Electronic capsular tension ring

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.

AI Technical Summary

Benefits of technology

This patent is about electronic devices that can be implanted in the eye to restore sight. The technical effects of the patent include the use of femtoprojectors to bypass corneal opacity and the development of different image signal paths for systems using an eye-mounted femtoimager and intraocular femtoprojector. The patent also describes the advantages and features of the electronic intraocular devices, such as the use of flexible circuit boards and multiple femtoprojectors. Overall, the patent aims to provide a solution for restoring sight in cases of corneal opacity or injury.

Problems solved by technology

The pump sprayer he was using ruptured and sprayed disinfectant in his face, leaving him permanently blind in both eyes.

Other well-known causes of accidental blindness include battery acid burns suffered as a result of incorrect automobile jump starting technique and burns from playing with fireworks.

Diseases, burns and injuries to the cornea cause blindness if the cornea becomes opaque.

A cornea transplant can restore sight, but transplants depend on the availability of donor corneas and are not recommended in cases where the cornea has become vascularized as is often the case with chemical burns.
