CRYOEXTRACTION

In ophthalmology, 'cryoextraction' is a form of intracapsular cataract extraction in which a special medical instrument, a cryoprobe, is used to freeze the crystalline lens and pull it intact from the eye. Dr. Charles Kelman is credited with pioneering this surgical method in 1962.

'Cryoextraction' is the process by which grapes are frozen with refrigeration and pressed.
Winemakers subject grapes to temperatures around 20 degrees Fahrenheit (or -7 degrees Celsius), and press them while still frozen. Ice crystals remain in the press, while concentrated juice flows out. The resulting wine resembles ice wine.
The process of ''freeze distillation'' is similar in its concentrating effects, although it occurs after fermentation.
