Abstract:
The present invention discloses a method for preparing an aspheric vision correction lens with controllable peripheral defocus. It comprises the steps of: calculating and determining the conditions required for the formation of myopic defocus of a human eye, by examining the shape of the retina of the human eye, the amount of peripheral defocus of the naked human eye or the amount of peripheral defocus of the human eye with a lens; formulating a plan of distribution of the refractive power of the vision correction lens varying with the aperture, according to the conditions obtained for myopic defocus; and making the vision correction lens according to the obtained plan of distribution of the refractive power of the vision correction lens such that after the refractive power of the vision correction lens is added to the human eye, the distribution of the refractive power of the entire eye on the retina is greater in the peripheral region of the retina than in the central region of the retina, and falls in front of the retina, to form myopic defocus. The present invention also discloses a vision correction lens worn outside the eye, an orthokeratology lens and an intraocular lens prepared according to the method. The present invention further discloses a diagnosis and treatment method that utilizes myopic peripheral defocus to control and retard myopia growth.

Claim (Index 5):
The method for preparing an aspheric vision correction lens according to  claim 1 , characterized in that, in said step (1), the amount of peripheral defocus of the naked human eye (\u0394D1) and the amount of peripheral defocus when a lens is worn (\u0394D3) are both measured by an ophthalmic test apparatus; the amount of peripheral defocus of the aspheric vision correction lens (\u0394D2) is known; when the amount of peripheral defocus provided by the vision correction lens (\u0394D2) plus the amount of peripheral defocus of the naked human eye (\u0394D1) is greater than or equal to 0, the human eye forms myopic peripheral defocus; when the amount of peripheral defocus of the human eye with a lens (\u0394D3) is greater than 0, it indicates that the amount of defocus of the trial lens meets the conditions for myopic peripheral defocus of the human eye.
