Question

Name the allotropic form of carbon which is used:

for removal of cataract

Answer 1

• As diamond is hard in nature and can be cut to pointed edges, eye surgeons use diamond to remove the cataract.
• Cataract is a condition of the eye where a layer of protein builds on the lens of the eye and is responsible for blurred vision.
• The property of an element due to which it exists in different physical forms which have identical chemical properties but different physical properties are called allotropy. The different physical forms of that element are called allotropes.
• Example: Carbon is an element that shows the property of allotropy because it exists in different physical forms that have identical chemical properties but different physical properties.

Therefore, diamond is used for the removal of the cataract.
