METHODS FOR SELECTING INTRAOCULAR LENSES AND RELAXING INCISIONS FOR CORRECTING REFRACTIVE ERROR

摘要

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.

主权项

1. A method for selecting a tonic intraocular lens (IOL) and a relaxing incision combination effective to correct astigmatism when the toric IOL is implanted in an eye in a first off-axis orientation in combination with placement of the relaxing incision in a second off-axis position, the method comprising:
(a) receiving a predetermined magnitude for the astigmatism to be corrected; and (b) identifying a toric IOL-relaxing incision combination, wherein the toric IOL comprises a first astigmatism correcting power and the relaxing incision comprises a second astigmatism correcting power, the combination of any two of the first astigmatism correcting power, the second astigmatism correcting power, and the magnitude of astigmatism being corrected is greater than the first astigmatism correcting power, the second astigmatism correcting power, or the magnitude of astigmatism not in the combination.
