Corneal refractive therapy is a method of vision correction that eliminates the need to wear eyeglasses or use contact lenses during the day. The procedure, which is also known as overnight vision correction or corneal reshaping, involves the use of specially designed rigid gas-permeable contact lenses to gently reshape the cornea. Placed at bedtime and removed in the morning, these lenses precisely mold the front surface of the eye so that clear, crisp vision can be enjoyed throughout the day.
Vision markedly improves as the reshaped cornea correctly focuses light on the retina to produce clearer images. While some people experience significant improvements in vision after just a night or two of wearing the lenses, more time may be needed for complete vision correction in cases involving larger refractive errors.
Besides being non-invasive and suitable for patients of all ages, the treatment is completely reversible. This means that it can be discontinued at any time without any permanent changes to your eyes; thereby leaving you free to once again explore wearing eyeglasses, contact lenses during the day or having a LASIK procedure.
