Intraoperative assessment of implant positioning

Abstract

An intraocular implant device includes: (1) a lens portion; and (2) a peripheral portion surrounding the lens portion, wherein the peripheral portion includes multiple fiducials including a first fiducial, a second fiducial, and a third fiducial, the first fiducial, the second fiducial, and the third fiducial are positioned in the peripheral portion so that the third fiducial is displaced from a line segment connecting the first fiducial and the second fiducial.

What is claimed is: 
     
         1 . A method of positioning an intraocular implant device, comprising:
 determining an optical center of the intraocular implant device according to multiple fiducials in the intraocular implant device; and   determining a position of the optical center relative to a target position.   
     
     
         2 . The method of  claim 1 , further comprising directing repositioning of the intraocular implant device to translate the optical center towards the target position. 
     
     
         3 . A method of positioning an intraocular implant device, comprising:
 determining an optical plane of the intraocular implant device according to multiple fiducials in the intraocular implant device; and   determining an orientation of the optical plane relative to a target orientation.   
     
     
         4 . The method of  claim 3 , further comprising directing repositioning of the intraocular implant device to rotate the optical plane towards the target orientation. 
     
     
         5 . A method of positioning an intraocular implant device, comprising:
 determining an optical plane of the intraocular implant device according to multiple fiducials in the intraocular implant device; and   determining a position of the optical plane relative to a target position.   
     
     
         6 . The method of  claim 5 , further comprising directing repositioning of the intraocular implant device to translate the optical plane towards the target position.
