20100160926Constant force intraocular lens injector - An intraocular lens injection device comprises a tubular housing with a passageway extending along its longitudinal axis and a plunger shaft disposed within and moveable along the passageway. The tubular housing and the plunger shaft have frictional engaging features that are configured to produce a varying plunging friction as the plunger is moved along its operating range, to offset changes in the plunging resistance that arise from injecting the IOL into the eye. The variable plunging friction may comprise one or more step changes in unloaded plunging friction, or a curved variation in plunging friction, or both, along at least a portion of the operating range of the plunger shaft. In some embodiments, a slot of varying width in the housing frictionally engages a tab extending transversely from the plunger shaft. In others, a contoured surface on the plunger shaft frictionally engages an orifice in the tubular housing.06-24-2010

20100182569OPHTHALMIC ENDOILLUMINATION USING FIBER GENERATED LIGHT - In one aspect of the invention, an ophthalmic endoilluminator includes at least one pump light source and a scintillator fiber optically coupled to the pump light source. The scintillator fiber receives an output of the pump light source and produces light in a different wavelength range than the output of the pump light source. An optical coupling element couples the light to an optical fiber, which conducts the light into an eye.07-22-2010
20110004149PHACOEMULSIFICATION HOOK TIP - In various embodiments, a phacoemulsification cutting tip with a straight shaft and an angled portion off of the straight shaft may include a hook on the angled portion to move an axis of rotation of the cutting tip closer to alignment with an extended centerline of the shaft. The cutting tip may be configured to torsionally rotate back and forth on an axis perpendicular to a centerline of the shaft (e.g., rotation around a y-axis). In some embodiments, lateral vibrations (e.g., side to side along an x-axis or z-axis perpendicular to the y-axis) that result from torsional rotation around the y-axis in a cutting tip without the hook may be reduced through use of the hook to balance the otherwise eccentrically weighted hook.01-06-2011
20110230728STROBOSCOPIC OPHTHLAMIC ILLUMINATOR - An ophthalmic illuminator is provided that includes a pulse generator to provide amplified pulses and an amplifier to amplify the current pulses to produce amplified pulses. A light source within the ophthalmic illuminator is driven by the amplified pulses so as to stroboscopically illuminate a vibrating ophthalmic surgical tool within the interior of an eye.09-22-2011

20080218863Color Compensating Retinal Safety Filter - A filter and method for filtering an optical beam are disclosed. One embodiment of the filter is an optical filter for filtering an incident light beam, comprising an optically effective material characterized by: a light transmittance of less than 1% for wavelengths below 420 nm; and a light transmittance for wavelengths complementary and near complementary to wavelengths below 420 nm that, combined with the transmittance for wavelengths below 420 nm, will yield a filtered light beam having a luminosity of about 90% and an excitation purity of 5% or less. The complementary wavelengths can be wavelengths above about 640 nm, wavelengths above about 660 nm, and/or wavelengths from about 540 nm to about 560 nm. Further, in one embodiment the difference between the light transmittance just below 420 nm and the light transmittance just above 420 nm can be greater than 90%. Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined. The optically effective material can be optical-grade glass, an optical-grade plastic or polymer, a thin-film dielectric coating, or an optical-grade glass or plastic coated with a dielectric coating. The optical filter can be mounted downstream of an illumination source exit aperture, wherein the illumination source produces the incident light beam, and upstream of a site to be illuminated by the filtered light beam. Alternatively, the optical filter can be operably mounted on a set of viewing optics of a surgical microscope to filter a reflected portion of a light beam produced by an illumination source and used to illuminate a site, such as a surgical site.09-11-2008
