimized high myopia intraocular lens degree calculator. Background technique [0002] During cataract extraction, it is often necessary to select the appropriate reserved diopter and intraocular lens power according to the calculation formula. High myopia is defined as an eyeball with an axial length > 26 mm. Due to a series of special eyeball structural changes in high myopia, such as axial growth, posterior staphyloma, etc., the formula for calculating the intraocular lens power for high myopia should be different from Non-high myopia. At present, the commonly used formulas in the world are generally more suitable for normal axial eyes, but when applied to highly myopic eyes, the prediction error will increase significantly, and refractive accidents such as postoperative hyperopia drift will appear. At present, there are many calc...
