People living with Astigmatism should be cautious while deciding whether or not to undergo LASIK. A side effect of LASIK and comparative treatments may exacerbate already existing Astigmatism, and this is because the operation involves manipulating and reshaping the cornea.

As a result of developments in ophthalmic technology, most drawbacks may be eliminated. Your eye doctor can help you decide whether LASIK is right for you. 


What is the Root Cause of Astigmatism?

When the front of the eye has two distinct curvatures, it results in Astigmatism (the cornea). Like a soccer ball, the typical eye is spherical. When light enters the eye, it may be focused on the light-sensitive tissue (the retina) at the back, resulting in a clear picture. Astigmatism causes a person’s eye to resemble a rugby ball. Because light enters the eye from two directions, it does not concentrate on a single spot on the retina when emitted by this form. In the end, you’ll have hazy or distorted eyesight.

Some degree of Astigmatism is present in a large percentage of the population. Mild Astigmatism does not significantly affect most people’s vision and does not need to be corrected. Correction is required if Astigmatism results in blurry or distorted vision. Myopia and long-sightedness (hyperopia) are significant causes of Astigmatism (hyperopia).


What are the Signs of Astigmatism?

Visual distortion at all distances is the most common sign of Astigmatism. In addition to headaches and squinting, you may also feel weariness, eyestrain, and headaches when reading. Astigmatism may be diagnosed during a standard eye exam by an optometrist.


What Are Some Ways to Fix Astigmatism?

Astigmatism may be treated in three ways: using glasses, contacts, or LASIK surgery. Astigmatism may be treated with spectacles or contact lenses on a prescription basis (along with long-sightedness or short-sightedness, if necessary). If you have Astigmatism, LASIK eye surgery may fix it and improve your vision. If you’re nearsighted or farsighted, your vision may be improved at the same time as your refractive surgery.


What Kinds of Astigmatism Can’t Be Fixed with LASIK?

Laser eye surgery for Astigmatism can be performed on most patients who meet the criteria for LASIK eligibility. However, some forms of Astigmatism cannot be corrected with LASIK surgery, and LASIK may not fix irregular Astigmatism.


Is LASIK Effective in Treating Astigmatism?

Yes, that’s the quick answer! It is widely accepted that LASIK surgery is one of the most effective and long-lasting treatments for Astigmatism. When the cornea (the front surface of the eye) becomes more asymmetrical than usual, it results in Astigmatism. 

When expert surgeon does LASIK, they use a specific laser designed to reshape the cornea and correct how light bends and focuses on the retina, resulting in clearer vision. By eliminating Astigmatism’s adverse effects, LASIK surgery also removes the need for glasses or contacts altogether.


What Does Will happen in the Case of High Astigmatism?

Astigmatism occurs when the cornea or lens of the eye is unevenly shaped, resulting in fuzzy vision. Reading difficulties, headaches, and other symptoms are common in those with high Astigmatism.

LASIK surgery, contact lenses, or spectacles may all treat severe Astigmatism. As the degree of astigmatism increases, the options for contact lenses narrow. According to the experts, some individuals don’t enjoy using contact lenses or don’t see a significant improvement in their vision with toric lenses for Astigmatism. Others may not undergo surgery or use contacts because their eyes are too tiny.

It’s up to each individual to choose which approach works best for them. To identify the best treatment for high Astigmatism, most patients first attempt various choices. People with high Astigmatism eventually become bored of wearing glasses or contact lenses and opt for LASIK instead.

LASIK may be an excellent choice for those with severe Astigmatism who cannot benefit from any other procedure. To permanently address cornea defects, LASIK surgery has been used. 

Astigmatism-prone individuals’ vision may improve, but they may still need corrective lenses such as contact lenses or spectacles to get the desired outcomes. LASIK may cause some people to have issues seeing at night or being sensitive to light, although most patients have no problems.


What Are The Drawbacks of LASIK Surgery?

LASIK surgery is an outpatient treatment that requires no anaesthesia. LASIK may have the following drawbacks:


  • One of the most prevalent post-procedure side effects is dry eyes. It may continue to bother you for up to six months following your operation.


  • Thin corneas are more likely to suffer from this condition. During the treatment, a portion of the thinned cornea may pop out. The eye may get infected if this thinned-out section ruptures.


  • Seeing rainbow-like rings (halos) around light sources and excessive watering of the eyes are common symptoms of glaucoma, a condition that affects the optic nerve.


  • Removing fewer flaps than necessary may not be sufficient to eliminate myopia. Lenses with lower power may still be required for the individual.


  • Nearsighted people may become farsighted because of corneal reshaping that is excessive. If a corneal flap is infected or torn, it might cause irreversible vision loss.


How Long Will It Take Me to Heal From LASIK for Astigmatism?

Patients with Astigmatism who have LASIK surgery report immediate improvement, but complete recovery and healing typically take three to six months. Follow your surgeon’s post-LASIK recommendations as closely as possible to ensure a speedy and full recovery and avoid any unexpected problems.
