Description
This application is that denomination of invention is the dividing an application of patent application in " a kind of physiological correcting contact lens " (application number 97103999.2, April 15 1997 applying date).
The present invention relates to medical health appliance, relate in particular to a kind of method of correction of refractive errors and realize the physiological correcting contact lens of the injection growth inducing thing of this method, be used for the treatment of the budding ametropia of teenager.
Ametropia comprises myopia, hypermetropia and astigmatism, in " ophthalmology dioptrics) " book of being published by military medicine Science Press May nineteen ninety-five detailed description is arranged.With regard to myopia, for the adult more than 25 years old, it is more effective that the cornea of at present popular former Soviet Union invention is put the excimer laser cornea method for grinding of blanking method and American's invention, but then powerless for being in the budding teenager below 25 years old.For the following less budding ametropia of treatment green grass or young crops, also do not find method both at home and abroad so far with definite curative effect.The disclosed Chinese patent of December in 1988 21 days (CN88205393A) has been introduced a kind of gazing type myopia preventing and treating device, its principle is that the position of same sighting target imaging in eye can take place traversing accordingly along with the difference of staring distance, user moves with regard to the scalable eye muscle repeatedly according to traversing size, thereby loosens adjusting.Other Therapeutic Method is medicament for the eyes water law, smoked Chinese medicine method, electrostimulation etc. a little, because these methods are not all touched the change of eyeball structure, so late result is relatively poor.
Just the someone found to exist potential difference between cornea and the retina as far back as 1894, cornea is positively charged, retina electronegative (seeing " neurophthalmology) " book of publishing by the People's Health Publisher in January, 1987 for details), although cornea does not have blood vessel simultaneously, but flexibility and plasticity are arranged, at these physiological characteristicies, general plotting of the present invention is to utilize contact lens to be carrier, characteristics such as plasticity with the period of development cornea are physiological foundation, utilize coaxial growth to induce the change that realizes corneal diopter and axiallength, correct ametropic purpose of teenager period of development thereby reach.
The objective of the invention is by on contact lens, injecting the growth inducing thing, change corneal curvature and axiallength with physiology or chemical action, thereby provide a kind of correcting contact lens of inducing the antidote of eyeball structure growth change and realizing this method for treating ametropia.
A kind of method of correction of refractive errors, it is characterized in that utilizing correcting contact lens to be carrier, characteristics such as plasticity with teenager period of development cornea are physiological foundation, by in contact lens, injecting the growth inducing thing, utilize growth inducing thing and cornea and all around contact surface have an effect, induce it to grow difference, realize the change of corneal diopter and axiallength, correct ametropic effect of teenager period of development thereby reach.
A kind of correcting contact lens, it is characterized in that being provided with physiological correcting plate 5 in the top of the base material 1 of existing common contact lens (contact lens), base material 1 is made by the contact lens,soft material, is provided with at least one group and makes the isolated mutually barrier layer 6 of growth inducing thing 4 on base material 1 and physiological correcting plate 5.Be the center of circle with the axis oculi center on the physiological correcting plate 5, be provided with the concentric ring of different-diameter, core 19 is equipped with different growth inducing things respectively with part 20 all around.When correcting contact lens is worn on the eyeball, promote cornea grow and suppress different growth-gens 4 that cornea grows along base material 1 micropore respectively with CC and all around contact surface have an effect, for the myope, make the CC depression, for the farsighted person, the position of conversion growth inducing thing 4 makes CC outstanding, thereby reaches the purpose of correction of refractive errors.
The present invention compares with existing treatment ametropia product and has the following advantages:
Treat ametropic basic outlet and be to change eyeball structure, if eyeball structure is changed, no matter how be, always can not break through the boundary of treatment pseudomyopia, and pseudomyopia does not belong to near-sighted category in essence, is the 2%-3% that only accounts for myopia from saying clinically yet, and all myopia prevention products are all only effective to pseudomyopia, so in treatment myopia, have little significance, and late result stability is also very poor.The present invention constantly changes, constantly grows under this hard situation at the teenager eyeball structure, by the effect of growth stimulator choice of location, this causes two big factors of eye refraction degree significant change to have changed corneal curvature and axiallength effectively, thereby has corrected refractive status effectively.Owing to, fundamentally solved ametropic problem under new condition along with teenager growth eyeball structure is finalized the design.
In addition, because the interaction of growth inducing thing and cornea is the physiology guiding, whole therapeutic process is safe and reliable, and life-time service is without any side effects.
The present invention has following accompanying drawing:
Figure 1A faces structural representation with the contact lens that the physiological correcting plate is made
The contact lens plan structure sketch map that Figure 1B makes with the physiological correcting plate
The contact lens structural representation of the external physiology guiding of Fig. 2 medicated cap
