Abstract: Certain aspects of the present disclosure provide for in-situ intraocular lens (IOL) tilt determination and for providing information associated with the angle of IOL tilt intraoperatively. An example method includes imaging an IOL within a patient's eye via an ophthalmic imaging device, in-situ, after implantation of the IOL within the patient's eye; processing the image of the IOL within the patient's eye to determine an angle of tilt of the IOL; and outputting information associated with the angle of IOL tilt to a user interface.

Abstract: Disclosed are apparatus, systems, and methods for objectively assessing accommodation in an eye. For example, a method for objectively assessing accommodation can comprise displaying, at a far display, a stimulus target for a first duration and displaying, at a near display, the stimulus target for a second duration. The stimulus target displayed at the near display can be projected onto a first beam splitter positioned at an oblique angle with respect to the near display. The stimulus target displayed on the far display can be axially aligned with the stimulus target projected onto the first beam splitter. The method can also comprise obtaining, at a controller, measurements concerning refractive states of the eye during the first duration and the second duration from a refractor device in communication with the controller and determining, using the controller, an accommodative response of the eye based in part on the respective refractive states.
