Orthokeratology Facts For Non Surgical Eye Sight Correction In Virginia City MT
Orthokeratology is a non-surgical treatment utilizing specially developed contact lenses to carefully reshape the curvature of your eyes to make you see better. Orthokeratology is also known by a few different names, the most common being ortho k, while some others consist of corneal refractive therapy, CRT, accelerated overnight orthokeratology and corneal reshaping therapy. In the most basic of terms Orthokeratology or Ortho K is the science of altering the curvature or shape of the clear front part of the eye, the cornea, to alter how light is concentrated on the retina at the back of your eyes.
This is a non-surgical procedure that eliminates the need for glasses or daytime contact lenses. It improves vision by carefully reshaping your eyes using specifically designed restorative contact lenses. The manner in which this works is that you just put specifically fitted contact lenses in at bedtime, and when you awake, you will have sharp natural vision for the rest of your waking hours.

Think about the cornea as the eye’s equivalent of a watch crystal. It is a clear, dome shaped structure that overlies the colored iris. Its tissue is most similar to clear, wet skin; and like skin it is really flexible. Because the cornea separates the eye from air and the rest of the outside world and since it has a curvature that flexes light to the back of the eye, it is accountable for the majority of the eye’s corrective power and adds to numerous conditions such as nearsightedness (myopia), farsightedness (hyperopia), and the blur of astigmatism.
When you select Ortho-k a few key tests must be performed. Chief amongst these tests is the determination that your eyes are healthy. Your orthokeratology doctor will more than likely be an Optometrist with specialized training in the area of corneal reshaping. He or she will analyze the retina as well as the health of the front part of the eye and the inside of the eye. The other essential procedural test is the mapping of your cornea. To do this an instrument called a corneal topographer is used. Much like a topographical map of the United States reveals mountains and valleys and subtle changes in elevation; the topography of the eye shows your doctor exactly how your cornea is shaped. The details from your corneal mapping plus the accurate measurement of the size of your cornea and the prescription needed to correct your vision are all utilized to create the retainer lenses (corneal molds) that are used to create the Ortho-k result.
On the day you get your Ortho-k retainer lenses you will be instructed in how to insert, remove, and properly take care of your vision retainers. The fit of your retainers will be evaluated and you will be set up to be seen after your first night of wear. On day 1, your doctor will re-evaluate your fit and newly corrected vision and another mapping of your cornea will be carried out.
Throughout your preliminary fitting period, your optometrist will monitor your corneal health and the progress of treatment. At specific times your retainer lens fit may be customized to achieve your objectives.

Orthokeratology can produce results in a surprisingly brief time period. The length of treatment to achieve your goals can differ from patient to person and will depend upon a number of elements including your prescription, the quantity and quality of your tear production, your expectations as well as something called corneal rigidity.
We advise patients that they may need to wear their retainers every night to maintain their recently fixed vision. Some people have the ability to reduce their wearing schedule so that they only need to use their lenses as little as every two to four nights. The reason for this is because of the flexibility or (rigidness) of your cornea.
