Abstract
An adjustable artificial lens and a contact lens comprise a lens body and a contact lens body which are made of transparent flexible material. The lens body and the contact lens body are used with an adjustable glass and provided with closed induction coils. A glass frame of the adjustable glass is internally provided with a closed drive coil which is connected with a drive power supply and a current regulator. In use, the glass frame corresponds to an eye portion of a user, and the drive coil corresponds to the outside around the induction coil. When a current in the drive coil, under the control of the current regulator, changes, magnetic field intensity around the drive coil simultaneously changes, and accordingly stress of the induction coil changes. Deformation of the induction coil drives the flexible artificial lens body or contact lens body to deform, thus transmitting characteristic is changed to meet the requirement of the user.
Description
Technical field
The present invention relates to the technical field of ophthalmic medical instrument, is a kind of adjustable artificial intraocular lenses and contact lens specifically.
Background technology
Intraocular lens is the diopter that artificial intraocular lenses is generally used for correcting the eyes that excised natural lens, i.e. the artificial intraocular lenses of so-called aphakic eye.Lentectomy is mainly used in treating cataract, and less in the situation that, is used for the treatment of myopia.This kind is used for the treatment of near-sighted intraocular lens and is the artificial intraocular lenses of so-called phakic eye, the anterior chamber of the common implanted eyes of artificial intraocular lenses of phakic eye.The aphakic eye single focus intraocular lens of standard generally has a fixing light intensity, and the combination of this kind of crystalline lens and Progressive addition lens will provide sharp vision for patient carries out distant surveillance, also can help patient to carry out in-plant examining, such as reading.
Artificial intraocular lenses of the prior art generally cannot regulate, and causes the scope of application narrower.And current adjustable artificial crystal is all by the natural zone actuation mechanism that originally drives eyes natural lens, eyes to be focused on conventionally.At present, many such design-adjustable have been proposed, comprise: the single optical device moving along optical axis (for example, WO03/015668) the many optics that, move along optical axis (for example, WO2005104995), many optics (for example, WO2005/084587 and the WO2006/118452 that comprises cubic surface; NL1025622).In addition, also have some designs that comprise flexible optical device, change lenticular optical property thereby deformation can occur these flexible optical devices, this type of design comprises: bendable material is pressed on an aperture and is changed to increase the lenticular diopter being produced.Above-mentioned artificial intraocular lenses's excursion is comparatively single and regulate result to be inaccurate, and also cannot accomplish accurately to regulate according to the wish of user.
Contact lens (contact lens), is also corneal contact lens, is that one is worn on cornea, in order to correct defects of vision or to protect the eyeglass of eyes.According to the soft or hard of material, it comprises rigid, semi-hard, soft three kinds, contact lens is not only from having brought very large improvement to convenience aspect in appearance the ametropia patients such as myopia, hypermetropia, astigmatism, but contact lens has the single number of degrees equally, too cannot be according to user need to carry out the adjusting of the number of degrees.
Summary of the invention

The present invention can also adopt following technical measures:
In two picture frames of described adjusting glasses, independently drive coil is set respectively, above-mentioned two drive coils connect respectively independently rheonome and driving power, and the two drive coils different artificial intraocular lenses of correspondence respectively.
Adjustable contact lens of the present invention, comprise the contact lens body of being made by transparent flexible material, it is characterized in that: contact lens body is used in conjunction with each other with regulating glasses, contact lens body is placed in the ophthalmic of user, and in above-mentioned contact lens body, closed induction coil is set; Regulate glasses to comprise picture frame, eyeglass and mirror lower limb, mirror lower limb forms the support component regulating between glasses and user, movable fixing between picture frame and mirror lower limb, and picture frame surrounds eyeglass fixing, closed drive coil is set in picture frame, and drive coil is connected with rheonome with driving power, regulates the electric current in drive coil by rheonome, when use, picture frame position is corresponding to the eye of user, and drive coil correspondence is enclosed in the outside of induction coil in contact lens body.
In two picture frames of described adjusting glasses, independently drive coil is set respectively, above-mentioned two drive coils connect respectively independently rheonome and driving power, and the two drive coils different contact lens of correspondence respectively.
Advantage and good effect that the present invention has are:
In adjustable artificial intraocular lenses of the present invention and contact lens, crystal body and contact lens body all support the use with regulating glasses simultaneously, in crystal body and contact lens body, miniature inductive loop is all set, and regulate the drive coil that adjustable current size is set in the picture frame of glasses, in the time that changing by the control of rheonome, the electric current in drive coil changed drive coil magnetic field intensity around simultaneously, thereby the stressing conditions of induction coil is changed, the deformation of induction coil drives flexible artificial intraocular lenses or contact lens that corresponding change of shape occurs simultaneously, thereby change the light transmission features of artificial intraocular lenses or contact lens, to reach the demand of user.
