Abstract
A method of correcting refractive error in an eye, comprising the steps of marking at least one axis on the surface of the cornea. A portion of the cornea is then separated, forming a first anterior facing surface and a second posterior facing surface. An inlay having at least one axis indicated on the surface thereof is positioned between the first and second surfaces, and the at least one axis on the inlay is aligned with the at least one axis on the surface of the cornea. This results in precise positioning and orientation of the inlay and thus correction of astigmatic error in the cornea.
Claims23
An inlay for correcting the refractive error in the cornea of the eye, the cornea having a first exposed corneal surface and a second corneal surface, the inlay, comprising:
- a first surface for placement onto the first exposed corneal surface,
- a second surface opposite the first surface, and
- a removable, pliable sheet of material positioned directly adjacent the second surface, said sheet overlying and conforming to the second surface and having markings thereon for accurately positioning the inlay on the first exposed corneal surface.
An inlay for correcting refractive error in the cornea of the eye, the cornea having a first exposed corneal surface and a second corneal surface, the inlay, comprising:
- a first surface and a second surface, at least one of said first and second surfaces having at least one removable marking thereon being extendable along at least one radial axis thereof, said at least one marking being adapted to align with a corresponding marking on at least one of the first and second corneal surfaces;
- and
- said at least one removable marking being disposed on a removable sheet of material directly overlying the second surface.
An inlay for correcting the refractive error in the cornea of the eye, the cornea having a first exposed corneal surface and a second corneal surface, the inlay, comprising:
- a first surface for placement onto the first exposed corneal surface,
- a second surface opposite the first surface, and
- a removable, transparent, pliable sheet of material positioned directly adjacent overlying the second surface, said sheet overlying and conforming to the second surface and having markings thereon for accurately positioning the inlay on the first exposed corneal surface.
