Astigmatism is a common refractive error of the eye and can be lenticular, corneal, or retinal. If left untreated, it can lead to vision loss. If you have astigmatism, you are still eligible to receive LASIK eye surgery. In fact, LASIK treatment works best in those with refractive errors such as farsightedness, nearsightedness, and astigmatism.
People with astigmatism can receive LASIK vision correction. LASIK can fix a number of problems associated with the eyes. Since astigmatism is a refractive error, LASIK is an ideal procedure to correct it.
How LASIK Works
LASIK uses a laser to change the shape of the cornea and improve vision. This strong beam of light can also be used to place implants and make other changes. LASIK works correctly if the individual’s vision is stable.
LASIK is a specific procedure and isn’t right for everyone. Certain eye conditions, such as infections, large pupils, glaucoma, dry eye, or cataracts, increase the risk of LASIK complications. Side effects include double vision, light sensitivity, glare or halos around bright lights, dry eye, or blurry vision.
Signs and Symptoms of Astigmatism
According to the National Library of Medicine, there are common symptoms associated with astigmatism. Some of the symptoms consist of the following:
- Blurred vision
- Discomfort
- Eye strain
Those with astigmatism may exhibit numerous signs associated with the condition. For instance, those with astigmatism may experience:
- Partial eyelid closure or frequent squinting
- Tilted optic discs, such as deficient color vision, retinal abnormalities, myopia, or visual field loss
- Abnormal head tilt
- Different power in different meridians, known as horizontal or vertical imaginary lines across the eye
Thankfully, astigmatism can be managed with surgical correction, contact lenses, or glasses.
Types of Astigmatism
There are numerous types of astigmatism that patients may suffer from. Types of astigmatism include the following:
- Corneal astigmatism – With this common astigmatism, the cornea has an uneven shape instead of a round one.
- Lenticular astigmatism – An irregular lens shape defines this type. This distortion of the lens results from astigmatism.
- Retinal astigmatism – With retinal astigmatism, the curve of the cornea prevents light from focusing evenly on the retina, creating blurry vision.
Simple astigmatism – This occurs when light creates two focal points. The focal points are located in front of the retina and one directly on the retina. - Mixed astigmatism – Those with mixed astigmatism struggle with both nearsightedness and farsightedness in one eye.
Compound astigmatism – When two focal points are in front of the retina, but in separate locations, this is known as compound astigmatism. - Oblique astigmatism – This astigmatism is an irregular curve in the eye in which the focus is tilted diagonally instead of vertically or horizontally.
- Bioblique astigmatism – Although this condition is rare, it causes the main lines of sight to change. With this astigmatism, the main lines of sight are not right angles to each other.
If you have noticed a change in your eyesight or have developed any itchy or painful sensation, consider having your eyes checked for astigmatism. LASIK treatment may be beneficial for those suffering from specific types of astigmatism.
