Orthokeratology (Ortho-k)

Orthokeratology

Clear vision while you sleep.

Clear daytime vision without surgery, glasses or daytime contacts.

Orthokeratology (ortho-k) corrects your vision overnight with custom lenses, so you wake up seeing clearly.

How it works

Ortho-k uses custom gas permeable lenses worn overnight. They gently and temporarily reshape the front of the eye (the cornea) while you sleep. In the morning you take them out and see clearly through the day.

The effect is temporary: if you stop wearing the lenses, your eyes return to their original shape.

What it can correct

Nearsightedness (myopia), the most common use
In some cases, mild astigmatism or farsightedness
Often used for children to help manage myopia

Is it right for you?

Most people with mild to moderate myopia are good candidates, especially those who find glasses or daytime contacts inconvenient for sports, swimming or work. Your doctor will measure your eyes to confirm.

**An ortho-k lens on the eye**Fluorescein dye and blue light let us see how the lens sits on the cornea.

**The ortho-k bull’s-eye pattern**The dark center is where the lens gently flattens the cornea overnight, surrounded by a green ring of tear film.

**Checking ortho-k centration**We use these patterns to confirm the lens is centered so the overnight reshaping is even.

“The Beyond 2020 team are so amazing and helpful. Each and every employee is welcoming and professional. My husband and I were seen by Dr. Than, and she was such a delight. She addressed any questions we had and explained how we could fix it.”
