We Fit Ortho-k Lenses in Fort Worth and Southlake

Orthokeratology, also known as ortho-k, Corneal Refractive Therapy (CRT), and Vision Shaping Treatment (VST), is a non-invasive method to correct vision with specialized contact lenses.

If you have nearsightedness (myopia), orthokeratology can provide crisp and clear vision without wearing any daytime eyewear or undergoing surgery. For many people who find eyeglasses and daytime contacts to be a nuisance, and LASIK is not an appropriate solution, ortho-k is a dream come true!

With ortho-k lenses, you can finally enjoy freedom from your eyeglasses or contact lenses throughout the day. Our eye doctors in Fort Worth and Southlake, TX, are experienced with fitting ortho-k lenses. Why wait any longer for clear and comfortable vision? Contact us to book your consultation.

Intro to Ortho-k

How does this method of vision correction work? You insert customized rigid gas permeable contact lenses before bedtime. As you doze through the night, your ortho-k lenses will gently reshape your cornea into a new shape.

The goal is to correct refractive error, thereby resolving myopia. When you wake up in the morning, you will remove the lenses and see clearly without putting on eyeglasses or other contacts. The effects of ortho-k lenses only last a few days before your vision returns to its original state, so you must re-insert these contacts on anightly basis.

Candidates for Ortho-k

Typically, if you have mild to moderate myopia and healthy eyes, ortho-k can be an effective and suitable option. Age does not matter; orthokeratology is regarded safe for children above five years old.

In general, the best results are experienced by people with a lens power less than -6.00 diopters and astigmatism less than -1.75 diopters.

According to FDA trials, over 65% of patients who qualified for and tried ortho-k achieved 20/20 visual acuity! To find out if you are a good candidate for ortho-k lenses, schedule an eye exam in our Fort Worth or Southlake, TX, eye care centers.

Safety & Side Effects of Ortho-k

When you first begin with orthokeratology, you may experience glare or see starbursts and halos around lights, especially when you are in a dark setting.

Yet, these possible side effects are temporary. Our Fort Worth and Southlake, TX, patients generally report that these symptoms only last for a few days after starting orthokeratology. As for comfort, ortho-k lenses are worn while sleeping and most people never even sense that they are there.

Paragon CRT Contact Lenses are safe for eye health and approved by the FDA for overnight orthokeratology. In sum, vision shaping is known to be a comfortable, safe, and painless process.

Orthokeratology and Myopia Control

Many studies have demonstrated how ortho-k lenses can suppress elongation and growth of the eye. In effect, this will slow or stop the progression of nearsightedness in children. If your child wears glasses or contacts and constantly requires a more powerful vision prescription after every yearly eye exam, ortho-k may be a recommended solution. Ask our eye doctors in Southlake and Fort Worth about ortho-k and myopia control for kids.
