    摘要： A method is provided for increasing the depth of focus of an eye of a patient. A visual axis of the eye is aligned with an instrument axis of an ophthalmic instrument. The ophthalmic instrument has an aperture through which the patient may look along the instrument axis. A first reference target is imaged on the instrument axis at a first distance with respect to the eye. A second reference target is imaged on the instrument axis with the ophthalmic instrument at a second distance with respect to the eye. The second distance is greater than the first distance. Movement is provided such that the patient's eye is in a position where the images of the first and second reference targets appear to the patient's eye to be aligned. A mask comprising a pin-hole aperture having a mask axis is aligned with the instrument axis such that the mask axis and the instrument axis are substantially collinear. The mask is applied to the eye of the patient while the alignment of the mask axis and the instrument axis is maintained. Maintaining alignment of the mask axis and the instrument axis may be facilitated by capturing an image of the eye.

    摘要翻译： 提供了一种用于增加患者眼睛的焦点深度的方法。 眼睛的视轴与眼科仪器的仪器轴线对准。 眼科器具具有孔，患者可沿着该孔观察仪器轴线。 第一参考目标在仪器轴上相对于眼睛以第一距离成像。 第二参考目标在仪器轴上与眼科仪器相对于眼睛相距第二距离成像。 第二距离大于第一距离。 提供运动，使得患者的眼睛处于第一和第二参考对象的图像对患者眼睛看起来对准的位置。 包括具有掩模轴的针孔的掩模与仪器轴线对准，使得掩模轴线和仪器轴线基本上共线。 当保持掩模轴和仪器轴的对准时，将掩模施加到患者的眼睛。 通过捕捉眼睛的图像可以方便地保持掩模轴和仪器轴的对准。

    摘要： A catheter handpiece apparatus and method for delivering a desired dose with minimal potential for contamination of the injected substance and rapid, accurate delivery of the desired dose. In one embodiment, a carriage assembly affixed to an inner lumen is slidably located within a handpiece housing equipped with an outer lumen. The carriage assembly receives a dose carpule. An actuator knob cocks the carriage assembly and a spring-powered actuator mechanism. After the catheter is maneuvered to a desired injection site and a desired dose is set, depressing a first trigger causes the inner lumen tip to extend beyond the outer lumen into the injection site. Depressing a second trigger causes the actuator mechanism to push the desired dose from the dose carpule through the inner lumen into the injection site. A second embodiment provides a catheter handpiece with a carriage assembly cocking lever and an operator-powered dose delivery mechanism.
