| Lasik maybe safer than contact lenses : |
|
 |
|
Researchers who reviewed several studies of complications from both contact lenses and Lasik surgery have concluded that Lasik is the safer option, in the long run.
Contact lens wearers have approximately a 1 in 100 (1.0%) risk of developing a serious contact lens-related eye infection over 30 years of use.
They also have about a 1 in 2,000 (0.05%) chance of significant vision loss as a result of a contact lens-related eye infection over the same period.

|
|
Of course, like any surgery, Lasik has its risks. But they calculated the risk of significant loss of vision at 1 in 10,000 (0.01%).
The researchers concluded that almost all contact lens wearers suffer some form of infection or eye allergy related to the contact lens material or cleaning solutions over 10 years of wear, even if the proper lens wear and lens care guidelines are followed.
The Medical Journal of Australia has also reported that coloured and novelty contact lenses lead to unsafe practices such as wearing lenses overnight, sharing of lenses, and poor lens hygiene.
Contact lens wearers should have an assessment to see if Lasik is the better option for them.

| A Lancet study showed that people who wear daily contact lenses run the risk of 1 in 100 of developing a bacterial keratitis, an infection of the cornea. Patients who abuse contacts by wearing them overnight or improperly caring for their lenses have an even larger risk. |

| NASA: LASIK & PRK Safe for Astronauts |
|
 |
|
People looking for reassurance that LASIK is safe may be comforted to know that NASA has now given its stamp of approval for these laser vision correction procedures.
NASA has announced that Astronauts are now permitted to improve their vision with laser eye surgery procedures including, wavefront-guided LASIK .
|
|
|
Previously around half of all rejected NASA Astronaut candidates were ruled out because of poor vision due to the need for glasses or contact lenses.
LASIK , more commonly called laser eye surgery, is a safe and popular choice for those people seeking freedom from visual hardware. The laser vision correction procedures are performed to eliminate or reduce the need for glasses or contact lenses for those candidates who are suitable. |

The eye works very much like a camera, with two lenses that focus light onto the retina. LASIK improves vision by reshaping the cornea (clear front window of the eye) to focus light onto the retina (light sensitive tissue lining the back of the eye, like a film in a camera).
The VISX STAR4 IR Laser system is the Laser technology that has approval for Laser Vision correction by NASA. |

Study confirms - LASIK safe and effective procedure in the long-term
ELSEVIER http://www.elsevier.com/
The American Journal of Ophthalmology recently published an article discussing results of a study of high myopia patients ten years after LASIK surgery. An overview of the article appears on the Elsevier website: titled "LASIK Works Well, According to Long-Term Study of Highly Myopic Patients". |
|
|
| According to lead investigator Jorge L. Alió, “These results are extremely encouraging considering that this refractive correction implies the maximum limit of application of this technique. This study has allowed us to demonstrate that, the results regarding predictability, efficacy and safety for high myopic patients are very good in the long term. The optimum limit of predictability for this technique is around 12 D of myopia. This reference study, with a long time perspective, allows us to know the safety, precision and limits of LASIK in highly myopic eyes. |

| US Army/Navy approve of Lasik for Pilots and Marines. |

Chris Amos - Staff writer for the US navy Times writes in a article that the United States Navy is providing up to 70,000 sailors and marines with free Lasik vision correction since October 2007.
Administrative approval has been given to Navy and Marine Pilots to undergo Lasik. In the past,

|
|
| Lasik was considered a risk due to the extreme conditions that pilots work under, including gravitational forces, low oxygen levels, wind blasts and dry air. Studies have now shown Lasik to be stable in all these conditions.Read the complete article at http://www.navytimes.com/news/2007 |
