During these last years, Ortho-K lenses, in addition to being permeable to gas and used at night, have shown that temporarily correct refractive errors.
En Área Oftalmológica Avanzada We explain what orthokeratology is and what are the vision defects that it helps to correct.
Definition of orthokeratology
La Orthokeratology is a specialty of contactology that is dedicated to the adaptation of Ortho-K lenses that consist of modeling the cornea at night so that during the day we can enjoy clear vision. Also are designed according to the needs of each patient .
How do the Ortho-K lenses? While the person sleeps, the lens acts by modeling the defects of the cornea so that, the next day, they can see correctly without the need to use glasses or contact lenses.
What vision defects is orthokeratology used for?
Orthokeratology offers Ortho-K lenses for two purposes:
- Correct refractive errors and farsightednessplatforms, astigmatism and mainly the myopia. In some cases, the ophthalmologist may consider using Ortho-K lenses for presbyopia.
- Orthokeratology is one of the best options for ccorrect the myopia during childhood y prevent a child from developing myopia very high in the adult stage.
Who is a good candidate for Ortho-K lenses?
The nearsighted children or young people who do not want to wear glasses, they can wear Ortho-K lenses until their eyeball is fully developed and then opt for a refractive surgery.
As we mentioned before, it is an excellent option for prevent children from developing high myopia and that can put your vision at risk during adulthood.
The use of orthokeratology is also recommended to people who play sports, who work in dusty environments or that cannot be operated due to some eye disease or patients with Dry eye syndrome.
What results are obtained?
Orthokeratology lenses allow corneal defects to be shaped temporarily.
Likewise, the correction of the refractive error can last up to three days, although ophthalmologists and contact specialists usually recommend the patient to wear night contact lenses every day.
Some experts in orthokeratology assure that 100% vision can be obtained, which is sufficient in any case for those patients interested in renewing their driving licence.
Differences with contact lenses
The main difference between conventional lenses and Ortho-K lenses is their mechanism of use and action.
While conventional lenses are made with the graduation that the patient has a certain refractive error, Ortho-K lenses are gas permeable lenses that have been designed to correct and flatten the patient's corneal defects.
Therefore, if the patient has used Ortho-K lenses for several hours, the cornea will have been shaped and the patient will be able to see correctly without the need to wear glasses or contact lenses.
