According to The American Optometric Association astigmatism defines as a condition of the eyes that causes blurred vision. Several reasons exist why the condition occurs, but most are due to the irregular shape of the cornea which is the transparent covering of the eye. The other reason is the curve of the lens in the eye itself is not set where the light will converge on the retina as intended. At any distance near or far the vision blurs.
Common
Astigmatism occurs in most people to some degree due to the natural variations in genetics. It does not affect vision until it becomes a large amount. Termed refractive errors as the astigmatism increases the light bends differently. An exam by a professional optometrist can find the condition.
Treatment options
Treatment of astigmatism depends on its degree. Doctors prescribe glasses and contacts for the condition which simply alters the way light comes into the eye. Anyone who has used glasses knows that keeping up with a pair can prove frustrating. Contact lenses are a good option. The cost is expensive along with the daily routine and the maintenance with liquid solutions. A corneal procedure known as orthokeratology modifies the cornea. It involves a series of rigid contact lenses designed to reshape the curve of the cornea. Last but not least is LASIK laser eye surgery.
Wavefront laser vision correction
Wavefront digital technology came about because of astrophysics. Designed to reduce atmospheric distortions when viewing objects in the distance in space through telescopes, the technology soon found application in dealing with aberrations of the eyes. Wavefront LASIK maps the visual imperfections precisely for each patient more so than standard LASIK techniques. These precise measurements then transfer into an ablation profile. Technology known as variable spot sizes remove corneal tissue with the instrument called a laser excimer or the optometrist may use scanning spot technology. This reduces the halos and the glares the astigmatism causes.
The facts
– As time has passed and Wavefront guided LASIK has been applied the following potentials have been noted:
– A reduction in night vision disturbances
– A reduction in losing visual quality
– A reduction in contrast sensitivity
– More chance of attaining 20/20 vision without any glasses
Wavefront guided LASIK correction of myopic astigmatism in a clinical trial showed a 93.5% success rate with 20/20 vision attained within a 3-month period. A FDA clinical trial using VISX CustomVue wavefront technology four 94% of the patients had 20/20 vision. The patients were extremely satisfied with their night vision.
