Orthokeratology, a non-surgical procedure, can effectively correct vision in children.
Night orthokeratological lenses are used to restore vision by gently altering the cornea’s shape while you sleep. This means you can ditch your reading lenses and contact lenses for good!
Myopia, hyperopia, and even astigmatism are all treatable with OK therapy.
The ophthalmologist is the one who ultimately decides whether or not to schedule OK therapy. Qualified optician optometrist uses eye examination results to recommend orthokeratological lenses.
I was wondering if it was secure.
If all of an ophthalmologist’s instructions are followed, orthokeratology is completely risk-free. There is still a film of tears between the lens and the eye, so there is no direct contact. In orthokeratology, the lens is designed to correct corneal shape changes caused by the pressure of tears. In addition, after some time has passed, the patient is at ease and reports no unusual sensations.
What is the function of an orthokeratology lens?
When applied to the eye, ortholens smooth the cornea. The shape of the corneal epithelium alters when wearing night lenses. This improves the patient’s ability to see clearly without the aid of corrective lenses like lenses or contacts, thus increasing visual acuity.
It takes 12 to 48 hours for the effects of orthokeratology lenses to wear off. If you ever decide to stop wearing contact lenses, the cornea will heal itself in a matter of days because only the epithelium, the outermost layer of the cornea, is affected.
The lenses have a negligible effect, are completely painless, and pose no threat to the wearer’s eyes.
Lenses designed for use in pediatric orthokeratology
Progressive myopia in children is a condition that can be treated with orthokeratology. Therapeutically effective night lenses can halt or significantly slow the progression of myopia.
False myopia can also be treated with OK therapy; corrective lenses can eliminate the condition entirely and stop it from progressing to true myopia.
Once a child reaches the age of 7, they are permitted to start wearing nighttime contact lenses. During the study, when the visual load increases by a factor of several, it is essential to “support” vision. Myopia can progress rapidly in such situations. Preventative measures can be taken with orthokeratology.
Orthokeratology, specifically its efficacy and method of treatment,
Although orthokeratology is not effective for treating vision impairment, using night lenses can improve visibility for a short time, typically a day. Myopia progression in children can be slowed by using ortholenses.
The lenses must be worn consistently, each night, to produce a stable and high-quality result initially. Contact lenses should be worn for 7-10 hours at a time. Because the human eye is remarkably adaptable, the duration of the effect will lengthen as time progresses.
About 5 percent of people receiving Ortho-K treatment don’t respond fully. This is because older patients have a harder time adjusting to orthokeratology due to their age and the unique characteristics of their eyes and genes.
Exactly how successful is the change?
Lenses require a one-month adaptation period, on average. The patient sees an ophthalmologist at regular intervals during the adaptation phase so that the doctor can assess the impact of the lenses and keep an eye on the health of the eyes.
