Ortho-K lenses are a bit like braces for teeth. They are hard contact lenses that are worn while sleeping to flatten the front of the eye. As the eye is flattened, it corrects your prescription whilst you are sleeping. This allows better vision during the day without the need for contact lenses or glasses.
Our Optometrist will design a contact lens based on special maps of your eye. These contact lenses will allow changes to occur at night whilst you sleep so you can achieve clear and focused vision during the day.
When the lens is removed in the morning the cornea begins to return to its original shape but so slowly that good vision is maintained all waking hours. Each night the process is repeated athough some find they only need to wear their molds every other night. The elastic tissue of the eye is not harmed by this daily process.
Ortho K is reversible. It is not a permanent alteration of eye tissue and thus is an excellent Laser surgery alternative for those reluctant or unable to undergo a surgical alteration of their corneas.
