Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ophthalmologist. [1] The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return home.
Around the time of the construction of its predecessor, the Shiva laser, laser fusion had entered the realm of "big science". Inertial confinement fusion ( ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium ( 2 ...

Description. Littrow (optical) prisms typically have the shape of a (geometric) prism with a 30°/60°/90° right triangular base, [1] [2] equivalent to half an equilateral triangle. Typically, they are coated with a reflective film coating on the surface opposite the 60° angle. This design was devised by Otto von Littrow (1843—1864).
Viewfinder eyepiece. A digital single-lens reflex camera ( digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor. The reflex design scheme is the primary difference between a DSLR and other digital cameras.
A Wollaston prism is an optical device, invented by William Hyde Wollaston, that manipulates polarized light. It separates light into two separate linearly polarized outgoing beams with orthogonal polarization. [1] The two beams will be polarized according to the optical axis of the two right angle prisms. The Wollaston prism consists of two ...
Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. [ citation needed ] Laser science is principally concerned with quantum electronics , laser construction , optical cavity design, the physics of producing a population inversion in laser media , and the temporal evolution of the light field in ...
Minoxidil, applied topically, is widely used for the treatment of hair loss. It may be effective in helping promote hair growth in both men and women with androgenic alopecia. [20] [21] About 40% of men experience hair regrowth after 3–6 months. [22]
