Abstract

An electronic intraocular device is implantable into the capsular bag of a wearer's eye. In some cases, the intraocular device may include a femtoprojector. The femtoprojector projects images onto the wearer's retina when the electronic intraocular device is implanted in the wearer's eye. Different haptic designs may be used to keep the femtoprojector in position. In some embodiments, an imager is contained in a contact lens worn by the wearer. Images captured by the contact lens imager may be relayed to the intraocular femtoprojector. In some cases, the intraocular device may include an electronic capsular tension ring with a femtoimager. The femtoimager may capture images of the wearer's retina, for example for purposes of monitoring eye health.

Claims15

Dependent claims

A system for compensating corneal opacity of a patient, the system comprising:

a contact lens mountable on the patient's eye, the contact lens containing a camera that captures images of a patient's external environment;
an implantable intraocular device comprising a femtoprojector, wherein the intraocular device is insertable into a capsular bag of the patient's eye and the femtoprojector is positioned to project images onto the patient's retina when the intraocular device is implanted in the patient's eye;
and
a signal path from the camera to the femtoprojector, for processing and transmitting images captured by the camera for projection by the femtoprojector;
wherein the contact lens further contains an infrared transmitter, the intraocular device comprises an infrared receiver;
and the signal path includes the infrared transmitter, the infrared receiver, and wireless transmission from the infrared transmitter to the infrared receiver.
