Cornea LASIK Eye Surgery

LASIK eye surgery becomes permanently visible, depending on the size of the allocation of the power of the reshaping of excimer laser corneal surface with light. So in our view the cornea of the eye surgery, LASIK, the destination section and the simplicity of its structure and function.
The eye of the cornea is the clear crystal accessories section. The clock, Crystal, such as the cornea, a clear window to give us. It is about 1/2 mm thick (550 ± 50 micrometer) and five separate layers.
The cornea receives food, oxygen, minerals and glucose in the small vessels in the form of the outermost edge of the cornea, aqueous humor and sustainable, in parallel with the film. Nerve terminals resulting, therefore, very sensitive tissues, which is very painful, if disturbed, they also offer a full range of cornea, supplied by the cornea.

Epithelium
Corneal epithelium the outermost layer of the cornea has cells in the epithelial cells layers and consist of five to six. It provides a smooth optical surface of the barrier against infection and prevent access to the cornea of contaminants, bacteria, etc. The powers of the Epithelial cells again quickly, when the cornea is injured. However, if the damage penetrates into the cornea in the wake of enlargement, it may leave a scar. Opaque areas, leave scars cause to lose its luster and clarity of the cornea. Bowman layer
Below is the epithelium, Bowman's layer of the structure of the cell freely, which consists of a single collagen lämmöksi. Because this level is very hard and difficult to reach, it protects the cornea damage. This layer is unable to recover when the cornea is injured. Stroma
Corneal stroma in bulk is called, which consists of a single Republic in the Lao People's Democratic Republic and regularly arranged in bundles of collagen and lämmöksi together with the complex material is glued to the ground and air a few cells. Excimer laser eye surgery LASIK will remove some of the tissues of the cornea, this part of the cornea, so that the income support. Descemet membrane
Below is a list of the stroma is Descemet's membrane filters, cell free, strong, elastic Membrane filters in the corneal Endothelium, basement membrane filters. It grows throughout the entire life and turns slightly thicker advanced age. Endothelium
The cells of the endothelium is one layer of the cornea, which removes fluid. Aging, inflammation, the endothelial cells due to trauma. Endothelial cells to die and disappear, and the endothelial cells of the thin is distributed between the endothelial cell, lost count. Epithelium has other keratinized (absence of keratin protein is called) Stroma collagen fibres are organized on a regular basis, and packaged Tear film abolishes all the surfaces of the irregularities is the cornea Corneal nerves absence (the myelin is an insulating materials by electronic means) of the myelin sheath are blood vessels Corneal dried , maintained by the Endothelium
In addition, you can protect the delicate structures within the cornea to the eye, to help focus the light rays, create an image of the retina. Its manufacture is similar to the passage of light to create the image on the film Camera lens.
