Eye is an important organ of our body. It is a visionary organ which is able to visualize the things and to detect the objects. Eye is one of the five sensory organs of the human body. The other four are ear, nose, tongue and skins. The eye is a delicate and sensitive organ comprised of many components. The internal parts of an eye include the retina, cornea, iris, pupil, sclera, and optic nerve. The external parts include the eyelid, lashes, tear ducts and surrounding tissues. Eye is very sensitive to sunlight, flash lights, dusts, smokes, fire and heat. Eyes close spontaneously when it is exposed to these things.
Like any other organs of human body, visionary organ too are vulnerable to many infections and disorders. One of the most common eye disorders is shortsightedness or Myopia. In medical words, Myopia can be defined as a vision condition in which close objects are seen clearly, but objects farther away appear blurred. This condition affects millions of people across the world. While this condition has no age bar, this can occur in small kids to aged people as well. This is commonly caused due to increase in axial length of eyes or because of increased curvature of refractive surface of the eye. Eye doctors fix these problems using lenses such as external glasses or contact lenses. Wearing glasses is uncomfortable for many people. They feel discomfort in wearing it all the time. Such people can go for contact lenses. Contact lenses are small thin lens placed directly on the surface of the eye. But they need to be changed after the prescribed intervals of time.
The people who do not want to use either spectacles or contact lenses can go for eye surgery to get their visionary problems fixed. One of the most commonly carried out eye surgery for shortsightedness is the laser surgery. This is also called LASIK (Laser-Assisted in situ Keratomileusis). This is carried out by an experienced ophthalmologist. In this, eye's cornea is reshaped to improve the vision of the person. LASIK is a big sigh of relief for people who are fed up using contact lenses or eyeglasses. Since the success rate of this surgery is very high, it has now become the most wanted eyesight correction treatment all over the world.
Cataract Eye surgery is another major types of eye surgeries. Cloudiness on the lens of eye is called as cataract. Because of this transparency of eyes decreases and light does not pass through. This cloudiness or opacity of lens occurs mainly due to aging. With the help of cataract surgery this problem is treated.
While going for any kind of eye surgery, you need to carefully select a right surgeon or ophthalmologist who has experience in this surgery and treatment. The eye hospital you choose should have all the required infrastructure and medical facilities in place.
