摘要： 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.

摘要： Swept source optical coherence tomography (SS-OCT) systems and methods may employ down-conversion. Down-converter systems and methods may utilize a distribution element and a frequency down shifter. The distribution element may receive an output signal of a photo detection device, the output signal comprising a first frequency component at or below a maximum conversion frequency and a second frequency component above the maximum conversion frequency. The distribution element may send the first frequency component to an analog to digital (A/D) converter and send the second frequency component to a frequency down shifter. The frequency down shifter may down shift the second frequency component to a frequency at or below the maximum conversion frequency to form a down shifted second frequency component. The frequency down shifter may send the down shifted second frequency component to the A/D converter.

摘要： A system for predicting optical power for an intraocular lens based upon measured biometric parameters in a patient's eye includes: a biometric reader capable of measuring one or more biometric parameters of the patient's eye and obtaining at least one value for at least one of the one or more biometric parameters, and further measuring a representation of a corneal topography of the patient's eye; a processor; and a computer readable medium coupled to the processor and having stored thereon a program that upon execution causes the processor to: receive the at least one value; obtain a corneal spherical aberration (SA) based upon the representation of the corneal topography; and calculate an optimized optical power to obtain a desired postoperative condition by applying the received at least one value and the obtained corneal spherical aberration to a modified regression.
