What can be said about our eyes apart from the fact that they are the most valuable part of us. It is the vision of eyes that allows us to be grateful for the life around us. The power which God has vested in our eyes is the ability to view the uniqueness of our world. Sadly, many of the people are not gifted with good vision and have eye defects wherein they cannot see without the help of spectacles and lenses. Lasik or Eye Laser surgery has definitely changed the face of eye operations and has provided a great option to people with eye defects to see the world through their own eyes.
Lasik surgery has generated hype as it can be used to correct eye defects such as myopia, hyperopia and astigmatism. Lasik (laser-assisted in situ keratomileusis) is one of the types of refractive surgery and can be carried out only by skilled eye surgeons by using laser rays. Lasik is a kind of photorefractive keratectomy.
The popularity of Lasik can mainly be attributed to the lack of pain during and after the surgery which certainly encourages a good number of the patients to try out the procedure. Also, the procedure delivers fast results as in the patient receives good vision immediately from the very next day which encourages persons having vision problems to try out.
Lasik is only performed after the careful observation of the thickness of the cornea of the patient. The surgery involves making an incision onto the cornea to produce a thin flap which is performed by the microkeratome. However, nowadays, laser is also used to achieve the same.
Excimer laser is used to adjust the shape of cornea by removing the required amount of corneal tissues, subsequent to the cornea flap being pulled back. Ultraviolet rays of the excimer laser does the job of reshaping the cornea for normal vision.
A patient can get a good vision only after the cornea is reformed wherein the light rays will precisely fall on the retina wall. The corneal flap which was created during the surgery is returned to the place of corneal tissues which were earlier taken out.
Nearsighted, farsighted and people suffering from astigmatism can take advantage of the procedure. In nearsighted people, the steepness of the cornea is reduced near normalcy whereas in farsighted people the cornea is tried to be made steeper. Astigmatism correction is also possible by using excimer laser wherein the irregular cornea is brought to the normal shape.
The eye doctor who is performing the surgery will certainly give a detailed check-up of your eyes in order to estimate its health. He/she needs to analyze the condition of your eyes, the vision correction you really need and the quantity of laser ablation required to correct your vision. Every eye surgeon before starting the operation will search for dryness in the eyes of the patient. Even if it is not present, the patient should take great care of their eyes after the surgery in order to avoid dryness.
Lasik surgery is a very simple procedure and does not even take five minutes to complete and there is practically no pain. Some of the people regain your normal vision from the very first day but for some people it takes a couple of weeks more. Lasik surgery is the perfect route for people with eye defects to throw away their spectacles and gives them this amazing opportunity to view the world through their very eyes.
M. D. Stallworth published a significant number of articles on Lasik and several other methods of eye operations. He is especially interested in particular technological facets of eye laser, or Augenlaser as it is named in German, that are utilized in those procedures.
