Device and method for examining and/or treating and eye
A device for examining/treating an eye has a base body and an attachment body, which can be combined and applied to the eye. A gel-type liquid is introduced between the two bodies so that the indices can be matched. The interior of the attachment body is provided with a large number of protuberances, ensuring a minimum distance is maintained between the two bodies, allowing air or excess liquid to escape between the two bodies to escape. Only the attachment body, a disposable item producible from cheap materials, needs to be sterilized and a single sterilization is integrated into the production process. The base only needs to be disinfected. This division of the device also allows a large number of base bodies with different configurations to be used with one single attachment body or a large number of attachment bodies with different configurations to be used with one single base body.
1. A device for examining and/or treating an eye, comprising:
a base body; and
an attachment body combinable with the base body, the base body having a first contact surface and the attachment body having a second contact surface and a touch surface, the device being configured to be placed on the eye with the touch surface of the attachment body, wherein
the touch surface is positioned opposite the second contact surface,
the second contact surface has substantially the same shape as the first contact surface, and
the attachment body is combinable with the base body so that the contact surfaces are situated substantially parallel to one another.
2. The device as claimed in claim 1 , wherein the base body and the attachment body can be rotated relative to one another.
3. The device as claimed in claim 2 , wherein the base body and the attachment body can be rotated relative to one another about an optical axis.
4. The device as claimed in claim 1 , wherein at least one of the base body and the attachment body has at least one distancing element for maintaining a minimum spacing between the base body and the attachment body, the at least one distancing element is positioned outside at least one of the first surface and the second contact surface.
5. The device as claimed in claim 4 , wherein at least one of the base body and the attachment body has a plurality of protuberances for maintaining the minimum spacing between the base body and the attachment body.
6. The device as claimed in claim 4 , wherein the device has an optically transparent, deformable intermediate material between the first and second contact surfaces.
7. The device as claimed in one of claims 1 to 4 , wherein when the device is placed on the eye of a patient, only the attachment body is in contact with the patient.
8. The device as claimed in claim 7 , wherein the attachment body is held on the base body via one of a positive connection that can be disconnected and a non-positive connection that can be disconnected.
9. The device as claimed in claim 1 , wherein the base body is configured to enable an ophthalmological examination andlor treatment of the eye.
10. The device as claimed in claim 9 , further comprising:
a mirror for examining and/or treating one of a lateral inner region and a chamber angle of the eye.
11. The device as claimed in claim 1 , wherein
the attachment body has a contact surface substantially adapted to a surface region of the eye to enable the attachment body to be placed on the eye.
12. The device as claimed in claim 11 , wherein the contact surface has edge regions which can be pushed under at least one eyelid of the patient.
13. The device as claimed in claim 11 , further comprising:
a plurality of attachment bodies combinable with the base body, wherein each attachment body is individually packaged and housed in a container ready for use.
14. The device as claimed in claim 11 , where the attachment body can be disinfected or sterilized.
15. The device as claimed in claim 13 , wherein the attachment body is packed in a sterile fashion, and is housed in the container so that an attachment body is combinable with the base body without holding contact of the attachment body and with an optically transparent, deformable, intermediate material introduced between the base body and the attachment body.
