Astigmatism can sometimes recur after a LASIK procedure, which can be caused by a number of different reasons. First, there is the possibility that the correction obtained from the procedure was not perfect, and the residual astigmatism is what has been detected.
This is more common in higher levels of pre-operative astigmatism, as it can be more difficult to precisely measure and correct for.
Another possible cause of recurrence is that, even in the very best cases, the tissue surrounding the cornea can still continue reshaping itself slightly over time. This process may cause the original correction to shift and for the astigmatism to reappear, although it usually does so slowly.
Lastly, it is also possible that other conditions, such as keratoconus, may develop after the procedure. This is more common if an individual had a condition called forme fruste keratoconus prior to their LASIK surgery, and this can cause the astigmatism to reappear afterwards.
All of these factors can cause astigmatism to recur after LASIK, and if this occurs then it is strongly advisable to have the situation assessed by a trained optometrist or ophthalmologist in order to determine the exact cause and any necessary corrective treatment.

How long does LASIK last for astigmatism?
The longevity of LASIK for astigmatism depends on many factors, including the individual’s age, lifestyle, and overall health. Generally speaking, LASIK patients with astigmatism can expect results to last for at least several years.
Studies show that LASIK for astigmatism can last for up to 12 years or more. People who have LASIK for astigmatism can sometimes need a touch-up procedure due to changes in the shape of the cornea which can occur over time.
Age and genetics may contribute to these changes.
It’s important for LASIK patients to remember that LASIK does not stop the natural aging process of the eyes. Even after having LASIK, patients may still need to wear eyeglasses or contact lenses depending on the severity of astigmatism or as one ages.
LASIK is not a one-time fix but rather a long-term solution that requires follow-up care and a commitment to proper eye care. By following best practices and making regular, scheduled visits to your eye doctor, you can ensure that your LASIK lasts as long as possible.
Does LASIK permanently fix astigmatism?
Yes, LASIK can be used to permanently treat astigmatism. However, it is important to note that not all individuals are good candidates for LASIK, and some may not be able to benefit from it. During the LASIK procedure, a laser is used to carefully reshape the cornea to correct the refractive error of astigmatism.
This can help to focus light entering the eye more accurately onto the retina and provide clear, sharp vision. While the effect of LASIK is usually permanent, individuals may still experience a gradual, age-related change in their refractive status over time.
Therefore, some people may need an additional treatment or ongoing vision correction, such as glasses or contact lenses, to maintain their vision. In rare cases, LASIK may have the opposite effect and worsen the astigmatism, so it is important to consult a qualified eye care professional to determine if you are a good candidate for the procedure.
Why do I have blurry vision 2 years after LASIK?
It is possible to have blurry vision up to two years after LASIK surgery, even though most people experience improved vision quickly after the procedure. This is due to a variety of factors, including age, the original condition of the eye prior to the procedure, and the individual healing process.
Most likely, your blurred vision is not due to something going wrong during the procedure but instead caused by an inadequate or uneven healing process.
Age can be a factor since our vision can decline as we age. After LASIK, any natural decline in vision that had already been happening may become more noticeable. Additionally, if the eye had already begun to develop cataracts prior to the procedure, this may influence the blurry vision.
The individual healing process also plays a role in the recovery after LASIK. Ultimately, the LASIK procedure does not make the eye perfect, but rather just helps it return to the normal vision for your age.
Therefore, everyone will have their own unique recovery rate and if their vision is not perfect it does not necessarily mean that something has gone wrong. In some cases, it can take as long as two years to recapture the full vision used prior to LASIK.
It is also important to ensure that you are taking the right steps to protect your eyes after the procedure and give your eyes the best opportunity to heal. You want to use protective eyewear when outdoors, keep your eyes clean and moisturized, and practice proper hygiene.
Additionally, it is recommended that you visit your ophthalmologist periodically to monitor your vision after your procedure.
If you have blurry vision two years after LASIK, it is a good idea to reach out to your ophthalmologist to discuss your options. They may be able to perform a specialized procedure to help improve your vision if other methods have not been successful.
Is laser eye surgery worth it if you have astigmatism?
Yes, laser eye surgery can be worth it for people who have astigmatism. Laser eye surgery, also known as LASIK, is a procedure that uses a laser to reshape the cornea of the eye to help correct vision problems.
It can be used to treat a variety of vision issues, including astigmatism. During the procedure, a flap is created in the cornea, and the laser treatment is then used to reshape it in a way that helps to reduce any blurring of vision, which can be caused by astigmatism.
In most cases, the results of laser eye surgery for astigmatism are often much better than what would be achieved with glasses or contact lenses alone. The benefits of laser eye surgery for astigmatism are that it can often result in better than 20/20 vision, and it can improve vision without the need for glasses or contact lenses.
As with any medical treatment, it is important to thoroughly research and discuss the risks and benefits of laser eye surgery for astigmatism with a qualified eye doctor before making a decision.
Do eyes ever fully heal after LASIK?
Yes, eyes do fully heal after LASIK. The recovery time is usually only a few days, and there is often minimal discomfort during the healing process.
Most people achieve 20/20 vision or better after LASIK surgery and results usually last for a long time. The effects of the procedure are maintained for a number of years and vision rarely progresses to worse than pre-surgery levels.
However, it is important to note that vision may still change over time due to normal aging factors, such as presbyopia. This can be mitigated by performing a follow-up laser vision correction surgery, if necessary.
People who have LASIK should monitor their vision regularly to ensure that any vision changes do not adversely affect their vision.
Overall, LASIK is a relatively safe and effective procedure that can improve the vision of those suffering from refraction errors. With a proper recovery period, eyes should fully heal after LASIK and provide improved vision.
What astigmatism is too high for LASIK?
Astigmatism is a condition that is caused by an uneven curvature of the eye, which results in blurred vision. Generally, LASIK can be used to correct astigmatism of up to 6 diopters. However, astigmatism of more than 6 diopters is too high for LASIK, as the potential risks from the surgery often outweigh the potential benefits.
Patients with high astigmatism may be better candidates for other forms of vision correction, such as photorefractive keratectomy (PRK). Additionally, there are specialized laser eye treatments, such as limbal relaxing incisions and corneal relaxing incisions, that are designed for high astigmatism.
Ultimately, it’s important to speak to an eye doctor to discuss the best treatment options for you.
Can astigmatism go away?
Yes, it is possible for astigmatism to sometimes go away. Depending on the cause and severity of the astigmatism, it may be possible for the problem to be corrected without the need for surgery or other medical treatment.
In some cases, people with mild astigmatism may even notice their astigmatism improving over time. This is because the eye is able to remodel itself in response to environmental and visual demands. Over time, the shape of the cornea in the eye may return to a normal, non-astigmatic shape.
If the astigmatism is caused by pathology it is less likely to improve over time, however, laser corrective surgery or Orthokeratology may help modify the shape of the cornea and lead to improved vision.
What is the limit for LASIK for astigmatism?
The limit for astigmatism during a LASIK procedure depends on several factors, including the laser used, the skill of the surgeon, and the patient’s anatomy. Generally speaking, the maximum ideal correction for astigmatism with LASIK is approximately 4 diopters.
However, it is not uncommon for experienced surgeons using modern laser technology to correct more than 4 diopters of astigmatism in certain cases with favorable patient anatomy. In fact, some surgeons have been able to safely and successfully correct up to 6 diopters of astigmatism with the IntraLase femtosecond laser and the Allegretto Wavelight excimer laser.
Can you have a second eye laser surgery twice?
Yes, it is possible to have laser eye surgery more than once. Depending on the type of laser surgery, your reasons for needing additional surgery and the condition of your eye, a second laser eye surgery may be an option.
When considering a second laser eye surgery, it is important to have a thorough eye examination beforehand to make sure that you are a good candidate for the procedure. It is possible that a different type of procedure might be a better option for achieving the desired results.
In some cases, people may need a second eye laser surgery because the original procedure was not successful in fully correcting their vision. It is also possible that a person’s vision may change over time, and additional laser surgery is needed to bring it back into line.
The technology that is used for laser eye surgery has improved over the years, so repeat procedures may have even better results than the initial surgery. It is essential to consult with a highly qualified and experienced eye doctor to get an evaluation of whether a second laser surgery is a good option for you.
Which eye surgery is for astigmatism?
Astigmatism can be corrected through a laser eye surgery known as Orthokeratology. Orthokeratology (also known as Ortho-K or corneal refractive therapy) is a non-surgical, reversible procedure that reshapes the cornea to correct astigmatism.
It involves wearing fitted contact lenses at night that temporarily reshape the cornea and correct the astigmatism. In the morning, the lenses are removed and the patient can see clearly without the need for glasses or contact lenses.
Orthokeratology is a safe and non-invasive process and over time its effects will remain even without treatment. Additionally, Orthokeratology is especially beneficial for those individuals who do not want to wear glasses or contact lenses.
In most cases, full functional vision can be restored in one to two weeks with the use of Orthokeratology.
What happens if vision is not corrected after LASIK?
If vision is not corrected after LASIK, it is possible to experience blurred vision and decreased vision quality. This can happen if the cornea retains irregularities after the procedure, causing the eyesight quality to remain below the desired level.
Over- or under-corrections of the refractive errors can also lead to blurred, decreased vision. If the refractive error was not corrected during the first procedure, a second surgery may be required to produce optimal results.
Regardless of whether a subsequent surgery is needed, it is important to follow up with your LASIK surgeon to monitor your vision and address any issues that may arise.
How many times can you get LASIK?
LASIK is a very safe and effective procedure, and it typically needs to be repeated only once over a patient’s lifetime. However, every patient’s eyes are unique and some people may wish to have a touch-up or enhancement procedure at a later stage.
It is possible to have LASIK surgery more than once, but it is generally not recommended unless it is really necessary. The Mayo Clinic states that the safety, success, and long-term effects of LASIK are not known when the procedure is repeated.
It is possible to have the same procedure done twice, but this should only be done after a thorough evaluation of the results of the first one. Your ophthalmologist or optometrist can help you to determine whether having LASIK multiple times is right for you.
Are eyes weaker after LASIK?
Generally speaking, no, eyes are not weaker after LASIK. This is because LASIK techniquest used today are much more precise than older methods. So in most cases, the refractive error can be addressed without affecting the strength of the eye.
In fact, many people actually experience improved vision following LASIK, as the cornea can now focus more accurately.
Having said that, there are some rare cases when LASIK can result in a slight drop in vision acuity. This can happen if the cornea is weakened or the eye is affected by a condition such as dry eyes or astigmatism.
In these cases, a patient’s eyesight may not be as sharp after the surgery as it was before.
It’s important to note that LASIK is only one method of vision correction, and that there may be other solutions that can provide improved vision without any potential side effects. To ensure the best outcome, be sure to discuss your options with a qualified eye specialist.
Is it common to need LASIK twice?
The need for LASIK surgery can vary from person to person, and some may require multiple surgeries. In general, the need for a second LASIK procedure is uncommon. Most people will only need one LASIK procedure to achieve their desired results, and this is typically enough to provide them with stable, long-term vision correction.
However, there are some cases where a person may need a second LASIK procedure. This is usually due to the fact that the eye may not have healed properly after the first surgical procedure, leading to a gradual loss of vision over time, or the patient may not have obtained their desired results and would like to improve their vision further.
Additionally, if the patient’s vision changes or progresses due to age, lifestyle, or an eye condition, they may need a second LASIK procedure to correct their vision. In some cases, a patient may need multiple consecutive LASIK procedures due to the development of a chronic or recurrent eye condition or disease.
For all of these reasons, it is important for patients to understand that a second LASIK procedure may be needed, but it is not common.
