Can you get LASIK twice?

If you’ve had LASIK surgery before and your vision has changed over time, you might be wondering whether you can have the procedure again. It’s a common question, especially for those who had the procedure 10 or 20 years ago and are now noticing their eyesight isn’t as sharp as it used to be.

While LASIK is designed to provide long-term vision correction, it doesn’t prevent natural changes in the eyes. Age-related factors like presbyopia or slight shifts in prescription can lead some people to consider a second LASIK procedure, also known as an enhancement or retreatment. But is having LASIK twice safe? How many times can you undergo laser eye surgery? And are there any risks to be aware of?

A second procedure is possible for some people, but it depends on several factors, including the health of your eyes, the thickness of your cornea, and the reason your vision has changed. In this article, we’ll explore when a repeat procedure might be an option, when it may not be suitable, and what risks are involved.

Those looking for LASIK in Adelaide, may wish to consult with a registered eye specialist to explore whether retreatment is appropriate for their individual needs.

Is it possible to have LASIK more than once?

Yes, it is possible to undergo LASIK surgery more than once, but it depends on several factors, which we’ll explore here. While LASIK is designed to offer long-term vision correction, it does not prevent natural age-related vision changes such as presbyopia or cataract development.

For some people, a second procedure – often called an enhancement or retreatment – may be an option if their vision has changed significantly since their first surgery. However, there are limits to how many times it can be performed safely, which is why a thorough eye examination is essential before considering a second procedure.

It’s essential to consult with a qualified ophthalmologist to determine if a second surgery is appropriate for your individual circumstances.

How many times can you go for LASIK?

The number of times someone can undergo LASIK depends on their corneal thickness. Each procedure removes a small amount of corneal tissue to reshape the eye, so if the cornea becomes too thin, it may no longer be safe to perform additional treatments.

Most patients who need an enhancement will only require one additional procedure in their lifetime. However, in rare cases, some individuals may be able to have LASIK more than twice, provided their cornea remains thick enough and their eye health is stable.

A thorough evaluation with an ophthalmologist will determine if further procedures are a safe option. If additional LASIK is not possible, other vision correction methods such as lens replacement surgery, or implantable contact lenses (ICLs) may be considered.

I had LASIK 20 years ago – Can I have it again?

If you had LASIK 20 years ago, you may still be eligible for a second procedure, depending on your eye health. Over time, some people experience natural vision changes, such as presbyopia (age-related difficulty focusing on near objects) or slight shifts in their prescription.

For individuals who had surgery 20 years ago and are now experiencing changes in their vision, it is possible to consider a second procedure. Advancements in LASIK technology and techniques have made it feasible to perform repeat procedures even decades after the initial surgery.

However, candidacy for a second LASIK surgery depends on factors such as corneal thickness, overall eye health, and the presence of any age-related eye conditions like cataracts or presbyopia¹. A comprehensive eye examination by an experienced ophthalmologist is necessary to assess whether a second LASIK procedure is suitable in such cases.

For those in Adelaide, IVISION LASER can offer an eye assessment to determine whether a second LASIK procedure is the right choice or if another vision correction option would be more suitable.

Why would someone need a second procedure?

While LASIK surgery aims to provide long-term vision correction, various factors can lead individuals to consider a second procedure:

- - Natural aging processes: As we age, our eyes undergo changes. Conditions like presbyopia, which affects near vision, or cataracts, clouding the eye’s natural lens, can develop independently of previous LASIK surgery. These age-related changes can cause vision to become blurry over time².
  - Changes in vision prescription: In some cases, the initial LASIK procedure may not fully correct the refractive error, or vision may change over time, leading to residual refractive errors. This can result in the need for glasses or contact lenses after surgery. A second procedure can address these issues and improve vision³.
  - Post-LASIK ectasia: An extremely rare complication (0.033% of LASIK surgeries) where the cornea becomes unstable and begins to bulge, leading to vision deterioration⁴. This condition may necessitate further surgical intervention.

Why is my vision blurry 10 years after LASIK?

Experiencing blurry vision a decade after LASIK is not uncommon and can be attributed to several factors:

- - Presbyopia: Typically emerging around the age of 40, presbyopia is an age-related condition where the eye’s lens loses flexibility, making it difficult to focus on close objects. This condition affects everyone, regardless of previous surgery⁵.
  - Cataract development: Over time, the eye’s natural lens can become cloudy, leading to cataracts. This results in blurred or hazy vision and is a common age-related change⁶.
  - Regression of vision correction: In some instances, the effects of LASIK can diminish over time, a phenomenon known as regression. This can lead to the return of refractive errors, causing vision to become blurry again⁷.

Repeat LASIK surgery after 10 years – When is it necessary?

Considering a second procedure a decade after the initial surgery depends on several factors:

- - Stability of vision prescription: Before undergoing another LASIK procedure, it’s crucial that your vision prescription has remained stable for at least a year. Fluctuating vision may indicate underlying issues that need to be addressed first.
  - Corneal thickness: Each LASIK surgery removes a small amount of corneal tissue. Sufficient corneal thickness is necessary to safely perform a second procedure. A thorough examination will determine if your cornea meets the required criteria ⁸.
  - Overall eye health: Conditions such as dry eye syndrome, glaucoma, or other ocular diseases may influence the decision to undergo repeat surgery. A comprehensive eye examination is essential to assess suitability.

It’s important to note that while a second procedure can address certain vision issues, it may not be suitable for everyone. Alternative treatments, such as PRK (photorefractive keratectomy) or lens-based surgeries, might be recommended based on individual circumstances. Consulting with an experienced ophthalmologist will provide personalised insights into the best course of action for your vision needs.

Safety and risks of undergoing LASIK again

Undergoing LASIK surgery more than once is possible, but it’s essential to understand the associated safety considerations and potential risks.

Is it safe to have LASIK twice?

LASIK enhancement may be appropriate for some patients, but it is not suitable for everyone. A thorough assessment is required to determine if it’s clinically appropriate. The decision to undergo a repeat procedure depends on several factors:

- Corneal thickness: Each LASIK procedure removes a small amount of corneal tissue. Sufficient remaining corneal thickness is crucial to ensure the structural integrity of the eye for a second surgery⁹.
- Vision stability:A stable vision prescription for at least one year is typically required before considering a second LASIK procedure¹⁰.

Overall eye health: Conditions such as cataracts, glaucoma, or severe dry eye syndrome may influence the suitability of undergoing LASIK again¹¹.

A comprehensive evaluation by an experienced ophthalmologist is necessary to determine if a second LASIK procedure is appropriate for your specific circumstances. It’s important to note that while LASIK is generally safe, repeat procedures may carry a slightly higher risk of complications¹².

Second LASIK surgery risks – What you should know

While many patients achieve satisfactory results with an initial procedure, some may experience vision changes over time due to aging or other factors, prompting consideration of a second surgery. Potential risks specifically associated with undergoing LASIK again include:

Flap complications: Creating a new corneal flap or lifting the existing one can lead to flap stability concerns and increased difficulty in creating new flaps¹³.
Corneal ectasia: A rare but serious complication where the cornea becomes weakened and begins to bulge, leading to distorted vision. This risk increases if there is insufficient corneal tissue remaining after the initial surgery¹⁴.
Increased risk of epithelial ingrowth: Risk of epithelial cell growth beneath the lens increases from 1-12% for first LASIK procedures to 32% for second procedures¹⁵.

It’s really important to weigh these potential risks against the benefits of improved vision. A detailed discussion with your eye surgeon will help determine if a second LASIK procedure is the best course of action based on your individual needs and eye health.

When is a second surgery not an option?

While LASIK surgery has helped many achieve clearer vision, certain factors may make a second procedure inadvisable. Understanding these considerations is crucial for those contemplating another LASIK surgery.

Who is not a suitable candidate for a second procedure?

Several conditions can render an individual unsuitable for a repeat LASIK surgery:

Insufficient corneal thickness: Each LASIK procedure removes a portion of corneal tissue. If the cornea becomes too thin, performing another surgery could compromise its structural integrity¹⁶.
Unstable vision prescription: Candidates should have a stable vision prescription for at least one year. Fluctuating vision may indicate underlying issues that need addressing before considering additional surgery.
Underlying eye conditions: Diseases such as glaucoma, cataracts, or severe dry eye syndrome can affect healing and outcomes, making further LASIK procedures risky¹⁷.
Age-related vision changes: Conditions like presbyopia, which affect near vision as one ages, may not be effectively corrected with LASIK¹⁸.

Can you have LASIK three times?

The possibility of undergoing LASIK surgery three times depends on individual factors:

Corneal health: Adequate corneal thickness is essential for each LASIK procedure. Multiple surgeries may deplete necessary tissue, increasing the risk of complications¹⁹.

In conclusion, while multiple LASIK surgeries are possible for some, they are not suitable for everyone. A comprehensive evaluation by an experienced ophthalmologist is essential to determine the best course of action based on individual eye health and vision needs.

Consultation and next steps

How to find out if you’re eligible for a second LASIK surgery

If you’re considering a second LASIK procedure, the first step is to have a comprehensive eye examination. Your ophthalmologist will assess factors like corneal thickness, overall eye health, and vision stability to determine if LASIK is still an option for you.

During the consultation, you may need tests to measure your cornea and check for any underlying conditions, such as cataracts or dry eye syndrome, that could affect the outcome. If LASIK is not suitable, alternative vision correction options may be discussed.

If you’ve noticed changes in your vision after LASIK, a consultation can help you understand your options and get personalised advice based on your eye health and vision needs.

Conclusion

Having LASIK surgery more than once is possible, but it depends on several factors, including corneal thickness, eye health, and the reason for vision changes. While LASIK provides long-term vision correction, natural aging or slight prescription shifts may lead some people to consider a second procedure.

A second LASIK surgery may be suitable for those with stable vision and enough corneal tissue, but it is not always an option. In some cases, alternative treatments like PRK or lens-based procedures might be recommended instead.

If you’re unsure whether LASIK retreatment is right for you, the best next step is to have an eye assessment. For those in Adelaide, IVISION LASER offers consultations to determine whether a second LASIK procedure or another vision correction option is the best choice for your needs.
