|Embodiments of the present invention provide a system and method for shaping |
an annular focal spot pattern to allow for more efficient optical coupling to a small
gauge optical fiber. An embodiment of the present invention can include an
illumination source operable to transmit an optical beam along an ...
|An ophthalmic surgical system includes a display device and a user interface. |
The display device generates a display on an image of a patient's eye comprising
a plurality of non-overlapping display sectors. Each display sector displays one of
a plurality of user-selectable surgical parameters. A user ...
|A white light source includes a light-emitting diode (LED) configured to emit white |
light in an angular distribution. The white light source further includes a light
guide and a light collector configured to collect light across the angular
distribution. The light collected by the light collector contributes to a total ...
|An ophthalmic illuminator includes a one or more light combining stages |
arranged in series to augment a white light source with various color spectral
bands. A first stage combines white light from a white light source with colored
light from a first color source. Each subsequent stage in the series adds its ...
|A surgical system and cassette, the cassette having an identification method that |
is specific to the cassette. Suitable methods include bar coding or Radio
Frequency Identification (“RFID”). Cassette information that may be encoded
include features such as lot number and performance characteristics, such ...
|A white light source includes a light-emitting diode configured to emit light of a |
characteristic wavelength. The white light source also includes at ...
|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 ...
|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 ...
|A system, apparatus and method for spatially distributed, spectrally neutral |
optical attenuation are disclosed. One embodiment of the apparatus comprises:
an attenuator fin plate; a set of attenuator fins, wherein each of the fins is
operably coupled to the fin plate at a preset fin angle to the fin plate normal ...
|An ophthalmic endoilluminator has a power supply coupled to a light source, a |
controller, a collimation device, an alignment device, a lens, and an optical fiber.
The light source has three light emitting diodes. Each of the three light emitting
diodes produces a different color light. The controller controls the ...
