Keraflex Prozedur zur Keratokonusbehandlung und zur Korrektur von FehlsichtigkeitenKeraflex is Avedro's (a U.S. based company) patented and proprietary, non-invasive refractive correction procedure that gently reshapes the cornea. Because it is non-incisional and non-invasive, Avedro believes Keraflex will be the first refractive correction procedure to preserve the cornea’s bio-mechanical integrity. Keraflex is expected to overcome current barriers to the broader adoption of laser vision correction, especially fear of undergoing eye surgery among low and moderate myopes. Refractive correction and the preservation of the biomechanical integrity of the cornea are also proving to be of importance in the treatment of keratoconus.
During a Keraflex® procedure, the Vedera™ KXS delivers a single low energy microwave pulse lasting less than one second. Energy is applied to the cornea using a dielectrically shielded microwave emitter which contacts the epithelial surface. Through capacitive coupling, the single pulse raises the temperature of the selected region of corneal stroma to approximately 65°C, shrinking the collagen and forming a toroidal lesion in the upper 150 microns of the stroma.
Using an evaporative cooling technique (patent pending), the Vedera KXS cools the surface of the cornea during the treatment to isolate and protect Bowman’s membrane from the thermal effects of the microwave energy. The lesion created during Keraflex is intended to flatten the central cornea to achieve myopic correction without compromising the biomechanical integrity of the cornea.
The amount of induced refractive change achievable with the Vedera KXS is a function of lesion diameter and cross-section. Avedro has developed Keraflex Applicators with varying diameter emitters to provide the capability to create a range of lesion diameters when performing the Keraflex procedure. Depending on the amount of energy delivered by the Vedera KXS and the choice of Keraflex Applicator, tissue lesions of differing dimensions and geometries can be created.
