Cornea Treatment in Pune
This is the outermost layer of the eye. Light enters the eye through the cornea. It is a transparent glass like structure. Transparency of the cornea is an important aspect of clear vision. The cornea measures 12mm horizontally and 11mm vertically. The cornea contributes 70 % of the total focusing power of the eye. This is the main reason it is important to take care of the cornea.
The change in the shape of the cornea may lead to development of refractive errors.
If the cornea is steeper than normal it cause myopia.
If the cornea is flatter than normal it cause hypermetropia.
If the cornea is irregular it will lead to astigmatism.
Structure of the Cornea
The cornea is made up of 5 layers each layer has its own function
Outermost layer of cornea is called epithelium. It is the protective layer. Every external object that enters the will go through the epithelium. The epithelium keeps shedding and regenerating its cells. The functions of epithelium are:
To protect the eye from dust, bacteria, water and other foreign bodies that may cause damage to the eye.
It absorbs oxygen and nutrients from the tears and keep the surface of the cornea smooth
This is the second layer of the cornea. It is also known as anterior limiting membrane. It is made up of protein fibres called collagen. It’s a strong layer between the corneal stroma and epithelium
This is the middle layer of the cornea. It is made up of collagen fibrils, water and keratocytes. There 200- 300 layers of collagen fibrils arranged in parallel fashion this is responsible for the transparency of the cornea.
It is the fourth layer of the cornea. It protects the eye from infections and injuries. It is referred to as posterior limiting membrane& consists of collagen fibrils.
It is the innermost layer of the cornea. It maintains the fluid balance in the cornea.
