What is Astigmatism? Astigmatism is
a refractive error that occurs when the curvature
of the cornea is egg-shaped instead of spherical
shaped. This prevents the light to focus onto the
retina and thus it is not refracted properly.

Types of Astigmatism Corneal Astigmatism- When
the cornea of your eye is distorted and creates
problem in clear vision it is called corneal
astigmatism. Lenticular Astigmatism- When the
distortion is caused in the lens of the eye, it
is called lenticular astigmatism. Causes of
Astigmatism Genetics is a very big factor that
causes Astigmatism. Most people are born with
it. Although very rare, Astigmatism is sometimes
caused by keratoconus, a condition that thins and
changes the curvature of the cornea.

How to treat Astigmatism? There are several
methods that your ophthalmologist may use to
correct astigmatism in your eyes Eye Glasses
Contact Lenses- This is the easiest way to
correct astigmatism. Eyeglasses help light to
refract properly providing you clear
vision. Similar to eye glasses, contact lenses
compensate for the uneven shape of the eye
thereby correcting your refractive
error. Orthokeratology- This is a temporary
process to treat astigmatism where one wears
rigid contact lenses during the night and may
remove it during the day. Implanted Lenses- It
is a surgery treatment wherein your eyes
deformed lens are replaced with other lens that
helps correct the shape of your eyes
cornea. Refractive Eye Surgery- There are
multiple eye surgeries such as Bladeless Lasik
Eye Surgery, Contoura Vision Lasik Surgery, SMILE
Laser Eye Surgery Aspheric Lasik. These
surgeries help treat refractive disorders such as
Astigmatism, Myopia and Hyperopia.
