If you have astigmatism, you might have considered laser eye surgery as a treatment option since it has a very high success rate for correcting other vision issues, such as nearsightedness and farsightedness. Astigmatism, a common vision problem caused by an irregularly shaped cornea or lens, leads to blurred or distorted vision. Fortunately, advancements in laser eye surgery offer precise and effective solutions for correcting astigmatism by reshaping the cornea.
But does laser eye surgery effectively treat astigmatism? What should you know about the procedure before proceeding? In this article, we will address all your queries, including how laser eye surgery can fix astigmatism, the types of laser procedures available, their benefits, and who can benefit from the surgery.
What is Astigmatism?
Astigmatism, a common vision problem caused by a faultiness in the curvature of the eye, leading to distorted or blurred vision. This condition occurs when the cornea, the clear front surface of the eye, or the lens inside the eye have an irregular shape. Instead of being symmetrically round, the cornea or lens is shaped more like a football, which prevents light from focusing correctly on the retina, resulting in blurred vision at all distances.
What are the different types of Astigmatism?
Astigmatism is categorized into two types:
- Corneal astigmatism: It occurs when the cornea has an irregular shape.
- Lenticular astigmatism: It occurs due to an irregularly shaped lens.
Both types of astigmatism cause the light entering the eye to scatter, leading to blurry vision.
What Are the Symptoms of Astigmatism?
Common symptoms of astigmatism include:
- Blurred or distorted vision
- Eyestrain, fatigue, or discomfort
- Headaches
- Difficulty seeing at night
- Squinting to see clearly
How Is Astigmatism Diagnosed?
Astigmatism can be diagnosed through a comprehensive eye examination that includes tests such as:
- Visual acuity testing
- Keratometry
- Corneal topography
- Slit lamp exam
- Refraction test
Is Correcting Astigmatism Worth It?
Addressing astigmatism symptoms depends on your personal preferences. If you are comfortable with glasses or contact lenses, these may continue to be suitable options for you. However, if you seek a more permanent solution, especially if your prescription deteriorates, then you should think of laser eye surgery for your astigmatism.
Can Laser Eye Surgery Correct Astigmatism?
Laser eye surgery is a popular and effective treatment option for correcting astigmatism. The two most common types of laser surgeries used to correct astigmatism are LASIK (Laser-Assisted In Situ Keratomileusis) and LASEK (Laser Epithelial Keratomileusis).
- LASIK (Laser-Assisted in Situ Keratomileusis)
LASIK is the most widely performed laser eye surgery and is highly effective for correcting astigmatism. During LASIK, an ophthalmologist creates a thin flap in the cornea using a microkeratome or femtosecond laser. The surgeon then folds back the flap to access the underlying cornea and reshapes it using an excimer laser. This reshaping allows light to focus correctly on the retina, resulting in clear vision. The flap is then repositioned to adhere naturally without the need for stitches. - LASEK (Laser Epithelial Keratomileusis)
LASEK (Laser Epithelial Keratomileusis) is a type of refractive surgery used to correct astigmatism. Unlike LASIK, LASEK doesn’t create a flap in the cornea but instead removes the thin outer layer (epithelium), reshaping the cornea underneath with a laser. The epithelium is then repositioned. This procedure aims to improve vision by correcting the cornea’s shape, reducing astigmatism, and enhancing visual clarity.
What Are the Advantages of Laser Eye Surgery for Astigmatism?
Laser eye surgery offers numerous benefits for individuals with astigmatism:
- Improved vision:Both LASIK and LASEK can significantly improve vision by correcting the irregular shape of the cornea, allowing light to focus correctly on the retina.
- High success rates:Laser eye surgeries have high success rates, with the majority of patients achieving 20/20 vision or better.
- Minimal discomfort:The procedures are performed under local anesthesia (eye drops), and most patients experience minimal discomfort during and after surgery.
- Quick procedure:Laser eye surgeries are relatively quick, usually taking about 15 to 30 minutes for both eyes.
- Rapid recovery:After undergoing laser eye surgery, numerous patients experience rapid visual recovery, witnessing notable enhancements in their vision within just a few days post-operation.
- Long-lasting results:Laser eye surgery provides long-lasting correction for astigmatism. Most patients enjoy improved vision for many years, reducing or eliminating the need for glasses or contact lenses.
Who is a Good Candidate for Laser Eye Surgery for Astigmatism?
Everyone is not a suitable candidate for laser eye surgery. Ideal candidates usually have the following characteristics:
- Stable vision for at least a year before surgery.
- Healthy eyes are free of diseases, infections, and severe dry eyes.
- Adequate corneal thickness.
- Should have realistic expectations.
- Most surgeons recommend that patients be at least 18 years old.
