The meaning of “Astigmatism..”
One of the common symptoms of this eye condition is blurred or distorted vision. We don’t know what causes Astigmatism, but it’s thought to have something to do with a lens that’s not perfectly round. Regular Astigmatism describes the vast majority of myopic conditions. It means that the incoming light is not focused precisely on the retina’s back (the light-sensitive layer at the back of your eye). As a result, images may appear hazy or fuzzy.
Another form of Astigmatism, myopia, is brought on by a lens that is too curved. An abnormal concentration of incoming light on the retina causes blurred vision.
Laser Eye Surgery (LASIK) Variations
Laser in situ keratomileuses (LASIK) and refractive surgery using a wavefront-guided device (RKD) are the two most common forms of LASIK surgery. The most prevalent kind of LASIK procedure is called laser in situ keratomileuses. The procedure includes reshaping the cornea. It helps with both short- and long-sightedness as well as Astigmatism. Patients with severe Astigmatism may consider refractive surgery using a wavefront-guided device. The cornea is realigned with the aid of a particular machine in this type of surgery, allowing for sharper vision.
How exactly does LASIK surgery work to correct the condition for those with Astigmatism?
We can cure Astigmatism with LASIK surgery. The cornea is reshaped with a laser, which can help vision by flattening the usually curved front surface of the eye. With few exceptions, LASIK is a risk-free and highly effective procedure. Most patients report better eyesight just days after surgery.
Those who meet the criteria for LASIK surgery based on their eyesight tests can be identified by the rules of thumb. If you have Astigmatism of a regular shape, your diopter count is six or less, and your cornea is healthy, you may be a candidate for LASIK. Your nearsightedness or farsightedness may affect whether or not LASIK is a good option for you. Your myopia must be less than -12D or more than +6D, respectively, to get qualified for this procedure. Whether or not you can go for LASIK surgery depends more than how well you see in the distance. Then there are also:
What you hope to achieve with glasses or contacts
your age, your age-related changes in eyesight, and other factors related to your eyes’ overall health, such as corneal thickness and tear production (you must be 18 or older)
The condition of your health (those with conditions like autoimmune diseases or diabetes may not be eligible.
Risks Associated with LASIK Eye Surgery
Patients, however, need to know that LASIK is not without its risks. Dry eyes, headaches, and other visual disturbances are all potential LASIK side effects. Patients also need to know that impaired vision is a possible side effect of the procedure. And in some cases, LASIK may not be able to correct Astigmatism at all.
How Common Is Lasik Procedure?
While LASIK surgery has dramatically increased the success rate of correcting Astigmatism, it is not a foolproof method. The success rate of LASIK is approximately 85% to 90%, as reported by the American Academy of Ophthalmology. Around 15%-25% of those who undergo LASIK are dissatisfied with the outcome. Their Astigmatism may be too severe, or their eyes may not be healthy enough to undergo surgery.
What to Anticipate?
Once your doctor gives you the OK, you can head home after completing your LASIK surgery. You will not be allowed to leave the hospital in your vehicle. After LASIK surgery, resting and sleeping will help your body recover. Your comfort may not fully return for a while after the procedure. Any antibiotic or lubricating eye drops prescribed by your doctor will be provided. In addition, you might need to protect your eyes with goggles for a while. Stop exercising and swimming until your doctor says it’s OK.
After the operation, you will need to see your doctor multiple times. One could be the day after surgery, while the others could be set for weeks later. After the procedure, you may need three to six months for your eyesight to stabilize. Some glare or blurriness may be present at that time. Patients who undergo LASIK are generally pleased with the results. More than 95% of LASIK patients in one old study from 2009 reported being happy with the results. The research summarised for 2020 finds that LASIK is “effective and predictable” in treating mild to moderate degrees of Astigmatism.
When to Consult a Physician?
No matter what process you choose to treat a refractive eye condition like Astigmatism, it would help if you kept in touch with your doctor. LASIK could be a good option if you don’t want to bother with glasses or contacts. Schedule a separate appointment, or bring it up during your next routine checkup if you have any concerns about your vision. Maintain consistent communication with your doctor after your LASIK surgery. Seek medical attention immediately if you experience severe or unusual symptoms, significantly if they affect your vision. If you’re experiencing any other symptoms, you must let your doctor know so they can give you an idea of your recovery timeline.
Last but not least, It’s a refractive error caused by the abnormally curved cornea. The corneal shape can be altered through LASIK surgery, reducing the effects of Astigmatism. Discuss your interest in this procedure with your doctor to determine if you qualify. Sometimes, LASIK can be used to correct vision instead of conventional methods like glasses or contacts.
Cost for LASIK
The most common type of eye surgery, laser-assisted in situ keratomileuses (LASIK), is also an excellent method for treating Astigmatism, with very few risks. LASIK surgery costs can range from INR 40,000 to 1,40,000, depending on the surgeon and the precision of the LASIK laser being used.
Commitment Time for LASIK
Knowing how long LASIK surgery will take is crucial if you’re thinking about doing it. It usually takes around two hours to perform the entire operation. Some patients, however, might benefit from extra time to get ready for surgery. Additionally, post-operative care may necessitate several follow-up visits. As a result, LASIK can require anywhere from a few hours to several days or weeks of your time.
The effectiveness of LASIK surgery for correcting Astigmatism is still heavily debated. Nonetheless, many people decide to undergo the operation to enhance their quality of life. LASIK surgery has some adverse side effects, such as pain and blurred vision, but many patients report positive outcomes that improve their daily lives. Talk to your doctor about your LASIK options if you have Astigmatism and are considering corrective eye surgery.
