At North York Eye Clinic, the doctors offer orthokeratology lenses. Orthokeratology (also known as Ortho-K or corneal reshaping therapy) lenses are specialized contact lenses that are designed to temporarily change the shape of the cornea, the clear front surface of the eye.
These lenses are rigid hard contact lenses that are worn overnight while you sleep, and they gently reshape the cornea to correct myopia (nearsightedness) and sometimes mild astigmatism. In the morning, the lenses are removed, and the cornea retains the new shape, providing clear vision throughout the day.
Ortho-K lenses are made of a rigid gas permeable material, which allows oxygen to reach the cornea. They are custom-fit for each individual based on the shape of their cornea, and they can take a few weeks and a few different custom-made lenses to achieve maximum effectiveness.
Ortho-K lenses are typically used by people who want an alternative to traditional glasses or contact lenses, and who do not want to undergo surgery such as LASIK. They can also be a good option for people who participate in sports or other activities where glasses or contacts may be inconvenient or uncomfortable.
Some advantages of Ortho-K lenses include:
However, it's important to note that Ortho-K lenses may not be suitable for everyone, and they require regular check-ups with an eye care professional to ensure their safety and effectiveness.
