Medical Forum / General / Vision / October 2005Ortho-K
Hello, since I'm hear I might as well mention that I saw Orthokeratology demonstrated on a tv show the other day. The presenter, who had worn glasses/contacts all his life had tried Ortho-k lenses and for the first time in his life could see without any assistance, after a while. . Basically for anyone unfamiliar with how it works, you wear the rigid lenses at night and they re-shape your cornea (using the pressure of the eyelid during sleep) to correct short-sightedness. It seems a great way of avoiding laser treatment. What do the posters in here think of this treatment?  SignatureJeffrey Spoon To me, it seems to be a lot of effort for very little reward. And the reward is TEMPORARY. It goes away when you stop the uncomfortable "treatment". forget it... w.stacy, o.d. > Hello, since I'm hear I might as well mention that I saw Orthokeratology > demonstrated on a tv show the other day.

Your points could equally be made about conventional contact lenses: a lot of effort for a temporary reward which goes away when you stop the treatment. However the reward in both cases is clear vision, quite a worthwhile reward I would have thought. Whether it's worth us optometrists buying a corneal topographer just so we can do it, I'm not so sure. From a business point of view, I have heard it said that it's one of the most profitable areas of optometry (I don't do it... but have an open mind...)

The effects are not permanent and will last for one to two days. Patients who have problems wearing contacts during the day, example eyes get dry, eyes that get slightly red with contact lens use although comfortable, Those working in dusty environments, Certain sports such as swimming, all find Ortho-K. a usefull alternative. The lenses are large (average 10.6mm) and according to feedback, more comfortable then RGP's. These lenses seem to have controlled the myopia of most of my patients wearing them and most of my fellow practitioners are reporting the same results. By the way, the lenses flatten the central cornea even when worn during the day as well. The pressure is due to the tears under the reverse geometry lens. This produces a negative pressure at the periphery of the lens, causing the cornea at this area to be SUCKED up thus steepening it. When this area steepens, the central area must flatten as a result. I guess you might say Ortho--K. sucks. Roland J. Izaac >I have been fitting Ortho-K. lenses for the past 5 years. The effects are >not permanent and will last for one to two days.

I used to wear RGP's myself, they're not too bad once get used to them. SignatureJeffrey Spoon |
