Novel posterior chamber intraocular lens based on innovation biocompatibility hydrophobic material

Abstract

The invention relates to an aspherical intraocular lens. Specifically, the intraocular lens comprises an optical part with an optical surface and a plurality of belts connected with the optical part. The optical surface of the optical part is aspherical. After convergence light rays refracted by corneas radiate into the intraocular lens under the 5 mm effective optical aperture, the spherical aberration represented by the intraocular lens is -0.1-0 [mu]m.

Description

technical field

[0001] The invention relates to an aspheric artificial lens, in particular to a weak aspheric artificial lens. Background technique

[0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. What is stated in this section may or may not constitute prior art.

[0003] An intraocular lens (IOL) is an artificial lens that can be implanted in the eye to replace the eye's natural lens, which is clouded by cataract disease, or used in refractive surgery to correct a person's misaligned vision.

[0004] Most of the existing intraocular lenses are made of flexible materials, because they are usually folded or curled to be implanted in the eye through a 2-3 mm incision after reducing their area during surgery, so they are also called folded lenses. After the intraocular lens is implanted in the human eye, the relative position in the capsular bag is maintained by the interaction force between the hap...
