Embodiment Construction

[0084] In a first embodiment, an iris (intraocular) covering implant performs a covering or overlapping function to the iris, and the covering implant is intended to be secured to the iris. Since the iris is always covered by at least a part or part of the implant, regardless of the embodiment and function / application of the implant, the term "covering implant" will be used in the rest of the description.

[0085] here, as Figure 1 to Figure 7 As shown, the covering implant is made of two parts. The covering implant is made of a biocompatible material or a combination or mixture of biocompatible materials. For example, covering implants are made of silicon or hydrophilic acrylic or hydrophobic acrylic or elastomers and can be, for example, silica or EMA (ethyl methacrylate) or HEMA (hydroxyethyl methacrylate) ) or a combination (copolymer) of the two preceding examples reinforced cross-linked polydimethylsiloxane (material suitable for medical use).

Abstract

The invention concerns an iris cover implant intended to cover at least partially the iris of an eye, the cover implant comprising a body (10) having a first face that is an opaque face and, on an opposite second face, at least one attachment member that extends outwardly from the body and is fixed thereto, the at least one attachment member comprising at least two clamping portions that are ableto attach the body to an iris of an eye by clamping.

Description

technical field [0001] In particular, the present invention relates to iris covering implants. Background technique [0002] Young people's eyes can naturally focus from distant objects to near ones. The underlying mechanism of this focus is known as the adaptive process. This adaptation process consists of three main aspects: first, as objects approach, the eyeballs converge, then, for a given brightness, pupil constriction increases, and finally, lens shape is adjusted by ciliary muscle contraction. [0003] As the eyes naturally age, it becomes increasingly difficult for the eyes to adjust to near objects. As they age, study subjects gradually lose their near vision and are only able to create sharp images of distant objects. This natural visual influence is known as presbyopia. It is estimated that by 2020, approximately 2 billion people will have to deal with such optical effects. Presbyopia is experienced as a person's blurred vision and occurs frequently when the...
