Can I Get LASIK Twice? The Ultimate Guide

LASIK eye surgery has revolutionized vision correction, providing excellent results for millions of people worldwide. With LASIK, most patients achieve 20/20 vision or better and freedom from glasses and contact lenses. However, some people may require an enhancement or second LASIK procedure years later.

In this comprehensive guide, we‘ll answer common questions about getting LASIK again, including:

• Can I get LASIK a second time if my vision changes?
• How long do LASIK results last?
• Is LASIK worth it after 40, 50, or 60?
• What are the risks and limitations of repeat LASIK procedures?
• How do I know if I‘m a candidate for LASIK again?

Let‘s dive in and explore the possibilities of repeat LASIK.

Can You Get LASIK Twice?

Yes, it is possible to undergo LASIK eye surgery twice. However, very few people – approximately 10% – require a second procedure.

The initial LASIK surgery permanently changes the shape of the cornea to correct vision. For most patients, this correction remains stable long-term, providing clear vision for life.

However, for a small percentage of people, the eyes and vision can change over time. Nearsightedness may gradually increase again or the original LASIK correction becomes less effective. In these cases, a second treatment may be warranted to touch up the vision and maintain the benefits of LASIK.

According to leading LASIK surgeons, if an enhancement is needed, it is usually performed 5 to 10 years after the initial procedure. The time frame depends on when vision changes become bothersome enough for a patient to consider a second treatment.

Can I Get LASIK Again After 10 Years?

Yes, you can undergo LASIK again 10 years after your original surgery if your vision has regressed. Ten years post-LASIK, it’s common for some degree of prescription change or regression to have occurred.

During your LASIK consultation, your ophthalmologist will determine if you are a good candidate for an enhancement based on a variety of factors, including the health of your eyes and the amount of corneal tissue available.

In most cases, getting LASIK again 10 years later is safe and effective when performed by an experienced refractive surgeon. It can help you maintain excellent vision for years to come.

How Many Times Can You Have LASIK?

There is no specific limit on the number of LASIK procedures you can have. However, very few people undergo more than two surgeries in their lifetime.

The main factor affecting the number of LASIK enhancements is corneal thickness. To perform LASIK safely, you need adequate corneal tissue. The surgeon creates a corneal flap during the procedure, so repeat treatments remove additional tissue.

If the cornea becomes too thin from multiple LASIK surgeries, it increases the risk of complications. Most surgeons will limit enhancement procedures once the cornea reaches a minimal thickness threshold. This is usually after two or three LASIK treatments, in rare cases.

Can You Get LASIK 20 Years Later?

It is possible to get LASIK again 20 years after your initial procedure. By this time, most patients have noticed some change in their vision, such as age-related presbyopia or myopia regression. An enhancement may be performed to recalibrate vision and reduce dependence on glasses or contacts.

The key is ensuring you still have enough corneal tissue for safe LASIK treatment. The surgeon will measure your corneal thickness and map the cornea to determine if a flap can be safely created. As long as you meet the basic criteria, repeat LASIK 20 years later can successfully maintain excellent vision.

Does LASIK Last a Lifetime?

While LASIK aims to provide permanent vision correction, the results may diminish over time for some people. On average, over 90% of patients have 20/20 vision or better 10 years after LASIK surgery. Long-term studies found over 50% still achieve 20/20 vision 25 years post-LASIK.

For the vast majority of patients, the effects of LASIK will provide clear vision for life. However, it‘s possible that vision can regress gradually years later or new conditions like cataracts or macular degeneration arise. If vision changes become significant, an enhancement may restore sharp vision.

Why Does LASIK Only Last 10 Years?

It’s a misconception that LASIK only lasts 10 years. For most patients, LASIK results are stable for decades.

However, studies do show enhancement rates of around 10% at the 10-year mark post-LASIK. This means 10% of patients have regression or prescription change that makes an enhancement helpful to maintain optimal vision.

The eyes and vision continue to change with age, so some reduction in effect is normal. Also, LASIK is unable to halt age-related presbyopia, which causes reading vision to deteriorate. An enhancement can touch up the correction but doesn’t stop the aging process.

Is LASIK Worth It After 40?

LASIK can be an excellent option for vision correction after 40. By this age, most people have started experiencing presbyopia, or difficulty focusing on close objects. LASIK can eliminate the need for glasses or contacts to see far and mid-range, while reading glasses address near vision.

One key consideration is that the healing time may be longer after age 40. However, LASIK is still safe and effective when performed by an experienced surgeon. The long-term vision improvement and freedom from glasses and contacts make LASIK worthwhile for most patients in their 40s.

Is LASIK Worth It After 50?

LASIK remains an effective procedure for vision correction after age 50. At this stage of life, reading glasses will still be required for presbyopia. But LASIK can deliver excellent distance and middle vision for daily activities like driving, watching TV, golfing, and more.

The LASIK consultation will evaluate your eye health and corneal thickness to determine candidacy. As long as your eyes are healthy, LASIK can successfully and safely reduce dependence on glasses and contacts after 50. For active, busy lifestyles, the benefits make LASIK worthwhile.

Is LASIK Worth It After 60?

Even after age 60, LASIK may provide meaningful improvement in vision and quality of life. At this age, reading glasses will definitely be needed, and you may also require bifocals or progressives for changing vision.

LASIK cannot restore youthful vision, but it can help optimize distance vision at a time when cataracts or other issues may be emerging. An experienced surgeon can determine if LASIK is a wise choice to maximize vision potential after age 60.

How Many LASIK Procedures Can You Have?

Most people only require one LASIK procedure in their lifetime. Only about 10% of patients need an enhancement.

In rare cases, a person may undergo three or at most four LASIK treatments over their lifetime. However, this is exceedingly uncommon and only done if the patient has very thin corneas to start with that can withstand multiple flap procedures.

After three or four LASIK surgeries, the cornea is often too compromised to safely perform additional enhancement surgery. At that point, lens implants may be the only remaining vision correction option.

Are Lifetime Enhancements Worth It?

Some LASIK providers offer “lifetime enhancement” guarantees, allowing free touch-ups whenever needed after the original procedure. This gives peace of mind, but is the extra cost worth it?

For most patients who get LASIK, enhancements are never needed. Less than 10% require a second treatment 5 to 10 years later. The likelihood of needing three or more lifetime enhancements is extremely low.

Also, you would still need to meet the standard criteria for LASIK to qualify for an enhancement. consult with your provider about the specifics and costs of their lifetime enhancement policy to see if it provides value. Often, it is not necessary after uncomplicated LASIK.

Can LASIK Be Repeated If Your Vision Gets Worse?

If your eyes and vision continue changing after your initial LASIK treatment, an enhancement may be performed to touch up the results. Keep in mind that LASIK only affects the cornea – it does not prevent normal eye aging processes or diseases.

During your follow-up exams, your ophthalmologist will determine if any vision changes are significant enough to affect your daily functioning. If so, they can evaluate your candidacy for a second LASIK procedure to refine your vision back to 20/20 or better.

In most cases, vision after a LASIK enhancement will still be markedly improved compared to wearing glasses or contacts before your original surgery. Repeat procedures help you maintain excellent vision for years to come.

Is a LASIK Touch Up Possible?

Yes, LASIK enhancement or touch-up procedures are commonly performed to further improve vision if you are unsatisfied with your initial results. This allows the surgeon to fine-tune the correction and provide crisper vision.

LASIK touch ups are easiest within the first year after initial treatment, when the corneal flap is still optimally healed. Enhancements may also be safely performed years later in most cases. The key is having adequate corneal tissue for another LASIK procedure.

Just like original LASIK, enhancements are customized during a computerized planning session to best correct any remaining refractive error. For most patients, touch up results meet or exceed expectations.

Can Nearsightedness Return After LASIK?

One of the most common reasons people require a LASIK touch up is regression of myopia (nearsightedness) over time. After LASIK, it‘s possible for nearsightedness to gradually return as the eyes grow slightly longer or the cornea regresses.

Doctors are not always certain why some postoperative LASIK patients experience regression while most maintain stable vision long-term. Careful screening and advanced treatment planning aim to prevent regression. Enhancement surgery can successfully treat regression if it occurs.

Can PRK Be Repeated?

PRK or photorefractive keratectomy is a laser eye surgery similar to LASIK. Like LASIK, PRK typically provides permanent vision correction with over 95% of patients seeing 20/20 or better.

In the rare instance vision changes after PRK, a second treatment may be performed. The repeat PRK procedure involves removing the epithelium again to access the cornea for laser reshaping, just like the original surgery.

Multiple PRK procedures are considered safe when sufficient corneal tissue remains. PRK does not cut a flap like LASIK, so more treatments may be possible. However, most PRK patients achieve stable, long-term results after one surgery.

Can I Get 20/20 Vision With PRK?

Yes, PRK can correct nearsighted vision to 20/20 or better in the majority of patients. According to clinical studies, approximately 90% of people see 20/20 one year after PRK surgery. Over 95% achieve 20/40 vision or better.

Similar to LASIK, the goal of PRK is to optimize visual acuity and reduce dependency on glasses or contacts. For suitable candidates, PRK reliably provides excellent vision ranging from 20/15 to 20/20 after healing is complete.

What Is The Oldest Age For LASIK?

There is no strict maximum age limit for LASIK. More important than age alone is the health of your eyes. LASIK has been safely performed on healthy patients in their 60s, 70s, and beyond.

The key criteria are:

• Your prescription must be stable for at least one year before LASIK.

• You must have adequate corneal thickness for flap creation.

• You should be free of eye diseases like advanced cataracts or glaucoma.

• Your ophthalmologist must determine you are likely to achieve significant vision improvement.

When these conditions are met, LASIK can successfully correct vision at any adult age. Be sure to discuss your options fully with your eye doctor.

What Is The Highest Prescription Limit For LASIK?

The FDA has approved LASIK treatment for nearsightedness up to -12 diopters, farsightedness up to +6 diopters, and astigmatism up to 6 diopters.

However, LASIK surgeons often set their own limits based on experience and equipment capabilities. Many now safely treat higher prescriptions beyond the FDA guidelines.

During your evaluation, advanced corneal mapping will determine if your corneas have sufficient thickness for safe LASIK. If so, most moderate to high prescriptions can be effectively treated. It’s worth discussing your options with a refractive surgery specialist.

Can LASIK Correct Astigmatism?

Yes, LASIK is frequently used to reduce or eliminate astigmatism. The laser treatment targets irregularities in the corneal curvature that cause distorted vision.

Studies show LASIK safely and effectively treats astigmatism up to 6 diopters, and often higher amounts. Over 85% of patients with astigmatism achieve 20/20 vision or better after LASIK. Glasses or contacts are typically no longer needed.

Advanced topography-guided LASIK offers excellent results for higher astigmatism. Be sure to discuss your degree of astigmatism with your LASIK surgeon.

How Many Patients Are Not Candidates For LASIK?

According to surveys by refractive surgery societies, approximately 15-20% of people hoping to get LASIK are considered ineligible. The most common reasons include:

• Corneas are too thin for safe LASIK

• Prescription is outside the treatable range

• Preexisting eye disease or condition

• History of unstable prescriptions

• Unrealistic expectations of visual outcomes

• Systemic health issues

A comprehensive exam and evaluation will determine if you meet the requirements for safe, successful LASIK. Even if LASIK is not recommended, other vision correction options like PRK or ICL may be available.

At What Age Is LASIK Most Effective?

The ideal age for best LASIK results is generally between ages 25 and 40. By your mid-20s, your eye prescription has usually stabilized, which is important for LASIK success. This age group also experiences the most rapid healing and visual recovery after surgery.

LASIK is safe and effective outside this range, but under 25 the prescription may still be changing. Over 40, healing time is slower and age-related eye issues like presbyopia begin manifesting. Your doctor will help determine the optimal time for you personally to undergo LASIK.

Is LASIK Still Worth It Despite Being Less Popular Today?

LASIK procedures are not as widely performed today as compared to the early 2000s. The volume of LASIK surgeries declined with the Great Recession and never fully rebounded.

However, LASIK remains an extremely effective option for vision correction producing life-changing results. Approximately 600,000 Americans still choose LASIK every year for freedom from eyeglasses and contacts.

For suitable candidates who value lifestyle benefits like clear vision 24/7, LASIK delivers lasting value and remains fully worth the investment. Improved technology only increases its capabilities over time.

Conclusion: Should You Get LASIK Again?

Repeat LASIK procedures are possible when vision changes over time. For the right patients, enhancements can reliably sharpen vision back to 20/20 and maintain the benefits of a LASIK lifestyle.

Careful screening for adequate corneal health and thickness is key to determine candidacy for safe LASIK retreatment. An experienced refractive surgeon can advise you on the smart timing for an enhancement procedure if needed.

While most LASIK patients never require a second treatment, the option for touch up surgery is reassuring. LASIK aims to deliver permanent vision correction, but it‘s nice having access to the latest technology and techniques if your eyes change down the road.
