Wireless power and data transmission system for a micro implantable intraocular vision aid

Area of Science:

• Biomedical Engineering
• Ophthalmology
• Wireless Communication

Background:

• Bilateral corneal opacification causes blindness in patients with intact posterior ocular structures.
• Existing vision aids often require uncomfortable mechanical wiring or lack wireless capabilities.
• A need exists for advanced intraocular devices offering seamless wireless power and data transmission.

Purpose of the Study:

• To describe a novel wireless power and data transmission system for an intraocular vision aid.
• To enable vision restoration for patients with specific types of blindness.
• To provide a comfortable and effective solution through an implantable device.

Main Methods:

• Development of an external unit for image acquisition, coding, and wireless transmission.
• Design of an implantable unit with a CMOS receiver, antenna coil, and LED microdisplay.
• Utilized a 13.56 MHz RF link for wireless power transmission.
• Employed a near-infrared (NIR) optical link for wireless data transmission.

Main Results:

• Successfully demonstrated a functional wireless system for intraocular vision aid.
• Integrated wireless power and data transfer, eliminating the need for mechanical wiring.
• The system is suitable for patients with bilateral corneal opacification and healthy retinas.

Conclusions:

• The described wireless system offers an optimal technical solution for intraocular vision aids.
• This technology has the potential to significantly improve the quality of life for visually impaired patients.
• Further development could lead to more advanced and widely accessible vision restoration technologies.
