发明名称 Contact lens for reshaping the altered corneas of post refractive surgery, previous ortho-K or keratoconus
摘要 A contact lens is fitted to a cornea of a patient's eye to gradually alter the patient's cornea during continued wear to reshape the altered cornea conditions such as the corneas of post refractive surgery, post previous Ortho-K. and keratoconus. The contact lens has a plurality of zones that comprise one optical zone, at least one conformation zone, a connecting zones complex, an alignment zone and a peripheral zone. The one or more conformation zones are utilized to conform the angle of the central optical zone, as well as the alignment zone, to compress on the central and mid-peripheral portion of the altered cornea for redistribute cornea tissue to reduce the residual refractive errors, after refractive surgery, or to smooth out the central cornea surface of the keratoconus for better bare or spectacle vision after contact lens are removed.
