Abstract
Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes determining at least one photic phenomenon experienced by the subject after implantation of the IOL; and applying a plurality of laser pulses to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, a phase shift in the IOL to compensate for the photic phenomenon.

A method for improving vision of a subject having an implanted intraocular lens (IOL), the method comprising:
- determining at least one photic phenomenon experienced by the subject after implantation of the IOL;
- and
- applying a plurality of laser pulses to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, a phase shift in the IOL to compensate for the photic phenomenon, wherein the IOL is a diffractive IOL or a refractive IOL and compensating for the photic phenomena comprises at least partially compensating for a phase delay associated with the phase shift.
A method for improving vision of a subject having an implanted intraocular lens (IOL), the method comprising:
- determining at least one photic phenomenon experienced by the subject after implantation of the IOL;
- and
- applying a plurality of laser pulses to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, a phase shift in the IOL to compensate for the photic phenomenon;
- and
- determining a phase delay associated with the phase shift to compensate for at least one photic phenomena comprises simulations of the optimal higher order aberrations induction based on pupil size analysis.
