Abstract

The invention provides a method for predicting a diopter adjustment value (Nomogram value) in an SMILE (Small Incision Lenticule Extraction) refractive surgery based on a Softmax regression algorithm.The method comprises the steps that screening, discretization and other pretreatment are carried out on original data, the discretized Nomogram value serves as a category label; a Softmax hypothesisfunction and parameter matrixes of the Softmax hypothesis function are initialized, and a gradient descent method is utilized to obtain the parameter matrix minimizing a cost function; the optimal parameter matrix is substituted into the Softmax hypothesis function to obtain a regression model; and the regression model is utilized to predict a Nomogram reference value applied in an SMILE surgery plan. The method can predict the Nomogram value of a new case more accurately and more stably within the range of the error that the SMILE surgery allows, and provide reference and help for doctors tomake surgery plans.

Description

technical field [0001] The invention belongs to the field of ophthalmic refractive surgery and relates to machine learning technology, in particular to a method for predicting Nomogram values ​​in SMILE surgery based on a Softmax regression algorithm. Background technique [0002] There are more than 1.5 billion people in the world suffering from myopia. In my country, the incidence of myopia is increasing year by year. Finding safe, effective and accurate correction methods has become a research issue of great concern in the field of ophthalmology. At present, corneal refractive surgery is one of the main methods to correct myopia. Among them, SMILE femtosecond laser small incision lens extraction is a new surgical procedure, and its effectiveness and safety have been widely confirmed. However, the human eye is a biological individual, and a relatively unified surgical design and treatment plan cannot be suitable for all individuals. At the same time, the corneal morphologi...
