It used to be people who have blurred or unclear vision has to use glasses as their visual aids. When a nearsighted level is getting bigger, the thickness of lens is getting bigger too. It is sometimes very disturbing and difficult for users. But now that suffering can be relieved by a surgical procedure called LASIK surgery. The popularity of LASIK surgery is growing over time. Now, the number of hospitals that can perform LASIK surgery process is growing fast.
LASIK is Laser-Assisted In Situ Keratomileusis, a procedure to correct blurred or unclear vision using a laser beam. In this article, I will invite you to get to know the benefits of Lasik surgery for the eyes. LASIK is a surgery that permanently changes the shape of the cornea to improve vision and reduce the dependence of people on the use of glasses or contact lenses. Lasik is very effective; it can be done quickly and safely.
To get clear vision, cornea and lens must be able to bend light so well that the image will be seen clearly on the retina. For information, improper bending of light will cause blurred vision. Haziness of vision is called refractive disorder. This disorder is caused by differences between the shapes of the cornea to the length of the eye. Any changes in the shape of the cornea will cause changes in human vision. The use of glasses is essentially the right to bend the rays on the retina. By reshaping the cornea, the light coming will automatically focused directly on the retina without tools though. Everyone needs to realize that the reshaping of the cornea is the core of any Lasik surgery.
Lasik uses ultraviolet laser beam to remove corneal tissue and give a new shape of the cornea so that light can be focused clearly on the retina. Lasik surgery causes the cornea becoming thinner. LASIK is a surgical procedure that is simple and does not need inpatient care for patients. This procedure only takes about 10 to 15 minutes. Drugs used just kind of eye drops that make the surface of the eye becoming numb. We already know that anesthesia is essential in any operation, not least in LASIK surgery. Anesthetic used in this operation is a local anesthetic that will not turn off the consciousness of the patient.
We need to know that the LASIK procedure is done while the patient is conscious. Each patient will be given a drug that gives a sense of comfort and minimize nervousness. LASIK can be done to one eye or both at once in a single session of the surgical procedure. Lasik surgery is one of the shortest surgeries ever undertaken by humans.
When the LASIK procedure is underway, a special automated knife or called mikrokeratome used for cutting eye tissue that interferes in the outer layer of the eyeball. Now this procedure has been widely known and using various types of lasers to shape the cornea eyelid. The petals are placed on the outside and a laser is used to reshape the corneal tissue that is located on the inside. Reshaping of the corneal tissue on the inside is at the core of Lasik surgery.
After the formation of the cornea is completed, then petals will be secured and the patient does not require stitches because the cornea will naturally hold the lids in place. Bandages will be placed outside the eyelids to protect their eyes from the hand rub or pressure until the condition is completely healthy again. Those are some things worth known of LASIK surgery for the eyes. The costs required to perform LASIK surgery is getting more affordable, since the quick widespread of availability of Lasik technology in various hospitals. LASIK is a permanent solution to eliminate your dependence on glasses and contact lenses.
