摘要：
Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes determining a deviation in position of at least one optical element from a reference line corresponding to alignment of the apex of the cornea, center of the pupil, center of the IOL, and fovea, and/or determining a tilt of at least one of the optical elements relative to the reference line. The method can further include applying a plurality of focused laser pulses to a selected area of the implanted IOL to produce, through refractive index writing, a phase change pattern on the IOL that is configured to compensate for the deviation(s) and/or tilt to improve the foveal vision of the subject.
