This technology is a method of vision correction that employs an ultrafast laser pulse to alter corneal refractive properties without requiring additional tissue manipulation or injury.
The population of nearsighted people is expected to continue growing to 2.5 billion by 2020 and 4.5 billion by 2050. However, despite the availability of refractive surgery such as LASIK, few people are electing to have the procedure; current refractive surgeries have lengthy recovery times or are associated with new visual symptoms. As such, there is a need for a non-invasive vision correction procedure that can treat nearsightedness with reduced recovery time and fewer side effects.
This technology is a method of correcting the refractive properties of the cornea by employing an ultrafast femtosecond laser. The input light energy ionizes water molecules within the cornea, generating reactive oxygen species that cross-link collagen and altering its refractive index. This method avoids tissue damage by removing the need to manipulate the epithelial layer or photosensitizers.
This technology has been validated in rabbit eyes and was shown to be a safe and effective method with no adverse effects observed on the cellular matrix.
