At present, there is no exact and effective treatment for myopia in humans, but the market is still flooded with all kinds of physical therapy rooms, studios, treatment of myopia drugs 。。。。 I hope that parents can correctly understand, do not rush to the doctor, nowadays there are scientific research theoretical support only keratoplasty can effectively control myopia, post some related materials for your reference.
Orthokeratology (Ortho-K, commonly known as OK lenses) is a non-surgical reversible myopia treatment that changes the refractive state of the eye through the wearing of special hard contact lenses to temporarily reduce the degree of myopia.
After 3 months of non-surgical discontinuation, the cornea returns to its original state of safety, no complications, no age restrictions, and the possibility of controlling myopia or reducing the number of myopia lenses are easy to adapt (especially for nighttime wear).
Its mechanism of action.
mechanical compression of the hard lens, hydraulic effect of the tear fluid, massage during blinking, change of corneal morphological factors, microscopic: redistribution of corneal epithelial cells, change of corneal tissue morphology without physiological lesions
In fact, there are many misconceptions among both doctors and patients.
OK lenses can cure myopia
Any myopic eye is suitable
Vision is normalized from then on
You can stop wearing them after the age of 25
One lens is all you need
General opticians can do it
And there are many problems with the current national situation in China.
Poor awareness of myopia
The desire for myopia treatment
Unreasonable requirements for naked eye vision to join the army and go to school
The drive of money and interest
The country lacks the necessary correct management
To sum up, OK lenses should be correctly understood as
Myopia cannot be cured
The effect is temporary
It is effective but has limitations
Requires certain equipment and medical knowledge
Reasonable patient selection
Improved patient understanding
Standardized fitting
Importance of diagnostic lenses
Regular follow-up visits
Awareness-raising for fitters
The population for which OK lenses are indicated.
Good subjective motivation
No acute or chronic eye disease
Refractive error range: -0.5 to -4.0D
Astigmatism less than 1.5D, preferably paracritical
Corneal curvature R42D, Q46D
Corneal morphology from central to peripheral, gradually flattened
Normal pupil size
Conditions for which fitting is unsuitable include
Unrealistic belief that myopia can be cured
Ocular disorders such as infection, inflammation, other corneal conjunctival problems
Refractive error greater than -6.00, astigmatism greater than -2.00, retrocontrast astigmatism
Aged less than 12 years old
Poor compliance
Contraindications include
Acute or subacute infection or inflammation of the anterior segment of the eye
Any ocular disorder, injury or structural abnormality affecting the cornea, conjunctiva or eyelids.
Severe tear deficiency (dry eye)
Sluggish corneal perception
Any systemic or systematic disease that affects the eye or is aggravated by contact lens wear
Allergic reactions to the ocular surface or ocular appendages that may be triggered or aggravated by contact lens wear or the use of related care products
Possible allergy to any component of the care solution, such as thimerosal or chlorhexidine
Any active corneal infection (bacterial, fungal or viral)
Red eye or eye irritation
