OrthoK instead of eye surgery?

Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. I'm looking at having eye surgery to correct my vision, as I'm tiring of wearing glasses; in particular with a deployment on the horizon.

    I am less skeptical about laser surgery now but still have my concerns. I have heard of Orthokeratology which consists of inserting shaped contact lenses into the eye at night, which gently compresses the cornea flat in line with your prescription needs. On removing them the wearer gets a day's worth of perfect vision without the hassle of a contact lens. Apparently the Chinese used to do this hundreds of years ago by sleeping with small bags of sand resting on their eyelids 8O

    Seems ideal. Any one heard of this before?
  2. Thanks for responding Deputy, but the Bates method is widely written-off as a myth. The Ortho-K does seem to have some physiological effects on the eyes, that seem to make more sense.

    My unaided eyesight is within army guidelines but looking to the future, I may wish to have a go at a more specialised role, and glasses would be a hinderence. I also don't like the idea of being in deserty places with my eyesight as it is (what's the Pashtu for - 'have you seen my glasses'?) :)
  3. Thanks for your comments. Have you found any benefits from the exercices in your opinion. I suppose that if your prescription doen't change there is an argument to suggest that the exercices have prevented a degeneration of the prescription which would be worth doing in it's own right. Does it minimise fatigue on the eyes or any other advantages in addition to improving eyesight?
  4. Thanks. Interestingly one of the techniques called 'palming' (can't imagine why my eyes were drawn to that one!) involves applying pressure on the eyeball using the palms of your hands. perhaps that pressure is recreating the effects of one of those ortho-k lenses which flatten the cornea? interesting anyway, cheers
  5. Cheree zma aynaki?
  6. I'd looked in to it a while back. Rather than "flattening / pressing" your cornea directly to alter your prescription the contact lenses redistribute the thin layer of epithelial cells that cover your cornea.

    As with refractive surgery that typically involves displacing / removing etc this outer layer it does leave you more susceptible to "dry eyes" as it generally takes 3-6 months for the cells to regrow again, as well as the usual symptoms associated with surgery (ghosting, halos, blurred / double vision etc).

    Bigger risk of infection, & corneal scarring / ulceration compared to surgery as well as you're handling the contacts daily & complacency may set in with hygiene, especially if you're living in less than ideal conditions for hygiene.
  7. Thanks Jock, I'll bare that in mind.
  8. removed because the mong left.

    I would recommend moving to daily contact lenses, with your glasses as back up. Other types will exacerbate dry eyes (monthlies definately), and with others you have the severe hygiene issue to contend with. Dailies mean a fresh new pair every day (funny that) so less of a hygiene issue. My brother used them in the 'stan whilst serving with 59RE, he had no issues.
  10. Nice one mate, thanks. Looking at laser really- could do with correcting my prescription permanently.
  11. I have only used monthlys, but do daily contacts feel the same as the monthly when worn for extensive period? Dry feeling, but watery and they seem to look dirty; This is usually after about...14 hours.
  12. I've just switched from monthly, to daily disposables. Not sure quite why, but the Daily's seem so much better.. I'm convinced that my sight is sharper with the Daily's compared to the monthly's, and I can wear them all day with no problems at all.
    I'm assuming they must be thinner than monthly's, so this must be why I'm seeing such a difference.
    Might be worth asking the optician for a trial run of daily's??
  13. If they do a trial I'll try that. Cheers
  14. If you have a lowish prescription, go to the right place, do everything right pre-op and post-op, have a surface treatment, then laser could be a good option.

    But you have to get all of that right, and you really want to avoid being exposed to lots of ultraviolet for a long time after, which could be hard to guarantee.
  15. External as in PKK? I understand they can do wavefront with that technique aswell, which should improve night vision issues I belive. Thanks
