Dynamic Pupil for ophthalmological applications

Country of Origin: Spain
Reference Number: TOES20200914001
Publication Date: 14 September 2020

Summary

Researchers from Spanish Research Institutions have recently developed a self‐regulating iris based on light‐actuated broadband absorber metamaterial. 

Manufacturing companies of contact lenses and/or ocular prosthesis are being sought to collaborate and/or exploit the existing know how through a patent license agreement.

Description

The development of dynamic pupils to solve ocular problems is until now a challenge to be solved. A novel technology based on an artificial dynamic iris, which adapts its size proportionally to the intensity of incident light, simulating the iris's real response, has been a very good approach to overcome this challenge. 
The developed artificial dynamic pupil, implemented in contact lenses or ocular prosthesis, would correct eye malfunctions or pupil problems due to ocular diseases such as aniridia, “adie” syndrome, anisocoria, and eye loss, among others.

Advantages and Innovations

The main advantages of the prototype developed are the following:

- Light actuated
- Battery free
- Biocompatible and adaptable to different polymers being suitable as ocular prosthesis and/or contact lenses.
- Broadband actuation (not only in the ultraviolet range).
- Shape easily to be customized.
- The application of magnetic fields is not required.
