Introduction to hypersonic vitrectomy
Current Opinion in Ophthalmology, 2019To review the development of hypersonic vitrectomy and present the first case series in the United States.From 27 September 2017 to 4 December 2017, 64 patients underwent hypersonic vitrectomy with 20 patients having conventional 23-ga vitrectomy for comparison.

Under conditions of high speed and gas rarefaction the character of the wake behind a body changes significantly from its behavior at normal densities. Experimental studies at M ≃ 6 and 8 with spheres and cylinders have clearly established the transition from the shock-expansion-neck-recompression type of wake to a completely merged type of flow field.

An experimental investigation was made of the flow field behind a two-dimensional circular cylinder at a nominal Mach number of 5.7. The free-stream Reynolds number based on the cylinder diameter was varied over a range from 4300 to 66, 500 by changing both the diameter of the cylinder and the stagnation pressure of the wind tunnel.

Abstract The chapter starts its analysis with blunt-nosed bodies. In a supersonic flow, a blunt-nosed body produces a bow shock wave. The chapter shows that the shape of the shock and the entire flow between the shock and the body become independent of the Mach number, M∞, provided it is large enough.
