Understanding Astigmatism: Causes and Symptoms
Astigmatism is a vision problem caused by the cornea or lens’s irregular shape, leading to distorted and blurred sight. Fortunately, laser eye surgery can solve this refractive error with effective vision correction results. It’s worth learning about its different types and symptoms in order to get an accurate diagnosis when necessary.
Eye surgery using lasers has become increasingly popular for rectifying astigmatism. It helps those with impaired visual acuity due to their distorted corneas/lenses regain clear visuals at all distances without complications or delay.
The procedure works swiftly but should be carried out under professional supervision only so that your eyes receive ample protection against any potential risks posed during the treatment and following it afterwards – something you wouldn’t want to overlook!
Causes of Astigmatism
Vision correction for astigmatism can be achieved when the irregularly shaped cornea or lens is corrected. Usually, a normal eye has an even and rounded curvature on its cornea, allowing light rays to focus accurately onto one point at the retina. In cases of astigmatic eyesight, this curve becomes distorted, causing illumination rays to land unevenly at multiple points instead, leading to blurred sight lines.
Professionals use various glass lenses, contact solutions, and laser vision procedures such as LASIK, PRK, and SMILE to provide effective remedies for any distortion caused by astigmatism.
Types of Astigmatism
Astigmatism is a visual defect that can be divided into three types: regular, irregular, and mixed. This condition might be due to an abnormal shape of the cornea or lens, misaligned eyes, or certain eye diseases that need medical attention.
People who have this vision issue experience blurred sight at all distances along with other related discomforts such as headaches, eyestrain, and even having trouble seeing things properly under low illumination conditions.
Luckily, one can address astigmatism in several ways, including corrective lenses like glasses/contact lenses and laser surgery interventions. It is able to provide a definitive solution since these types of operations enable fixing ocular irregularities quickly – thus allowing clearer visions once again for those affected by this problem.
Common Symptoms
Astigmatism can cause a variety of vision-related symptoms, including blurred or distorted vision, difficulty with nighttime sight, and squinting. It may even result in eyestrain when focusing for too long, as well as headaches.
Farsighted individuals could also experience similar effects to astigmatism, so it is crucial to have an eye care specialist accurately diagnose any issue related to your eyesight. Make sure you ask about the different options available should treatment be necessary, such as alleviating the strain on one’s peepers due to this condition.
Laser Eye Surgery Options for Astigmatism
If you have astigmatism and are considering laser vision correction, several treatments can be used to reshape your cornea. These include SMILE, LASIK, and LASEK/PRK procedures, which will help bring light rays into proper focus on the retina for improved vision.
This article outlines each of these different types of laser eye surgeries in order to assist with correcting astigmatism, providing an overview of how lasers work on the eyes along with details about why they may be preferable over other options available.
SMILE
Laser eye surgery, or Small Incision Lenticule Extraction (SMILE), is a method of vision correction specifically designed to treat myopic astigmatism, which usually coexists with short-sightedness up to -3 dioptres.
Its minimally invasive and flapless approach makes this laser vision correction procedure particularly attractive compared to other alternatives in the field.
Using femtosecond lasers, surgeons are able to generate a small lenticule within the cornea, which can then be extracted through a microscopic incision as part of reshaping it for accurate optical focusing capability when dealing with issues such as astigmatism combined with nearsightedness.
LASIK
LASIK, or Laser-Assisted In Situ Keratomileusis, is an eye surgery that uses a laser to reshape the corneal tissue and treat refractive errors such as astigmatism, nearsightedness, and farsightedness.
The procedure involves making a tiny flap in the cornea with a laser so that another can be used for vision correction underneath it. Many specialised clinics offer this advanced form of laser eye surgery to their patients, which allows light rays to focus onto one’s retina without needing contact lenses or glasses anymore.
LASEK/PRK
Laser eye surgery involves reshaping the cornea using an excimer laser, such as Laser-Assisted Sub-Epithelial Keratomileusis (LASEK) and Photorefractive Keratectomy (PRK). These laser vision correction procedures are a good choice for certain people with astigmatism due to their lower risk of thinning the patient’s cornea compared to LASIK.
They have some drawbacks – longer healing periods and less comfortability than other types of eye surgeries might be experienced by patients afterwards. Vision can still improve markedly after these operations in terms of clarity.
Assessing Suitability for Laser Eye Surgery
Before having laser eye surgery, it is important to assess whether or not you are an appropriate candidate for the operation. Factors like changes in prescriptions over time, age and overall eye health must be taken into consideration.
In this passage, we will explain how these different aspects can influence your eligibility for a laser procedure.
Prescription Stability
When considering laser eye surgery, ensuring prescription stability is a major factor in achieving successful results. This requires no notable changes to your eyeglass or contact lens prescription for an extended period of time (typically one year).
Age, habits, and health can all influence the steadiness of your vision, hence why keeping it consistent is so important when undergoing this type of eye procedure. Having stable eyesight will help ensure clear vision after finishing the laser process.
Age Requirements
The use of laser eye surgery is subject to age-related criteria. 18 is the minimum, and 65 is the maximum. There may be certain circumstances in which clinics will consider patients who are either younger than eighteen or older than sixty-five, depending on how they meet specific requirements.
It is paramount that a person’s circumstances should be discussed with their appointed ophthalmologist before any procedure commences. Laser technology must not only remain within these parameters but also needs to benefit both parties involved for successful results.
Overall Eye Health
For someone to be a viable candidate for laser eye surgery, their prescription strength and age are taken into account, and overall ocular health as well. Some of the conditions that could have an effect on this decision include glaucoma, cataracts, macular degeneration or astigmatism. To maintain healthy eyes, it is essential to keep up with visits to your optometrist so that any necessary treatments can be administered promptly.
It’s important when considering laser eye procedures such as Lasik vision correction surgeries and other operations related to optical issues like refractive error treatment using lasers that optimal wellness of one’s eyes must always come first in order for them to gain approval from surgeons performing these delicate activities.
Risks and Safety of Laser Eye Surgery for Astigmatism
When considering laser eye surgery for astigmatism, it is crucial to be aware of the potential hazards and consequences associated with this type of procedure. This part will include safety protocols in place as well as any risks or side effects that may occur due to the operation.
From a medical point of view, laser eye treatment for astigmatism has been deemed safe. Doctors take precautionary steps to reduce any complications from taking place. Prospective patients should take into account all possible outcomes when deciding on opting.
Potential Risks
Laser eye surgery has several potential risks, such as discomfort or pain, dry eyes, glare, and halos. It can result in under-correction of vision issues or over-correction, double vision, corneal haze, and scarring. The laser treatment’s compression results in blurred night vision problems and decreased sharpness of sight.
Any person considering this type of eye surgery must have an extensive conversation with their ophthalmologist about these dangers beforehand to make an informed decision about the operation.
Side Effects
Eye surgery for astigmatism with laser beams has potential side effects such as dry eyes, heightened light sensitivity, glare, and halos around lights. There can also be issues of double vision or too little/too much correction in the process.
Regular check-ups are necessary to help mitigate these occurrences while following your surgeon’s instructions is an important step in achieving a successful outcome. Using lasers when it comes to eye operations involving correcting astigmatic sight could have advantages, but knowing what possible outcomes there may be beforehand will prove beneficial overall.
Safety Measures
Adopting the essential safety protocols of pre-operative testing, employing state-of-the-art technology, and post-operative care is imperative to guarantee a safe laser eye surgery experience for people living with astigmatism. By following these guidelines and working closely with your ophthalmologist, you can reap all this procedure’s benefits without compromising your vision health.

Frequently Asked Questions
Is laser eye surgery suitable for astigmatism?
Laser eye surgery can be used to effectively treat astigmatism as the laser is able to reshape the cornea of the eye, thus eliminating any vision difficulties related to this condition. If, in some cases, one’s astigmatism is too irregular, they may not qualify for this type of surgical procedure.
Laser-assisted technologies and techniques are specifically designed to provide improved eyesight by correcting issues caused by problems like astigmatism or other forms of impaired vision.
Can your astigmatism be too bad for LASIK?
The American Refractive Surgery Council outlines that individuals with astigmatism can have a LASIK procedure up to +6.00 diopters for hyperopia (long-sightedness), six diopters for astigmatism, and -12.00 in terms of myopia (short-sightedness). Beyond this limit, it may be too extreme for the surgery.
What are the main types of astigmatism?
Astigmatism manifests in two primary forms:
Corneal Astigmatism: Occurs when the cornea, the front surface of the eye, isn’t perfectly curved.
Lenticular Astigmatism: This arises from an irregularly shaped lens inside the eye. In both cases, this irregularity results in blurred vision
Will I still need glasses or contact lenses after laser eye surgery for astigmatism?
Many individuals who opt for laser eye surgery to correct astigmatism find a remarkable improvement in their vision. Often, the dependency on glasses or contact lenses is significantly reduced. However, depending on individual needs and the nature of tasks – like reading or nighttime driving – some may still prefer the clarity provided by corrective lenses.
Is the laser eye surgery procedure painful?
The very thought of a laser being used on one’s eyes can be unsettling for some. However, be assured that the eye is numbed using anaesthetic drops prior to surgery. While the sensation of pressure might be felt. Any discomfort or mild ache post-surgery is typically transient, easing in a matter of days.
What is the success rate of laser eye surgery for astigmatism?
Laser eye surgery boasts a commendable success rate for astigmatism correction. Most patients post-surgery have a visual acuity of 20/40 or even better. This level of vision is, in most jurisdictions, sufficient to drive without the aid of corrective lenses. It’s essential to note that individual results can vary based on the severity of astigmatism and other personal factors.
How long do the results of laser eye surgery last?
The results of laser eye surgery are typically long-lasting. Once the cornea has been reshaped, the results are usually permanent. However, some patients may experience changes in their vision over time due to normal ageing processes or other eye conditions.
