    • 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.
    • 一种前房角镜系统,其提供患者眼睛的前房角度的真实图像。 透镜系统包括具有被配置为放置在患者眼睛上的凹后表面的第一透镜组,与第一透镜组光学对准的第二透镜组; 以及位于第一和第二透镜组之间的止动件。 还提供了提供患者眼睛的前房角度的真实图像的消乐差角镜镜片系统,以及用于观察患者眼睛的前房角度和视网膜的检眼镜系统。

    • 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.
    • 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。
