Ortho-K is Cutting-Edge, Non-Surgical Vision Correction
Are you frustrated with wearing contacts or glasses but not a good candidate for LASIK surgery or PRK surgery? If so, you may be a good candidate for an advanced corneal reshaping technique known as orthokeratology, or Ortho-K. This non-surgical technique changes the way your cornea refracts light, correcting common vision problems including nearsightedness, farsightedness and astigmatism. By wearing specially design glass permeable corneal retainers at night while you sleep, these retainers will gently reshape your cornea to correct for refractive errors. You can see clearly for one or two days after wearing Ortho-K corneal retainers at night; for best results, you will need to wear these retainers every night.
Ortho-K Reshapes Cornea While You Sleep
The cornea is a transparent, spherical bulge covering the lens of your eye. In addition to protecting the inner parts of the eye, the cornea also refracts incoming light on the lens so the light can be focused into a clear, sharp image before it passes onto the retina and, ultimately, the optic nerve. A deformation in the cornea can affect the cornea’s ability correctly refract light onto the lens of your eye, causing refractive errors including nearsightedness, farsightedness, and astigmatism.
While LASIK eye surgery is a popular choice for permanent vision correction, not every patient is a good candidate for this procedure. For example, if you have thin corneas, untreated cataracts, diabetes, certain autoimmune diseases or the corneal disease keratoconus, our optometrist may not consider you a suitable candidate for LASIK. Additionally, other individuals are simply not comfortable with the idea of a laser permanently altering the shape of their cornea. If you are not a good candidate for LASIK or you are not comfortable with laser surgery, then you may wish to consider Ortho-K as a treatment alternative. Since Ortho-K is not a permanent treatment option, you will need to continue wearing the corneal retainers each night in order to continue receiving benefits from the treatment.
Ortho-K uses corneal retainers to reshape your corneas while you sleep. Unlike contacts, you will wear Ortho-K corneal retainers at night while you sleep. Upon waking, remove the retainers and enjoy perfect or near-perfect vision for the day. Ortho-K is not a permanent solution to cornea deformation. Ortho-K results last for one or two days; as long as you wear Ortho-K retainers at night while sleeping, you will continue to enjoy the vision benefits. You can stop wearing the retainers at any time and your corneas will resume their previous shape after several days.
Ortho-K is most commonly used to correct nearsightedness upwards of -6.00 diopters. Ortho-K can also correct lesser degrees of astigmatism (blurred vision at all distances), hyperopia (farsightedness) and presbyopia (blurred near vision associated with aging). All these common vision problems are caused by refractive errors. For example, a slight imperfection in the curvature of the cornea (one direction curves differently than another) can cause astigmatism. Ortho-K can correct this.
