Corneal remodelling contact lenses and methods of treating refractive error using corneal remodelling

摘要

Contact lenses are described with a corneal remodelling effect. This corneal remodelling effect is one or both of broad-area corneal remodelling and localised remodelling. The contact lenses may also have a refractive power. The refractive power may vary across the lens and for myopia may have increased power centrally. The increased power may be provided over a lens area that has increased thickness due to localised remodelling.

主权项

1. A contact lens for treating an eye with myopia, the contact lens having an optic zone comprising an area having a refractive first power, which corrects distance vision of the eye, and
comprising a structural profile to effect flattening remodelling of the cornea of the eye when the contact lens is fitted to the eye; wherein the contact lens comprises a central zone and an outer zone surrounding the central zone, wherein the central zone has an increased thickness relative to the outer zone, the increased thickness providing at least part of said structural profile to effect flattening remodelling of the cornea; and wherein the optic zone comprises a central optic zone, the central optic zone having a differential refractive power, which is positive relative to the first refractive power.
