Description
Technical field
The present invention relates to a kind of eyesight correcting glasses, utilize periphery out of focus to control closely particularly to one
Regard the base curve district of development as aspheric Ortho-K.
Background technology
Out of focus (Defocus, out-of-focus) is to focus on the corresponding word of (focus), out of focus
Refer to that image planes, not in focus, are divided into front out of focus (before Jiao) and rear out of focus (defocused) two states.
The main cause that the myopia number of degrees increase is that axiallength extends, and often extends 1mm and increases the number of degrees
3.00 degree.Up-to-date medical research confirms, eyeball extends dependence retina (as shown at 10 in figure 1)
Periphery out of focus, according to dioptrics concept, focus fall person before retina be referred to as Myopia out of focus (as
In Fig. 1 shown in 30), the person after retina that falls is referred to as hypermetropia out of focus (as shown in Fig. 1 20).
Bathomorphic retinal centre is Myopia out of focus, and retinal periphery is hypermetropia out of focus, this regards
Nethike embrane peripheral hyperopia out of focus is to promote the ever-increasing main cause of the myopia number of degrees.
Eyeball have rely on retinal periphery imaging induction eyeball development feature, especially 18 years old with
Lower juvenile myopia, if retinal periphery is imaged as hypermetropia out of focus, retina can tend to
Picture point grows, and bulbous length just will extend, if retinal periphery is imaged as Myopia out of focus, and eyeball
Just stopping is extended.If by modern medical service method, correct retinal periphery hypermetropia out of focus or
It is artificially formed retinal periphery Myopia out of focus, it is possible to stop being continuously increased of the myopia number of degrees, with
Time find out and cause retinal peripheral defocusing reason, it is also possible to effectively prevent bathomorphic generation and progress.
Ortho-K uses " reversion geometry " design principle, by the face of whole eyeglass Yu Corneal Contact
(inner surface) is designed as several segmental arc being mutually linked, and the special shape wearing rear lens inner surface is led
Cause to clip one layer of tear pockety between eyeglass and outer corneal surface, the hydrodynamics effect of tear
The epithelial cell of Central corneal should be drawn to middle perimembranous (peripheral)；Meanwhile, during eye closing, the work of eyelid
With making eyeglass central authorities, inferior cornea is imposed certain pressure.Both effects cause Central corneal bent
Rate flattens, and cornea shape tends to the shape in Ortho-K inner surface base curve district, and after plucking mirror, human eye is bent
Light state changes, and moves near retina direction depending on thing imaging point, myopia correction.
" reversion geometry " design of Ortho-K was proposed (US by Stoyan in 1989
4952045), Ortho-K is divided into three Ge Hu districts by initial reversion geometry designs, including base curve district,
Reversion arc district and circumference arc district, owing to the reversion arc district of this design is the widest, edge tilts the biggest,
Easily cause the random movement of eyeglass, there is bigger limitation clinically.
Reversion geometric areas is improved, typically by the Ortho-K that modern " reversion geometry " designs
It is divided into four regions.As shown in Figure 2, base curve district 11 contacts cornea middle section, and face shape is more
Smooth, it is used for flattening anterior corneal surface；Reversion arc district 12 is the most precipitous, is used for consolidating base curve district 11
Pressing effect, and ensure certain tear storage capacity；Pei Shihu district is named again in arc district 13, location, main
Stabilized lenses to be used for；Circumference arc district 14 ensures the circulation of cornea and Ortho-K periphery tear.
The inner surface of Ortho-K is moulding functional realiey region, and most design is for this district
Territory is carried out, and method is the radius of curvature for four Ge Hu districts and two variablees of width, according to patient's cornea
Shape and dioptric requirement are designed respectively.
At present, the design being widely used in producing typically uses 4-7 or 5-7 different curvature radius
Circular arc dovetail form.As shown in Figure 2, four arc districts are most basic designs, and four Ge Hu districts use
The sphere of four different radius of curvature, in Ge Hu district, joining place carries out chamfering, makes each segmental arc naturally hold in the mouth
Connect.5-7 circular arc dovetail refers at the multiple circular arcs in reversion arc district 12 and arc district 13, location (as instead
Zhuan Hu district uses two circular arcs, arc district, location to use three circular arcs) so that base curve district 11 and reversion arc
District 12 linking is easier to, and makes arc district, location 13 and cornea shape more agree with (owing to cornea is aspheric
Face, uses multiple sphere to carry out the form of fitting aspherical).Existing design also has employing aspheric surface
The design of location arc.
Due to the activity of keratocyte, the change of the cornea shape that Ortho-K brings is the most temporarily
, after stopping wearing Ortho-K, cornea can return to original form, and the most initial cornea is moulding
Mirror is only considered a kind for the treatment of means for temporary transient myopia correction.But follow-up clinical research for many years
Find, wear Ortho-K and a part of teenager axis oculi growth rate can be made to slow down, and then to myopia
Control action is played in development, and clinical research is pointed to, and wears Ortho-K descendant's eye-shaped and becomes myopiaization
Periphery out of focus is the mechanism that Ortho-K works.
The cornea of normal eye is usually aspheric surface, and periphery is more smooth than center, after cornea is moulding, and angle
Film front surface becomes sphere, i.e. the shape of Ortho-K rear surface.Fig. 3 is same curvature radius
The refractive power (as shown in B in figure) of sphere cornea (as shown in A in figure) and aspheric cornea is with hole
The schematic diagram of footpath change, it is seen then that sphere cornea, compared with aspheric cornea, can be that people's sideband near the eyes comes
Bigger refractive power.Therefore, the real mechanism that Ortho-K control myopia increases is to pass through night
Wear eyeglass, Ortho-K cornea has been fashioned into sphere (Ortho-K light school district inner surface
Shape) so that human eye refractive power of periphery when regarding thing is bigger than before moulding, make part wearer
Form myopiaization periphery out of focus, and then slow down axis oculi growth, control myopia progression.
Existing Ortho-K base curve district is sphere, and anterior surface of cornea can be moulded by the base curve district of sphere
Making as sphere, the power profile making cornea provide meets spheroid character, and it is not disadvantageously, for
For patient, amphiblestroid degree of crook is different, and existing Ortho-K is by cornea
Outer surface is modelled as the spherical shape in its base curve district, and its power profile only observes the refractive power of this sphere
The regularity of distribution, i.e. for identical moulding rear anterior surface of cornea radius of curvature, its power profile
Only a kind of form.Such as, being the cornea of 42.25D for moulding rear corneal curvature radius, it is bent
Luminous power distribution can only be a kind of situation as shown in A in Fig. 3, when the flexibility of human eye retina is more than
During the power profile flexibility that the cornea of diagram is formed, will be unable to form Myopia periphery out of focus, enter
And cannot play and control the purpose that myopia increases.Therefore, base curve is that the Ortho-K of sphere cannot shape
One-tenth degree controlled, effective peripheral refraction power control, be therefore only capable of making some patients be benefited control near
Depending on increasing, and the effective control making every patient all realize myopia cannot be accomplished.
Existing Ortho-K also has some to use aspheric design, if Berke is at US
In 7984988B2, the base curve district of Ortho-K is designed as ellipsoid；Sami G.EI Hage
US 5695509 advises, according to cornea shape and tear thickness, determine key coordinate point, with seat
Punctuate carries out aspheric surface matching, determines Ortho-K inner surface face shape；Patent 201420052256.2
It is aspheric surface by the front surface design of Ortho-K, for making human eye wear rear night from spherical aberration
Interference, improves visual quality.The target of these designs is all to enable cornea to reach at moulding rear human eye
More excellent visual quality, makes the distribution of full eye ametropia force keep consistent in each aperture as far as possible, and then leads
Causing the periphery out of focus of hypermetropia, this controls near-sighted purpose with periphery out of focus and method all runs in the opposite direction
's.
It is accordingly required in particular to a kind of base curve district is special aspheric Ortho-K, it is achieved degree can
The myopiaization periphery out of focus of control, with the problem solving above-mentioned existing existence.
