Astigmatism is a common vision issue that causes blurred sight. It affects around 1 in 3 patients and the rate increases in patients 70 years or older. It happens when the cornea or lens is unevenly shaped, making light focus on multiple spots on the retina instead of one. This can result in distorted or blurry vision at any distance.
Many people ask themselves, "Can LASIK correct astigmatism?" At TVLC, we understand your concerns and want to help you find the best solution. Our skilled LASIK surgeons and eye doctors are here to answer your questions and guide you through the process.

In this article, we will look at how LASIK can correct astigmatism. We'll explain how the procedure works, what you can expect, and how it may enhance your vision. Join us as we explore if LASIK is the right option for you.
Astigmatism occurs when the cornea or lens is irregular, causing light to focus on multiple areas on the retina rather than precisely at one point. This discrepancy leads to distorted or blurry vision. Both hereditary factors and environmental conditions can play a role in the development of astigmatism.
Common symptoms include:
Astigmatism can be classified based on its origin and complexity, primarily into corneal, lenticular, or retinal types, as well as simple, compound, and mixed categories.
Each type of astigmatism affects vision differently, impacting clarity and focus on objects at various distances. Proper diagnosis and treatment are essential for effective management.
Diagnosing astigmatism usually requires comprehensive eye exams, including tests for vision sharpness and corneal topography to evaluate the cornea's shape and health. A study found that catching astigmatism early and correcting it with the right lenses or surgery can greatly improve vision, lessen symptoms, and prevent long-term effects such as lazy eye (amblyopia) and vision loss.
LASIK, or Laser-Assisted In Situ Keratomileusis, is a popular laser eye surgery designed to correct vision problems such as myopia, hyperopia, and astigmatism.
LASIK involves using a specialized laser to precisely reshape the cornea, improving the eye's focus. The procedure typically begins with the creation of a thin corneal flap, which is lifted to allow laser reshaping of the underlying corneal tissue. This minimally invasive technique results in quick recovery times and enhanced vision clarity.
The LASIK procedure starts with the surgeon making a thin flap in the cornea. This flap is lifted to access the tissue underneath, where a laser reshapes the cornea using precise measurements.
Reshaping the cornea is done by using an excimer laser to remove bits of tissue from its surface, correcting its shape. This helps light focus correctly on the retina, which can reduce or eliminate astigmatism. The laser's accuracy also protects nearby corneal tissue, leading to faster healing.
Research indicates that LASIK surgery is effective and reliable for achieving great vision without glasses, and it's safe with minimal risk of losing vision for people with low to moderate astigmatism under 2D. This makes LASIK a popular option for people living with astigmatism who want to improve their vision, lifestyle, and overall well-being.
LASIK surgery offers a multitude of advantages for individuals with astigmatism, addressing visual distortions and enhancing everyday life activities.
Understanding who qualifies for LASIK surgery to correct astigmatism is crucial for ensuring successful outcomes.
Candidates for LASIK to correct astigmatism generally include individuals over the age of 18 whose astigmatism is stable. The candidate's prescription must remain unchanged for at least one year to establish a baseline for effective treatment. Additionally, candidates should be in good overall health with no contraindicating medical conditions that might impair healing.
While LASIK can be performed on individuals as young as 18, the optimal age for the procedure tends to be between 25 and 40. Patients in this age range are more likely to have stable prescriptions and mature eyesight. Beyond 40, the onset of presbyopia may require additional considerations for vision correction.
Candidates must have healthy corneas for LASIK to be an effective and safe option. Conditions like keratoconus or severe dry eye syndrome may disqualify a patient from undergoing the surgery. An ophthalmologist will conduct a thorough eye exam to evaluate corneal thickness and surface health.
LASIK might not be suitable for everyone. Factors like autoimmune diseases, pregnancy, and certain medications that impact vision can make it unsuitable. Also, if patients have unrealistic expectations or expect major lifestyle changes that could alter their vision needs, they should look into other options.
When looking at options to correct astigmatism, patients can choose LASIK, glasses, contact lenses, or other surgical options like PRK and toric intraocular lenses. Each choice has its pros and cons, so it's important to understand them to make the best decision.
Glasses are a simple way to fix astigmatism, helping you see clearly by using custom lenses to adjust for cornea irregularities. However, they can be heavy during sports, can get lost or broken, and don't allow for a glasses-free lifestyle.
On the other hand, LASIK offers a permanent solution, eliminating the need for glasses and providing more convenience and freedom, especially for those who are active outdoors.
Contact lenses are a good alternative to glasses, giving clear vision and a better look without the hassle of frames. However, they need careful maintenance, can lead to eye infections, and might be uncomfortable if worn for too long. However, laser vision correction provides a permanent solution that eliminates the daily upkeep of contacts, avoiding potential risks and discomfort while greatly improving vision and satisfaction for patients.
Toric intraocular lenses are used mainly in cataract surgery to fix astigmatism. They work well for patients getting lens replacements but are usually only for those with cataracts. In contrast, laser refractive surgery can be done on its own and is a good option for young adults or anyone wanting to correct astigmatism without surgery to replace their lens.
Yes, LASIK can effectively correct astigmatism. It's important to know the eligibility requirements and compare LASIK with other options before deciding. Talking to an experienced ophthalmologist can help you see if LASIK fits your vision needs and goals. With the right approach, LASIK eye surgery can improve your vision and quality of life, especially if you have astigmatism. S
