Embodiment Construction

[0043] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] Due to the current mass production of intraocular lenses, it is difficult to adapt to individualized eye problems of patients, and patients have poor experience in use. The invention provides a method for manufacturing intraocular lenses.

[0045] The method and corresponding equipment will be described in detail below through basic design, extended design and replacement design.

[0046] A method of making an intraocular lens, such as figure 1 As shown, the steps include:

[0047] Step 110, determine (select) the degree of intraocular lens according to the obtained eye examination data;

[0048] The eye examination data may include: axial length of the eye, corn...

Abstract

The invention relates to the field of intraocular lens manufacturing and is particularly suitable for a personalized manufacturing method of an intraocular lens. The manufacturing method comprises the following analysis steps: determining an intraocular lens degree according to acquired eye examination data; designing an intraocular lens three-dimensional shape according to the intraocular lens degree and the eye examination data; carrying out data slicing on the intraocular lens three-dimensional shape; printing data slices by utilizing photocuring 3D printing to obtain an initial product of the intraocular lens; and carrying out aftertreatment on the initial product of the intraocular lens to obtain a finished intraocular lens product. According to the manufacturing method, the intraocular lens degree is determined according to the eye examination data, the intraocular lens three-dimensional shape is correspondingly designed, and then, the intraocular lens is obtained through printing by a photocuring 3D printing technology. Since being acquired by the eye examination data, the intraocular lens has the pertinence, is closer to an own eye refraction state and anterior segment image information, is obvious in personalized use effect and can improve the visual quality and the intraocular lens implanting stability of a patient subjected to an intraocular lens implantation to the maximum.

Description

technical field [0001] The invention relates to the field of intraocular lens production, in particular to a production method suitable for individualized intraocular lenses. Background technique [0002] The intraocular lens is an indispensable alternative implantable medical consumable in ophthalmic cataract extraction surgery. It has high light transmittance and conforms to the characteristics of the diopter of the human eye, making it a good substitute for the aging natural lens of the human eye, so that cataract extraction Surgical patients obtain good postoperative visual effects. At present, the ideal material for manufacturing intraocular lens is polyhydroxyethyl methacrylate (HEMA), which not only has good light transmittance of the first generation intraocular lens material polymethacrylate (PMMA), but also because of its softness, The foldable feature greatly reduces the incision of cataract surgery, which is helpful for reducing surgical trauma, improving postop...
