Abstract: Improved devices, systems, and methods for planning cataract surgery on an eye of a patient incorporate results of prior corrective surgeries into a planned cataract surgery of a particular patient by driving an effective surgery vector function based on data from the prior corrective surgeries. The exemplary effective surgery vector employs an influence matrix which may allow improved refractive corrections to be generated so as to increase the overall efficacy of a cataract surgery by specifying one or more parameters of an intraocular lens (IOL) to be implanted during the cataract surgery.

Abstract: An enhanced dynamic range wavefront sensing system includes a light source disposed on a first side of an optically transmissive device, a wavefront sensor disposed on a second side of an optically transmissive device, a relay imaging system disposed between the optically transmissive device and the wavefront sensor, and means for adjusting a distance between the light source and the optically transmissive device. Beneficially, the relay imaging system includes a range-limiting aperture to insure that the wavefront sensor never goes out of range so that a feedback system can be employed to move the light source one focal length away from the optically transmissive device.

Abstract: A metrology system and method uses pulsed light to allow continuous movement of a target relative to the sensor. A metrology system and method uses dynamic adjustment of tilt in a system. A metrology system and method calibrates the system to remove inherent optical aberrations in the system. Filtering may also be used in the system to increase accuracy.

Abstract: Metrology is performed using short, temporally resolved measurements in order to “freeze” the deformation of the object at a particular instant in time. The pulsed light beams are used to conduct metrology of moving objects and objects which are moved relative to the detector for measurement thereof. The motion may be translational, spiral and/or rotational. The duty cycle of the light source may be varied to in accordance with the control of the operation of the detector to perform metrology using a reduced total exposure of an object, while increasing the amount of light available for the measurement.
