Soldiers
wearing prescription lenses are usually become more problematic
with protective eyewear, due to the limited options and discomfort
associated with wearing goggles and glasses (contact lenses are
prohibited in theater). This problem has been solved partially,
with the use of 'optical inserts' with some of the protective
eyewear, however, these inserts may cause even more problems in
combat situations, even when they are worn with ballistic eyewear.
While the goggles themselves can survive an impact or even endure
an IED blast, if the optical insert is not designed to endure
the impact, it can shatter and cause even more damage, as it is
located closer to the eye.
For an increasing number of service members, laser eye surgery
is not a cosmetic nor convenience issue. It is all about saving
lives on the battlefield. The military has come a long way since
2000, when DoD first began allowing people with two common forms
of laser eye surgery to enter the military with a medical waiver.
People who had corrective eye surgery were previously ineligible
for military service. That move was based largely on groundwork
laid by the Navy. Naval Medical Center San Diego launched the
military's first refractive-surgery program in 1993, primarily
serving Navy SEALS who had problems losing contacts or eyeglasses
while parachuting or in the water.
Laser refractive surgery is now permitted for all warfare communities
within the Navy and Marine Corps. The Air Force Warfighter Photorefractive
Keratectomy Program went active at the end of 2001. The Army's
first Warfighter Refractive Eye Clinic, at Fort Bragg, opened
its doors in May 2000. The most common types of laser eye surgery
offered are photorefractive
keratectomy, or PRK, and laser in-situ keratomileusis, often
referred to as LASIK.
In the past some 80 percent of the patients chose PRK, a procedure
that requires a slightly longer healing time but poses reduced
risk of complication. In early November 2006 the US Navy allowed,
for the first time, to four of its aviators to undergo LASIK surgery
with the IntraLase method. lthough LASIK is not yet officially
approved in the U.S. military aviation community, this is a first
step in that direction. In the past, concern about the harsh aviation
environment has prevented the use of LASIK as a method to treat
the eyes of military pilots, Dr
Dello Russo explained. High altitude, dry air, and wind blast
are just some of the extreme conditions that these pilots encounter,
but years of LASIK trials on non-aviation personnel encouraged
the Bureau of Naval Medicine.
