Is Lasik in your future? Millions of Americans turn to Lasik Surgery when their vision is less than perfect and they’re tired of being tied down to wearing glasses or contacts. What part of the eye is it that may be causing all your vision trouble? Your cornea! When the shape of your cornea is irregular, the image on your retina is blurry and out-of-focus. The cornea is a part of your eye that works to focus light and projects an image on the retina. This focusing of light is called refraction. The 3 main types of refractive errors are myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. If you are nearsighted, you have trouble seeing distant objects. If you are farsighted, you have trouble seeing things close up.?Astigmatism is caused by irregularities in the surface of the cornea or lens and causes the image on the retina to be distorted. It’s not uncommon for a person to have a combination of all 3 refractive errors, myopia, hyperopia and astigmatism. Before Lasik Surgery, glasses and contact lenses were the main ways to compensate for your eye’s imperfections.
What exactly is Lasik? Lasik stands for Laser-Assisted In Situ Keratomileusis. Keratomileusis is the carving of the cornea in order to reshape it. As the laser reshapes the cornea, it changes the angle at which you see images and therefore strengthens your vision significantly. This reshaping adjusts and strengthens the power of your cornea to focus on objects near and far. If you are nearsighted, your doctor uses the laser to flatten your cornea that is too-steep. If you are farsighted, your doctor uses the laser to make your cornea steeper because it is too flat. For astigmatism, the laser can be used to smooth an irregular cornea into a more smooth shape. There are few other procedures like Lasik Eye Surgery that can give you these amazing results and permanently change the shape of your cornea in just minutes. OK, I’m convinced, now what? Start by talking to family, friends and co-workers.

Preparing For Laser Eye Surgery
Laser eye surgery can be for refractive and no refractive conditions of the eye. Many people believe that this form of eye surgery is specifically for one’s vision improvement but it can actually be used for other purposes. Laser eye surgery uses state of the art laser technology to help the individual with his or her eye problems. Fear of any form of surgery can be one of the reasons why some people hesitate to undergo laser eye surgery. Laser eye surgery cost can also hinder the procedure, since the cost may be monumental for some people.
Diagnosis Before Laser Eye Surgery
Before any form of laser eye surgery can be done to any individual, a diagnosis and consultation with a qualified doctor needs to be undertaken. These precautions are necessary to help the doctor and the individual come to a satisfactory solution to the eye problems of the patient. An ophthalmologist is the person whom the patient needs to see for any surgical procedure concerning the eyes. Laser eye surgery is just one of the many different kinds of procedures that an ophthalmologist may be able to do.
When the ophthalmologist and patient have reached an agreement, the preparations for laser eye surgery may then commence. Preparing the eyes for laser eye surgery can take up to several weeks. The use of contact lenses or glasses may be discouraged by the ophthalmologist a week or a few days prior to the laser eye surgery.
Before the actual laser eye surgery, local anesthesia is used to help the individual with any pain problems during and a little while after the procedure. General anesthesia may be used for the laser eye surgery if the patient is feeling apprehensive or if the patient is a child, prone to fidgeting and moving. Other preparations for laser eye surgery are to sterilize the area around the eye for safety and health purposes. Measurements of one’s eye before the operation will be taken by the ophthalmologists for the laser to be able to function properly.
Time duration for the actual laser eye surgery is just a few seconds to a little above a minute. The preparation can actually be the lengthier time compared to the procedure. Full recovery from laser eye surgery may take some time, from a week to several weeks, depending on what the procedure was all about. The eyes can be used after just a few days with the use of eye drops to facilitate healing.
