Optometrist's Frequently Asked Questions about Ortho-K
Q: Please explain what Ortho-Keratology is and give a basic sense of how it works.
A: Orthokeratology is a procedure using specially designed gas permeable contact lenses to gently reshape the corneal curvature of the eye while sleeping. The lenses are designed to be removed upon awakening and the patient will have great vision throughout the day without the need of daily contact lenses or eyeglasses.
Q: When will the ortho-k lenses start working?
A: After one or two nights of wearing the lenses, you will notice that your vision has improved. It could take a bit longer to reach perfect vision. Most people report achieving clear and sharp vision within two weeks. FDA trials have shown that approximately 65% of all patients who use CRT achieve 20/20 visual acuity.
Q: Can I wear my contact lenses while I sleep?
A: It’s always better NOT to wear your contact lenses while sleeping. Complications and infections in contact lens wearers multiplies 3-5 fold when worn during sleeping/extended wear. Many of these infections and complications can be very painful, they require discontinued use of the contacts during treatment that may last up to a few months, and can even lead to permanent vision loss.
Q: What are the latest trends in contact lenses?
A: Many contact lens manufacturers are now producing “daily” disposable contact lenses. These are lenses that are inserted in the morning and thrown away at night. This style of contact lens wear is both convenient and healthy. With these lenses, patients buy less solutions and don’t have to keep up with how old their lenses are and when to change them. Daily disposables are also beneficial in causing less allergy and dryness while reducing the risks of infection. Daily lenses are now offered in all types of prescriptions from distance vision to astigmatism and multifocal/bifocal prescriptions.
