What is Orthokeratology?
Orthokeratology (Ortho-K) is a procedure designed to effect the reduction of refractive anomalies by programmed application of rigid contact lenses.
Orthokeratology was born in the 1960’s when optometrists discovered that patients who wore hard contact lenses frequently demonstrated a reduction of their nearsightedness. The technique progressed in the 1980’s with the development of improved manufacturing techniques, which allowed more complex designs which to that time had been impossible to manufacture.
The best analogy for Orthokeratology is “orthodontics for the eye.” The corneal shape is altered by the gentle pressure from specially designed lenses. When the force is removed the cornea “remembers” the shape, but slowly returns to the original parameters. currently, it is not possible to exactly predict the responsiveness of an individual’s cornea to the molding forces of Orthokeratology
What is the treatment process?
The first state of treatment is a full general examination. This is required to measure the correction needs, corneal topography as well as assess the health of the eyes.
Once the initial lens is designed, the patient will be instructed in the care and handling of the lenses. You will be given EXACT wearing instructions.
Generally, you will be seen the day after the lenses are dispensed. At that visit, the corneal health, vision and corneal shape will be evaluated. Careful monitoring continues throughout the therapy.
Most patients achieve significant results in the first week. Once maximum results are attained retainer wear is initiated. That is, we determine the minimum wear necessary to maintain the correction change.
Not all patients will reach maximum improvement. A certain portion will fail early on and others will drop out later. Fortunately, this number is comparatively small.
What are the risks?
Many of the risks associated with Orthokeratology are the same as those for traditional contact lenses. Because the patient is monitored very closely these risks are minimized.
While careful monitoring keeps the risks to an absolute minimum, the patient plays a major role: good hygiene while handling lenses; following lens care instructions and not cutting corners is essential. Keeping scheduled appointments will allow the early detection of many potential problems.
What are the advantages?
Imagine waking in the middle of the night and being able to see clearer. Or being able to swim or play sports without the fear of losing a lens.
Your chosen occupation may require good unaided vision. Or your work environment may not be conducive to contact lenses or glasses.
Ongoing costs of lens care are reduced significantly.
