Problems solved by technology

[0006] At present, with regard to ultra-micro-incision intraocular lenses, only a few leading foreign intraocular lens companies have this technology, but it is still blank in China
Moreover, foreign ultra-micro-incision intraocular lenses have only achieved a minimum micro-incision of 1.8mm.

Embodiment Construction

[0029] The following specific examples are only used to further explain the present invention, but the present invention is not limited to the following specific embodiments. Any changes based on these embodiments will fall within the protection scope of the present invention as long as they conform to the spirit and scope of the principles of the present invention.

[0030] According to one embodiment of the present invention, there is provided a novel intraocular lens comprising optical components. The optical component has an anterior surface, a posterior surface, and a geometric axis passing through the geometric centers of the anterior and posterior surfaces. The intraocular lens also includes two or more groups of haptics uniformly arranged around the circumference of the optical component, wherein each group of haptics includes two or more haptics, wherein each haptic includes a root end, an apex and the middle part between the root end and the apex, each haptic is con...

Abstract

The invention relates to an artificial lens. The artificial lens comprises an optical component and two or more groups of supporting loops evenly arranged around the circumference of the optical component. The optical component comprises a front surface, a back surface and the geometric axis penetrating through the geometric centers of the front surface and the back surface; each group of supporting loops includes two or more supporting loops, wherein each supporting loop comprises a top end, a root end and a middle part located between the root end and the top end, and each supporting loop isconnected with the optical component through the root end of the supporting loop; all the supporting loops of each group of supporting loops in the two or more groups of supporting loops are mutuallyconnected through the top ends of all the supporting loops; the thickness at the root end of each supporting loop is minimum, and the width at the root end of each supporting loop is maximum; the width at the root end of each supporting loop is maximum, and the width at the middle part of each supporting loop is minimum. The artificial lens has better stability in the human eye, and can be implanted from a smaller notch.

Description

technical field [0001] This invention relates to intraocular lenses, and more particularly to intraocular lenses of the form of linked haptics. Background technique [0002] Intraocular lenses are currently the most effective means of treating cataracts. [0003] With the increasing requirements of patients after surgery, intraocular lenses have developed a variety of different structural designs. Through different structural designs, different performances are brought to the intraocular lens, so that the intraocular lens can meet the needs of different patients. For example, the MI60 intraocular lens disclosed in CN101098665A can be implanted in the capsular bag of the human eye through a micro-incision through a special structural design and can maintain a stable structure. [0004] The use of phacoemulsification in the field of cataract has matured, making cataract develop from vision restoration surgery to refractive surgery. Also due to the introduction of phacoemuls...
