Abstract
A gonioscopic lens system which provides a real image of the anterior chamber angle of a patient's eye. The lens system includes a first lens group having a concave posterior surface configured to be placed on a patient's eye, a second lens group optically aligned with the first lens group; and a stop positioned between the first and second lens groups. An achromatic gonioscopic lens system which provides a real image of the anterior chamber angle of a patient's eye is also provided, as well as an ophthalmoscopy lens system for viewing both the anterior chamber angle and the retina of a patient's eye.
Claims16
An ophthalmoscopy lens system for viewing both the anterior chamber angle and the retina of a patient's eye, comprising:
- a first lens group having a concave posterior surface configured to be placed on a patient's eye;
- and
- a second lens group optically aligned with said first lens group, wherein said second lens group includes a hole extending through the thickness of said second lens group along the optical axis of the ophthalmoscopy lens system;
- wherein the ophthalmoscopy lens system may be used to not only provide an image of a patient's anterior chamber angle but also to provide a direct view of a patient's retina through said hole in said second lens group.
An ophthalmoscopy lens system comprising:
- a first lens group comprising a contact lens element having a concave posterior surface configured to be placed on a patient's eye;
- and
- a second lens group optically aligned with said first lens group, wherein said second lens group includes a hole extending through the thickness of said second lens group along the optical axis of the ophthalmoscopy lens system;
- wherein the ophthalmoscopy lens system is configured to provide not only an image of anterior structures within the patient's eye but also a direct view of a patient's retina through said hole in said second lens group.
