Astigmatism is a condition that results in blurred vision and is caused when your cornea is misshapen. In a normal eye, the cornea is perfectly round like a baseball. In people with astigmatism, the cornea has an irregular shape, more like a football. The irregular shape means the light rays entering your eye can’t focus at a single point, which causes distorted vision. Most of the people who have hyperopia and myopia have some level of astigmatism.
Astigmatism isn’t always pronounced enough to require corrective action, but when it is, LASIK is one of the treatments used. The goal with astigmatism surgery is to reshape the surface of your eye, so it is rounded like a normal eye. During the procedure, a corneal flap is created and an excimer laser is used to reshape the cornea.
Some symptoms of astigmatism include blurred vision at distances and up close, headaches, eye strain and squinting when trying to focus. If you notice that symptoms of astigmatism are affecting your day-to-day activities, schedule an appointment for a free consultation.
