Abstract
A fiducial is generated on an internal anatomical structure of the eye of a patient with a surgical laser. A toric artificial intraocular lens (IOL) is positioned so that a marker of the toric IOL is in a predetermined positional relationship relative to the fiducial. This positioning aligns the toric IOL with the astigmatic or other axis of the eye. The toric IOL is then implanted in the eye of the patient with high accuracy.
Claims20
A method of implanting an implantable device in an eye of a patient, the method comprising:
- generating a fiducial on an anatomical structure of the eye, the anatomical structure being a cornea or a lens capsule of the eye, the fiducial being located outside of an area corresponding to a maximum natural size of a pupil of the eye, and inside of an area having a predetermined size corresponding to a dilated pupil size which is larger than the maximum natural size of the pupil;
- placing the implantable device inside the eye, the implantable device having a marker located outside of the area corresponding to the maximum natural size of the pupil and inside of the area having the predetermined size;
- and
- positioning the implantable device so that the marker of the implantable device is in a positional relationship relative to the fiducial.
