Need: From 1 Different Sources

n. what is required rather than simply desired or wanted. In allocating limited health-care resources, clinical need is often defined as the capacity to benefit from an intervention and assessed on a utilitarian basis (see quality of life). Other conceptions of need, such as the state of requiring rescue from a life-threatening situation, are based on *deontology.

Needling

An operation performed in the treatment of cataracts (see under EYE, DISORDERS OF), in which the anterior lens capsule of the EYE is torn open with a needle, allowing the aqueous ?uid to dissolve the opaque soft lens matter, which is gradually washed away into the bloodstream. This ‘extra-capsular extraction’ may need to be repeated several times before all the opaque lens matter disperses. Although a relatively simple procedure, it is unsuitable for patients over the age of 35 (when the nucleus of the lens becomes increasingly hard), and CRYOSURGERY and LASER therapy have become the preferred methods of treatment.

Needling is also used for certain minor dermatological procedures, such as removal of small facial cysts and scabies mites.... needling
