Abstract
Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes applying a plurality of laser pulses to the IOL. The laser pulses can be configured to produce, by refractive index writing on the IOL, a predetermined change in phase profile of the IOL to increase spectacle independence.
Claims19
A method for improving vision of a subject, the method comprising:
- receiving, by a control system, parameters related to spectacle dependence of an eye of a subject having an implanted intraocular lens (IOL);
- calculating, based on the parameters, a pattern of laser pulses and selected areas of the IOL to which the laser pulses are to be applied to change a phase profile of the IOL to increase spectacle independence;
- estimating, by the control system, a phase delay based at least in part on measurements associated with subject-specific through-focus visual acuity;
- and
- applying, based at least on one or more of the phase delay, the pattern of laser pulses, or the selected areas of the IOL, a plurality of laser pulses to the selected areas of the IOL to change a refractive index of the selected areas, by refractive index writing.

- and
- applying, by a pulsed laser system under control of the control system, a plurality of laser pulses to the selected areas of the IOL to change a refractive index of the selected areas, by refractive index writing, wherein the measurements are acquired prior to the application of the laser pulses to the IOL.
