Laser eye treatment is a high tech yet simple surgical procedure to permanently repair and restore 20/20 vision. The reason for most eye problems is that the eye lens cannot focus light rays properly onto the retina where the image is formed. In most cases, this is because the cornea is not perfectly shaped. The cornea is that part of the eye that focuses light and creates images on the retina. When it is misshapen, the improper focusing of light forms distorted images on the retina.
Reshaping Of The Eye Lens
In laser eye treatment the doctor uses a laser to scan the eye to find out as many different points on the cornea as possible. With the help of a computer program, he determines the irregularities in the cornea and the alterations required. A numbing medicine is introduced into the eyeball and then the surrounding areas are thoroughly cleaned. A device to keep the eyelid open is placed on the eye. The doctor pulls the cornea forward through a method of suction.
Different kinds of lasers are used in the operation. One laser helps to cut the clear membrane covering the front of the eyeball and another intense laser is used to open a flap in the cornea. This gives access into the eye lens. An intense beam is used to evaporate a portion of the lens to reshape it. After the surgery, a protective covering is provided to keep patients from rubbing the area, as there may be some itching and burning, which is normal. Patients should continue to follow the doctor’s instructions after the treatment. There are very few side effects of laser eye treatment. The possibility of the eye getting infected is also as rare as 1 in 5000 cases.
After treatment, due to its rectified shape the cornea can focus light rays properly on the retina and this results in better vision. Laser eye treatment is a relatively short procedure of less than thirty minutes that can be performed in the doctor's office itself.
Solution For All Eye Problems
Common eye problems like nearsightedness or myopia, farsightedness or hyperopia, and astigmatism occur due to improper focusing of light and can be rectified completely by laser eye treatment. This permanently relieves the patient of using spectacles and contact lenses. However, this treatment is not an effective and practical option for people under the age of eighteen. Some people have an eye condition called refractive instability in which the eye's ability to focus light keeps changing often. For such people also the treatment is not a practical option. Also, pregnant ladies should undergo this treatment only after child-birth as their fluctuating hormones, diabetes, or typical body conditions may prevent the healing process.
Laser eye treatment is a considerably affordable procedure for any adult to treat eyesight problems permanently.
