Yes, you absolutely can get LASIK if you have astigmatism. In fact, LASIK is a very effective treatment option for many people with astigmatism. Many LASIK surgeons routinely correct astigmatism during the procedure. It's a common condition, and the technology used in modern LASIK procedures is designed to address it.
What is Astigmatism?
Before we delve into how LASIK treats astigmatism, let's briefly understand what it is. Astigmatism is a refractive error where the cornea (the clear front part of your eye) is irregularly shaped. Instead of being perfectly round like a basketball, it's more oval-shaped like a football. This irregular shape causes light to focus unevenly on the retina, resulting in blurred vision at all distances. Symptoms can include blurry vision, eye strain, headaches, and difficulty seeing at night.
How LASIK Corrects Astigmatism
LASIK surgery uses a laser to reshape the cornea, correcting the refractive error. When it comes to astigmatism, the laser precisely reshapes the cornea to create a more regular, spherical shape. This allows light to focus properly on the retina, improving visual acuity and eliminating blurry vision.
The LASIK procedure itself is essentially the same whether or not astigmatism is present. The key difference lies in the way the laser is programmed. The surgeon uses advanced technology, such as wavefront-guided LASIK, to create a highly customized treatment plan that addresses the specific irregularities of your cornea, including the astigmatism.
What are the Risks and Side Effects?
While LASIK is generally safe and effective, it’s important to be aware of potential risks and side effects. These can include dry eyes, halos or glare around lights (especially at night), and under- or over-correction. However, these side effects are usually temporary, and advancements in LASIK technology have minimized their occurrence. Your ophthalmologist will discuss these risks in detail during your consultation.
Will LASIK Completely Cure My Astigmatism?
LASIK aims to significantly improve your vision, often to the point where you no longer need glasses or contacts. However, it's not a guarantee of perfect 20/20 vision for everyone. The level of improvement depends on several factors, including the severity of your astigmatism and your overall eye health.
Can I Get LASIK If I Have High Astigmatism?
While LASIK can be performed on individuals with high astigmatism, the suitability will be determined during a comprehensive eye examination. High astigmatism may require a more complex procedure or alternative refractive surgery. The ophthalmologist will assess your unique situation and recommend the best approach.
How Do I Know if I'm a Good Candidate for LASIK?
Determining candidacy for LASIK requires a thorough eye exam. This will include assessing your corneal thickness, overall eye health, and the degree of your astigmatism. Your age, general health, and lifestyle will also be considered. Only after a comprehensive evaluation can an ophthalmologist determine if LASIK is the right option for you.
What Happens During a LASIK Consultation?
During a consultation, the ophthalmologist will perform a comprehensive eye exam, discussing your medical history, visual needs, and expectations. They'll explain the LASIK procedure in detail, answer all your questions, and determine if you're a suitable candidate. This consultation is crucial for making an informed decision.
