Abstract
Lenses and methods of lens attachment are disclosed which provide for highly effective, e.g., secure, attachment of the lens to the patient's cornea. Lenses are configured which are particularly adapted to be overlaid with corneal tissue to protect the lenses from forces parallel to the radial axis of the lens and generally parallel to the anterior surface of the lens optic.
Claims39
A lens device for attachment to a cornea, said lens device comprising:
- an optic having an optical axis;
- a flange coupled to the optic and extending radially outwardly of the optic;
- said flange including first and second radially extending projections adapted for use in attaching the lens device to the cornea, portions of said projections lying in the same axial plane and on the same side of the optical axis;
- and
- said first projection extending radially outwardly.
A lens device for attachment to a cornea, said lens device comprising:
- an optic having an optical axis;
- a flange coupled to the optic and extending radially outwardly of the optic;
- said flange including a radially inwardly extending projection adapted for use in attaching the lens device to the cornea;
- and
- the flange having a posterior surface and the radiallly inwardly projection and the posterior surface defining a V-shaped flute which opens radially inwardly.
A method for attaching a lens device to the cornea of an eye comprising:
- providing an optic having an optical axis and a flange coupled to the optic and extending radially outwardly of the optic with the flange including a radially inwardly extending projection which cooperates with a surface of the lens device to define a generally V-shaped flute which opens radially inwardly;
- and
- placing the lens device on the cornea with the projection being received in the cornea so that a region of the cornea overlies the projection and with the V-shaped flute receiving a region of the cornea.
A method for attaching a lens device to the cornea of an eye comprising:
- providing an optic having an optical axis and a flange coupled to the optic and extending radially outwardly of the optic with the flange including first and second radially extending projections adapted for use in attaching the lens device to the cornea and with portions of said projections lying in the same axial plane and on the same side of the optical axis;
- and
- placing the lens device on the cornea with the first projection being received in the cornea so that a region of the cornea overlies the first projection and with the second projection contacting the cornea anteriorly of the first projection.
A method of attaching a lens device to the cornea of a patient comprising:
- placing a lens device having an optic configured for correction of the patient's vision, a flange having increased unit strength relative to said optic affixed to and radially extending from the optic and at least one through hole in said flange sized and adapted to provide for growth of corneal tissue therethrough, in association with said cornea so that corneal tissue overlays at least a portion of said flange.
A lens device for attachment to the cornea of a patient comprising:
- an optic for correction of the patient's vision;
- a flange affixed to and radially extending from said optic, said flange having an increased unit strength relative to said optic;
- and
- at least one through hole in said flange sized and adapted to provide for growth of corneal tissue therethrough.
