Description
Technical field
The utility model is related to a kind of ophtalmic treatments instrument, more particularly to a kind of pseudo-myopia correcting spectacle lens.
Background technology
According to optical principle, imaging in extraneous object distance and human eye is away from being inversely proportional, the long-term close eye of people, just
The synchronous near reflex regulative mechanism for rationality of looking unfamiliar can be mobilized, this process is voluntarily completed or make up by Diopter accommodation reaction, this
One process is medically referred to as regulation reaction.In the regulation course of reaction of this physiological, human eye will reflect in succession
Property ciliary muscle contraction, refractive power enhancing, the increase of crystalline lens spheric curvature, the optical axis convergence elongation of two eyeballs, pupil contraction etc..
By this series of physiological regulation reaction, clearly image can not only be formed in retina quickly, two can also be imaged onto
On the symmetrical position of eyes retina.Then, by being felt the photosensory cell of activation, neuro-vision path is passed through（Depending on road）, by
The information of imaging is transmitted to brain occipital lobe cortical visual centers, finally obtains binocular vision, and the object at this time seen just can be very
It is clear.But, this complicated physiological reaction is when regulation mechanism runs into the destruction of internal, external various factors, such as a long time
Fatigue eye, can not when causing the regulation of ciliary muscle and eye socket periphery orbiculares nervous and spasm, then seeing longer-distance object
Loosen regulation, long must change the dioptric system of human eye, cause it is ametropia, and according to the destruction of Diopter accommodation reaction system
The difference of situation and degree, suffers from heterogeneity, different degrees of pseudo-myopia in succession.
Clinically, eyeball has inherent and external two groups of muscle, and inherent muscle is iris（Sphincter pupillae）And ciliary muscle,
The size and lenticular focal length of adjustable pupil.External muscle has six, can control the rotation of eyeball.
In China's adolescent myopia rate about close to 70%, TV is mainly seen for a long time, is surfed the Net, and is played game etc. and is not noted using eye
Cause, also there is the fault for seeing written word, books to put it is excessively near from eye, lighting condition is bad etc., these can all make eyelash
Muscle contracts last in shape body, crystalline lens F degree increases, and makes intraciliary muscle in tension, becomes F crystalline lens
It can not cherish and arrive normal condition again, thus cause pseudo-myopia.
Before this, the common method for rescuing pseudo-myopia mainly has：
1st, PRK operation for myopia, by cutting cornea, produces cornea flap, then take laser action
In cornea, reach and rescue ametropic purpose.PRK is a kind of purple of only 193 nanometers of wavelength invisible to the human eye
Outer Line beam, its characteristic is that photon energy is big, and wavelength is extremely short, and the penetration power to tissue is extremely weak, will not penetrate intraocular, is only organized
Surface absorption, or damage atomic, excimer laser cornea refractive treatment technology (LASIK technology) lossless to surrounding tissue, is to use
Superficial keratectomy tissue is fabricated to one by a kind of special extremely accurate miniature corneal lamellar diced system (abbreviation keratome)
After cornea flap with the base of a fruit, upset cornea flap, under the control of the computer, the corneal stroma under valve is intended with PRK to remove
Portion of tissue accurately gasify, then in subcornea wash and cornea flap is resetted, changes the form of anterior surface of cornea with this,
Adjust cornea refractive power, enable ambient be converged to exactly on eyeground as, reach the purpose of correction of myopia, it is this to cut
It is very risky although except the method for part cornea is quick, there is certain damage to eyes.
2nd, eyeglass is rescued, and Dai Jing is the most common method of children's correction of myopia, and the principle with mirror, which should be taken, can equally make
The eyesight of myopia rescues the most low eyeglass of best vision, but the item that should be noted is more, adheres to that the time is long, especially numerous
Do not notice that too much, surely produced a desired effect so differing mostly in trivial life yet.
PRK operation for myopia and eyeglass rescue the mesh that although two methods are attained by correction of myopia at present
, but all also there is certain defect.
