摘要： A system includes: a swept laser light source generating laser light having a frequency swept across a frequency bandwidth as a function of time; a sample path directing a first portion of the laser light to an eye as a probe beam and receiving a returned portion of the probe beam from the eye; a reference path passing therethrough a second portion of the laser light, the reference path having a defined optical path length; and a detector receiving the returned portion of the probe beam from the eye and the second portion of the laser light from the reference path, and in response thereto outputting an optical coherence tomography (OCT) output signal having OCT peaks whose relative timing represents the depths of surfaces of structures of the eye, wherein the sample path includes a fiducial generator which produces a fiducial peak in the OCT output signal.

摘要： An optical coherence tomography (OCT) interferometer includes at least a first optical fiber of a first type having a first length, in series with a second optical fiber of a second type which is different than the first type and having a second length, in at least one of the sample path and/or the reference path of the OCT interferometer. The dispersion characteristics of the first optical fiber and the second optical fiber are significantly different than each other. As a result, the total group delay dispersion of a first portion of the laser light passing through the sample path and the total group delay dispersion of the second portion of the laser light passing through the reference path may offset each other at the detector.

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 at least one biometric parameter and a representation of a corneal topography of the patient's eye; a processor coupled to a computer readable medium having stored thereon a program that upon execution causes the processor to receive the at least one biometric parameter and obtain corneal spherical aberration based upon the representation of the corneal topography, and the processor calculates an optimized optical power to obtain a desired postoperative condition by applying the received value and obtained corneal spherical aberration to a modified regression, wherein the modified regression is of the form: optical power=Regression+constant0*(corneal spherical aberration) or optical power=constant1*(biometric parameter)+constant0*(corneal spherical aberration). Constant1 and constant0 comprise an empirically derived factor across other eyes. The Regression comprises a classical regression and biometric parameter is related to the values of the at least one measured eye's parameter.
