摘要： An ophthalmic lens which has three elements, a contact lens, a center lens, and an entry lens. The lens produces a magnified aerial image of the fundus of the eye. The lens is particularly useful because it provides high magnification and detail of the fundus as well as good stereoscopic field.

摘要： An ophthalmic lens having two elements, a contact lens and an entry lens. The lens produces a magnified aerial image of the fundus of the eye, and can also be used for laser delivery to the fundus. The lens is particularly useful because it provides high magnification and detail of the fundus as well as excellent steroscopic field.

摘要： An ophthalmic lens which has three elements, a contact lens, a center lens, and an entry lens. The lens produces a wide field, aerial image of the fundus of the eye. The lens is particularly useful because it provides high resolution of the peripheral retina, and causes little or no distortion of the laser beam used for peripheral fundus laser treatment.

摘要： An attachment 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 or other photographic image of the patient's eye, or an image formed by a CRT or other display system. The slit lamp includes an objective for forming the first image directed along a first optical path, an eyepiece, being attachable to the objective such that the eyepiece is positioned along the first optical path. The attachment includes a body, a beamsplitter, and an image forming system. The body includes an attachment for attaching the body between the objective and viewing means, and also includes a passage through which the first image can pass along the first optical path to the eyepiece. The beamsplitter is mounted in the body, and positioned in the first optical path. The image forming system projects the second image onto the beamsplitter, such that a portion of the second image is reflected along the first optical path. The image forming system may include a zoom lens system for adjusting the size of the second image. The zoom lens system may comprise a pair of lenses and positioning means including an inner tube having a pair of helical slots and a pair of outer tubes having a pair of longitudinal slots. A beamsplitter positioning device is also provided for permitting the operator to precisely position the first and second images with respect to one another.
摘要翻译：一种用于裂缝灯的附件，其允许操作者观看患者眼睛的图像和可包括患者眼睛的荧光血管造影或其他摄影图像的第二图像的叠加，或由CRT或其他显示器形成的图像系统。狭缝灯包括用于形成沿着第一光路指向的第一图像的目标，目镜，可附接到物镜，使得目镜沿着第一光路定位。附件包括主体，分束器和图像形成系统。主体包括用于将物体附接在物镜和观察装置之间的附件，并且还包括第一图像可以沿着第一光路通过到目镜的通道。分束器安装在主体中，并且位于第一光路中。图像形成系统将第二图像投影到分束器上，使得第二图像的一部分沿着第一光路被反射。图像形成系统可以包括用于调整第二图像的尺寸的变焦透镜系统。变焦透镜系统可以包括一对透镜和定位装置，其包括具有一对螺旋槽的内管和具有一对纵向槽的一对外管。还设置分束器定位装置，用于允许操作者相对于彼此精确地定位第一和第二图像。

摘要： An ophthalmoscopic prism, for example a gonioscope, has an optically transparent body, the distal end carries a viewing surface preferably oriented perpendicularly to the optical axis of the body, the proximal end of the prism carries a concave surface having a curvature similar to the curvature of the cornea of a patient. The proximal end has at least one planar surface extending outwardly and distally from a location adjacent the periphery of the concave surface. The body has an index of refraction that provides total internal reflection to a viewer looking through the viewing surface even when the planar surface is at least partially wetted with a fluid.

摘要： A contact lens for use in connection with transscleral cyclophotocoagulation. The lens has a planar entry surface and a frustoconically-shaped exit surface that contacts the sclera surrounding the cornea. The central portion of the lens is opaque to prevent stray laser light from entering the optical portion of the eye during laser application.
