Patients preparing for LASIK surgery often ask us, “How many times can you have LASIK?” While it’s natural to want all the information you can have when it comes to your vision, only 5% of patients consider getting additional laser surgery post-LASIK. 

LASIK is an incredibly safe and common procedure with permanent results. What follows is a brief overview of what circumstances might lead to the need for additional LASIK or LASIK enhancement surgery. 

Can LASIK eye surgery be repeated? 

Yes, most patients can undergo LASIK surgery multiple times. However, the answer to “How many times can you have LASIK?” changes from patient to patient, depending on the health and thickness of their corneas. 

Since most doctors opt to perform LASIK on patients who are over 18 and whose prescription has stabilized, most LASIK candidates don’t need additional LASIK treatment. This is because their eyesight won’t undergo many changes post-surgery. This fact is especially true of patients over the age of 40.

For the small percentage of clients whose vision does change after LASIK, enhancement procedures such as PRK after LASIK are available. 

In addition, doctors should warn patients with high prescriptions that they have a greater likelihood of needing additional treatment long before the surgery takes place. (Check out our post “Is my vision too bad for LASIK?” if you’re concerned that you might fit into this latter category.) 

Can LASIK be repeated years later? 

LASIK can be repeated from the end of the normal LASIK recovery timeline to many years after the surgery. Again, exactly how many times you can have LASIK will depend on the health and thickness of your cornea. 

Whether you anticipate needing additional LASIK or a LASIK enhancement, making sure that you follow through with all of the best practices while preparing for LASIK and during LASIK surgery post-operative care improves the likelihood of a successful first and second surgery.   

Is LASIK safe long-term? Can your vision get worse after LASIK?

The effects of LASIK surgery are permanent. Your LASIK can’t “wear off.” However, the health of your eye can change, which in turn can make your LASIK less effective. The vast majority of these eye health changes occur independently of your LASIK procedure — meaning they would likely have happened whether you chose to have LASIK or not.

For example, many people experience presbyopia (the hardening of your eye’s lens) as their eyes age and as they begin to wear reading glasses to make up for presbyopia-related vision loss. (Good news! Presbyopia, also known as near vision, can be treated.)  

Concerned about the safety of LASIK? Talk with the doctors at Eye Center of Texas. 

Around 95% of LASIK patients experience life-changing improvement in their vision after their first (and only) procedure. One way to ensure the success of your LASIK procedure is to go to a reputable LASIK surgeon. 

If you want the benefits of LASIK but are worried about the procedure, request an appointment at Eye Center of Texas, which is home to some of the best LASIK surgeons in Houston, Texas. Our team of professionals will walk you through the process step-by-step and take the time to answer any questions you may have.

If someone close to you is going to have LASIK eye surgery on one or both of their eyes, it’s natural to want to help. Yet while there are plenty of resources out there that outline pre-op best practices and post-op LASIK recovery timelines, it’s harder to find a primer for someone who wants to help look after a recent LASIK patient.  

There’s actually a lot you can do to help care for someone who is about to have/has just had LASIK surgery, even when LASIK patients are able to return to (most) activities 24 hours after the surgery.  

Here are some of our favorite recommendations for ways to make the LASIK experience (even) easier. Of course, these tips are also helpful if it’s you who is having LASIK done and you’re looking for some ways to make the experience as smooth as possible.

1. Research LASIK surgeons in your area and familiarize yourself with the LASIK process

If your friend/partner has just begun their LASIK journey, you would not be remiss in helping them research their LASIK options. Research the best LASIK surgeons in Houston by reading the reviews, checking their years of experience, and making note of their accreditations, awards, etc.

After your loved one has their consultation, learn whether or not their vision is too bad for LASIK, and schedules a surgery date. Learn the answers to the following questions: What are the precautions to take after LASIK eye surgery? What can you NOT do after LASIK? What eye drops can you use after LASIK?

By taking the time to know a little bit (or a lot) about LASIK best practices, you may be able to put your loved one’s mind at ease on the day of the surgery, especially if they’re feeling nervous. The following materials will help you beef up on your LASIK knowledge:

• LASIK FAQs
• LASIK Surgery Prep
• Can I swim after LASIK?
• Things to avoid after LASIK

2. Pre-purchase extra eye drops

A doctor will prescribe medicinal eye drops for before and after LASIK surgery, but almost all patients experience some level of dry eye after they no longer need to take those medicinal eye drops. Having a box of preservative-free eyedrops on-hand for when that time comes can save your loved one an inconvenient, dry-eyed trip to the convenience store.

3. Pre-purchase Tylenol PM or an equivalent medicine

LASIK patients are recommended to sleep as much as possible the day of their LASIK procedure. While the Valium that most doctors give their patients pre-op will likely knock them out for a few hours after the operation, many patients have noted needing a little extra help getting to sleep later in the day.

4.  Pre-purchase and prepare meals

Since patients are told to keep their eyes closed as much as possible the day of the surgery, it’s wise to have meals pre-purchased and, if possible, prepared. (The latter is especially true if the patients will be spending some of the recovery time alone.) If the patient has young kids, taking this additional step will be extra helpful when you’re short a pair of helping hands at mealtimes.

One final pro tip for your post-LASIK kitchen life: Now is the time to use all of those paper plates you’ve had lying around since last Halloween and all the pre-wrapped plasticware from takeout that you have shoved in the back of your utensil drawer.

5. Pre-purchase/rent entertainment that doesn’t require visuals

Noticing a theme? Many post-LASIK care tips involve a little bit of prep, and this is especially true of entertainment for the day of the surgery. LASIK surgery often takes place in the morning, it’s recommended that patients keep their eyes closed for the first 24 hours after surgery. That means they’ll be spending the entire day with their eyes closed — and if they can’t sleep, sitting in the dark can get really boring really quickly.

We recommend getting pre-purchasing entertainment that doesn’t involve the heavy use of screens. Popular options include podcasts, audiobooks, and music. If you want to go analog, you could also just read out loud to the person who just had LASIK.

Slightly more eccentric suggestions include “listening” to a movie you’ve seen a million times so that you can visualize it OR “listening” to a movie you’ve seen a million times… but in a language that you’re trying to learn!

6. Make plans for phone use

Patients should avoid looking at screens for the first 24 hours after LASIK, including phone screens. If they are comfortable with it, you can read their texts for them or, if they have an iPhone, they can have Siri read their messages to them.

The next day, using your phone after LASIK is permitted (although we do advise continued avoidance of screens). If your friend/partner need to use their phone, they may find some relief by making their phone’s text size bigger and by turning down the screen’s brightness.  

7. Provide support the morning of the surgery

Even the most stoic of patients may feel a little nervous the morning of their procedure. For some patients, just having a friendly face nearby may help relieve stress and make the difference between a frazzled pre-op experience and a smooth one.

Other patients may want to have someone who will remind them to bring everything they need, eat, take a shower (to avoid getting water in their eyes later on), and wear comfortable clothes (so that they can go to sleep right after the surgery).

8. Provide transportation

Your friend/partner will, at the very least, need a ride home from the clinic after their surgery; they won’t be able to open their eyes to drive, and Eye Center of Texas will not release a patient to a taxi driver (including Lyft and Uber). That said, most patients prefer to bring someone who will be there throughout the whole procedure. Since the surgery takes only 5 minutes per eye, you won’t be in the waiting room for long!

9. Help keep track of their eye drop schedule

An eye surgeon should prescribe at least one (probably two) types of eye drops that must be taken at various times on the day of the surgery, as well as in the following days. Since the LASIK surgery participant will be sleeping often on the day of the procedure, patients have found it helpful to have someone nearby to make sure that they wake up at the appropriate times and use the appropriate drops. Helping them pre-set alarms can also be helpful.

10. Help with the pets and/or kids  

Does the LASIK patient’s dog need to be taken outside? Does their cat need its litter box cleaned? Do their children need to be picked up from school? Are either the children or the pets mischievous enough to get into or chew up eye drop bottles? Has everyone been fed? Time to chip in!

11. Help with the dishes

If you didn’t want to use the paper plates and plastic utensils mentioned in tip #4, doing your loved one’s dishes can be a huge help. Not only will it help them keep water from getting into their eyes, but it will allow them to continue to rest as well.

12. Encourage rest, rest, and more rest!

At Eye Center of Texas, we are frequently asked, “How can I heal faster after LASIK?” The recovery time for LASIK is extremely short, but for the best healing results, we recommend lots of rest, preferably with your eyes closed. It can be tempting for some LASIK patients to spend a “quick 5 minutes” on their phone the day after the procedure, only to then realize that they’ve been on it for an hour.

So if you’re looking for one big way to help your friend/partner recover from LASIK, perhaps the best thing you can do is to encourage them to relax and enable them to rest until at least 24 hours has passed.

13. Make note of follow-up appointments

This one is more for the spouses and partners of LASIK patients, but it’s still worth mentioning. Your doctor should schedule a one day, one week, and one-month follow-up for your LASIK procedure. These follow-ups allow the surgeon to monitor the progression of the LASIK patient’s recovery and the overall health of their eyes.

14. Celebrate the little things!

Each LASIK patient will begin to see better at their own pace. Some patients can see more clearly immediately after the surgery, and others notice a difference after they wake up the next morning.

And when excitement about the “big change” wears off, know that you and your loved one will continue to celebrate the little things now that they are glasses and contacts free. Walking in the rain? No problem! Taking the lid off of a pot that will steam? Sure! Wearing non-prescription sunglasses to the beach? Finally!

Most doctors recommend using preservative-free eye drops after LASIK eye surgery. That’s because dealing with dry eyes is a pretty standard part of post-operative care for LASIK eye surgery. But why exactly should you use preservative-free eye drops after LASIK surgery, as opposed to other types of eye drops?

Discover the ins and outs of using eye drops after LASIK surgery and why preservative-free eye drops are your best choice.

Why should you use preservative free eye drops after LASIK?

You don’t technically have to use preservative-free eye drops, but preservative-free eye drops are definitely the best artificial tears to use after LASIK in terms of what’s best for your eye health.

Some companies use preservatives in their eyedrops to prevent a deterioration of the artificial tear and to keep your eyes free from contamination. While that may sound good on the outset, those same preservatives are toxic to your eye and cause irritation and inflammation.

Recently, some companies have begun selling drops that claim to be “preservative free on contact.” These companies argue that the toxins in the preservative disappear quickly enough to not affect the eye. In reality, the dissipation of the toxins in these drops relies on several factors (ambient light, for example), and if any of these factors is missing, the toxins remain in your eye.

In short, the toxins in eye drops with preservatives can undo the healing and relief you’re trying to achieve. Since your eyes are especially sensitive post-op, truly preservative-free eye drops are the best artificial tears after LASIK.

How often should I use artificial tears after LASIK?

Let’s say you’ve read our post on how to prepare for LASIK and have diligently gone out and gotten the preservative-free eye drops after LASIK. Now what?

Every eye patient is different, but most patients will receive prescription eye drops to take directly before and after their LASIK surgery. After the first day, you can use preservative-free eye drops after LASIK as much as you would like. The standard recommended usage is 4 times a day.

How long after LASIK can I stop using eye drops?

We are often asked how long to use preservative-free eye drops after LASIK. Our typical answer? It depends. Every LASIK patient experiences different levels of dryness and can use preservative-free eye drops after LASIK until the dryness abates. However, if you experience extreme and persistent dryness, do bring it to the attention of your doctor.  

If you plan on wearing contacts after LASIK, note that there are also types of contacts that can help reduce dryness!

Depend on Eye Center of Texas for all your LASIK questions & needs

With over 75,000 successful LASIK procedures to our name, you can rest assured that your vision is in good hands at Eye Center of Texas. Call us at 713-395-1515 or request an appointment online today for a LASIK consultation.

Over the years, we’ve noticed that one question, in particular, seems to come up often during our LASIK consultations: Does the corneal flap heal after LASIK?

While the informed answer to that question has some nuances (which we’ll cover here), the essential answer is: Yes. In fact, the LASIK flap dislocation percentage is less than one half of 1%.

If you’re a LASIK candidate and follow through with the standard post-operative care for LASIK eye surgery, chances are that the only thing you’ll have to worry about is after LASIK is what type of fancy non-prescription sunglasses you’re going to buy.

Now let’s get to why that’s true.

Why is there confusion about the corneal flap healing after LASIK?

Many people are afraid of putting contacts in their eyes, let alone electing to have LASIK eye surgery. Every few years, someone plays off of those fears and raises suspicion about the integrity of the LASIK procedure.

One of the more recent scares concerned whether or not the corneal flap actually heals. As this rumor was perpetuated, the subtleties of the corneal flaps healing process (which we’ll get into in a moment) were only partially or incorrectly explained.

The surgeons at Eye Center of Texas have performed over 75,000 successful LASIK surgeries. They can and do attest to the fact that the surgery is perhaps the safest and most researched elective surgeries available.

But you don’t have to take our word for it. After conducting many studies (including this one) the U.S. military decided that LASIK was so beneficial to a soldiers’ performance that they’ve had the procedure performed on hundreds of thousands of U.S. military personnel.

How do your eyes heal after LASIK?

Alright, so how does the corneal flap heal after LASIK? The corneal flap heals in different ways at different parts of the flap. We’ve broken it down for you here:

• Epithelial layer: Your epithelium is the very, very thin layer found on the surface of the cornea. It begins healing almost immediately after the flap has been replaced and is the reason that you don’t feel a “line” between the flap and the rest of your eye.
• Stroma: Your stroma is what makes up most of your cornea’s mass. Stromal healing takes place along thickest parts of the flap’s edges.
• Bottom layer: Here is where the recent round of, “Does the corneal flap heal after LASIK” originates. During the corneal flap’s healing process, the bottom layer of the flap does not “join” with the surface underneath it… which is actually a very good thing. If it did, you’d be stuck with an opaque layer of collagen that would do the exact opposite of what LASIK is supposed to do: improve your sight.  

If you’re thinking, “That’s all well and good, but how long does it take the flap to heal after LASIK?” rest assured. Your corneal flap begins healing immediately after the surgery. It will be mostly healed after 24 hours after your procedure. For more information about healing times, check out our post on the LASIK recovery timeline.

How do I know if my corneal flap moved?

Let’s get down to the direct questions. Can the flap be moved after LASIK? And if so, how can you tell if it’s moved? Like any surgery, LASIK surgery does come with risks. After the first day of healing your flap can move, but only under extreme circumstances. Check out a timeline to learn more about LASIK recovery.

What do we mean by extreme circumstances? Let’s say a LASIK patient is involved in a high-impact accident on or around their eyes. In this case, there is a small but real chance that the flap can move.

Now let’s say you accidentally rubbed your eyes a few days after LASIK, and you’re concerned that you’ve moved the flap. In this case, it’s extraordinarily unlikely that your flap will move.

Here’s a general rule to live by with regard to corneal flap dislocation: If you’re not sure whether or not your corneal flap has moved, then your corneal flap has not moved. In the very unlikely event of corneal flap dislocation, patients will feel immediate pain and should seek emergency treatment.

Why would I need reading glasses after LASIK?

LASIK surgery addresses refractive errors in your vision: nearsightedness, farsightedness, and astigmatism. Standard LASIK procedure does not address presbyopia, which is the hardening of the eye that’s a natural part of your eye’s aging process. That’s why some LASIK patients will eventually need to wear glasses to read as they get older.

Patients concerned about presbyopia (also known as near vision) can find more helpful information in our posts on LASIK eye surgery for presbyopia and resource page for additional presbyopia solutions.

Your step-by-step guide to recovering from LASIK eye surgery

Congratulations! You’ve made the decision to have (or maybe you’ve just had) LASIK eye surgery, and now, you’re one step closer to long-term clear vision. Having an understanding of what a LASIK recovery timeline looks like will help make the next few months smoother for you.

As with our LASIK consultation preparation guide, this guide is intended to walk you through what you should and shouldn’t do after LASIK surgery.

Please note that this LASIK Recovery Timeline is an approximation of what a typical LASIK recovery looks like. This timeline, along with the recommendations shared, may vary from your own recovery process, as well as your doctor’s instructions.

The day of LASIK surgery

Step 1: Get home safely

One of the most important steps on your LASIK recovery timeline takes place right after surgery: the ride home. Your doctor will likely have given you a mild sedative to keep you comfortable during the procedure. After the procedure is completed, this sedative can leave you too impaired to drive for up to several hours. Because of this, it’s important to make sure you have a ride home, and if all else fails, make sure you have someone to dirve you home (note, Eye Center of Texas cannot release you to an Uber or Taxi driver).

Step 2: Rest

How long should you sleep after LASIK? Your doctor will likely suggest that you rest for the first few hours after your surgery (typically, 2-4 hours). In other words, no Olympic training, dissertation writing, or late-night partying — only rest!

Step 3: Take these precautions

• When you’re resting, consider wearing an eye patch over your eyes. Doing so will help you avoid rubbing your eyes and opening the corneal flap as a result. This is one of the most important LASIK recovery tips for you to follow.
• Avoid strenuous activity and exercise. Do not play contact sports.
• Do not shower for the first 24 hours after your surgery.
• Do not swim.
• Do not wear contact lenses, even if your vision is blurry.
• Do not wear makeup or apply creams to your face.

Eye and vision status check-in:

• Directly after the surgery, patients might experience some eye pain, bloodshot eyes, weeping, sensitivity to light, halos, and irritation (it might feel as if there is a grain of sand in your eye). However, you must remember to avoid rubbing your eyes — despite the irritation.
• Can you see immediately after LASIK? After three hours, your vision may start to clear up, but it could also take longer. Both situations are normal.
• If you’re wondering, “How long after LASIK can I see 20/20?” or “How long does it take for vision to improve after LASIK?” it’s important to keep in mind that there isn’t a straightforward answer to this question. Some patients will experience clear vision a few hours after surgery, and for some, it could take a few days. Others might fluctuate between clear vision and blurry vision for up to six months, and some might notice their vision improve gradually for the next six months or so.
• If you experience any eye pain, call your doctor immediately. This statement holds true for the entire LASIK healing timeline.

24 – 48 hours after LASIK surgery

Step 1: Have someone take you to your follow-up appointment

Your doctor will likely have you scheduled for a follow-up appointment 24-48 hours after your procedure. During this appointment, they will check your eyes and test your vision. It’s likely they will also prescribe you medicated, lubricating eye drops (this is especially true if you’re experiencing dry eyes, a side effect that typically occurs for the first weeks or months after LASIK).

Your doctor will also be able to advise you as to whether or not it is safe for you to drive. Their decision will be based on the legal vision requirement for driving in Texas, which is 20/40.

Step 2: Rest, but feel free to recommence with the following (unless your doctor states otherwise):

• Shower, but try to keep soap, shampoo, conditioner, and other chemicals out of your eye.
• Return to your normal work routine, so long as it does not involve strenuous physical activity.
• Drive, but only if your doctor states that it’s legal for you to do so.
• Take a flight, but note that the low humidity typically found in airplanes will make your eyes more prone to drying out.

Step 3: Continue to take the following precautions:

• Wear an eye patch over your eyes to help you avoid rubbing your eyes and opening the corneal flap as a result.
• Wear sunglasses. How long do you have to wear sunglasses after laser eye surgery? Most doctors recommend that you continue to wear sunglasses when you go outside for at least 2 days after your procedure.
• Avoid strenuous activity and exercise. Do not play contact sports.
• Do not swim. You’re going to hear this a lot during the next few steps. For more information, check out our blog on swimming after LASIK.
• Do not wear contact lenses, even if your vision is blurry.
• Do not wear makeup or apply creams to your face.

Eye and vision status check-in:

As your LASIK corneal flap is healing, your eyes will likely still be irritated. Meanwhile, your vision may or may not begin clearing. If the latter is true for you, don’t panic. Vision fluctuation after LASIK is typical after LASIK surgery, and part of your LASIK recovery time may involve some blurred vision.

At the 1st week mark after LASIK

Step 1: Rest, but feel free to recommence with the following (unless your doctor states otherwise):

On the 3rd day after your procedure, you should be able to go outside without sunglasses. However, you may still be sensitive to light. It’s always wise to wear sunglasses when outside, so being extra cautious about wearing sunglasses will do no harm.

Step 2: Continue to take the following precautions:

• Wear an eye patch over your eyes to help you avoid rubbing your eyes and opening the corneal flap as a result.
• Avoid strenuous activity and exercise. Do not play contact sports.
• Do not swim.
• Do not wear contact lenses, even if your vision is blurry.
• Do not wear makeup or apply creams to your face.

Eye and vision status check-in:

At this point in your LASIK recovery timeline, your eyes may still have some irritation and sensitivity to light. Difficulty driving at night may also still occur. While you probably won’t feel far along on your LASIK recovery timeline, you’re definitely well on your way to full recovery and better vision.

2 weeks – 1 month after your LASIK procedure

Step 1: Continue to go to your LASIK follow-up appointments .

Step 2: Continue to take the following precautions:

• Wear an eye patch over your eyes to help you avoid rubbing your eyes and opening the corneal flap as a result.
• Do not play contact sports.
• Do not swim. If you need to swim for any reason, consult your doctor first. Do not go swimming without goggles.
• Do not wear contact lenses, even if your vision is blurry.

Eye and vision status check-in:

If everything has continued to go well, your eyes shouldn’t be causing as much irritation as they were toward the beginning of your LASIK recovery timeline. Depending on your eyes, however, your vision may still be in the process of clearing up.

2 – 6 months after LASIK

Step 1: Continue to go to your LASIK follow-up appointments

After six months, you and your doctor will discuss how often you will need a check-up. These will vary but generally occur every one to two years. After six months, you and your doctor will also be able to tell if LASIK enhancement (PRK) would further improve your vision.

Step 2: Feel free to recommence with the following at the designated time (unless your doctor advises you otherwise):

• 4-5 weeks after surgery: Return to your standard exercise routine and contact sports, if you play them.
• 4-5 weeks after surgery: Swim, preferably in your own pool. Swimming in public pools, hot tubs, water parks, and natural bodies of water will increase your chances of getting an infection.
• 4-5 weeks after surgery (or when irritation ceases): Stop wearing an eye patch if you are no longer tempted to rub your eyes.
• 2-3 months after surgery: Get fitted for contacts, if you need them.

Eye and vision status check-in:

Here we are at the end of your LASIK recovery timeline. You made it! The reason we include six months in the LASIK recovery timeline is that your eyes are healing right up into the sixth month. For the vast majority of patients, all LASIK side effects (irritation, difficulty driving at night, light sensitivity, glare, etc.) should have stabilized by this point. The main exception to this rule is patients with nearsightedness, who may require a longer recovery period.

Have you ever wondered, “Is my vision too bad for LASIK?” or “Can you get LASIK with really bad vision?” If so, Eye Center of Texas has some news that just might make your day. Technology has improved such that patients with severe vision impairments may be able to achieve improved vision with LASIK eye surgery.

Learn about the wide range of eye power levels compatible with LASIK and other requirements for LASIK eye surgery today.

Understanding refractive errors and diopters

There are a lot of misconceptions around who can and can’t have LASIK eye surgery, which is why we receive so many questions like “Is my vision too bad for LASIK eye surgery” or even, “Is my vision too good for LASIK?”

The confusion probably stems from a lack of understanding as to how we measure maximum and minimum prescription ranges for LASIK. These ranges are determined by the refractive errors specific to each patient’s eyes. Refractive errors — the light refraction errors created by a misshapen lens or cornea that cause common vision problems — are measured in diopters (D). Negative diopters indicate myopia (nearsightedness) and positive numbers indicate hyperopia (farsightedness).

What prescription is too high for LASIK?

When trying to find the answer to the question, “Is my vision too bad for LASIK?” patients often seek out specific diopter measurements standards. While some sites do provide these numbers, it’s extremely important to note that the range of diopters which LASIK can treat depends on the technology your surgeon uses. For that reason, we’ve given a more general overview of the appropriate prescription range for LASIK candidates.

• Myopia (Nearsightedness): Performing LASIK on eyes with myopia that is beyond a certain negative diopter measurement can cause nighttime vision problems and halos.
• Hyperopia (Farsightedness): Performing LASIK on eyes with hyperopia that is beyond a certain diopter measurement can cause nighttime vision problems and halos. The range of diopter measurements for farsightedness is smaller than that of myopia.
• Astigmatism (When both near and far objects are blurred): The astigmatism limits for LASIK are more variable. Each of the following has its own acceptable range, as is defined by your doctor.
  • Astigmatism combined with myopia
  • Astigmatism combined with hyperopia
  • Mixed astigmatism patients

For those of you who are curious about LASIK for astigmatism, we recommend reading our article, Can LASIK correct astigmatism.

What are the requirements for LASIK eye surgery?

Can LASIK give you 20/20 vision? Yes, it can. However, you must also meet other requirements outside of prescription limits in order to be a good candidate for LASIK. These include:

• Having corneal tissue that’s thick enough — approximately 420 microns — for LASIK. Most healthy eyes have corneas that around 550 microns thick.
• Your eye health, in general, must be in good standing
  • Your prescription must not change for 12 months
  • You must not suffer from glaucoma, dry eyes, or cataracts
  • You must have an average pupil size
• Women who are pregnant or nursing should wait to have LASIK.

If you meet all of these conditions, then you are likely an ideal candidate for LASIK eye surgery! However, even if you’re a perfect candidate for LASIK surgery, it’s important that you follow through with pre-LASIK preparation and choose a quality eye surgeon like those at Eye Center of Texas.

Do I have other laser eye surgery options for improved vision?

When your prescription or eye health disqualifies you from being a good LASIK candidate, it’s always worth speaking to your doctor about your other options.

For example, if you don’t qualify for LASIK, it’s possible that PRK eye surgery may be an option for you. PRK is LASIK’s predecessor and can have the same positive results as LASIK. It has different ranges of acceptable eye power and is available to some patients who do not meet all of the other requirements for LASIK eye surgery.

Occasionally, some patients even chose to have PRK LASIK enhancement after their original LASIK surgery.

20/20 vision (or better!) is possible with LASIK at Eye Center of Texas
