Orthokeratology, also known as Ortho-K are special lenses that can correct refractive errors, including nearsightedness, farsightedness, and astigmatism. If you are tired of relying on glasses or contacts to see correctly during the day, these contacts are a good option, and our optometrist at Main Street Vision Care can prescribe them.


What Is Orthokeratology?

These lenses differ from traditional lenses in that they are only worn at night. When you go to bed, you would put the contacts in your eyes. Refractive errors occur due to misshapen corneas. While you are sleeping, the lenses gently reshape your cornea. When you wake up and take them out, you will be able to see clearly.

How Long Do the Effects Last?

The effects of Ortho-K last all day. As long as you wear the contacts every night, your vision will be clear when you wake up. After two to three nights of not wearing the lenses, your vision will go back to the way that it was, and you will need glasses or contacts to see clearly.

How Long Before I See the Results Of Orthokeratology?

Most people no longer need their glasses after two nights of wearing these lenses. If you have a high prescription, it can take up to three nights before your vision is perfect.

Prescription Parameters for Ortho-K

To be a good candidate for Ortho-K, your prescription would need to fit within specific parameters. If you are nearsighted, your prescription can be no higher than -6.00. If you are farsighted, your prescription can be no higher than +2.00. Ortho-K can correct astigmatism up to 1.75 diopters.

Who Can Benefit From Orthokeratology?

Many people can benefit from wearing these lenses.

  • Children: This is an excellent option for children who have myopia. Studies have shown that it a very effective method in slowing the progression of this condition.
  • Water activities: If you are a swimmer, scuba diver, or if you enjoy any water sport, Ortho-K can be very beneficial. It is not recommended that you wear contacts in the water. Since these lenses are only worn at night, they are a good option.
  • Dry eye syndrome: Because Ortho-K lenses are worn at night, your eyes are closed the whole time; therefore, they won't dry out your eyes the way that traditional lenses can.
  • Poor candidate for Lasik: If you are a poor candidate for Lasik for any reason, Orthokeratology is an excellent alternative.
  • Presbyopia: If you have presbyopia, your optometrist can prescribe one lens for close-up and one lens for distance. This is called mono-vision. Your brain will automatically choose the appropriate eye for each task.
