Astigmatism is a common refractive error caused by an asymmetrically shaped cornea. A non-astigmatic cornea is round, while astigmatism causes a more oblong shape. The oblong asymmetry in your cornea prevents light from focusing on your retina, which leads to blurry or distorted vision at any distance.
Some astigmatism, but not most, can change over time, becoming more or less severe. Like other refractive errors, astigmatism can range in severity, but it doesn’t put your vision or eyesight at risk.
Unlike nearsightedness and farsightedness, you might not notice that astigmatism is affecting your vision. Some of the most common warning signs of astigmatism include headaches, eyestrain, and squinting.
Advanced Laser & Eye Center of Arizona diagnoses astigmatism during comprehensive eye exams. The doctors use tests to evaluate your visual acuity, such as asking you to read a series of letters off of a Snellen eye chart. They also use analog and digital keratometers to measure the curvature of your cornea.
Your doctor can also identify astigmatism during refraction. Refraction is the process of fine-tuning your prescription. As you look through a device, your doctor changes the lenses and asks which option is more clear.
You have many options to correct astigmatism. Your doctor at Advanced Laser & Eye Center of Arizona explains all of your options and answers your questions so you can make the best choice for your vision and lifestyle. Your options include:
The lenses to correct astigmatism have a special cylindrical lens prescription that compensates for the asymmetric curve of your cornea. It provides additional corrective power to specific parts of your lenses to give the clearest possible vision.
Depending on the severity of your astigmatism, your doctor might recommend toric contact lenses. Toric lenses have different corrective powers at different parts of the lens and are slightly weighted to keep them in the correct position on your eye. Additionally, gas permeable lenses maintain their shape while on your eye, which allows them to compensate for corneal asymmetry.
Advanced Laser & Eye Center of Arizona also offers state-of-the-art laser eye surgeries. Depending on the severity of your astigmatism, you might be able to correct your vision with a laser procedure such as LASIK or PRK to reshape your cornea, or a LESA ™ procedure to eliminate it permanently.
