Whilst eye drops may reduce the symptoms, the only curative therapy is surgery. Surgery is usually performed as day surgery under local anaesthetic. Almost always, you will also be given some sedation by the anaesthetist. Occasionally patients will have a full general anaesthetic.
In the Periodic table, potassium is one of seven elements in column (group) 1 (alkali metals): they all have a single valence electron in their outer electron shell, which they readily give up to create an atom with a positive charge-a cation, and combine with anions to form salts.he English name for the element potassium comes from the word  potash , and refers to the method by which potassium was obtained â placing in a pot the ash of burnt wood or tree leaves, adding water, heating, and evaporating the solution.
In the human body, potassium is an electrolyte (like sodium, but a larger molecule). It forms positively-charged ions in water solutions. Potassium is important in muscle control and the firing of neurons, as well as other cellular functions.
