Currently, about 55% of the civilian pilots in the United States
must utilize some form of refractive correction to meet the vision
requirements for medical certifi cation. While spectacles are the most
common choice for aviators, recent studies show a growing number
of pilots have opted for refractive surgical procedures, which include
laser refractive surgery. The information in this brochure describes
the benefi ts as well as possible pitfalls laser refractive surgery offers
to those considering these procedures.


What is Refractive Error?
Refractive error prevents light rays from being brought to a single
focus on the retina resulting in reduced visual acuity. To see clearly,
refractive errors are most often corrected with ophthalmic lenses
(glasses, contact lenses). The three principal types of refractive
conditions are myopia, hyperopia, and astigmatism. Another
ophthalmic condition that also results in blurred near vision is called
presbyopia. Presbyopia is a progressive loss of accommodation
(decreased ability to focus at near distance due to physiological
changes in the eye s crystalline lens) that normally occurs around 40
years of age. Bifocals or reading glasses are necessary to correct this
condition.
