How Astigmatism Lasers Work
Astigmatism is a common eye condition that causes blurred vision. It occurs when the cornea or lens of the eye is not perfectly round, causing light to focus at different points on the retina. This results in distorted or blurry vision.
Astigmatism lasers work by reshaping the cornea so that light can focus correctly on the retina. This is done by using a laser to remove a small amount of tissue from the cornea, which changes its shape and allows light to focus properly.
There are two main types of astigmatism lasers: excimer lasers and femtosecond lasers.
* Excimer lasers are the most common type of astigmatism laser. They use ultraviolet light to remove tissue from the cornea.
* Femtosecond lasers are newer than excimer lasers and use infrared light to remove tissue from the cornea. They are more precise than excimer lasers and can be used to treat a wider range of astigmatism.
Which type of astigmatism laser is best for me?
The best type of astigmatism laser for you will depend on your individual needs and preferences. Your doctor will recommend the best option for you based on the severity of your astigmatism, the shape of your cornea, and your overall eye health.
What are the risks of astigmatism laser surgery?
As with any type of surgery, there are some risks associated with astigmatism laser surgery. These risks include:
* Dry eye
* Glare
* Halos
* Starbursts
* Loss of vision
However, these risks are relatively rare and most people who undergo astigmatism laser surgery experience significant improvements in their vision.
What is the recovery time from astigmatism laser surgery?
The recovery time from astigmatism laser surgery varies from person to person. Most people experience some discomfort for the first few days after surgery, but this usually resolves quickly. You may also need to wear protective eye shields for a few days after surgery.
It is important to follow your doctor's instructions carefully during the recovery period to ensure the best possible outcome.
Am I a good candidate for astigmatism laser surgery?
If you have astigmatism and are interested in laser surgery, talk to your doctor to see if you are a good candidate. Astigmatism laser surgery is not right for everyone, but it may be a good option for you if you:
* Are at least 18 years old
* Have healthy eyes
* Have stable vision
* Are not pregnant or breastfeeding
Your doctor will be able to determine if you are a good candidate for astigmatism laser surgery and will discuss the risks and benefits of the procedure with you.
