It's not my new procedure. I don't own it.
Risks...hmm. Well, there's no surgery involved. And if you stop wearing the lenses, your eyes go back to normal. A brief google (feel free to do a more in-depth one) came up with these:
Infection ? an unlikely event and no greater than with your other contact lenses. Your risk to infection is proportional to your hygiene.
Irregular Astigmatism ? extremely rare and completely reversible.
Overcorrection/Undercorrection ? all treatments can be modified or reversed.
Regression ? you may lose some effect by the end of the day during the first few days. After that, the effect will last all waking hours for as long as you wear the lens as prescribed.
Light Sensitivity ? may occur during the first few days of treatment.
Contact Lens Intolerance ? not usually a problem since you wear the lens with your eyes closed.
Halos/Glare ? transitory. More likely to be seen with light coloured eyes with large pupils at night. The effect is completely reversible.
Reduced Contrast Sensitivity ? a rarely reported reduced ability to discern between ?shades of gray?. The effect is completely reversible.
And also this (my bold):
What is Orthokeratology?
Ortho-K is a procedure which uses oxygen permeable contact lenses to produce a reduction in myopia by redistributing the surface cells of your eye while you sleep. Much like braces reposition your teeth, this redistribution of cells is accomplished by using hydraulic forces under the contact lens. The contact lens does not apply direct pressure to your eye. It is a safe, non-surgical, reversible, modifiable alternative to laser eye surgery and does not require medications.
How does Orthokeratolgy work?
The front surface of an eye is called the cornea. The cornea is like a watch crystal in that it is transparent and very strong. The cornea is about ½ mm (500 microns) thick, has five layers and is mostly made of water. The corneal curvature is responsible for about 60% of the light bending (refractive) power of your eye. As the Ortho-K lens is worn while you sleep at night, up to 15 microns of surface cells are precisely redistributed to create a small change in corneal curvature which results in a large change in the focusing of light inside the eye. Laser surgery permanently vaporizes about 40 microns of corneal tissue for the same amount of correction.
Who is a good candidate for Ortho-K?
Good candidates for Ortho-K are persons with healthy eyes and no prior history of significant ocular disease or injury.
Still think I'm off topic?! Or is this indeed 'an improved one'?!
