    摘要： A method for fitting and designing an ophthalmic lens for a presbyope that yields improved visual acuity in general, and takes into account individual fitting characteristics. More specifically, a method for fitting and designing a contact or intraocular lens which takes into account material properties of the lens by observing the “print through” associated with the lens as an indicator of the topography of the lens. The term “print through” is used to refer to any change in lens topography on the front surface of the lens as a result of changes in topography on the back surface of the lens. If a significant amount of “print through” is observed, this generally indicates that the multifocal function of the lens is properly being performed. In such a situation, the clinician can then adjust the add power to the desired level. If there is not a significant amount of “print through”, this generally indicates that the multifocal function of the lens is not properly being performed. In this latter situation, by observing the reduced “print through” associated with such a lens, the clinician can instead bias one lens of a lens pair for distance power and the other lens of a lens pair for near power. Alternatively, each lens of the lens pair can be biased for some combination of distance power and near power.

    摘要翻译： 一种用于配戴和设计用于长角镜的眼镜片的方法，其通常产生改善的视敏度，并且考虑到各自的装配特性。 更具体地，涉及一种通过观察与透镜相关联的“打印通过”作为透镜的形貌的指示符来考虑到透镜的材料性质来配合和设计接触或眼内透镜的方法。 术语“打印通过”用于指透镜表面上的形状变化的结果，透镜前表面上的透镜形状的任何变化。 如果观察到大量的“打印通”，则这通常表示正确地执行透镜的多焦点功能。 在这种情况下，临床医生可以将添加功率调整到所需的水平。 如果没有大量的“打印通过”，则这通常表示镜头的多焦点功能没有被正确地执行。 在后一种情况下，通过观察与这种透镜相关联的减少的“打印通过”，临床医生可以改变偏置透镜对的一个透镜以用于距离功率，并且透镜对的另一个透镜偏压近距离。 或者，透镜对的每个透镜可以偏置距离功率和近功率的一些组合。

    摘要： 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.

    摘要： An arrangement for measuring desired parameters of a contact lens by optical sectioning which comprises a support fixture on which a contact lens is positioned. The support fixture includes a container in which a pedestal is positioned, and the container is filled with a saline solution. The contact lens is placed on the pedestal completely immersed in the saline solution. A line of light is generated and directed by imaging and shaping optical elements over the edge of the container and through a selected diameter of the contact lens. An imaging camera detects and image of the light scattered at the surfaces of the contact lens at the selected diameter, which is captured by a frame grabber and is digitally stored for subsequent image processing and determination of the desired parameters of the contact lens. The analysis provides at least four basic parameters of the contact lens including the diameter (D), front radius of curvature (FC), back radius of curvature (BC), and center thickness (CT), and can also provide the lenticular curve radius, the peripheral curve radius, the sagittal height, aspherical forms and deviations of the several measured curvatures, and the power of the lens.
