Diamond enhancements are specific treatments, performed on natural diamonds (usually those already cut and polished into gems ), which are designed to improve the visual gemological characteristics of the diamond in one or more ways. These include clarity treatments such as laser drilling to remove black carbon inclusions, fracture filling to ...
Trabeculoplasty. Trabeculoplasty is a laser treatment for glaucoma. It is done on an argon laser equipped slit lamp, using a Goldmann gonioscope lens mirror. Specifically, an argon laser is used to improve drainage through the eye's trabecular meshwork, from which the aqueous humour drains. This helps reduce intraocular pressure caused by open ...
The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
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).
Fraxel. Fraxel Laser Treatment is a line of lasers developed by Reliant Technologies in 2004. It was developed from a US patent licensed from the Wellman Center for Photomedicine. R. Rox Anderson was the inventor. Fraxel lasers cause fractional photothermolysis for skin resurfacing. Complications observed in a study of 961 fractional laser ...
v. t. e. Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [1] but most recent research on it has been conducted in Germany (by UV lamps) and in Russia (in all variants).
Fat removal procedures are used mostly in cosmetic surgery with the intention of removing unwanted adipose tissue. The procedure may be invasive, as with liposuction, [1] or noninvasive using laser therapy, radiofrequency, ultrasound or cold ( cryoablation or cryolipolysis) to reduce fat, sometimes in combination with injections. [2] [3] Fat is ...
Prism (optics) An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides.
