TL;DR: In this article, a new electrical stimulation strategy is proposed using ultrasound-driven wireless energy harvesting technology to convert acoustic energy to electricity through the piezoelectric effect, and the design, fabrication, and performance of a millimeter-scale flexible ultrasound patch that utilizes an environment-friendly lead-free piezocomposite are described.

TL;DR: Challenges faced by retinal prosthesis are reviewed and potential solutions to address them are discussed.

TL;DR: A micro check valve as mentioned in this paper is a free-floating member for controlling flow of fluid in microfluidic and biomedical applications and methods of fabrication, which can be configured to allow fluid to flow when the floating member is pushed by fluid against the valve cap or against a valve seat.

TL;DR: Although a number of factors influence flow, the high and relatively constant vitreous flow rates of the new-generation cutters are most likely due to their maintenance of high duty cycle as cut speed increases.

TL;DR: In this article, a handheld, portable, and surgical intraocular illumination system is described that is disposable, low-cost, and efficient, where a surgeon can have direct control of turning the illuminator on and off and adjusting the intensity via a simple control ergonomically placed on the handpiece or voice activated control.
