 Informative Article Summary by Anny Redperz
Vision correction using lasers have been used by the civilians for more than 5 years. Now NASA and U.S. military have increased the performance of mission-critical personnel using this laser treatment. An all-laser form of LASIK has been tapped by the Department of Defense(DoD) and NASA to improve the vision of specialized personnel who face extreme and physically demanding conditions. It has been validated that LASIK exceeds all standards of safety and effectiveness.
This modern LASIK which is also known as iLASIK procedure uses two lasers as opposed to one laser in the previous procedure. In the initial stage, the characteristics of the individual’s eyes are mapped using wave-front technology. Later a computer guided ultrafast laser is used to create a corneal flap. This laser replaces the microkeratome blade used in older techniques and this makes this safer. A second laser guides the vision correction using the wave-front mapping data. This combination of technologies provides excellent safety and visual results.
Results have shown that 95 % of personnel achieved 20/20 uncorrected vision or better and they recommend others to do the same and join the 12 million Americans who have benefited from LASIK.
Considering Lasik Surgery? Lasik Eye Surgery Can Improve Your Sight
Lasik Surgery is a surgery that is performed by Ophthalmologists. It is often painless and quick. The good thing is that the patient can go back to work with immediate effect after the Lasik Surgery is performed, sometimes as early as the next day. The ability of the surgeon combined with the high-level technology that is required for the surgery is what ensures that the operation is successfully performed and completed.
Many patients prefer Lasik Surgery and think that they would rather undergo a Lasik Surgery than wear glasses or contact lenses. The Lasik Surgery takes a pretty short time because of the uniqueness of the surgery. The surgery never takes more than eight to ten minutes. Since Lasik Surgery is Laser Surgery, it involves the burning of tissues. The laser gets to the tissue by burning the stroma and it does not take long for the eye to “recover” because unlike other surgeries, here the tissue is not “hurt” in any way.
Lasik Surgery is a quick procedure, it only takes about an hour– but patients are asked to take rest for longer. One must avoid the urge to scratch the eye during this time. The patient may have the propensity to do so because the eye is exceedingly irritable at this juncture. The patient must avoid plunging into swimming pools and other water sports that he/she might be interested in for a month. Dry eyes and Halo may be caused because of this process.
When you compare the Lasik Surgery to other kinds of surgeries, you understand that it is free from most of the trouble that most other surgeries cause. Still, it is advisable to take all the precautions that are necessary to avoid any infection or complications later on. The patient must not use any lotions or any make-up for about two days after the surgery as that might hamper the patient’s speed of recovery. Also, sports like Karate, Kick Boxing, and Taekwondo should be played only after complete recovery.
For a laser Eye surgery, one must choose his/her doctor very carefully. For a sensitive operation like this, it is very important to realize that one’s eye is one’s asset and one cannot afford to take any chances. While some doctors may perform the surgery at a cheaper cost, it is always better to go with a doctor who has experience and who has performed these surgeries successfully before.
Who benefits from a Lasik Surgery?
Anyone with poor eyesight benefits from Lasik Surgery. Since this is a refractive laser eye surgery, ophthalmologists use it to cure myopia, astigmatism, and hypermetropia. However, if not performed carefully the patient can suffer from substantial loss of contrast sensitivity.
The decision for a Lasik Surgery should be taken after consulting one’s doctor. After all, this is a risk of sorts and comes with its fair share of side effects. If none of the doctors you know have ever done Lasik Surgery (and this is possible because it is a fairly new kind of surgery), then it is best to go to a large and reputed clinic before you decide to go in for a Lasik Surgery.
In 2006, a study was done that concluded that contact wearers are at a greater risk for infection than individuals who have had Lasik eye surgery
