Background technique
The problem of adolescent myopia, is increasingly severe, and in order to solve the problems, such as myopia, people provide very from different perspectives
More solutions, wherein influencing a bigger solution is the Ortho-K for originating from the U.S. the 1960s,
Modern cornea moulding mirror use gas permeability hard contact lens added i.e. in poly- polymethacrylic acid methyl ester silica gel or fluorine silica gel for
Material is fabricated to spectacle lens, inverts geometry designs, i.e. base curve area, reversion arc area, positioning arc area and periphery using 4th areas, seven arc
Area.The curvature in base curve area is flat compared with Central corneal curvature.It is steep compared with base curve area to invert arc area, difference and degree between two sections of curved rates
The number range of decrease is related.Positioning arc area is made of multi sphere section, to improve the identical property in lens orientation arc area and cornea, reduces displacement.Week
The area Bian Hu is flat compared with positioning arc area, and outer has side to stick up, and exchanges convenient for tear, the effect provided positioned at eyelid outside Ortho-K
Power allows the curvature of cornea to be changed according to the shape of Ortho-K.
But its shortcomings that is also obvious: 1, near-sighted Crack cause is in addition to corneal curvature becomes larger, and there are also eyeballs
Anteroposterior diameter is elongated.Ortho-K not can control the elongated problem of anteroposterior diameter of eyeball, therefore the degree of A nearsighted person still can
It is slowly increased.It 2, can be to specific biological tissue's environmental effects and effect, biological tissue pair after biomaterial merging human body
Biomaterial also can have an impact and act on, therefore itself mucous membrane of its compatibility and eyes is still had any different.3, Ortho-K
Although eyeglass has selected oxygen permeability material, but oxygen delivery capacity still can not be mentioned in the same breath with human body natural's oxygen delivery capacity, and oxygen flow
Coefficient is quite important for corneal health, and the transmitance of oxygen influences whether the physiological function of keratocyte.4, Ortho-K
Wearing process it is more complicated, wear after eyes foreign body sensation is strong, wears cost is generally higher and follow-up maintenance is at high cost etc..
5, the radian of Ortho-K is fixed, must replace eyeglass after eyesight obtains improving.
In order to solve the deficiency of Ortho-K, many people contemplate the mode from oppression eyeball outside eyelid and adjust to reach
Save the purpose of corneal curvature, eyeball back/forth diameter.But having the following problems for oppression eyeball: mesh is carried out outside current slave eyelid
Preceding that all instrument is fixed on head using fixing belt, the eyeshield frame elasticity fixed with head is adjusted by this fixing belt,
The relative distance for pressing spherical convex surface and eyeball simultaneously can also change while fixing belt is adjusted, elastic certain journey of fixing belt
Determine that pressing spherical convex surface is applied to epibulbar pressure on degree.And different people is because the difference such as age, constitution is to fixing belt
Elastic perception it is also different, ensure safety with it is comfortable under the premise of to press the relative distance of spherical convex surface and eyeball be also different
, and the highly brittle hyposensitiveness sense of eyes, there is also the different situations of right and left eyes myopic degree, only with user for fixing belt pine
Tight feeling decision is obviously unreasonable to the pressure of eyeball, and effect is poor, safety is low.
