Problems solved by technology

In the design of intraocular lens, in principle, it should be designed according to the corneal condition of each patient, but this is unrealistic for mass production. The actual intraocular lens design is based on a certain corneal model

Embodiment Construction

[0036] In one aspect of the invention, an artificial lens is disclosed that can be used, for example, as a contact lens worn on the outside of the eye or as an intraocular lens implanted in the eye that can replace A natural lens that becomes cloudy, or is implanted between the cornea and the natural lens to correct vision.

[0037] In the following, the principle of the present invention will be specifically described for the case where an artificial lens is implanted in the eye to replace the natural lens. In this case, the artificial lens of the present invention is also called an aphakic intraocular lens. The principles of the invention also apply analogously in the case of artificial lenses used as contact lenses or implanted between the cornea and the natural lens (ie as phakic artificial lenses).

[0038] The inventors of the present invention found that the order of magnitude of image blur caused by different refractive powers at different apertures is much higher than...

Abstract

The invention discloses an artificial lens applied to an imaging light path of eyes. The artificial lens comprises an optical part and is characterized in that the front surface and/ or the rear surface of the optical part is non-spherical surface through which the refractive power at different apertures of the eyes can be basically kept constant after the artificial lens is applied to the imaging light path of the eyes. The invention also discloses a method for manufacturing the artificial lens.

Description

technical field [0001] The present invention relates to artificial lenses and methods for their manufacture. The artificial lens of the present invention can be used as a contact lens worn outside the eye or as an intraocular lens implanted in the eye. Background technique [0002] Artificial lenses can be used as contact lenses worn outside the eye or as intraocular lenses (IOLs) implanted in the eye. [0003] An intraocular lens (IOL) is an artificial lens that can be implanted in the eye to replace the natural lens in a person's eye that is clouded by cataract disease, or in refractive surgery to correct the person's vision. According to the combination of optics and support haptics, soft foldable intraocular lenses are usually divided into one-piece and three-piece. A one-piece soft foldable intraocular lens, the optic and the haptics are integral and made of the same piece of soft material. In the three-piece soft foldable intraocular lens, the optical part and suppo...
