    摘要： A gonioscopy lens employs a plurality of mirror sets (30a, 32a; 30b, 32b; 30c, 32c; 30d, 32d) so that substantially the entire periphery of the anterior chamber (42) of an eye (22) can be viewed without rotating or moving the contact lens (10). Each mirror set comprises a first mirror (32a; 32b; 32c; 32d) positioned anterior to the eye on one side of the optical axis (24) and a second mirror (30a; 30b; 30c; 30d) positioned posterior to the first mirror on the opposite side of the optical axis. Each set is oriented relative to each other so that the second mirror receives light rays (40) from the peripheral portion of the anterior chamber (42), reflects those rays from the second mirror to the first mirror, and then reflects the light rays in a generally anterior direction (40b) so that they can be used by an ophthalmologist employing the lens. The image viewed by the ophthalmologist is upright and located over its actual position.

    摘要： An ophthalmic lens (70) utilized for observing the fundus (38) of an eye (12) using through the lens illumination and for delivering a focused laser beam to the fundus includes a contact lens (16) and an aspheric entry lens (18). In combination, the lenses provide an aerial image of the fundus anterior to the entry lens.

    摘要： An attachment (54) for a slit lamp that permits the operator to view the superimposition of an image of a patient's eye and a second image that may comprise a fluorescein angiogram (56) or other photographic image of the patient's eye, or an image formed by a CRT or other display system. The slit lamp includes objective means (46) for forming the first image directed along a first optical path, and viewing means (48) comprising an eyepiece (50,52), the viewing means (48) being attachable to the objective means (46) such that the eyepiece (50,52) is positioned along the first optical path. The attachment (54) includes a body (60), a beamsplitter (62), and an image forming system (64,66,68,70). The body (60) includes means (98,104) for attaching the body (60) between the objective means (46) and viewing means (48), and also includes a passage (76) through which the first image can pass along the first optical path to the viewing means (48). The beamsplitter (62) is mounted in the body (60), and positioned in the first optical path. The image forming system (64,66,68,70) projects the second image into the beamsplitter (62), such that a portion of the second image is reflected along the first optical path. The image forming system (64,66,68,70) may include a zoom lens system (64,66) for adjusting the size of the second image. The zoom lens system (64,66) may comprise a pair of lenses and positioning means including an inner tube (82) having a pair of helical slots (126) and a pair of outer tubes (140,142) having a pair of longitudinal slots (144,146). Beamsplitter positioning means (110,112) are also provided for permitting the operator to precisely position the first and second images with respect to one another.

    摘要： A lens system for use with a scanning laser ophthalmoscope to produce a wide field of view includes a first lens set and a second lens set. The first lens set provides an aerial image of the fundus of an eye along an aerial image plane anterior to the first lens set. A second lens focuses laser light from a scanning laser ophthalmoscope on the aerial image, which is then refocused by the first lens set on the fundus. The second lens set also receives and provides reflected light focused at the aerial image and redirects it to the entrance pupil of the ophthalmoscope in a substantially collimated form.
