1. An apparatus comprising:
- an intraocular lens having an index of refraction that varies in response to a focusing stimulus;
an actuator in communication with said lens for providing said focusing stimulus;
a rangefinder for generating a range estimate indicative of a relative distance to an object-of-regard; and
a controller coupled to said rangefinder and to said actuator for causing said actuator to generate a focusing stimulus on the basis of said range estimate.

Abstract
A vision prosthesis includes a lens having an index of refraction that varies in response to a focusing stimulus. An actuator in communication with the lens provides the focusing stimulus on the basis of a range estimate from a rangefinder. A controller coupled to the rangefinder and to the actuator causes the actuator to generate a focusing stimulus on the basis of the range estimate.

17. An apparatus comprising:
-
a intraocular lens having an index of refraction that varies in response to a focusing stimulus; an actuator in communication with said lens for providing said focusing stimulus; a rangefinder for generating a range estimate indicative of a relative distance to an object-of-regard, said rangefinder including a transducer for detecting a stimulus from an anatomic structure in an eye, said stimulus being indicative of a range to said object-of-regard; and a controller coupled to said rangefinder and to said actuator for causing said actuator to generate a focusing stimulus on the basis of said range estimate. - View Dependent Claims (18, 19)

20. An apparatus comprising:
-
an intraocular lens system having a focal length that varies in response to a focusing stimulus; an actuator in communication with the lens system for providing the focusing stimulus; a rangefinder for generating a range estimate indicative of a relative distance to an object-of-regard; and a controller coupled to the rangefinder and to the actuator for causing the actuator to generate the focusing stimulus on the basis of the range estimate. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
