Abstract
A model human eye comprising a cylindrical base portion comprising a bowl-shaped substrate disposed therein, and a plurality of retinal layers stacked on the surface of that bowl-shaped substrate. The model eye further comprises a hemi-spherical-shaped top portion comprising a visually transparent cornea portion and a visually opaque sclera portion comprising an inner surface, an annular iris continuously attached to the inner surface and extending inwardly therefrom, and a lenticular bag continuously attached to the iris, wherein the iris in combination with the lenticular bag and the cornea portion define an anterior chamber. The top portion is attached to the base portion to define a posterior chamber.
Claims18
A model human eye for use in practicing surgical techniques, comprising:
- a bowl-shaped substrate;
- a plurality of retinal layers stacked on said bowl-shaped substrate successively, wherein said plurality of layers comprises:
- a first retinal layer comprising a first color;
- a second retinal layer disposed over said first layer, wherein said second layer comprises a second color;
- and
- a third retinal layer disposed over said second layer, wherein said third layer comprises a third color, wherein the first color, the second color, and the third color differ;
- an integrally molded hemi-spherical-shaped top portion comprising a visually transparent cornea portion and a visually opaque sclera portion comprising an inner surface, wherein:
- said cornea portion comprises a center point and a peripheral edge;
- said center point is formed to comprise a minimum thickness between about 0.45 mm and about 0.55 mm;
- and
- said peripheral edge is formed to comprise a maximum thickness of between about 0.6 mm and about 0.8 mm;
- an annular iris continuously attached to said inner surface and extending inwardly therefrom;
- a lenticular bag continuously attached to said iris, wherein said iris in combination with said lenticular bag and said cornea portion define an anterior chamber;
- a first fluid disposed in said anterior chamber, wherein said first fluid comprises a first viscosity;
- wherein said top portion is attached to said base portion to define a posterior chamber;
- and
- a second fluid disposed in said posterior chamber, wherein said second fluid comprises a second viscosity, wherein said second viscosity is greater than said first viscosity;
- wherein said model human eye is structurally suited for practicing surgical techniques selected from the group consisting of:
- a retinal membrane peel;
- treatment of a choriodal neovascular membrane;
- argon laser trabeculoplasty;
- and
- Descemets Stripping Endothelial Keratoplasty.
A method to practice surgical techniques on a model human eye, comprising:
- supplying a model human eye comprising:
- a bowl-shaped substrate;
- a plurality of retinal layers stacked on said bowl shaped substrate successively,
- wherein said plurality of layers comprises:
- a first retinal layer comprising a first color;
- a second retinal layer disposed over said first layer, wherein said second layer comprises a second color;
- and
- a third retinal layer disposed over said second layer, wherein said third layer comprises a third color, wherein the first color, the second color, and the third color differ;
- an integrally molded hemi-spherical-shaped top portion comprising a cornea portion and a visually opaque sclera portion comprising an inner surface, wherein:
- said cornea portion comprises a center point and a peripheral edge;
- said center point is formed to comprise a minimum thickness between about 0.45 mm and about 0.55 mm;
- and
- said peripheral edge is formed to comprise a maximum thickness of between about 0.6 mm and about 0.8 mm;
- an annular iris continuously attached to said inner surface and extending inwardly therefrom;
- a lenticular bag continuously attached to said iris, wherein said iris in combination with said lenticular bag and with a portion of said inner surface disposed above said iris define an anterior chamber;
- a first fluid disposed in said anterior chamber, wherein said first fluid comprises a first viscosity;
- wherein said top portion is attached to said base portion to define a posterior chamber;
- and
- a second fluid disposed in said posterior chamber, wherein said second fluid comprises a second viscosity, wherein said second viscosity is greater than said first viscosity;
- wherein said model human eye is structurally suited for practicing surgical techniques selected from the group consisting of:
- a retinal membrane peel;
- treatment of a choriodal neovascular membrane;
- argon laser trabeculoplasty;
- and
- Descemets Stripping Endothelial Keratoplasty;
- supplying a face manikin formed to mimic a human-face comprising a raised, face-mimicking structure surrounded by a trough, wherein said face-mimicking structure comprises two eye sockets extending therethrough, an exterior surface, and an interior surface, two attachment straps wherein each attachment strap comprises a first end attached to said interior surface adjacent one of the eye sockets, two attachment buckles wherein each attachment buckle attached to said interior surface adjacent one of the eye sockets;
- wherein said exterior surface comprises:
- an eye brow element disposed adjacent a first side of each eye socket;
- a nose feature disposed between the eye sockets and adjacent a second an opposing side of the eye sockets;
- and a mouth feature disposed adjacent the nose feature;
- said method further comprising:
- positioning said model eye against the interior surface of said face-mimicking structure such that the cornea portion extends outwardly from an eye socket;
- and
- releasably attaching said model eye to said face-mimicking structure using an attachment strap and an attachment buckle.
