Abstract
A sensing system and method to detect and determine magnitude and direction of ciliary body movement within an eye of a patient is disclosed. The invention comprises a permanent magnet (PM) positioned in the ciliary body, and a sensing device (SD) positioned adjacent the ciliary body and configured to detect displacement of the permanent magnet relative to the sensing device via movement of the ciliary body. The invention also comprises a data processing device (DPD) configured to determine magnitude and direction of the ciliary body movement based on the displacement of the permanent magnet detected by the sensing device.
Claims22
A sensing system to detect and determine magnitude and direction of ciliary body movement within an eye of a patient, said system comprising:
- a permanent magnet (PM) positioned in the ciliary body;
- a sensing device (SD) positioned adjacent the ciliary body and configured to detect three-dimensional displacement of the permanent magnet relative to the sensing device via movement of the ciliary body during accommodation and disaccommodation;
- and
- a data processing device (DPD) configured to determine magnitude and direction of the ciliary body movement based on the displacement of the permanent magnet detected by the sensing device and configured to dynamically calculate velocity and acceleration of the ciliary body movement during accommodation and disaccommodation.
A method of ciliary body movement within an eye, said method comprises:
- positioning a permanent magnet (PM) in the ciliary body;
- positioning a sensing device (SD) adjacent the ciliary body;
- detecting three-dimensional displacement of the permanent magnet relative to the sensing device via movement of the ciliary body during accommodation and disaccommodation;
- using a data processing device to determine magnitude and direction of the ciliary body movement based on the displacement of the permanent magnet detected by the sensing device;
- using a data processing device to dynamically calculate velocity and acceleration of the ciliary body movement during accommodation and disaccommodation based on the displacement of the permanent magnet detected by the sensing device.
The method of claim 19 wherein said permanent magnet is positioned such that disaccommodation and accommodation of the ciliary body is detectable.
