Abstract
The utility model relates to cycloplegic for relieving a highly adjusting state of ciliary spasm and a crystalline lens, which is the effective method of ophthalmology prevention and myopia therapy. But the side effects of mydriasis, photophobia, far movement of a near point, spherical aberration, etc. can be generated simultaneously, a patient who is treated can not normally work and read in a near distance. The utility model provides a pair of artificial iris glasses with the function of iris physiological optics. The patient who is treated wears the pair of artificial iris glasses simultaneously, the effect that ciliary muscle medicine is used for treating the myopia in a paralysis mode can be achieved, but also the generation of serious photophobia resulted from mydriasis, and the side effects of the far movement of a near point, the spherical aberration, etc. can be overcome. The pair of artificial iris glasses has the advantages of convenient use, good reaction and convenient popularization.
Description
The utility model relates to the special use of a kind of ciliary muscle medicine paralysis myopia, the artificial iris mirror with iris physiological optics function.Belong to medical optical instrument.
The incidence of disease of myopia in the teenager is very high.According to statistics, the incidence of disease of myopia in the pupil is 35%; The incidence of disease in middle school student is more than 60%.Can myopia effectively prevent and the important medical problem is not only in treatment, also is the social concern that paid close attention to by people.Be engaged near work, reading etc. for a long time, cause crystalline lens always to be in the height adjustment state, ciliary muscle is spastic contraction for a long time.Simultaneously, eyeball is looked nearly thing for a long time and is converge like the spokes of a wheel at the hubly excessively made extraocular muscle continue oppression eyeball, causes axis oculi long, and this is to cause near-sighted main cause.Clinical ophthalmology is used cycloplegic (as atropine Atropine, Tropicamide Tropicamide) both at home and abroad, and the eye ciliary muscle that can relax is effectively removed ciliary spasm and lenticular height adjustment state, and the crystalline lens convexity weakens.Atropine is competitive m receptor blocking agent, can act on the sphincteral choline receptor of a ciliary muscle and iris pupil, and the blocking-up parasympathetic nerve makes ciliary muscle and sphincter pupillae loose to the domination function of ciliary muscle and sphincter pupillae.Because cycloplegic can fundamentally be removed ciliary spasm and lenticular height adjustment state, so, be the prevention commonly used of present ophthalmology and treat near-sighted method.But cycloplegic blocking-up parasympathetic nerve makes ciliary muscle and sphincter pupillae lax, and is subjected to the dilator muscle of pupil of sympathetic innervation to keep original tensity relatively the domination function of ciliary muscle and sphincter pupillae, makes mydriasis, regulates paralysis.The pupil height looses big, patient's height photophobia, and near point far moves and produces spherical aberration etc., normally closely operation, reading etc., therefore, this effective methods of treatment patient is difficult for accepting, and applies being restricted.
Task of the present utility model provides the special use of a kind of ciliary muscle medicine paralysis myopia, the artificial iris mirror with iris physiological optics function.The artificial iris mirror is the contact lens that adopts hydrophilic contact lens,soft (hydroxyethyl methylacrylate HEMA) material.The eyeglass water percentage is 40%; Optic diameter: 13.8mm; Center of lens thickness: 0.07mm; Eyeglass intrinsic curvature: 8.4mm; Center of lens transparent optical school district diameter: 2mm; Lens optical functional areas overall diameter: 9mm.The curer wears the artificial iris mirror, both can reach the effect that continues ciliary muscle medicine paralysis treatment myopia, can overcome the height photophobia that produces because of mydriasis again, and spinoffs such as near point far moves, spherical aberration, make the curer can keep normally closely operation, reading etc.
The utility model specifically describes with the following Examples.
Fig. 1. be the positive side of the utility model artificial iris mirror position synoptic diagram.
Fig. 2. be artificial iridoscope principle schematic.
According to shown in Figure 1, artificial iris mirror (1) is the contact lens that adopts hydrophilic contact lens,soft (hydroxyethyl methylacrylate) material.Optic diameter: 13.8mm (2); Center thickness: 0.07mm (3); Intrinsic curvature: 8.4mm (4); Has different dioptric central, transparent optical area diameters: 2mm (5); Sepia optical function area overall diameter: 9mm (6).
According to shown in Figure 2, when using ciliary muscle medicine paralysis myopia, eye ciliary muscle (7) paralysis is lax, and crystalline lens (8) convexity weakens, and iris (9) sphincter pupillae is lax, mydriasis (10).Artificial iris mirror (1) covers whole cornea (11), have different dioptric central, transparent optical zone (5) and sepia optical function area (6), can overcome the height photophobia that produces because of mydriasis (10) effectively, and spinoffs such as near point far moves, spherical aberration, make the curer can keep normally closely operation, reading etc.
Claims (2)
1. artificial iris mirror (1) with iris physiological optics function, it is characterized in that: the eyeglass setting has the sepia optical zone (6) and different dioptric central, transparent optical zone (5) of iris physiological optics function.
2. claim 1 is described. the artificial iris mirror, and its feature also is: sepia optical zone (6) overall diameter that eyeglass is provided with is in 8.5～11mm scope; The diameter of central, transparent optical zone (5) is between 1.0～4mm.
