Abstract: A double-sided aspheric diffractive multifocal lens and methods of manufacturing and design of such lenses in the field of ophthalmology. The lens can include an optic comprising an aspheric anterior surface and an aspheric posterior surface. On one of the two surfaces a plurality of concentric diffractive multifocal zones can be designed. The other surface can include a toric component. The double-sided aspheric surface design results in improvement of the modulation transfer function (MTF) of the lens-eye combination by aberration reduction and vision contrast enhancement as compared to one-sided aspheric lens. The surface having a plurality of concentric diffractive multifocal zones produces a near focus, an intermediate focus, and a distance focus.

Abstract: The present invention provides a device and method for inserting an IOL into an eye of a patient. The IOL injector is configured to automatically load an IOL into the injector by folding and aligning the IOL into a lens cartridge of the injector without manual manipulation of the IOL by the physician during the procedure. The injector is configured to properly orient and align the IOL within the injector and maintain proper alignment throughout delivery of the IOL to the eye of a patient and thereby ensuring that the IOL is properly positioned and oriented at a predetermined location in the eye.

Abstract: A system is provided for positioning a substrate having a surface required to be characterized with a contact angle measurement. The system includes a stage which supports the substrate and a dispenser assembly having a dispensing tip through which a liquid droplet having a preselected volume is dispensed onto the surface of the substrate. A first actuating mechanism moves the stage in response to first actuation signals and a second actuating mechanism which changes the vertical spacing between the dispensing tip and the surface of the substrate and dispenses the liquid droplet from the dispenser assembly in response to second actuation signals. A controller is connected to the actuating mechanisms and delivers the first and second actuation signals to the first and second actuating mechanisms, respectively, so as to place the liquid droplet at a predetermined location on the surface of the substrate for performing the contact angle measurement.
