Re: Orthokeratology - Eye correction
I'm told that using them for years isn't supposed to give any problems. The inside front of the contact has a flat plateau corresponding to what you need for correcting. The inside front of the lens doesn't actually touch the cornea. It uses tears or saline solution to reshape the cornea. I fill the lens up with saline solution and put the contacts on with my head pointing down; if I don't an air bubble will get trapped in the contact. With the contact filled up with liquid and then put on, air won't get caught under that front part of the lens.
They are a larger diameter than an rgp lens but smaller than soft contacts. You can see well while they are in your eyes and feel similar to rgp lenses.
