US 12,508,124 B2 · Methods for selecting intraocular lenses and relaxing incisions for correcting refractive error

Abstract

The disclosure provides a method for selecting toric intraocular lenses (IOL) and relaxing incision for correcting refractive error. The one or more toric IOL and relaxing incision combinations can be used for off-axis correction of refractive errors such as astigmatism. The disclosure provides a method for selecting toric IOL and relaxing incision combinations that have combined astigmatism correcting powers and off-axis positions or orientations of the astigmatism correcting axes of the toric IOL and relaxing incision that are effective to yield lower residual astigmatism than on axis correction methods. The toric IOL and relaxing incision combinations also allow the user to avoid incisions that will radially overlap with a cataract incision thereby provided improved outcomes.

Claims22

Dependent claims

A method to avoid incision overlap in an eye comprising:

obtaining an axis of an astigmatism in the eye to be corrected;
obtaining a first arc length and a first off-axis orientation of an operative incision in the eye, such that the first off-axis orientation is different from the astigmatism axis;
obtaining a second arc length of one or more relaxing incisions to at least partially correct the astigmatism;
and
determining a second off-axis orientation of the one or more relaxing incisions such that the second off-axis orientation is different from the astigmatism axis and the first off-axis orientation, wherein the second off-axis orientation is based on the first arc length and the first off-axis orientation and the second arc length, such that the one or more relaxing incisions do not overlap with the operative incision.

2 more elements

A method comprising:

obtaining astigmatism information of an astigmatism in an eye to be corrected, wherein the astigmatism information comprises an axis of the astigmatism;
selecting two or more astigmatic correction devices and interventions to correct the astigmatism based on the astigmatism information, wherein a first of the two or more astigmatic correction devices and interventions is implanted in the eye in a first off-axis orientation different from the axis of the astigmatism, and a second of the two or more astigmatic correction devices and interventions is placed in a second off-axis orientation different from the axis of the astigmatism and the first off-axis orientation;
and
determining a list of one or more intraocular lenses (IOLs) and one or more relaxing incisions for each of the two or more astigmatic correction devices and interventions based on the astigmatism information and the selected two or more astigmatic correction devices and interventions.
