What is astigmatism?
Astigmatism is a common vision problem. Usually, it is caused by an irregularly shaped cornea. Sometimes it's the result of an irregularly shaped lens. Either kind can potentially be corrected with laser vision correction.
What causes astigmatism?
Normal eyes are spherical, or shaped like a baseball. Astigmatic eyes are oblong, or shaped like a football. When the eye is shaped like a football, the cornea has a steeper and a flatter curve. The football-shaped astigmatic eye causes light rays to focus on two points in the back of the eye rather than one as in a normal eye.
I thought astigmatism could not be treated with laser vision correction?
Astigmatism can be treated with laser vision correction. The CustomVue procedure has been approved by the FDA to treat all forms of astigmatism, whether the astigmatism is associated with nearsightedness, farsightedness, or mixed astigmatism.
What is laser vision correction?
Laser vision correction is a procedure that improves vision by changing the shape of the cornea with a laser. Often referred to as LASIK (an acronym for the medical term laser assisted in-situ keratomileusis), it is the most commonly performed type of laser vision correction procedure and is an effective treatment for a wide range of vision problems.
How does the laser know what to correct in my eyes?
Laser vision correction is based on a precise wavefront measurement taken with a powerful measurement instrument known as the WaveScan WaveFront™ System. These measurements are used to design the individualized treatment which is then transferred to the laser.
How accurate is the WaveScan™ technology?
WaveScan technology measures imperfections in an individual's vision 25 times more precisely than the standard methods used for glasses and contact lenses.
What is CustomVue laser vision correction?
CustomVue is an individualized laser vision correction procedure that enables a doctor to design an individualized treatment for their patient's condition by measuring the unique imperfections in a patient's eye.
