Definitions

  • the cover is provided with a domed recess to generally conform to the conical top surface of the lens.
  • the lens is positioned in the closed case, with its base in the recess andits upper conical surface in contact with the complementary inner domed surface of the cover, whereby the danger of catching the base of the lens between the bottom and cover and causing damage thereto is eliminated.
  • the semiscleral lens covers a portion of the sclera and comprises a base, which is in the form of a tapered rim or flange, positioned on the sclera, and a conical corneal portion which covers the cornea.
  • An object of this invention is to provide a contact lens case wherein the lens may easily and properly be positioned in the case without any danger of its base being pinched between the cover and bottom when the case is closed.
  • Another object is to provide a contact lens case having a recess in its bottom to receive the base portion of the lens, whereby parts of the cover cannot pinch or forcibly contact the base portion of the lens when the cover is closed thereon.
  • a further object is to provide a contact lens case, particularly for storing a semi-scleral contact lens, wherein a cylindrical recess is formed in the bottom of the case and a domed recess is formed within the cover.
  • the base portion of the lens is positioned in the cylindrical recess and the domed corneal portion of the lens is received in the domed recess within the cover.
  • FIG. 1 is a perspective view of the contact lens case with the cover in open position
  • FIG. 2 is a top view of a fully opened case
  • FIG. 3 is a sectional view of the fully opened case of FIG. 2, taken along line 2-2 thereon;
  • FIG. 4 is a sectional view through the closed case with the contact lens stored therein.
  • the case of this invention may be made from a variety of metal or plastic materials.
  • the material should be shock and abrasion resistant and inert with respect to the conventional contact lens cleaning and storing solutions.
  • the case is made from suitable plastic material having the above properties and also being somewhat softer than the material of the contact lenses to avoid abrasion of the lenses.
  • suitable plastic material having the above properties and also being somewhat softer than the material of the contact lenses to avoid abrasion of the lenses.
  • Such materi al may be polypropylene, polyethylene and similar synthetic plastic which can be easily molded.
  • the case comprises a platform 1, which may serve as the bottom of the case, and a cover structure 2.
  • Bottom 1 may be solid but preferably it is perforated to permit cleansing and storage fluid to contact the lens stored therein.
  • a recess or depression 3 is formed in the bottom, the depth of the recess being about a third to a half of the thickness of the bottom.
  • the cross section of the recess may be of any shape, such as square, elliptical or circular, it is preferably of circular cross section dimensioned to receive the base section of the contact lens.
  • the semi-scleral contact lens is usually of conical shape having a general circular tapered base section in the form of a rim or flange 4, and a domed corneal section 5 rising therefrom.
  • the base 4 is positioned over the sclera so that the dome 5 is located over the cornea.
  • the cross section of recess 3 is such that it is somewhat larger than base 4 of the lens which is to be stored therein, whereby the base of the lens can be easily placed into recess 3.
  • Wall 6 of recess 3 is of sufficient depth to house base 4, or at least to house the peripheral portion of the base, so that it is not pinched by the cover when the case is closed.
  • the floor portion of recess 3 is formed by a hub and radiat ing spokes structure 7, which is cast integrally with body 8 of the bottom.
  • spokes structure 7 which is cast integrally with body 8 of the bottom.
  • Cover 2 comprises an open ended cylinder 9 in which spokes l0 radiating from hub 11 are located at one end thereof, the cylinder, spokes and hub forming an integral molded structure.
  • the spokes merge with the inner wall of cylinder 9 at a point spaced from the end whereby a clear cylindrical surface 12 is formed.
  • the inner surface 13 of each spoke 10 is arcuate whereby the spokes form a domed space or recess 14 within the cover. This recess generally conforms to the outer conical surface 5 of the corneal portion of the scleral lens.
  • surfaces 13 When the case is closed, surfaces 13 either contact or nearly contact the domed outer surface of the lens whereby the lens is centered with respect to the bottom and the cover of case 1.
  • any undesirable pinching of portions of the edges of base 4, or of other portions of the lens, between the contacting surfaces of the bottom and top is eliminated and the lens is securely held within recesses 3 and 14, as illustrated in FIGS. 3 and 4.
  • the hub and spokes in cover 2 provide spaces in the cover to permit the cleaning and storage fluid to contact the lens.
  • Cover 2 is hinged to bottom 1 by utilizing a conventional hinge structure 16 molded integrally with the bottom and cover.
  • a latch means 17 is provided on bottom 1 having a catch I8 which cooperates with a tongue 19 on the cover to maintain the cover closed, as illustrated in FIG. 4.
  • the latch and tongue means l7, l8 and 19 are molded integrally with the bottom and cover.
  • the front face of the latch means may carry a letter or word to indicate whether the lens in the case is for the left or for the right eye.
