Abstract

The invention provides methods and devices for securing the head of an animal in position while obtaining objective measurements associated with eye health. In one aspect, the devices comprise a rest for receiving a portion of the animal's head and a pole configured to enable the rest to pivot about a first axis of rotation and rotate about a second axis of rotation perpendicular to the first axis of rotation. In an embodiment, the rest can move up and down the second axis of rotation.

First claim

What is claimed is:

1. A device ( 1 ) suitable for securing an animal's eye in position while obtaining objective measurements associated with eye health comprising:
a rest ( 16 ) for receiving a portion of the animal's head;
a clocking adjustment member ( 13 ) connected to the rest ( 16 ); and
a tilt adjustment member ( 8 ) connected to the rest ( 16 );
wherein the tilt adjustment member ( 8 ) comprises a knob ( 8 ) rotatable in a first direction to enable the rest ( 16 ) to pivot to a desired tilt and rotatable in a second direction opposite to the first direction to prevent the rest ( 16 ) from pivoting from the desired tilt.

2. The device ( 1 ) of claim 1 wherein the rest ( 16 ) is at least partially planar.

3. The device ( 1 ) of claim 1 wherein the rest ( 16 ) comprises side flanges ( 26 ) that extend at least partially upward from opposite sides of the rest ( 16 ).

4. The device ( 1 ) of claim 1 comprising an adjustable strap ( 29 ) extending from at least one side of the rest ( 16 ).

5. The device ( 1 ) of claim 1 wherein the rest ( 16 ) comprises a neck flange ( 27 ) that extends downward and outward from one side of the rest ( 16 ).

6. The device ( 1 ) of claim 1 comprising a height adjustment member ( 30 ).

7. The device ( 1 ) of claim 6 wherein the height adjustment member ( 30 ) comprises a stem ( 3 ) having threads configured to enable the rest ( 16 ) to move up and down.

8. The device ( 1 ) of claim 6 wherein the height adjustment member ( 30 ) comprises a knob ( 4 ) rotatable in a first direction to move the rest ( 16 ) up the second axis of rotation ( 102 ) and rotatable in a second direction opposite to the first direction to move the rest ( 16 ) down the second axis of rotation ( 102 ).

9. The device ( 1 ) of claim 1 comprising a base ( 10 ) connected to the pole ( 5 ), the base ( 10 ) attachable to a measurement device ( 105 ) that obtains the objective measurements.

10. The device ( 1 ) of claim 1 comprising a pole ( 5 ) to which the rest ( 16 ), the clocking adjustment member ( 13 ) and the tilt adjustment member ( 8 ) are connected.

11. A device ( 1 ) suitable for securing an animal's eye in position while obtaining objective measurements associated with eye health comprising:
a rest ( 16 ) for receiving a portion of the animal's head;
a pole ( 5 ) configured to enable the rest ( 16 ) to rotate about at least one axis of rotation ( 101 , 102 ); and
an attachment member ( 6 ) configured to pivot relative to the pole ( 5 ) and mount the rest ( 16 ) on the pole ( 5 ), the rest ( 16 ) configured to reversibly connect to and disconnect from the attachment member ( 6 ).

12. A method for securing an animal's eye in position while obtaining objective measurements associated with eye health comprising:
positioning at least a portion of the animal's head in the device ( 1 ) of claim 1 or 11 ; and
adjusting an angle of the animal's head in at least one of a vertical plane or a horizontal plane relative to a measurement device ( 105 ) by rotating the rest ( 16 ) to obtain the objective measurements.

13. The method of claim 12 further comprising adjusting a height of the animal's head relative to the measurement device ( 105 ) by moving the rest ( 16 ).

14. The method of claim 12 wherein positioning at least a portion of the animal's head comprises positioning at least a portion of the animal's neck using the rest ( 16 ).

15. The method of claim 12 further comprising securing the animal's head to the rest ( 16 ) with a strap ( 29 ).

16. The method of claim 12 wherein the measurement device ( 105 ) is selected from the group consisting of an aberrometer, a topographer and a combination thereof.

17. The device ( 1 ) of claim 11 wherein the rest ( 16 ) is one of a plurality of rests ( 200 ) that have different sizes relative to each other.

18. The device ( 1 ) of claim 11 wherein the rest ( 16 ) is one of a plurality of rests ( 200 ) and has side flanges ( 26 ) extending at least partially upward that have a different height relative to the side flanges ( 26 ) of at least one other rest ( 16 ) of the plurality of rests ( 200 ).

19. The device ( 1 ) of claim 11 wherein the rest ( 16 ) is one of a plurality of rests ( 200 ) and has a neck flange ( 27 ) extending downward and outward that has a different length relative to the neck flange ( 27 ) of at least one other rest ( 16 ) of the plurality of rests ( 200 ).

20. A method for obtaining objective measurements associated with eye health comprising:
placing an animal's head on the device ( 1 ) of claim 1 or 11 ; and
measuring one or more parameters associated with an eye of the animal.
