摘要： A contact-type ophthalmic lens for use in diagnosis and laser surgery has a contact lens (14), an entry lens (16), and an intermediate lens (18). The lenses are aligned along their optical axes. The anterior surface of the contact lens has an aspheric surface with a high power. The intermediate lens is a meniscus lens with a concave posterior surface and a convex anterior surface. Both surfaces of the entry lens are convex and aspheric. This combination of lenses provides a very wide field of view, allowing regions of the eye anterior to the equator to be readily viewed in an aerial image focused in a plane (50) anterior to the lens system.

摘要： An indirect ophthalmoscopy lens (10) comprises two or more elements (16, 30). The elements (16, 30) are movable by the physician relative to each other to vary the magnification provided in an aerial image (I) of the fundus.
摘要翻译： 间接检眼镜（10）包括两个或多个元件（16,30）。 元件（16,30）可由医师相对于彼此移动以改变在眼底的空间图像（I）中提供的放大倍率。

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 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 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.
