Orthokeratology (Ortho-K) is a non-surgical procedure using specially designed contact lenses to gently reshape the eye to correct vision. The custom contacts are worn during sleep and removed in the morning, providing clear vision during the day. This eliminates the need for glasses and contacts.
Ortho-K is most commonly used to correct myopia (nearsightedness), but can also correct hyperopia, astigmatism and presbyopia. This is also a good option for current soft contact lens wearers who have discomfort with their contacts due to allergy, dry eyes or dusty work environment. Many people who are active in sports or other activities love the freedom from glasses, contact lenses and sports goggles.
One big advantage is that Ortho-K has been shown to slow myopia progression in children and teenagers. Between the ages of 8 and 15, myopia can increase rapidly. This increase in nearsightedness increases the risk of sight-threatening conditions such as retinal detachments, cataracts and glaucoma. Studies show that using Ortho-K can dramatically slow down progression of myopia and even arrest it in certain patients.
When first starting Ortho-K, vision will dramatically improve after one night of wear. It can take up to a couple weeks of wearing the lenses to get to the full correction. We will see you for follow-up visits during this process. Once stable, most people need to wear the contact lenses nightly to retain the benefits. The doctor can determine if you are a good candidate for Ortho-K with a thorough eye exam.
We use Paragon CRT (Corneal Refractive Therapy) lenses, which are a type of Ortho-K.
