Orthokeratology (also known as Ortho-K, Overnight Vision Correction and Corneal Reshaping Therapy) is a non-surgical process that offers freedom from glasses and contact lenses during the day by reshaping the cornea overnight while you sleep. The result is the temporary correction of myopia (nearsightedness) or hyperopia (farsightedness), even if you have moderate astigmatism. Ortho-K therapeutic lenses are similar in appearance to standard contact lenses, and they gently reshape the corneal surface during sleep to provide clear, natural vision when the lenses are removed upon waking.
This leading-edge technology can enhance the lives of those requiring vision correction, especially if they are active individuals who play sports or participate in outdoor activities without the interference of glasses or contact lenses. Current soft contact lens wearers who are bothered by irritation and dryness due to dust and pollutants can also benefit from this treatment.
