Corneal Refractive Therapy

CRT is an option that allows patients to wear contact lenses at night and see without wearing either glasses or contacts during the day. The lenses used for CRT are high water content high oxygen permeability rigid lenses. The CRT lenses actually shape the surface of the cornea during sleep. This re-shaping is temporary, but after a few nights of wearing the lenses daytime vision will improve. CRT is especially beneficial to children with rapidly increasing myopia and can slow down the progression and limit the severity of myopia over time. CRT is limited to a range of prescriptions; see one of our doctors for more information.
