Lens regeneration in situ using hESCs-derived cells —similar to natural lens
iScience, 2023 Summary: Lens itself has limited regeneration functionality, thus we aimed to create regenerated lens with biological function to treat cataracts rather than the intraocular lens used in cataract surgery.

Optimization of Zoom Lens with Discrete State of Liquid Lens Elements by Using Genetic Algorithm
Advances in Materials Science and Engineering, 2015 This paper is to employ liquid lens elements to design a lens with zoom function by using the genetic algorithm (GA) optimization. The liquid lens elements used in the proposal can apply voltage adjustment to generate the electrical field that induces ...
