Orthokeratology

 'Ortho' is derived from the Latin word meaning 'straight' and then Keratology is the science of altering the shape of the cornea that's the clear front window surface to the eye.

Ortho K contact lenses is just a way of using a contact lens to mold or sculpt the front surface of the eye so that you can see better now.

A French ophthalmologist of the name Eugene Kurt who noted that when he fit his patients with glass contact lenses and it pushed on the eye they could see better afterwards.

Ortho K Lens

These types of contact lenses are custom made and specifically designed to be worn while you sleep. While you wear your contact lens it shapes and molds the surface of your eye and the next morning when you take it off then you see clearly throughout the day.

The reason of all this working is the front part of the cornea has cells called the epithelium  it's about 50 microns thick ans this contact lens will push on that central epithelium and basically squeeze the fluid from the centre of the cornea out to farther edges and that kind of makes a plateau shape and that makes the light that's entering your eye focus more correctly onto the retina in the back of the eye giving you better vision. 

The catch to all this is that the central cornea does reform and kind of spring back to its original shape which requires you to wear these types of ortho k lenses at night time every single night in fact it takes about one to two weeks of wearing them every night just to get the eye to be about the shape that it needs to be in order to see your very best. 

Then you also need to keep wearing the lenses every night otherwise if you don't the surface of the eye will kind of regress back to its original shape and you won't see as clearly again. It basically just goes back to what your vision was like before you started wearing these type of contacts.

So who makes a good candidate for ortho k lenses?

Anybody who doesn't really like to wear glasses or contact lenses throughout the day maybe an athlete. 

How Orthokeratology Works?

Corneal molding is a non-surgical treatment option for people suffering from mild to moderate nearsightedness or astigmatism.

Corneal molding offers a legitimate alternative to laser vision correction for many people. 

1. This procedure uses specially designed contact lenses which are prescribed to reshape the surface of the cornea and reduce or eliminate the need for glasses or regular contact lenses.
2. Corneal molding treatment involves changing the curvature of the cornea by temporarily molding its shape using a gas permeable contact lens.
3. The central portion of the lens fits closer to the eye than a standard contact lens exerting a gentle pressure. 
4. The outer part of the lens surrounds the central visual zone and is farther away from the cornea allowing room for the cornea to change shape.
5. By changing the curvature of your cornea this treatment refocuses livht onto your retina resulting in clearer vision.
6. Corneal moldinh is completely is completely reversible and non-invasive. If you stop wearing the molds your cornea will return to its original shape.
7. In the past the only FDA approved corneal molding systems were worn during the day and proved to be very safe and effective. Recently the FDA has approved the latest in corneal molding technology with an overnight lens that works for the eyes.
