Orthokeratology (also known as ortho-k or corneal reshaping therapy) is a non-surgical method of correcting refractive errors such as nearsightedness, farsightedness, and astigmatism. It involves the use of specially designed gas-permeable contact lenses that are worn overnight to temporarily reshape the cornea and improve vision during the day without the need for glasses or contact lenses. Orthokeratology has gained popularity in recent years as an alternative to LASIK surgery, especially for those who are not good candidates for surgery or prefer a non-invasive approach.

Orthokeratology works by applying gentle pressure on the cornea while you sleep, which causes it to reshape gradually over time. The lens design is tailored to each individual's eye shape, and the treatment is customized to correct their specific refractive error. The cornea is the clear, dome-shaped front surface of the eye, and its shape plays a crucial role in focusing light on the retina at the back of the eye. When the cornea is too steep or too flat, it can cause refractive errors that lead to blurred vision.
